Cumulative GPA Calculator

See how your new semester affects your overall GPA — instantly.

Quick Answer

Cumulative GPA is calculated by combining all grade points across every semester and dividing by total credits earned — not by averaging semester GPAs. Two semesters with a 3.0 and 3.8 GPA (15 credits each) produce a cumulative GPA of 3.40. More credits on record means a harder GPA to move.

What Is Cumulative GPA?

Your cumulative GPA is the overall average of all grades you've earned across every semester, weighted by credit hours. Unlike a semester GPA — which only reflects one term — your cumulative GPA represents your entire academic history at an institution.

It appears on your official transcript and is the number employers, graduate schools, and scholarship committees reference when evaluating your academic record.

The Cumulative GPA Formula

Formula: New Cumulative GPA = (Current GPA × Current Credits + New Semester GPA × New Credits) ÷ (Current Credits + New Credits)

Example: You have a 3.20 GPA with 45 credits. You just finished a semester with a 3.60 GPA earning 15 credits. (3.20 × 45 + 3.60 × 15) ÷ (45 + 15) = (144 + 54) ÷ 60 = 3.30.

How One Semester Affects Your Cumulative GPA

The impact of a single semester decreases as you accumulate more credits:
