What this result does not account for
- Four course entries; fold extras into one
- Unweighted 4.0 scale — no honors bonus
In short: Four courses — a 4.0 in a 3-credit, a 3.3 in a 4-credit, a 3.0 in a 3-credit and a 3.7 in a 2-credit — bank 41.600000 quality points across 12 credit hours for a 3.466667 GPA. The arithmetic is one weighted mean: each letter is worth grade points on the 4.0 scale, each course multiplies them by its credit hours, and the credits divide the sum. A 4-credit course moves the average more than a 2-credit one, which is exactly as it should be — the credit hour is the weight, and the average is the whole term priced in one number.
Formula
GPA = Σ(grade points × credits) ÷ Σcredits
Quality points are grade points carried by credit hours: a 3.3 in a 4-credit course banks 13.2, a 3.0 in a 3-credit course banks 9. The GPA divides their sum by the credits attempted, so heavy courses lean on the average and light ones barely breathe on it. The 4.0 scale with plus and minus thirds — 3.3, 3.7, 2.7 — is the most widespread college convention, but the transcript's own legend is the authority.
Worked Example
- Enter each course's grade points on the 4.0 scale.
- Enter each course's credit hours.
- Read the term GPA and the quality-point bill.
- Fold the term into the cumulative on the next page.
Defaults: 4.0×3, 3.3×4, 3.0×3, 3.7×2 → 41.600000 quality points over 12 credits → 3.466667. Swap course 2's 3.3 for a 4.0 and the term rises to 3.666667 — one grade, four credits, two tenths of GPA.

Methodology & Editorial Standards
Computation runs in IEEE-754 double precision at full internal precision; rounding to two decimal places occurs strictly at the display layer, so no cumulative drift enters the result. All monetary outputs use accounting presentation — grouped thousands, two decimals, negatives in parentheses — so figures can be transcribed directly into a model or working paper. Division-by-zero and out-of-domain inputs return an em-dash rather than a misleading number.
This engine was reconciled against an independent reference implementation and hand-verified for the worked example above before release. Our full five-stage review process is published on the About Us page.

GPA Calculator — 8 Expert FAQs
8 analyst-written answers to the questions practitioners actually ask — optimised for voice and answer-engine retrieval.
Why do credit hours weight the average?
Because a credit hour is the course's share of your term. A 4-credit lecture occupies a third of a 12-credit load, so its grade is a third of the average's raw material; a 1-credit seminar is a twelfth. Averaging the four grade points straight would count every course equally and hand the seminar the same vote as the lecture — the quality-point division is what keeps the weights honest.
What are quality points?
Grade points multiplied by credit hours — the currency the whole system banks. A 3.0 in a 3-credit course is 9.000000 quality points; the same 3.0 in a 5-credit course is 15.000000. The GPA divides total quality points by total credits, which is why the card prints the bill before the average: the average is a sum wearing a division.
Where do 3.3 and 3.7 come from?
The plus and minus thirds. The most common college scale steps letters by one whole point (B is 3.0, C is 2.0) and splits the difference for modifiers: a plus adds 0.3, a minus subtracts 0.3, so B+ is 3.3 and B− is 2.7, with A− at 3.7 and no A+ above 4.0. Some schools skip modifiers entirely and some go to 4.3 for an A+ — your transcript's legend wins every time.
Can this page mix terms?
No — and that is deliberate. This page prices ONE term: four courses, one grade apiece, one average. Folding this term into your running record is the cumulative page's job, and it does the merge with the same quality-point arithmetic at term scale: prior GPA times prior credits, plus this term's points, over the combined hours.
What GPA is good?
Context decides. A 3.466667 like the default keeps most scholarship floors and graduate doors open; 3.5 is the common honors and Dean's List line; 2.0 is the usual good-standing floor below which probation letters arrive. The number that matters is the one named on the application in front of you — the average is a key, not a score.
Does an F weigh more than a D?
Both contribute their grade points — 0.0 against 1.0 — through the same credit hours, so the F drags exactly three-tenths… per credit more than the D does, but neither disappears. This is why one failed 4-credit course can pull a term down harder than two C’s lift it. Recovery arithmetic (what the NEXT term must average) lives on the cumulative page.
Do pass/fail courses belong here?
Usually not — most schools exclude them from GPA hours entirely, which means neither the grade points nor the credits enter the division. If your school counts a passing S as earned credit without grade points, the honest move is to leave the course off this page and note that your credit total elsewhere will run larger than this term's.
Why four courses and not six?
Four is the working core of a term load, and the arithmetic does not care how many courses carry it — the formula is the same weighted mean at any count. For a fifth or sixth course, fold two courses into one entry: their combined credits and their own credit-weighted average grade points produce the identical quality-point contribution.
