What is GPA on a 4.0 scale?

GPA (Grade Point Average) is a numerical representation of your academic performance. The 4.0 scale is the most common system, where:

A = 4.0
B = 3.0
C = 2.0
D = 1.0
F = 0.0

Your GPA is calculated by multiplying each grade by the number of credit hours for that course, summing these values, and dividing by the total number of credit hours attempted.

How to calculate GPA on a 4.0 scale

To calculate your GPA:

Convert each letter grade to its corresponding grade point value
Multiply each grade point by the number of credit hours for that course
Sum all the quality points (grade points × credit hours)
Sum all the credit hours
Divide the total quality points by the total credit hours

GPA Formula

GPA = (Σ (Grade Point × Credit Hours)) / (Σ Credit Hours)

Use our interactive calculator below to perform these calculations quickly and accurately.

Example calculation

Let's calculate the GPA for a student with these grades:

Course	Grade	Credit Hours
Mathematics	A	4
English	B	3
History	C	3

Calculation steps:

Mathematics: 4.0 × 4 = 16 quality points
English: 3.0 × 3 = 9 quality points
History: 2.0 × 3 = 6 quality points
Total quality points = 16 + 9 + 6 = 31
Total credit hours = 4 + 3 + 3 = 10
GPA = 31 / 10 = 3.1

The student's GPA is 3.1 on a 4.0 scale.

Interpreting your GPA

GPA ranges on a 4.0 scale:

4.0 = Perfect academic performance
3.5-3.9 = Excellent performance
3.0-3.4 = Good performance
2.0-2.9 = Average performance
Below 2.0 = Below average performance

Note

GPA is just one measure of academic performance. Consider other factors like participation, projects, and extracurricular activities when evaluating your overall performance.
