How the GPA Calculator Works

The calculator uses the standard US credit-hour weighted formula. Each letter grade is converted to a grade point value (A=4.0, B=3.0, C=2.0, D=1.0, F=0.0 — with plus/minus variants), then multiplied by the course's credit hours. Dividing the sum of all quality points by the total credit hours gives your GPA.

Formula

GPA = Σ(Grade Points × Credit Hours) ÷ Σ(Credit Hours)

Example

English — A (4.0) × 3 credits = 12.0 quality points

Math — B+ (3.3) × 4 credits = 13.2 quality points

History — B (3.0) × 3 credits = 9.0 quality points

Total: 34.2 pts ÷ 10 credits = 3.42 GPA

The 4.0 GPA Scale

Every US letter grade maps to a numeric grade point value. Plus and minus modifiers shift the value by ±0.3 (or ±0.33 at some schools). This table shows all standard values.

Frequently Asked Questions

What is a GPA calculator?
A GPA calculator is a free online tool that converts letter grades to grade points, weights them by credit hours, and computes your Grade Point Average on the 4.0 scale. Enter your courses and grades — the result appears instantly.
How does the GPA calculator work?
The calculator multiplies each course's grade points by its credit hours to produce quality points. It sums all quality points and divides by total credit hours. For example: English A (4.0 × 3 cr = 12 pts) + Math B (3.0 × 3 cr = 9 pts) = 21 pts ÷ 6 credits = 3.50 GPA.
What grades does the 4.0 scale use?
A=4.0, A-=3.7, B+=3.3, B=3.0, B-=2.7, C+=2.3, C=2.0, C-=1.7, D+=1.3, D=1.0, D-=0.7, F=0.0. A+=4.0 at most schools (some use 4.3). This scale is standard across US high schools and colleges.
Can I use this for both high school and college?
Yes. The standard 4.0 GPA scale is used by virtually all US high schools and colleges. The same formula applies — enter your credit hours (or use 1 for each course if all are equal weight) and letter grades.
What if my courses don't have credit hours?
Set every course to 1 credit hour. When all credits are equal, the calculator returns a simple unweighted average of your grade points — equivalent to adding all grade points and dividing by the number of courses.
What is a good GPA?
3.0 (B average) is generally considered good standing. A 3.5+ is competitive for selective colleges and graduate school applications. The national college GPA average is approximately 3.1 according to the National Center for Education Statistics.
