Calculate GPA, course grades and grade percentages with credits.

What is a GPA calculator?

A GPA calculator converts course grades into grade points, multiplies those points by course credits or hours, and divides the total by the number of credits. This helps students estimate academic performance across one term, semester or full programme.

For international grading systems, the calculator can be used as an educational guide by comparing local marks with a common U.S. grading structure. Official conversions may be different, so always check the requirements of your school, university, scholarship provider or admissions office.

How is GPA calculated?

1. Convert each grade to points. For example, A may equal 4.0, B may equal 3.0 and C may equal 2.0 on a standard U.S. scale.
2. Multiply by credits. A 3-credit A course creates 12.0 quality points because 3 × 4.0 = 12.0.
3. Add all quality points. Total the points from every class or module.
4. Divide by total credits. Cumulative GPA = total quality points ÷ total credits.

GPA calculation example

Imagine a student has three classes: 3 credits with an A, 3 credits with a B and 2 credits with a B. The total quality points are 12.0 + 9.0 + 6.0 = 27.0. The total credits are 8. The GPA is 27.0 ÷ 8 = 3.38.
