How GPA and percentages convert
| Percentage | Letter | GPA points |
|---|---|---|
| 97–100% | A+ | 4.0 |
| 93–96% | A | 4.0 |
| 90–92% | A− | 3.7 |
| 87–89% | B+ | 3.3 |
| 83–86% | B | 3.0 |
| 80–82% | B− | 2.7 |
| 77–79% | C+ | 2.3 |
| 73–76% | C | 2.0 |
| 70–72% | C− | 1.7 |
| 67–69% | D+ | 1.3 |
| 63–66% | D | 1.0 |
| 60–62% | D− | 0.7 |
| 0–59% | F | 0.0 |
A percentage maps straight to a letter and its grade points. Going from GPA to a percentage is an estimate, because a GPA averages many grades: the calculator places your GPA between the two nearest letter grades and finds the matching point between the bottoms of their percentage bands.
Example: a 3.5 GPA sits halfway between a B+ (3.3, from 87%) and an A− (3.7, from 90%), so it's about 88.5%. Going the other way, 88% is a B+, worth 3.3 points.
When the conversion doesn't apply
Grading scales vary. Some schools start an A at 90% with no A−, some use a 10-point scale with no plus or minus grades, and weighted GPAs for honors and AP classes can go above 4.0. If your school publishes its own table, that's the one that counts, and many college applications ask for the GPA exactly as your transcript shows it rather than a conversion. To work out a GPA from your class grades, use the GPA calculator.
