Brief history of different grading systems

In 1785, students at Yale were ranked based on "optimi" being the highest rank, followed by second optimi, inferiore (lower), and pejores (worse). At William and Mary, students were ranked as either No. 1, or No. 2, where No. 1 represented students that were first in their class, while No. 2 represented those who were "orderly, correct and attentive." Meanwhile at Harvard, students were graded based on a numerical system from 1-200 (except for math and philosophy where 1-100 was used). Later, shortly after 1883, Harvard used a system of "Classes" where students were either Class I, II, III, IV, or V, with V representing a failing grade. All of these examples show the subjective, arbitrary, and inconsistent nature with which different institutions graded their students, demonstrating the need for a more standardized, albeit equally arbitrary grading system.

In 1887, Mount Holyoke College became the first college to use letter grades similar to those commonly used today. The college used a grading scale with the letters A, B, C, D, and E, where E represented a failing grade. This grading system however, was far stricter than those commonly used today, with a failing grade being defined as anything below 75%. The college later re-defined their grading system, adding the letter F for a failing grade (still below 75%). This system of using a letter grading scale became increasingly popular within colleges and high schools, eventually leading to the letter grading systems typically used today. However, there is still significant variation regarding what may constitute an A, or whether a system uses plusses or minuses (i.e. A+ or B-), among other differences.

An alternative to the letter grading system

Letter grades provide an easy means to generalize a student's performance. They can be more effective than qualitative evaluations in situations where "right" or "wrong" answers can be easily quantified, such as an algebra exam, but alone may not provide a student with enough feedback in regards to an assessment like a written paper (which is much more subjective).

Although a written analysis of each individual student's work may be a more effective form of feedback, there exists the argument that students and parents are unlikely to read the feedback, and that teachers do not have the time to write such an analysis. There is precedence for this type of evaluation system however, in Saint Ann's School in New York City, an arts-oriented private school that does not have a letter grading system. Instead, teachers write anecdotal reports for each student. This method of evaluation focuses on promoting learning and improvement, rather than the pursuit of a certain letter grade in a course. For better or for worse however, these types of programs constitute a minority in the United States, and though the experience may be better for the student, most institutions still use a fairly standard letter grading system that students will have to adjust to. The time investment that this type of evaluation method requires of teachers/professors is likely not viable on university campuses with hundreds of students per course. As such, although there are other high schools such as Sanborn High School that approach grading in a more qualitative way, it remains to be seen whether such grading methods can be scalable. Until then, more generalized forms of grading like the letter grading system are unlikely to be entirely replaced. However, many educators already try to create an environment that limits the role that grades play in motivating students. One could argue that a combination of these two systems would likely be the most realistic, and effective way to provide a more standardized evaluation of students, while promoting learning.

Important Notes

You can use our grade calculator to calculate the final exam grade you will need to achieve the overall course grade you desire. Our calculator requires you to enter the current percentage grade you have currently obtained for that course together with the weight of the final exam as a percentage value. However, if you do not know what your current grade is, for the question "Do you know your Current Grade?" select the answer "no." Enter the grades you have received for all of your assignments, homework, test, labs, and anything else that contributes to your final grade, as well as the weight of each grade. Our grade calculator will automatically calculate not only your current grade but the grade you need to achieve on your final exam to achieve the overall course grade you desire. In addition, both the minimum and maximum course overall grades will be provided.

Once you have entered the information required, the system will generate both a table and a chart that show the different final exam grades you may obtain as well as the overall course grades that go with them.

Inputting Data in our Grade Calculator

When entering your current grade and the weight of your final exam, our calculator will assume that your current grade has been based on the weight of the course prior to your final exam and calculates it as the input weight subtracted from 100%. If your current grade hasn't taken your coursework into account, the generated results will not be accurate.

Similar to the above, if you don't know what your current grade is and you enter both the coursework grades and the associated weights into the calculator, the calculator will automatically calculate your current grade and the weight of the final exam. In this situation, the weight of your final exam is calculated by taking the sum of the weight of your course work subtracted from 100%. With that in mind, if you enter too many or not enough assignments, the weight of the final exam that is calculated will most likely not match the actual weight of the final exam in your chosen course.

Understanding how to calculate your current grade in a course is advantageous for planning what you need to achieve your goal’s overall course grade. The following Grade Calculator serves as an easy-to-use helpful tool to calculate your current grade of the course before the final examination.  

What is a Grade Calculator?  

A Grade Calculator is a free online tool designed to help students and educators determine academic grades based on entered scores and weights. It simplifies the process of calculating current grades, helping users navigate their academic journeys.   

The Grade Calculator helps students estimate the impact of each assignment on their course’s weighted average grade. That means the overall grade of a course depends on 2 main factors: the grade of each assignment (g) and the corresponding weight of each assignment (w).  

A Grade calculator helps you find your current average score in a course based on completed assignments up to the current point in the semester. The Final grade calculator then calculates the score you need to achieve in your remaining assignment (the final exam) to reach your desired grade of the course

How to Use a Grade Calculator?  

Using a Grade Calculator is a straightforward process that involves entering relevant information about your academic performance. To utilize this calculator, input your current percentage for each assignment, test, or exam, along with its respective weight towards your final grade. For each additional assignment, test, or exam, click on "Add Assignment." Your results will automatically update as you input each component , allowing you to track your progress throughout the course.  

Here's a step-by-step guide on how to use a Grade Calculator:  

Step 1: Input the Assignments.  

Users manually enter the name of each assignment, for example: Assignment 1, 2, 3, Homework, Final Exam, etc.  

Step 2: Input the grade.  

Enter their scores for each assignment, test, project, or other exam throughout the course. Each entry typically includes the earned percentage (10%, 30%, 50%, etc.), letter (A+, B-, D, etc.), or points (20, 50, 175, etc.).  

Step 3: Input the weight.  

Enter the weight of that assignment into the overall course grade. The weight indicates that different assignments may have varying impacts on the final grade. A final exam might have a higher weight than a small task.  

Step 4: Calculate the grade automatically.  

The tool then automatically calculates the cumulative grade based on the entered grades and weights. Users can see their current grade as well as how each assignment contributes to the overall grade.  

Step 5: Adjust as needed.  

Users can adjust grades or weights to see how changes impact the overall course performance. This dynamic feature allows for real-time exploration of different scenarios, helping users make informed decisions about their academic strategy and goal achievement.  

Weighted Grade Calculation: Formula and Example  

The calculation of a weighted grade involves summing the products of the weights (w) and the corresponding grades (g).  

Weighted Grade = (w₁ × g₁ + w₂ × g₂ + w₃ × g₃ + …) / (g₁ + g₂ + g₃ +...)  

Example 1: Grade type: Percentage  

Determine the weighted grade of a course, in which:  

  • Assignment with a grade (percentage) of 80 and a weight of 30.  
  • Homework with a grade (percentage) of 90 and a weight of 20.  
  • Final exam with a grade (percentage) of 72 and a weight of 50.  

The weighted average grade is determined by the formula:  

Weighted Grade = (w₁ × g₁ + w₂ × g₂ + w₃ × g₃ + …) / (w₁ + w₂ + w₃+...)  

Substituting the values:  

Weighted Grade = (30 × 80 + 20 × 90 + 50 × 72) / (30 + 20 + 50) = 78  

Example 2: Grade type: Letter  

  • Assignment 1 with a grade (letter) of A+ and a weight of 20.  
  • Assignment 2 with a grade (letter) of B and a weight of 20.  
  • Final exam with a grade (letter) of C- and a weight of 60.  

The weighted average grade of the course is calculated by the formula:

Weighted Grade = (w₁ × g₁ + w₂ × g₂ + w₃ × g₃ + …) / (w₁ + w₂ + w₃ +...)  

Weighted Grade = (20 × 4.33 + 20 × 3.00 + 60 × 1.67) / (20 + 20 + 60) = 2.64   

The table below shows how your letter grades convert to a numeric grade (4.0 scale) and percentage grade (% scale):  

Example 3: Grade type: Point  

Consider the following case:  

  • For Assignment 1, the grade is 60 out of 80.  
  • For Assignment 2, the grade is 30 out of 50.  
  • For Homework, the grade is 120 out of 120.  
  • For the Final exam, the grade is 60 out of 100.  

The formula to calculate the weighted average grade is:  

Weighted Grade = sum of real grade / sum of maximum grade  

Weighted Grade = (60 + 30 + 120 + 60) / (80 + 50 + 120 + 100) = 77.14  

Important Role of the Grade Calculator in Academic Path  

The Grade Calculator functions as a flexible tool that aids both educators and students, fostering efficiency and transparency. Knowing the average grade is essential for strategic decision-making in scenarios and setting achievable academic goals.  

Scenario Planning:  

Some Grade Calculators allow users to experiment with different scenarios. For instance, students can input hypothetical scores for future assignments or exams to see how they would impact their final grade. This helps in understanding how adjustments to upcoming assessments may impact the overall class performance.  

