What is GPA?

In real life, we heard this term many times when we are in school or college. So, let's understand it in-depth.

GPA stands for "Grade Point Average". It is a standard way of measuring achievements in school or college.

In other words, it is an average number that shows what you have scored in your classes throughout the term, semester, and year.

Mostly, the grade point average is calculated on a 4.0 scale. So, it may count in the range from 0.0 to 4.0.

0.0 defines the lowest score, and 4.0 defines the highest score. In addition, this type of GPA is known as an "Unweighted GPA".

But some academics consider Advanced Placement(AP) or Honors classes for extra points. So, they consider 5.0 as the highest score and it is known as a "Weighted GPA".

Also, check out this good educational tool: Mean Calculator. It will surely be helpful somewhere in your study.

Letter Grade to GPA Scale Table

In the following table, the letter grades are converted into numerical values. Also, we can call it "Grade Points". We need this table when we are calculating the GPA manually. It will help us to find the Grade Points from Letter Grades. Also, you will get more ideas about this table when we take some examples.

But you don't need to remember this table all the time. Our GPA calculator will automatically take the grade point values from the table. Therefore, you don't need to enter it manually.

Letter Grade Percent Grade Grade Point
A+ 97-100 4.33
A 93-96 4.00
A- 90–92 3.67
B+ 87–89 3.33
B 83–86 3.00
B- 80–82 2.67
C+ 77–79 2.33
C 73-76 2.00
C- 70-72 1.67
D+ 67-69 1.33
D 63-66 1.00
D- 60-62 0.67
WF/F Below 60 0

Most of the universities and high schools are following the above conversion scale. But some academics uses 2 decimal digits (i.e. .67, .33, ...) for more accurate results. This difference is minor. That's why it will not affect the final resultant value. Also, many schools and universities do not consider the "A+" grade. They use "A" as the highest one.

Note: We recommend you check the GPA scale table from your university's official website before doing the calculation.

How to Calculate GPA?

If you want to know how to calculate GPA manually, then this section is for you. Here we will discuss some mathematics formulas and its calculation with some examples.

Grade Point Average Formula

Firstly, let's know the GPA calculation formula in words.

The GPA is equal to the sum-up of all the credit hours(C) multiply by grade points(G) and then divide by the sum of credit hours.
(C1 × G1) + (C2 × G2) + ... + (Cn × Gn)
(C1 + C2 + ... + Cn)

C = Credit Hours (The hours assigned to a particular course)
G = Grade Points (You can find it from the GPA Table)

Basically, there are three operations that we need to perform respectively.

  • Multiplication
  • Addition
  • Division

Now follow the step-by-step instructions to calculate the GPA.

  1. Firstly, find the grade points from GPA Table.
  2. Multiply each credit hour and grade point and then sum up all the resultant values.
  3. After that, find the sum of all the credit hours.
  4. Lastly, divide step 3's value with step 2's value.

Finally, you will get the final Grade Point Average.

Now let's take some examples to understand the above all points step by step.

Example 1:

Suppose John completed 3 courses: Maths with "A" grade, Chemistry with "B+" grade, and Physics with "B" grade. Find out the grade point average.

Course Grade Credit Hours Grade Points
Maths A 3 3 × 4 = 12
Chemistry B+ 4 4 × 3.33 = 13.32
Physics B 2 2 × 3 = 6
Total - 9 31.32
GPA (31.32 / 9) = 3.48

Now let's figure out how it is calculated.

Firstly, we will use GPA Scale Table to convert letter grades into grade points and then apply them to the formula.

You can see the full calculation below:

GPA Calculation Example

Example 2:

Let's take 3 courses: Computer Lab(A+), Algebra(B-), and English(C). Find out Grade Point Average.

Course Grade Credit Grade Points
Computer Lab A+ 1 1 × 4.33 = 4.33
Algebra B- 3 3 × 2.67 = 8.01
English C 3 3 × 2 = 6
Total - 7 18.34
GPA (18.34 / 7) = 2.62

Let's figure out the GPA using the formula.

Cumulative GPA Example

Finally, we get GPA = 2.62.

Now we are clear with how to calculate GPA. Just perform simple multiplication, addition, and division one by one. That's it.

But you don't need to do this manual calculation all the time. Because it's a very lengthy process. Even more, it will take more time when there are more than 7 or 8 courses. Instead of doing this, use our GPA calculator to save your time and effort. Also, our tool will give you 100% accurate output. Because it is working on pre-defined algorithms.

How to use the College GPA Calculator?

It's very simple to use the tool. Just follow the steps below to get started.

1. Enter course name (Optional)

Firstly, enter the course name (i.e. Maths, Physics, Chemistry, etc...) in the first column. It's an optional step. But don't skip it. We recommend you enter the course name from the beginning. Because it will help you to differentiate the exam grades and credit hours.

Enter Course Name
2. Choose Letter Grade

Next step is to select the letter grades from A+ to NP. It's a second column where you can find these selection options.

Choose Letter Grade
3. Enter Credit Hours

It is the most important step. In this step, you have to enter the credit hours that you have earned from each course.

Let's take an example to understand it.

If you earned B+ for 4 credit hour course, then you need to enter 4 in the third column box.

Enter Credit Hours

If you are calculating GPA for less than 4 courses. Then it's Ok! But if you want to add more courses then you can use the "+ Add Course" button to add more rows. Also, you can add as many courses as you want. There is no limit on that.

Add Courses

Even more, there is an optional field to enter your previous semester's cumulative GPA and Credits. You can enter these values if you want to find an average of an overall (Previous + Current) semester GPA.

To convert percentage into a 4.0 GPA, you can use the below formula.

GPA = ( x / 20 ) - 1

Where, x = Percentage of score

Let's take an example.


A student gets 75% of the score in the History course in his final exam. Convert the percentage score into GPA.

Here, x = 75%

GPA = ( x / 20 ) - 1 = ( 75 / 20 ) - 1 = 3.75 - 1 = 2.75

Hence, we can say that the student got 2.75 GPA in his final exam.

You can add an infinite number of courses to the calculator. There is no specific limit for that.

You can find your college grades using the grade calculator and final grade calculator.
