How to use
- Choose the scale — US letter grades, or a percentage conversion.
- Enter each course's credits and grade; choose Add course for more.
- Read your GPA, total credits and, for percentages, the weighted average.
Options explained
- US letter grades
- A/A+ 4.0, A− 3.7, B+ 3.3, B 3.0, B− 2.7, C+ 2.3, C 2.0, C− 1.7, D+ 1.3, D 1.0, D− 0.7, F 0. Some schools give A+ 4.3.
- Standard 4.0 (percentages)
- 90–100 = 4, 80–89 = 3, 70–79 = 2, 60–69 = 1, below 60 = 0.
- Credit weighting
- Each grade counts in proportion to its credits, so a 4-credit course weighs twice as much as a 2-credit one.
Example
Calculus (4 credits, A−), English (3 credits, B+), Chemistry (4 credits, B): GPA = (4 × 3.7 + 3 × 3.3 + 4 × 3.0) ÷ 11 = 3.34.
Example: one semester with letter grades
| Course | Credits | Grade | Grade points | Credits × points |
|---|---|---|---|---|
| Calculus | 3 | A | 4.0 | 12.0 |
| Biology with lab | 4 | B+ | 3.3 | 13.2 |
| Composition | 3 | A− | 3.7 | 11.1 |
| Art history | 2 | C | 2.0 | 4.0 |
| Total | 12 | 40.3 |
GPA = 40.3 ÷ 12 = 3.36. The 4-credit course counts twice as much as the 2-credit one, which is why a C in a small course hurts less.
Same percentages, different scales
Percentage-based schools convert scores to grade points in different ways. The same four courses — 92, 85, 78 and 66 with 3, 4, 3 and 2 credits (weighted average 81.8) — give:
| Scale | 92 | 85 | 78 | 66 | GPA |
|---|---|---|---|---|---|
| Standard 4.0 | 4 | 3 | 2 | 1 | 2.67 |
| Improved 4.0 | 4 | 4 | 3 | 2 | 3.42 |
| Peking University 4.0 | 3.88 | 3.58 | 3.09 | 1.83 | 3.24 |
When you apply abroad, check which conversion the receiving university wants — or send your transcript to a credential evaluation service.
Frequently asked questions
Is this my cumulative GPA?
Enter all your courses to get a cumulative GPA, or one term's courses for a term GPA.
Do pass/fail courses count?
Usually not. Leave them out unless your school says otherwise.
My school gives A+ a 4.3. What should I do?
This calculator uses 4.0 for A+. Check your school's scale; for a 4.3 system, results will be slightly lower here.