Teachers can use a Grade Calculator to streamline the grading process. By inputting scores and weights, the tool can quickly calculate overall grades, saving time and ensuring accuracy.  

Goal Setting:    

Users can set grade goals and determine the scores needed on upcoming assessments to achieve those goals. This application is particularly helpful for students who aim for a specific final course grade. Goal-setting helps students set realistic academic goals and understand the scores needed to achieve them. Knowing their current grade and having the ability to plan for future assessments can reduce stress for students.  

The Grade calculator provides the average score for a specific course. Students can use this result to calculate their GPA, which represents the average score across all their courses. In essence, the output from the Grade calculator acts as the input for the GPA calculator.

Grade Calculator - FAQs  

What grade do i need to pass a college class  .

The grade needed to pass a college class varies depending on the grading system used by the schools, colleges, and academic institutions . In many cases, a passing grade is a D or higher, which is usually equivalent to a numerical grade of 60% or more. However, some programs or courses may require a higher minimum passing grade, so it's important to check your college's policies.  

How do you calculate the percentage grade?  

To calculate a percentage grade, you divide the points earned by the total points possible and then multiply by 100. For example, if you earned 85 points out of a possible 100, your percentage grade would be: (85/100) * 100 = 85%.  

How much will a 0 affect my grade?  

A zero can significantly impact your grade, especially if it's for a major assignment or test. Since a zero has a large weight in the calculation of your average score, it can pull down your overall grade significantly.  

How much will a 71 affect my grade?  

The impact of a 71 on your grade depends on several factors, such as the weight of the assignment or test in the overall course grade and the grading scale used by your instructor. If the 71 is for a major assignment or test and carries a significant weight in the course, it could have a noticeable effect on your overall grade, potentially lowering it. However, if the assignment is one of many and has a lower weight in the course, its impact may be less significant.

How to Calculate Weighted Grade?

To calculate a weighted grade, you need to assign different weights or percentages to each assignment. Such as projects, midterms, homework, and quizzes, and then multiply the grade earned in each assignment by its corresponding weight. Finally, add up these weighted grades and divide them by the sum of weights to obtain an overall weighted grade.

Here's an example:

Suppose there are three categories of assignments:

  • Projects (weight of 35%)
  • Midterms (weight of 40%)
  • Homework (weight of 25%)

A student earns the following grades in each category:

  • Projects - 75%
  • Midterms - 90%
  • Homework - 82%

Weighted grade = (project grade × 35%) + (midterm grade × 40%) + (homework grade × 25%) / 35 + 40 + 25

= (75 × 35) + (90 × 40) + (82 × 25) / 100

= (2625 + 3600 + 2050) / 100

= 8275 / 100

Therefore, the student's overall weighted grade for the course is 82.75% .

How to use Grade Calculator?

Before getting started, ask your teacher, how much each assignment category is worth. Also, you can check it out from the course syllabus. Because it will be needed for the grade calculation.

  • Firstly, select the grade type. Our tool gives you access to enter the grades in three formats. Percentage, Letters, and Points. So, choose the required one of them.

The grade calculator can help you estimate your overall grade based on your component marks . The tool deals with three types of grading systems prevalent in the US – it's a letter grade calculator, a grade percentage calculator, and a point grade calculator.

In the text, you can learn how to use the grading calculator and how to determine an overall grade without it. Find out how to calculate weighted grades, how to calculate grade percentages, and more.

You can use the tool as an unweighted or weighted grade calculator , and set the particular grading scale your teachers use.

🔎 Check our weighted average calculator if you want to learn more about the weighted average.

Prefer watching rather than reading? We made a video for you! Check it out below:

We divided the tool into three parts – a letter grade calculator, a grade percentage calculator, and a point grade calculator. You can enter up to 20 marks (new fields will appear once you fill in the last row displayed).

The weights are, by default, set to 1. Leave them as they are if you want to calculate an unweighted average. If your grades have weights, set them accordingly. If the weights are percentages, enter them in decimal form ( 1 = 100%, 0.5 = 50%, 0.2 = 20% , etc.).

Schools and universities in the United States use different grading scales. You can read more about them using Omni's GPA calculator . You can specify the thresholds used by your teachers in the Advanced mode (click the button below the grading calculator). By default, the calculator uses this common grading scale :

Some schools don't use "+/-". In this case, the most popular grading scale looks like this:

For a quick estimation of the final grade, our final grade calculator should be a valuable tool.

