Even more, in this article, we will learn about the GPA scale table, how to calculate GPA, and how to use the calculator. So, stay tuned and keep reading till the end.

What is GPA?

First of all, let's discuss some basic information regarding the GPA.

In real life, we heard this term many times when we are in school or college. Also, the admission and graduation process totally depends on the GPA marks. A good GPA score will help you to get admission to best schools or colleges. Now, let's understand the term deeply.

GPA stands for "Grade Point Average". It is a standard way of measuring achievements in academics. In other words, it is an average number that shows what you have scored in your classes throughout the term, semester, and year.

Mostly, 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) classes for extra points. So, they consider 5.0 as the highest score and it is known as a "Weighted GPA". In short, a weighted GPA considers the extra points whereas an unweighted GPA doesn't.

Letter Grade to GPA Scale Table

In this table, the letter grades are converted into numerical values. Also, we can call it "Grade Points". You need this table when you are calculating the GPA manually. It will help you to find the "Grade Points" from "Letter Grades". Also, we 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 college GPA calculator will automatically take its values from the table. So, no need to enter it manually.

Letter Grade Grade Point
A+ 4.33
A 4.00
A- 3.67
B+ 3.33
B 3.00
B- 2.67
C+ 2.33
C 2.00
C- 1.67
D+ 1.33
D 1.00
D- 0.67
WF/F 0

Most of the universities and high schools are following this GPA 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 is not affecting 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 to check the GPA scale table from your university's official website before doing the GPA calculation.

How to Calculate GPA?

If you want to learn how to calculate GPA manually, then this is the right section for you. Here we will show you the mathematics formula and its calculation with some examples.

But before we start, let's know the formula in words first.

The GPA is equal to the sum up all the credit hours(C) multiply by grade points(G) and then divide by the sum of credit hours.

Confusing Right? Don't worry. All confusions will be clear from the following formula.

(C1 x G1) + (C2 x G2) + ... + (Cn x Gn)
(C1 + C2 + C3 + ... + Cn)

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

  1. First of all, find the grade points from GPA Table.
  2. Then multiply each credit hours 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.

At last, you will get a final Grade Point Average.

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

Example 1

Suppose a student 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 Grade Points
Maths A 3 3 x 4 = 12
Chemistry B+ 4 4 x 3.33 = 13.32
Physics B 2 2 x 3 = 6
Total - 9 31.32
GPA (31.32 / 9) = 3.48

Now let's figure out how it is calculated?

Here firstly, we took the GPA Table to convert letter grades into grade points and then apply the formula.

GPA Calculator Example

Example 2

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

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

Let's figure out the calculation using formula.

Cumulative GPA Example

Finally, we get GPA = 2.62.

So, now you are clear about How to Calculate GPA. You just need to 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 7-8 courses. Instead of doing this, use our GPA calculator to save your time and effort. Also, there is no chance for the wrong output. Because our tool is working on pre-defined algorithms. So, it gives you 100% accurate results.

How to use College GPA Calculator?

For better understanding, we have divided the process into 4 steps.

  1. Enter course name (Optional)
  2. Select/Choose Letter Grade
  3. Enter Credit Hours
  4. Calculate GPA

Now let's understand above all the steps one by one.

1. Enter course name (Optional)

Firstly, enter the course name in the first column. Such as Maths, Physics, Chemistry, etc. It's an optional step. But don't skip it. We recommend you to enter the course name from the beginning. Because it will help you to differentiate the exam grades and credit hours. Also, it will reduce the wrong input possibility.

Enter Courses

2. Select/Choose Letter Grade

In college GPA calculator, there is an option to select the letter grade. It's a second column where you can find these selection options.

But before entering the values, get your grade report from your school or college. However, if you don't know your confirm grades, then you can choose the estimated grade. It can range from A+(4.33 Scale) to F(0.0 Scale).

Add 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 input box.

Enter Credit Hours

Enter all the grades and credit hours as per your need. In addition, your final GPA will be calculated for all the courses and grades that you have entered.

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 "+ 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

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

4. Calculate GPA

Lastly, you can press the "Calculate" button to start the calculation process. As a result, you will get the grade point average, total credit hours, and full calculation at the bottom of the calculator. Also, you can use "Reset" button for refresh the calculator.

Calculate GPA using College GPA Calculator


Use this college GPA calculator to track your school or college results and reach your goals. ALso, take the feedback regularly using our tool. It will let you know how many improvements do you need in your study management.


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

GPA = ( x/20 ) - 1

Where, x = Percentage of score

Let's take one example to get more idea.


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

Here, x = 75%

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

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

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

You can use college grade calculator to calculate your study grades.
