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

Letter4.0 ScaleWeighted (AP/Honors)
A4.05.0
B3.04.0
C2.03.0
D1.02.0
F0.00.0

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.
