How to convert a percentage to a letter grade
To convert a percentage to a letter grade, compare it with the minimum percent for each letter and take the highest one you reached. An 86% passes the 83% minimum for a B but not the 87% for a B+, so it is a B. For a raw score, divide first: 43 out of 50 is 86%.
The cut-offs used here are published by several official sources and agree from the A down: College Board’s plus/minus table, the AAMC’s conversion guide for medical school applicants and LSAC’s table for law school applicants all start the A at 93%, the A− at 90% and the B+ at 87%.[1][2][3] Whole-letter schools simply use 90, 80, 70 and 60.[4]
Percentage to letter grade chart
Every whole percent from 100 down to 56, with its letter on the 10-point plus/minus scale and its value on the 4.0 GPA scale.[2]
| % | Letter | GPA | % | Letter | GPA | % | Letter | GPA |
|---|---|---|---|---|---|---|---|---|
| 100% | A+ | 4.0 | 85% | B | 3.0 | 70% | C− | 1.7 |
| 99% | A+ | 4.0 | 84% | B | 3.0 | 69% | D+ | 1.3 |
| 98% | A+ | 4.0 | 83% | B | 3.0 | 68% | D+ | 1.3 |
| 97% | A+ | 4.0 | 82% | B− | 2.7 | 67% | D+ | 1.3 |
| 96% | A | 4.0 | 81% | B− | 2.7 | 66% | D | 1.0 |
| 95% | A | 4.0 | 80% | B− | 2.7 | 65% | D | 1.0 |
| 94% | A | 4.0 | 79% | C+ | 2.3 | 64% | D | 1.0 |
| 93% | A | 4.0 | 78% | C+ | 2.3 | 63% | D | 1.0 |
| 92% | A− | 3.7 | 77% | C+ | 2.3 | 62% | D− | 0.7 |
| 91% | A− | 3.7 | 76% | C | 2.0 | 61% | D− | 0.7 |
| 90% | A− | 3.7 | 75% | C | 2.0 | 60% | D− | 0.7 |
| 89% | B+ | 3.3 | 74% | C | 2.0 | 59% | F | 0.0 |
| 88% | B+ | 3.3 | 73% | C | 2.0 | 58% | F | 0.0 |
| 87% | B+ | 3.3 | 72% | C− | 1.7 | 57% | F | 0.0 |
| 86% | B | 3.0 | 71% | C− | 1.7 | 56% | F | 0.0 |
Below 60% is an F (0.0) on this scale. A few tables differ at the edges: College Board’s puts the A+ at 97%, LSAC’s at 98%, and College Board’s starts the D at 65% with no D−.[1][3] Pick “College Board table” in the converter to use that version.
Letter grade to GPA and percent
A letter grade stands for a range of percents but a single grade-point value. A B+ covers 87% to just under 90% and is worth 3.3 points on the 4.0 scale; a B− covers 80–82% and is worth 2.7.[2]
| Letter | Percent | GPA points |
|---|---|---|
| A | 93–100 | 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 |
When you need one percent for a letter, use the bottom of the range, because that is the score needed to earn it; the what do I need on my final tables do the same. To turn a list of letters into one number, use the GPA calculator.
Rounding at the boundaryWhether 89.5% becomes an A− is up to your teacher or school. The converter never rounds, so an 89.99% shows as a B+.
Other grading scales
Older and local scales still exist, such as scales where an A starts at 93% and a D at 70%, and countries outside the U.S. grade very differently. The grading scale guide compares U.S. state scales, college scales and the UK, Australian and Canadian systems. To get the percent itself, use the grade calculator or the test grade calculator.
Frequently asked questions
What letter grade is an 86%?
A B. On the plus/minus scale a B runs from 83% to just under 87%.
Is an 89.5 an A or a B?
Without rounding it is a B+. Some teachers round 89.5% up to 90%, which makes it an A−; your syllabus decides.
What letter grade is a 75?
A C. On a 10-point scale a C runs from 70% to 79%; with plus and minus grades, 73–76% is a C.
What percent is a C?
70–79% on a 10-point scale: 70–72% is a C−, 73–76% a C and 77–79% a C+.
What GPA is a B+?
