Cumulative GPA Calculator
Your GPA has inertia — every semester moves it less. Enter where you stand, add this term's grades, and see exactly where you'll land (and by how much you moved).

The formula
New GPA = (current GPA × credits done + Σ new grade points) ÷ (credits done + new credits)
The honest physics of GPA
- Early semesters are leverage: the fewer credits behind you, the more each grade moves the needle. A strong first year is worth more than a heroic last one.
- The arrow tells the story: ▲ 0.08 after a good term is real progress for a junior — don't compare your delta to a freshman's.
- Planning mode: set the grades you're aiming for and see the projected GPA before the semester even starts — then our Grade Calculator tells you what each final requires.
Frequently asked questions
How is cumulative GPA calculated?
Total grade points across all semesters divided by total credits. This calculator does it incrementally: (current GPA × credits completed + this semester's points) ÷ (credits completed + this semester's credits).
Why does my GPA move less each semester?
Inertia: with 90 credits behind you, one semester of 15 credits is only 1/7 of the weight. That's why the arrow (▲/▼) matters — freshmen can move 0.5 in a term, seniors fight for 0.05. Start caring early.
What GPA do I need this semester to reach my goal?
Play with the grades in the semester rows until the new cumulative hits your target — you'll instantly see whether the goal is achievable with your credit load or needs more than one term.
Do retaken courses count?
Depends on school policy: some replace the old grade (big GPA lever), others average both attempts. Check your registrar — the difference is significant.
