Your cumulative GPA combines every term so far into one credit-weighted average. If you know your current GPA, the credits behind it, and this term’s GPA and credits, you can calculate where you’ll land.
The cumulative formula
Cumulative GPA = (previous GPA × previous credits + current GPA × current credits) ÷ total credits
The credits act as the weight, so the GPA with more credits behind it pulls the combined number harder.
Worked example
Suppose you carried a 3.5 GPA over 24 credits, and this term you earned a 2.9 across 15 credits:
(3.5 × 24 + 2.9 × 15) ÷ 39 = 127.5 ÷ 39 = 3.27
Your cumulative GPA after both periods is 3.27.
What moves the number
- Credit-heavy history: with 90+ credits behind you, one term moves the cumulative by a few hundredths at most.
- Early on: your first terms swing the cumulative much more — good grades early build a durable base.
- Scale consistency: combine GPAs only within one grading scale, or the weighting loses meaning.
