How to Calculate GPA
A simple, step-by-step guide to calculating GPA on any scale — plus free calculators that do it for you.
Step 1 — Convert grades to points
| Letter | 4.0 Scale | Weighted (AP/Honors) |
|---|---|---|
| A | 4.0 | 5.0 |
| B | 3.0 | 4.0 |
| C | 2.0 | 3.0 |
| D | 1.0 | 2.0 |
| F | 0.0 | 0.0 |
Step 2 — Multiply by credits
For each course: grade points × course credits = quality points. Add all quality points, then divide by total credits attempted. That's your GPA.
Example: A (3 cr) + B (4 cr) + A (2 cr) → (4×3)+(3×4)+(4×2) = 12+12+8 = 32 ÷ 9 credits = 3.56 GPA.
Step 3 — CGPA (cumulative)
CGPA = total quality points across all semesters ÷ total credits. Or simply average your semester GPAs weighted by credits. Use our CGPA Calculator for instant conversion.