The letter grading system is common in the US. Let's see how to use the letter grade calculator :

If your school uses a different grading scale than the one described in the first paragraph , go to the Advanced mode and set the grading scale.

Set the Grades type to "Letters."

In the first field, choose the grade you got from the first assignment, test, exam, or subject.

If your grades have weights or credits, enter the weight of the first grade. You can enter a natural number, a decimal, or change the unit to a percentage. If the weight is a percentage, you can input its decimal form (e.g., 0.5 for 50%).

If you're calculating the unweighted average (all grades are equally important), ignore the letter grade calculator's weight fields.

Proceed this way with all your marks. New rows will appear as you fill in the last field.

Your overall grade will appear at the bottom of the letter grade calculator.

If you want to clear all the fields and make the calculator grade again, click the circular arrow icon to reload it.

To use the grade percentage calculator :

Set the Grades type to "Percentage".

Type in the percentage result of your first test, task, or subject. Underneath, enter the weight or credits given for the grade. Ignore this field if your teacher doesn't use weights.

Continue to enter the percentage grades of all your assignments, tests, etc., along with their weights. New rows will appear once you fill the last field.

The grade percentage calculator will display the average of your marks. It'll also tell you the equivalent letter grade. The calculator is based on the default grading scale , so change it in Advanced mode if you need to.

To use the point grade calculator :

Set the Grades type to "Points".

Enter how many points you got from the first task, assignment, or subject. Then type in the maximum number of points you could get for the task.

Set the weights (credits) if applicable.

Enter the rest point grades, along with both maximum points and weights.

The point grade calculator will show you how many points you achieved in total and what was the maximum you could have got (your score/max, while ignoring the weights). You'll also see the equivalent percentage and letter.

The formula that lets you calculate weighted grades is:

(g₁ × w₁ + g₂ × w₂ + … + g n × w n ) / (w₁ + w₂ + … + w n ) ,

  • "g" stands for "grade"; and
  • "w" stands for "weight".

This is what the weighted grade calculator uses.

The formula answers the question "how to calculate weighted grades." We could translate it into some instructions :

  • Multiply all your grades by their weights.
  • Sum the numbers from step 1.
  • Sum the weights.
  • Divide the sum from step 2 by the sum from step 3.

The weights tell you how important the grade is. Imagine you got a grade B with a weight of 2 and an A with a weight of 5. It's as if you got two Bs and five As. Let's find the overall grade from these marks.

First, we need to convert letters to numbers . "A" stands for 4, and "B" equals 3. Now that we know this, let's use the formula described above and calculate the weighted average of all grades:

(3 × 2 + 4 × 5)/(2 + 5) = 26/7 ≈ 3.71

We translate the result back to the letter : 3.71 is an "A-".

In the case of percentage grades, we use the same formula as for letter grades.

Example : you're finishing a year and want to calculate your overall grade for a class. You got 67% for an essay worth 15% of the grade, 75% for a midterm exam worth 35%, and 72% for a final worth 50%.

Let's apply the formula. Remember to convert the weights from percentages to decimals . If you need help, our decimal to percent converter may come in handy. The weights add up to 1 (100%), so you can skip the denominator part of the formula.

67% × 0.15 + 75% × 0.35 + 72% × 0.5 = 10.05% + 26.25% + 36% = 72.3% ≈ 72%

Your final grade is 72%, which we may denote as C-.

In the case of point grades, we can convert them to percentages and assign a letter equivalent if needed. We can use the following formula for point grades :

p 1 /p 1,max × w₁ + p 2 /p 2,max × w 2 + … + p n /p n,max × w n ) / (w 1 + w 2 + … + w n ),

  • p – Points acquired on a test;
  • p max – Maximum number of points on a test; and
  • w – Weight of a grade.

To estimate your test grade, you can also check our test grade calculator .

Example : I got 70/100 points on the first test, 46/100 on the second one, and 177/200 on the third one. The first test constitutes 30% of my overall grade, and so does the second one. The third one is worth 40%. Calculate my grade.

Let's substitute our values into the formula :

grade = (70/100 × 30% + 46/100 × 30% + 177/200 × 40%) / (30% + 30% + 40%)

Usually, when we express weights in percentages, they add up to 100% (or just one in decimal notation). In these cases, you can skip the denominator part of the formula (since dividing by one doesn't change the result).

We convert the percentages to decimals :

grade = (70/100 × 0.3 + 46/100 × 0.3 + 177/200 × 0.4) / (0.3 + 0.3 + 0.4) .

