GPA Calculator
Add your courses, their credits and your grades. You get your GPA on the standard 4.0 scale as you type — then blend in previous semesters for your cumulative GPA, switch on weighting for Honors and AP courses, or set a target and see exactly what you need to average to reach it.
Your GPA (unweighted, 4.0 scale)

| Course | Grade | Points | Credits | Quality points |
|---|---|---|---|---|
| English | A- | 3.7 | 3.0 | 11.1 |
| Biology | B+ | 3.3 | 4.0 | 13.2 |
| History | A | 4.0 | 3.0 | 12.0 |
| Math | B | 3.0 | 3.0 | 9.0 |
Blend in your previous semesters
Adding this semester (3.48 over 13.0 credits) moves your cumulative GPA to 3.42.
Target mode — what do I need?
You need to average 3.81 across those 15 credits to reach a 3.5 cumulative GPA.
How GPA works — one example, start to finish
The calculator above starts pre-filled with this semester: English A− (3 credits), Biology B+ (4 credits), History A (3 credits), Math B (3 credits). On the 4.0 scale those grades are worth 3.7, 3.3, 4.0 and 3.0 points. Multiply points by credits: 11.1 + 13.2 + 12.0 + 9.0 = 45.3 quality points. Divide by 13 credits: GPA = 3.48.
Now blend it into a record. Say those courses sit on top of a 3.4 cumulative GPA built over 45 credits — that record holds 3.4 × 45 = 153 quality points. Combined: (153 + 45.3) ÷ (45 + 13) = 3.42 cumulative. Notice the blend moved less than the semester GPA — the more credits behind you, the heavier your GPA is to move. That is not a flaw in the maths; it is the single most useful thing to understand about GPA planning, and it is why target mode above sometimes answers "impossible this semester" — honestly, with the numbers to show why.

Still revising for a final?
If a course grade is not final yet, the question that matters is what you need on the exam. The final grade calculator turns your current grade and the final's weight into the exact score to aim at — then come back here and see what that grade does to your GPA.

Frequently asked questions
How is GPA calculated?+
Each letter grade is worth grade points on the 4.0 scale (A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0.0, with +/− steps in between). Multiply each course's points by its credits to get quality points, add them all up, and divide by the total credits. Four courses worth 45.3 quality points over 13 credits give a GPA of 3.48. The full scale is printed on our methodology page.
What is a good GPA?+
A 3.0 is a B average — solid, and the minimum many programmes, scholarships and employers ask for. A 3.5 and above is strong; 3.7+ puts you in honours territory at most schools. But 'good' depends on the door you are aiming at: graduate programmes, competitive majors and some scholarships set their own bars, often 3.0–3.5. Check the requirement that matters to you, then use target mode above to see what it takes to reach it.
How do I work out my cumulative GPA?+
Blend by credits, not by averaging semester GPAs. Multiply your existing cumulative GPA by the credits behind it, add this semester's quality points, and divide by the new total credits. A 3.4 across 45 credits plus a 3.48 semester of 13 credits gives (153 + 45.3) ÷ 58 = 3.42 — the blend section above does it for you, and the cumulative GPA calculator handles a term-by-term history.
What GPA do I need this semester to raise my overall GPA?+
That is target mode, below the semester calculator. Enter your current cumulative GPA, the credits behind it, the GPA you want, and how many credits you are taking. The tool returns the average you need — and is honest when the maths says impossible: a GPA built over 90 credits barely moves in one 15-credit semester, which is worth knowing before you plan around it.
What is the difference between weighted and unweighted GPA?+
Unweighted GPA uses the plain 4.0 scale for every course. Weighted GPA adds bonus points for harder courses — commonly +0.5 for Honors and +1.0 for AP or IB, so an A in AP can be worth 5.0. Schools weight differently, and some do not weight at all, which is why the bonuses above are editable. Many colleges recalculate an unweighted GPA from your transcript anyway, so both numbers matter.
Does GPA round up? Is a 3.45 a 3.5?+
No — GPA is reported as calculated, usually to two decimal places, and a 3.45 stays a 3.45. That is why small differences in one course can matter at boundaries like 3.0 or 3.5, and why it pays to check what a single grade change does with the calculator before grades are final.
