Cumulative GPA Calculator
Combine your prior GPA with a new term, and see what you need next.
Please note: Grading rules vary by institution, and many schools round, cap or weight differently. Always confirm against your own syllabus or registrar before relying on a result.
What the Cumulative GPA Calculator does
Cumulative GPA combines every term by quality points, not by averaging GPAs. Prior quality points and this term’s are added, then divided by total credits — which is why a strong term moves a long transcript far less than a short one.
Formula
Quality points = GPA × CreditsCumulative GPA = (Prior QP + Term QP) ÷ (Prior credits + Term credits)Needed GPA = (Target × All credits − Current QP) ÷ Remaining credits
Inputs explained
| Input | Unit | Required | Notes |
|---|---|---|---|
| Prior cumulative GPA | number | Yes | Accepts 0 or more, up to 5. |
| Credits completed so far | number | Yes | Accepts 0 or more. |
| This term’s GPA | number | Yes | Accepts 0 or more, up to 5. |
| Credits this term | number | Yes | Accepts more than 0. |
| Target cumulative GPA | number | Optional | Accepts 0 or more, up to 5. |
| Credits remaining after this term | number | Optional | Accepts 0 or more. |
| Scale maximum | number | Optional | Accepts 0.1 or more. |
How to use it
- Enter Prior cumulative GPA, Credits completed so far, This term’s GPA and Credits this term.
- Optionally add Target cumulative GPA, Credits remaining after this term and Scale maximum.
- Select Calculate.
Worked example
A 3.4 GPA over 60 credits, then a 3.8 term over 15 credits.
- Prior GPA
- 3.4
- Prior credits
- 60
- Term GPA
- 3.8
- Term credits
- 15
(3.4 × 60 + 3.8 × 15) ÷ 75 = (204 + 57) ÷ 75 = 3.48 — not the 3.6 a simple average would suggest.
Reading the result
- "Simple average of the two GPAs" is shown deliberately as a wrong-answer contrast — the gap between it and the real cumulative figure directly measures how much the credit-load mismatch matters.
- "Best possible final GPA" (with a target and future credits entered) shows the absolute ceiling regardless of any specific target — useful for checking whether any outcome could reach a given aspiration.
Assumptions and limitations
- Prior GPA and credits are trusted as a single already-computed figure — the calculator has no visibility into what terms made up that number, so a stale or wrong prior figure propagates through everything downstream.
- "Needed GPA over remaining credits" assumes one uniform GPA across all future terms, not a different figure term to term.
Common mistakes
- Assuming the same term-GPA improvement matters equally at any point in a degree — the notes explain early terms move the cumulative figure disproportionately, so a strong senior-year term does not have the same rescuing power as a strong freshman-year one.
Frequently asked questions
Why is my cumulative GPA not the average of my term GPAs?
Because terms carry different credit loads, and because your prior total already represents many terms. A single 4.0 term against 90 prior credits barely shifts the total.
Can I still reach my target GPA?
Enter a target and your remaining credits. If the required GPA exceeds the scale maximum, it is arithmetically impossible — the earlier you know, the more options you have.