We convert the points (grades) to percentages , and the weights add up to 1:

grade = (70% × 0.3 + 46% × 0.3 + 88.5% × 0.4) / 1 .

We add up the numbers and round the result:

grade = 21% + 13.8% + 35.4% = 70.2% ≈ 70% .

We assign a letter :

70% is a C- .

What's a 75 in letter grade?

A 75% in letter grade is equivalent to a C , which is considered a passing grade. Generally, a C is somewhere between 70 and 79 percent.

Some schools use letters with "+/-", meaning that a C- is 70-72 percent , a C is 73-76 percent , and a C+ is between 77 to 79 percent .

How do I calculate my final grade in percentage?

To calculate your final grade in percentage:

Add up the grades you've received on all the assignments, tests, and projects.

Divide this by the total points possible.

Multiply your result by 100 to express it as a percentage.

For instance, suppose your scores are 15/20, 18/20, and 12/20:

The total points you got are: 15 + 18 + 12 = 45

When dividing this by the total possible points of your course ( 60 ), you get: 45 / 60 = 0.75

In percentage terms, your final grade is: 0.75 × 100 = 75% .

In addition, the Final Grade Planning Calculator displays the grade needed on outstanding assignments to reach a target final grade. Also, the Final Grade Calculator determines what a student needs to score on their final exam to reach their target final grade.

Compared to the normal average, a weighted average requires more calculations. When you figure out a weighted average, the many numbers you use are given varying weights or values in relation to one another. This phenomenon occurs in most high-school and college courses, where different assignment types are worth different percentages of the final grade. A course grade calculator makes finding weighted averages quick and accurate.

In addition, many students become concerned near the end of a quarter, semester, or year. They often worry that they will not get a good grade, but they can rely on a Final Grade Planning Calculator to tell them how to perform to reach their desired goal.

Similarly, students often need to achieve a specific score on their final project or exam to get the desired grade. In this case, a Final Grade Calculator lets them know how hard they must work to get where they need to go.

Suppose a grading period is over and all grades are accounted for. In that case, a student can use the Grade Calculator to ensure the teacher made no mathematical errors. In this example, the student enters each assignment, grade, and weight into the calculator.

After clicking "Calculate," the Grade calculator provides a numerical and letter grade.

Average Grade: 87.7 (B+)

Provided there are still grades or categories outstanding, enter the target final grade and the weight percentage weight of the outstanding assignments.

After hitting "Calculate," the Final Grade Planning Calculator will display the current weighted average and the score required on outstanding work to achieve the desired final grade.

  • Average grade: 85.0 (B).
  • A grade of 95.0 is needed for the remaining 30% of tasks to ensure a final grade of 88.

When all grades other than the final exam are accounted for, enter the current weighted average grade, target grade, and final exam weight in the Final Grade Calculator. Click the Calculate button.

  • Your current grade: 79
  • The grade you want: 85
  • Your final is worth: 35%

The Final Grade Calculator will display the final exam grade necessary to attain the desired final grade.

Result You will need a grade of 96.1 or higher on the final.

Weighted averages include numbers with different abilities to skew the average—thus the term "weighted." Unfortunately, many students (and some teachers!) don't understand how to calculate grades using weighted averages because they require more calculations than simple ones.

Suppose you're attempting to figure out your grade in a class where different assignments are worth varying percentages of your final grade. In that case, you might need to determine a weighted average. Whether the sum of your weights equals 1 (or 100%) will affect the method you employ.

It's Pretty Simple When You Have All the Data

To calculate a weighted average where the total weights equal 1, multiply each grade by its corresponding weight and add them all up. Rendered mathematically: g1(w1) + g2(w2) + g3(w3), and so on, where g is each grade and w is the corresponding weight. Of course, most syllabi list weights as percentages, so you will need to convert them into decimals first. For example, 25% equals 0.25; therefore, 100% equals 1.

The math is slightly different when some grades are missing, and the total weights equal less than one. This happens when you use the Final Grade Planning Calculator to determine your current weighted average and the score needed on the outstanding work to get the final grade you want.

Mathematically, you would figure out the weighted average the same way. However, you need to take the sum of each grade (weight) and divide it by the total weight of the known grades (in decimal form).

The formula would be Σgw/Σw where Σgw is the sum of each grade (weight) and Σw is the sum of all weights in decimal form.

The complexity of these calculations makes a weighted grade calculator a lifesaver for students.

