How GPA is calculated
A weighted average is the standard in most education systems because courses don't count equally — a 4-credit course affects your GPA more than a 1-credit course. The formula: GPA = Σ(grade points × credits) ÷ Σ credits.
Example
Calculus A (4.0) × 4 credits, Physics B+ (3.3) × 3 credits, English B (3.0) × 3 credits: total points = 16 + 9.9 + 9 = 34.9, total credits = 10, so GPA = 3.49.
How to use it
- Choose a grading system: 4.0 GPA (US and many international universities), out of 20 (France and North Africa) or out of 100.
- Enter each course name (optional), its credits or weight, and your grade.
- Add as many courses as you need.
- Your average, percentage and standing appear instantly and are saved on your device.
Cumulative GPA
To update your cumulative GPA, enter your previous cumulative GPA and the credits it covers. The calculator combines them with this semester: (old GPA × old credits + semester points) ÷ (old credits + semester credits).
Standard letter-grade points
| Letter | Points |
|---|---|
| A / A+ | 4.0 |
| A- | 3.7 |
| B+ | 3.3 |
| B | 3.0 |
| B- | 2.7 |
| C+ | 2.3 |
| C | 2.0 |
| D | 1.0 |
| F | 0.0 |
Some schools use different point values (e.g. A+ = 4.3) or weighting for honors courses. Check your institution's official policy. For focused study sessions, try the Pomodoro Timer.
Frequently Asked Questions
What is a good GPA?
Generally 3.0+ is considered good and 3.5+ excellent, though expectations vary by program and employer.
How do I calculate cumulative GPA?
Choose the 4.0 system, enter this semester's courses, then your previous cumulative GPA and credits.

Common mappings are 90–100% = A (4.0), 80–89% = B (3.0), 70–79% = C (2.0), 60–69% = D (1.0), but schools differ.
Is my data saved?
