GPA Calculator
Add your courses by letter grade or percentage to get semester and cumulative GPA, weighted and unweighted side by side — and see the GPA you need to reach a target.
How GPA is calculated
- Quality pointsgrade points × credits
- GPAtotal quality points ÷ total graded credits
- Weighted pointsgrade points + course bonus (passing grades only)
- GPA needed(target × (current + remaining credits) − current GPA × current credits) ÷ remaining credits
Pass/fail and withdrawn courses are left out. Results are shown to two decimals, rounded half up.
Worked example
The four courses the calculator starts with, on the 4.0 scale with +0.5 for honors and +1.0 for AP:
| Course | Grade × credits | Points | Weighted |
|---|---|---|---|
| English | A 4.0 × 3 | 12 | 12 |
| Chemistryhonors | B+ 3.3 × 4 | 13.2 | 15.2 |
| US HistoryAP | A− 3.7 × 3 | 11.1 | 14.1 |
| Art | C 2.0 × 2 | 4 | 4 |
Unweighted: 40.3 ÷ 12 = 3.36. Weighted: 45.3 ÷ 12 = 3.78.
With a previous 3.20 over 30 credits, the new cumulative GPA is (3.20 × 30 + 40.3) ÷ 42 = 3.25. A student at 3.00 after 60 credits needs 3.40 over the next 60 to reach 3.20 — but reaching 3.50 in 30 credits would take 4.50, which is impossible on a 4.0 scale.
Letter grade, percentage and GPA conversion
The percentage cut-offs below are a common US high-school set (A at 93%, A− at 90%, and so on), and the grade points match the registrar scales published by Indiana University, UC Santa Barbara and the University of Missouri. Schools' scales vary — some start a D at 65% or 66%, or count an A+ as 4.3 — so your transcript always wins. College Board's simplified chart, for example, uses 90–100% = A = 4.0 with no plus or minus.
| Letter | Percentage | 4.0 scale | 4.3 scale | No +/− |
|---|---|---|---|---|
| A+ | 97–100% | 4.0 | 4.3 | 4.0 |
| A | 93–96% | 4.0 | 4.0 | 4.0 |
| A− | 90–92% | 3.7 | 3.7 | 4.0 |
| B+ | 87–89% | 3.3 | 3.3 | 3.0 |
| B | 83–86% | 3.0 | 3.0 | 3.0 |
| B− | 80–82% | 2.7 | 2.7 | 3.0 |
| C+ | 77–79% | 2.3 | 2.3 | 2.0 |
| C | 73–76% | 2.0 | 2.0 | 2.0 |
| C− | 70–72% | 1.7 | 1.7 | 2.0 |
| D+ | 67–69% | 1.3 | 1.3 | 1.0 |
| D | 63–66% | 1.0 | 1.0 | 1.0 |
| D− | 60–62% | 0.7 | 0.7 | 1.0 |
| F | below 60% | 0.0 | 0.0 | 0.0 |
On the no-plus/minus scale the calculator uses 90/80/70/60% cut-offs for A/B/C/D. Sources: College Board BigFuture, "How to Convert Your GPA to a 4.0 Scale"; Indiana University, UC Santa Barbara and University of Missouri registrar grading policies. Checked 7 October 2026.
Weighted GPA: what schools do differently
Bonus size
The defaults here are +0.5 for honors and +1.0 for AP, IB and dual enrollment, which is common but not universal. Some schools weight honors and AP the same, and some don't weight dual enrollment. Every bonus is editable.
Failing and low grades
The calculator never adds a bonus to an F. Some schools also withhold it below a C; if yours does, set that course to "Regular" in the calculator.
Caps
With a 4.3 scale an A+ in AP would be 5.3. Schools that cap weighted points usually stop at 5.0; choose a cap in the weighting settings. Many colleges recalculate GPAs with their own rules anyway.
Frequently asked questions
How do I calculate my GPA?+
Turn each grade into grade points (A = 4.0, B+ = 3.3 and so on), multiply by the course's credits to get quality points, add them up and divide by the total graded credits. Four courses worth 12 credits earning 40.3 quality points give 40.3 ÷ 12 = 3.36.
What is the difference between weighted and unweighted GPA?+
An unweighted GPA treats every course the same, so 4.0 is the top. A weighted GPA adds a bonus for harder courses — commonly +0.5 for honors and +1.0 for AP, IB or dual enrollment — so an A in AP counts as 5.0. Colleges often recalculate GPAs their own way, so report the figures your school puts on your transcript.
Is an A+ worth 4.0 or 4.3?+
Both exist. Many US universities, including Indiana University, UC Santa Barbara and the University of Missouri, count an A+ as 4.0 — the same as an A. Some schools give 4.3. Pick the scale your school uses; the calculator supports both.
What is 90% as a GPA?+
On the plus/minus scale used here, 90–92% is an A− worth 3.7. On a scale without plus and minus — like College Board's simplified chart, where 90–100% is an A — it is 4.0. Percentage cut-offs vary by school, so check your handbook.
Do pass/fail and withdrawn courses count toward GPA?+
Usually not. P (pass), NP (no pass) and W (withdrawn) appear on a transcript but carry no grade points, so their credits are left out of the GPA. The calculator shows them as credits entered but not in the GPA. Some schools do count a failed pass/fail course as an F — check your policy.
How do I calculate my cumulative GPA?+
Multiply your previous GPA by the credits it covers, add this term's quality points, then divide by all graded credits together. A 3.20 over 30 credits plus a 3.36 term over 12 credits is (96 + 40.3) ÷ 42 = 3.25. You can't simply average the two GPAs, because the terms have different credit loads.
Is anything I enter saved or sent?+
No. Everything is calculated in your browser and nothing is uploaded. Your courses are kept on this device only if you tick "Remember my courses on this device", and unticking it deletes them.