Grading is a comparatively recent invention. Since 1785, students at Yale have been receiving the Latin equivalents of the words best (optimi), worse (inferiores), and worst (peiores). So, Yale was the first university in the United States to assign grades.

Before that, American colleges followed the Oxford and Cambridge models, which required frequent attendance at lectures and a weekly dialogue between the student and their proctor, both in person and in writing.

When the proctor or panel of other professors thought the students had shown an appropriate grasp of the subject, the course was declared complete. The faculty gave no grade. A prospective employer could only compare a student's qualifications through reference letters.

Universities experimented with a wide variety of systems during the 19th century. For example, Yale used scales ranging from four to nine points. The professors at Harvard experimented with 20 and 100-point scales before deciding that grouping students into five classes, with the lowest class failing the course, was the best they could do.

To assist professors in evaluating students, William and Mary public research University in the U.S. used the categories: "orderly, accurate, and attentive" or "they have learned little or nothing."

Because of the significant increases in immigration and the emergence of regulations requiring compulsory attendance, schools were overcrowded at the beginning of the 20th century. As a result, teachers and administrators needed an effective, standardized method for testing and grading many pupils. These circumstances naturally led to the nationwide standardization of school grading.

Our calculators use the percentages and letter grades common in the U.S. However, there are many other ways to assess student progress. Here is a quick list of common grading alternatives:

  • A percentage ranging from 0% to 100%.
  • Letter Grades with Variations (A, C+, B-).
  • Standard-Based. Students receive marks relative to specific knowledge in the curriculum.
  • Mastery-Based Grading. Students have the time to master a skill before moving to another.
  • Narrative-Based Grading. Students receive lengthy written feedback about their performance in class.

It may seem that the student grading system has been around forever. However, before the 20th century, the grading systems we now know did not exist.

We still worry about how to determine our grades when each type of assignment has its own "weight." We wonder what we need to get on the final exam to pass.

Our grade calculator can't give you the knowledge to handle every assignment. But he can reassure you by telling you where you are and what results you need to achieve.

    How to calculate percentage of marks?

To find the percentage of marks only basic arithmetics with proportions is required. If it is a single mark, first divide the mark by the maximum possible mark and then multiply by 100 to get the percentage. If there are multiple marks involved, first find their sum total, then proceed as if it is a single mark and divide by the maximum total marks out of which these marks were obtained. Multiply by one hundred at the end to convert to percent. You can do this by hand, following the formulae below, or by using our mark percentage calculator above.

For example, if an exam has a single section and the maximum score is 25, for a student who scored 18 enter 18 in the first input field and 25 in the second, then click "Calculate". If an exam has three sections, or a student is scored on three separate subjects, enter the three obtained scores separated by spaces or commas like so "80 60 90" and then enter the maximum score they could have obtained, e.g. 300 if the score ceiling on each test is 100.

    Marks to percentage formula

In the simplest case we have just a single exam and therefore a single test grade to work with. In this case the calculation to convert marks into percentage is straightforward by following this formula:

Mark Percentage = Scored Mark / Test Maximum x 100

"Test maximum" corresponds to the "Out of ... marks" input field in our test grade percentage calculator.

If an exam is scored in separate test sections, or if you are calculating the percentage from several separate exams, then the following formula is applicable:

Mark Percentage = Sum of Scored Marks / Test(s) Maximum x 100

The sum is calculated in the usual way using simple algebra. Our percentage calculator of marks handles that for you automatically.

    Test marks to percentage - practical examples

First, a simple example with a single test. Let's say a student scored 85 on an exam with a maximum mark of 100. Plugging the numbers into the above formula, we get:

85 / 100 = 0.85 x 100 = 85% so the test percentage is 85%.

Now for a more complicated example of converting a score to percentage where there are two tests or two test sections that are being scored. If a student scored 92 points on the first exam and 88 points on the second one, and the total marks they can get on both tests is 200, what is the percentage that the student scored? To calculate this, we first sum up the two marks and then apply the equation as usual:

(92 + 88) / 200 x 100 = 180 / 200 x 100 = 0.90 x 100 = 90% so the overall percentage mark is 90%.

The table below shows the test grades on a given examination and their corresponding percentages assuming a maximum mark of 200.

All test percentages in the table are computed using this exam percentage calculator.

    How to calculate the average percentage score for an entire class

The above method can be expanded to any number of marks, including calculations for the percentage scored by a whole class of students on a given test material, or even across class subjects which can be useful to educators as a measure of success. For example, with 20 students in a class, enter the 20 marks obtained in the "Scored" calculator field (separate by spaces or commas) and then the maximum possible score (e.g. 20x40 = 800 if each student can get a maximum of 40 points) in the "Out of" field.

