Cumulative GPA Calculator
Merge this term’s GPA into your running GPA to see your new cumulative average and how much it moved.
How it works
new GPA = (current GPA × credits + term GPA × term credits) ÷ (credits + term credits)
A cumulative GPA is a credit-weighted average, so merging a term means adding its grade points (GPA × credits) to your existing grade points and dividing by the combined credits. Early in college one term swings the number a lot; by senior year the accumulated credits act like an anchor and even a perfect term barely moves it.
Worked example
A 3.40 GPA over 60 credits holds 204 grade points; a 3.80 term over 15 credits adds 57 more. New GPA = (204 + 57) ÷ 75 = 261 ÷ 75 = 3.48 — up 0.08.
Frequently asked questions
Can I raise a 3.0 to a 3.5 in my last year?
Run the numbers: with 90 credits at 3.0 and 30 credits remaining, even straight 4.0s only reach (270 + 120) ÷ 120 = 3.25. The later you start, the smaller the reachable range — this calculator shows exactly what a target requires.
How do retaken courses affect cumulative GPA?
Policies differ: some schools replace the old grade entirely, others average both attempts, and transfer credits often carry no grade points at all. Use whichever grade your registrar actually counts.
Does this work for high school weighted GPAs?
Yes — the weighted-average math is the same on a 5.0 scale. Just enter GPAs consistently on one scale; mixing weighted and unweighted numbers gives a meaningless blend.
