Percent to letter grade chart
This is the most common U.S. scale (it’s the one our grade calculator uses). Your school or teacher may use a different cutoff — the syllabus always wins.
| Letter | Percent | GPA (4.0 scale) |
|---|---|---|
| A+ | 97–100% | 4.0 |
| A | 93–96% | 4.0 |
| A− | 90–92% | 3.7 |
| B+ | 87–89% | 3.3 |
| B | 83–86% | 3.0 |
| B− | 80–82% | 2.7 |
| C+ | 77–79% | 2.3 |
| C | 73–76% | 2.0 |
| C− | 70–72% | 1.7 |
| D+ | 67–69% | 1.3 |
| D | 63–66% | 1.0 |
| D− | 60–62% | 0.7 |
| F | Below 60 | 0.0 |
Some schools give A+ a 4.3; others don’t use plus/minus at all (A = 90–100, B = 80–89, and so on).
How to calculate your GPA
GPA is a credit-weighted average of grade points:
GPA = Σ (grade points × credits) ÷ total credits
| Class | Grade | Points | Credits | Points × credits |
|---|---|---|---|---|
| Biology | A | 4.0 | 4 | 16.0 |
| History | B+ | 3.3 | 3 | 9.9 |
| Algebra | C | 2.0 | 3 | 6.0 |
(16.0 + 9.9 + 6.0) ÷ 10 credits = 3.19 GPA.
Rounding and borderline grades
- Many teachers round 89.5% up to 90%, but it isn’t universal — ask early in the term, not after finals.
- Your exact percent depends on the category weights. Run your numbers in the calculator before assuming you’re on the line.