What is a weighted grade?

A weighted grade is one in which all the assessments in a course have different degrees of importance, or "weight." For example, a course may involve homework, quizzes, exams, projects, presentations, and more. Typically, exams have a larger weight than quizzes and homework, since exam results are often considered to be the most important assessment in a course.

As an example, a course may have exams that account for 50% of the final grade, while quizzes make up 30%, and homework makes up 20%. This means that a 95 on a homework assignment and a 95 on an exam do not carry the same weight; a 95 on an exam has more of an effect on the final grade than a 95 on a homework assignment because it has a larger weight.

How weighted grade is calculated?

There are different formulas for calculating weighted grades depending on the information available. This calculator assumes a total weight of 100 and uses the following formula to calculate the weighted grade, where w i is the weight of the respective grade g i :

For example, given the following grades and respective weights,

the weighted grade is computed as follows:

92.75 is the current weighted grade based on the grades achieved thus far. Since the calculator assumes a total weight of 100, there are still remaining grades that together have a weight of 80. Once the values of the remaining grades and their weights are known, the final weighted grade can be computed in the same manner as above. In cases where the assessments (exams, quizzes, homework, etc.) have weights in terms of percentages, the weighted grade can be computed by finding the average grade attained for each assessment, then multiplying by their respective weights. Given that w i is the weight in percentage form of the average grade g i achieved in each respective assessment: Weighted grade = w 1 g 1 + w 2 g 2 + w 3 g 3 + ...+ w n g n For example, given that a student's homework is worth 20%, quizzes are worth 30%, and exams are worth 50%, if a student achieved an average grade of 85 on all their homework assignments, an average of an 87 on all their quizzes, and an average of 83 on all their exams, their weighted grade is calculated as follows:

(85)(0.2) + (87)(0.3) + (83)(0.5) = 84.6

Thus, their weighted grade is an 84.6.

What are the different grade formats?

The calculator uses three different grade formats: percentage, letter, and point value.

Percentages:

Percentage grades are grades expressed in percentage form. They range from 0-100%, and are calculated by dividing the score earned by the student by the total possible score on the assessment. For example, consider a multiple-choice exam in which all the questions are worth the same number of points. To calculate a student's percentage grade, divide the number of questions the student answered correctly by the total number of questions, then multiply by 100. This is the student's percentage grade. For example, if a student answered 39/50 questions correctly on an exam, their percentage grade is:

Percentage grades are related to letter grades through a grading scale. Grading scales vary throughout institutions, so an A at one school may not correspond to the same percentages as another. Refer to the table below in the "Letter grades" section to see how percentages and letter grades are related in one of the more commonly used grading scales in the US.

Letter grades:

Letter grades range from A-F in the US grading system, where an A is the highest achievable grade, and an F is a failing grade. However, even within the US system, there are variations in what each letter represents, as well as in the letters used in the system. For example, there are institutions that use grades such as A+, B-, C+, etc., while there are others that do not make use of plus and minus grades, and only use the letters A, B, C, D, and F. Also, depending on the institution, a D, or even a C, might constitute a failing grade for the course.

Letter grades correspond to a specific range of percentage values. The range of values assigned to a given letter differ based on the grading scale, but are generally pretty similar. The following table shows a commonly used grading scale, and the corresponding letter and percentage grades.

How to Calculate Grades Based on Percentages (With Calculator!)

Determine grading policy, grade calculator, calculate category averages, converted weighted grade percentages, calculate averages, determine total grade, how to handle a weighted grading system, how to handle point systems to determine your total score, how to determine how much you need to score on your final exam to maintain your grade.

Many high school teachers and college professors weigh homework, quizzes and test grades differently depending on the difficulty and significance of the assignment. Big tests (like a midterm exam or final exam) and quizzes generally account for most of the total grade, because they encompass more of the subject material.

The letter grades you receive in the gradebook after all of your individual assignments, tests, and quizzes have been graded make up your grade point average (gpa). Typically, students want to keep their gpa as high as possible. Whether you are on the verge of failing a class, or you have pretty good grades and just want to know how your grades add up, you can calculate your grades with a few simple formulas.

1. establish your professor's grading policy for how each category is weighted.

  • The professor may announce this early on in the class for clarity. If they do not, you can also check with the ​ course syllabus ​ or refer to the school policy.
  • Asking directly may be best because of professor preferences in their weighted grading system that may not be updated in online materials.

