How to Calculate GPA (4.0 Scale)

GPA (Grade Point Average) on the standard US 4.0 scale is the credit-weighted average of the grade points earned in each course, where letter grades map to point values from 4.0 (A) down to 0.0 (F). Courses with more credit hours count more heavily toward your overall GPA.

Add every course you're calculating for with its credit hours and the letter grade received, using the standard scale: 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.

Example

A student takes a 3-credit course with an A (4.0), a 4-credit course with a B+ (3.3), and a 3-credit course with an A- (3.7). GPA = (3×4.0 + 4×3.3 + 3×3.7) ÷ (3+4+3) = 35.3 ÷ 10 = 3.53.

Common Use Cases

FAQs

Does this handle plus/minus grades like A- and B+?

Yes — the calculator uses the standard plus/minus 4.0 scale (A- = 3.7, B+ = 3.3, and so on) used by most US colleges and high schools. Some institutions round or omit plus/minus grades, so double-check your school's exact scale if it differs.

What about weighted GPA for AP or honors classes?

This calculator computes standard unweighted GPA. Weighted GPA adds extra points (commonly 0.5 or 1.0) for AP, IB, or honors courses — check your school's specific weighting policy and add those points to the grade before entering it if you need a weighted figure.

Do pass/fail or audited courses count toward GPA?

Typically no — pass/fail and audited courses are usually excluded from GPA calculations entirely at most institutions, so leave them out of this calculator unless your school explicitly includes them.
