A cumulative GPA is not the average of your term GPAs. It is the average of every graded credit you have taken, which means each term counts in proportion to how many credits it carried. A strong twelve-credit term moves the cumulative figure more than a strong six-credit one, and both move it less as your total credit count grows.
The mechanics are straightforward once you think in quality points. Multiply your prior GPA by your prior credits to recover the quality points already banked, do the same for the new term, add both, then divide by the combined credits. This calculator does that and also reports what the following term would have to average to reach a target.
The most important consequence is inertia. Early in a degree a single term swings the cumulative GPA sharply; by the final year the same term barely registers. That asymmetry is why recovering from a bad first year takes far more than one good term.
The formula
Prior GPA- Your cumulative GPA before this term
Prior credits- Graded credits already completed
Term GPA- The GPA earned this term alone
Term credits- Graded credits taken this term
How to use this calculator
- Enter the cumulative GPA and credit total shown on your transcript.
- Enter this term’s GPA and the credits it carried.
- Set a target GPA to see what the next term must average.
- The gauge shows the new cumulative GPA; the change appears below.
Worked examples
A good term after a moderate start
A prior 3.20 over 45 credits carries 144 quality points. A 3.70 term over 15 credits adds 55.5 more, giving 3.325 across 60 credits — a rise of 0.125.
The same term three years later
Apply that identical 3.70 term to a prior 3.20 over 105 credits and the cumulative figure only reaches 3.263, a rise of 0.062. Nothing changed except how much history the average has to move.
How to read your score
Frequently asked questions
Is cumulative GPA the average of my term GPAs?
Only if every term carried exactly the same number of credits. Otherwise it is the credit-weighted average, and averaging your term GPAs directly will give the wrong answer.
Do retaken courses replace the original grade?
It depends on the institution. Some replace the grade entirely, some average both attempts, and some keep both on the transcript but count only the higher one. Adjust your prior credits and quality points to match your own policy.
Do transfer credits count?
Usually they count towards graduation but not towards GPA, because the grades were awarded elsewhere. Leave them out of the prior credits box unless your registrar includes them.
Why can I not reach my target in one term?
Because the target applies to all credits, old and new. If the gap is large and your prior credit count is high, no single term at any achievable GPA can close it — the calculator says so explicitly rather than returning an impossible number.

The same term GPA moves the cumulative figure less and less as credits accumulate.
