Cumulative GPA Calculator
Combine your prior GPA with this semester to get your new cumulative GPA.
Across 75 total credit hours.
To calculate your cumulative GPA, take a credit-weighted average of every term: (prior GPA × prior credits + term GPA × term credits) ÷ (prior + term credits). With a 3.2 GPA over 60 credits and a 3.8 term worth 15 credits, that is (192 + 57) ÷ 75 = 3.32.
How cumulative GPA works
Your cumulative GPA is the credit-weighted average across every term you have completed. The key insight is inertia: the more credits already behind you, the less any single new semester can move the total. Early on, one strong term swings it a lot; by your final year it barely budges.

Worked example
Prior GPA 3.2 over 60 credits, then a 3.8 semester worth 15 credits.
- 1 Quality points so far. 3.2 × 60 = 192 points from prior terms.
- 2 Add this term’s points. 3.8 × 15 = 57 → 192 + 57 = 249 total quality points.
- 3 Divide by total credits. 249 ÷ (60 + 15) = 249 ÷ 75 = 3.32 cumulative GPA.
Reading the result
“My great semester barely moved it.” That’s the weight of history — with 60 prior credits, a single 15-credit term is only a fifth of the average.
Projecting a goal. Try different term-GPA values to see what you’d need this semester to reach a target cumulative. Work out a single term’s number first with the Semester GPA calculator, then feed it in here. Big jumps get harder the further you are into a degree.
Recovering from a low start. Early low grades are the easiest to dilute — consistent strong terms pull the average up fastest before credits pile up.
