Standard US 4.0 scale. Weighted mode adds +0.5 for Honors and +1.0 for AP/IB courses (max 5.0). Results are estimates — your school calculates the official GPA.
A GPA (Grade Point Average) is the average of your course grades converted to a 4.0 scale. To calculate your GPA, multiply each course’s grade points by its credit hours, add the totals, and divide by total credit hours.
Use the free calculator above — enter your courses, credits, and grades to get your semester GPA instantly, then project your cumulative GPA. No signup, no fees, completely private.

GPA Formula
GPA = Total Quality Points ÷ Total Credit Hours. Quality Points = Grade Points × Credit Hours. On the standard US 4.0 scale, an A is 4.0, a B is 3.0, a C is 2.0, a D is 1.0, and an F is 0.0.
Worked example: A student takes 5 courses:
| Course | Grade | Points | Credits | Quality Points |
|---|---|---|---|---|
| Math | A | 4.0 | 3 | 12.0 |
| English | B+ | 3.3 | 3 | 9.9 |
| History | A− | 3.7 | 4 | 14.8 |
| Science | B | 3.0 | 4 | 12.0 |
| Art | A | 4.0 | 2 | 8.0 |
Total Quality Points = 56.7 · Total Credits = 16 · GPA = 56.7 ÷ 16 = 3.54
03
Semester vs Cumulative GPA
Semester GPA covers one term only. Cumulative GPA is the weighted average across all terms, weighted by credit hours — not a simple average of semester GPAs.
Why simple averaging is wrong: If you earned 3.0 over 12 credits and 4.0 over 18 credits, the simple average is 3.5. The real cumulative GPA is (3.0×12 + 4.0×18) ÷ 30 = (36 + 72) ÷ 30 = 3.60. Credit hours matter — use the Cumulative tab above for the correct math.
04
Weighted vs Unweighted GPA
Unweighted GPA uses the standard 4.0 scale (max 4.0). Weighted GPA adds extra points for harder courses — typically +0.5 for Honors and +1.0 for AP/IB — so it can reach 5.0.
| Course | Grade | Unweighted | Weighted |
|---|---|---|---|
| AP Math (AP) | A | 4.0 | 5.0 |
| English Honors | B+ | 3.3 | 3.8 |
| History (Regular) | A− | 3.7 | 3.7 |
| Biology (Regular) | B | 3.0 | 3.0 |
US high schools commonly report weighted GPAs; most schools recalculate on an unweighted 4.0 scale during admissions.