For example

The professor may weigh 35 percent of the final grade to quizzes, 20 percent to homework and 45 percent to tests.

Below we provide a grade calculator as an alternative to performing the grade calculations explained in the article.

2. Calculate the average of each category by adding up all of your scores for each category and divide by the number of assignments in that category.

If you have five tests with the scores of 90, 85, 100, 75 and 91, the accumulated point total for all your test would be 441. Divide the total by five for your test average of 88.2 percent.

3. Convert the weighted grade percentages to decimal value by dividing the percentage by 100.

If tests are weighted 45 percent of the total grade, the decimal would be 0.45 (45 / 100 = 0.45).

Repeat this step for each weighted section (homework, quizzes, tests, etc.).

4. Multiply the average for each category by the weight, in decimal, of each category to calculate the total points out of 100.

If your test average is 88.2 percent and is weighted 45 percent, the points for your overall grade out of 100 would be 39.69 (which is 88.2 x 0.45). Repeat this step for your other subject categories.

While most professors will maintain the final grade given, speaking with the professor can result in updating the grade through additional projects or corrections.

Additionally, if a student is not happy with the course grade, some colleges have policies allowing classes to be repeated and then averaged, which can also raise a course grade as well as your overall gpa.

5. Add the results for each category from Step 4 to find out your total grade out of 100 points.

If you calculated a 39.69 for test, 34 for quizzes and 18.5 for homework, your total grade would be 92.19 percent.

At many colleges using a four-point scale, an A requiring a total grade of 90 with a B letter grade falling in the 80 percent range.

A C grade ranges between 70 and 80 percent with a D ranging from 60 to 70 percent. Anything below a 60 percent would be considered a failing grade, or F.

These grade ranges do vary by school and professor, and they are general estimates with some colleges starting an A at 92 percent, a B at 83 percent and so on.

A weighted score is the key to understanding where your professor wants you to focus. Look especially for attendance or term papers. If your syllabus mentions extra credit, do the extra credit work because it gives you a buffer going into your final exam.

The key is to start from the max total score and follow the breakdown from tests and quizzes to homework and attendance.

As an example, a language course has a quiz every class that is worth 20 points. If you have 30 quizzes or two per week, the total quiz points is 600. If the total number of points is 1,000 and 600 or 60% (600 / 1000) comes from quizzes, you should spend extra time ensuring you maximize your quiz score.

On the other hand, point values from quizzes are often weighted lower than your midterm and final grades – often, because your instructor wants to grade you on your complete understanding of the material rather than recalling by rote something from the textbook.

Your overall grade will often be determined by your final exam. Because your class is almost complete, you should take your syllabus and your scores and be able to calculate your current class grade.

For example, your current grade may be a B+ because out of 800 possible points, you have 704 points or 88% (704 / 800). If your final exam is worth 200 points, then your total points is 1,000 and you will need 186 on your final exam for an A- (900 / 1000 is 90%) and a perfect score on your final exam worth 200 points, will still keep you at an A- for your overall grade. Why? Because your final exam was only 20% of your total grade.

How to calculate weighted grade average?

  • First multiple the grade received by the weight of the assignment. Repeat this for each completed assignment.
  • Then add each of the calculated values from step 1 together.
  • Next add the weight of all the completed assignments together.
  • Finally, divide the calculated value from step 2 above by the value calculated from step 3. This gives you the weighted grade average.

Weighted Grade Formula

Weighted Grade = (w 1 x g 1 + w 2 x g 2 + w 3 x g 3 + …) / (w 1 + w 2 + w 3 + …)

Example Calculation

Here is an example. Let's say you received a 90% on your first assignment and it was worth 10% of the class grade. Then let's assume you took a test and received an 80% on it. The test was worth 20% of your grade.

To calculate your average grade, follow these steps:

  • Multiple each grade by its weight. In this example, you received a 90% on the first assignment and it was worth 10%. So multiply 90 x 10 = 900. You also received an 80% on the test and it was worth 20% of the class grade. So multiply 80 x 20 = 1600.
  • Add the calculated values from step 1 together. We now have 900 + 1600 = 2500.
  • Add the weight of all the completed assignments together. To do this, add 10% for the first assignment and 20% for the second assignment. That gives us 10 + 20 = 30.
  • Finally, divide the value from step 2 by the value from step 3. That gives us 2500 / 30 = 83.33. Therefore our weighted grade average is 83.33%.
