The percentage range behind every letter grade, and what each one is worth on a 4.0 scale.
The scale every GradeKit calculator uses.
| Letter grade | Percentage | GPA points |
|---|---|---|
| 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 | 0–59% | 0.0 |
How it works
The plus/minus scale below is the one GradeKit’s calculators use. Each letter covers a three-point percentage band, except F, which covers everything under 60%.
Worked example
An 85% falls in the 83–86 band, which is a B, worth 3.0 grade points. An 89% falls in the 87–89 band, which is a B+, worth 3.3.

Before you rely on the number
Common questions
On the standard plus/minus scale, 85% is a B. On a straight 10-point scale it is also a B, since 80–89 forms a single band.
On the plus/minus scale used here, 90–92 is an A−, and an A starts at 93. On a 10-point scale, 90 is a plain A.
A 3.0 corresponds to a B, which is 83–86% on the plus/minus scale. Cumulative GPA is an average across courses, so it maps to a percentage only loosely.
