GPA Scale Chart
GPA scale lookup
Type a letter grade (B+), a percent (87) or a 4.0-scale GPA (3.3).
On the standard US scale an A is 4.0, a B is 3.0, a C is 2.0, a D is 1.0 and an F is 0.0, with plus and minus grades in between (A- = 3.7, B+ = 3.3). Weighted scales add 0.5 for Honors and 1.0 for AP or IB, which gives a 5.0 maximum.
Worked example
You scored 87% in an AP class.
- 87% is a B+ in the chart below
- B+ = 3.3 on the unweighted 4.0 scale
- AP adds 1.0, so the weighted value is 4.3
Letter grade to 4.0 and weighted 5.0
| Letter | Percent | Unweighted 4.0 | Honors | AP / IB (5.0 scale) |
|---|---|---|---|---|
| A+ | 97–100 | 4.0 | 4.5 | 5.0 |
| A | 93–96 | 4.0 | 4.5 | 5.0 |
| A- | 90–92 | 3.7 | 4.2 | 4.7 |
| B+ | 87–89 | 3.3 | 3.8 | 4.3 |
| B | 83–86 | 3.0 | 3.5 | 4.0 |
| B- | 80–82 | 2.7 | 3.2 | 3.7 |
| C+ | 77–79 | 2.3 | 2.8 | 3.3 |
| C | 73–76 | 2.0 | 2.5 | 3.0 |
| C- | 70–72 | 1.7 | 2.2 | 2.7 |
| D+ | 67–69 | 1.3 | 1.8 | 2.3 |
| D | 63–66 | 1.0 | 1.5 | 2.0 |
| D- | 60–62 | 0.7 | 1.2 | 1.7 |
| F | Below 60 | 0.0 | 0.0 | 0.0 |
Frequently asked questions
What is the standard GPA scale?
A = 4.0, B = 3.0, C = 2.0, D = 1.0 and F = 0.0, with pluses and minuses at 0.3 or 0.4 intervals in between.
What percent is an A?
Usually 93 to 100, with an A- at 90 to 92. Some schools use 90 as the cutoff for any A, so check your grading policy.
What is a 5.0 scale?
A weighted scale where an A in an AP, IB or dual-enrollment class is worth 5.0 and an A in an Honors class is worth 4.5.
Is an A+ 4.0 or 4.33?
Most schools cap an A+ at 4.0. A few colleges use 4.33. This chart uses 4.0.
Do all schools use these cutoffs?
No. Some use a 10-point scale (90/80/70/60) without plus and minus, or different bonuses for weighted classes. The chart shows the most common version.
How do I convert my percent to GPA?
Find your percent in the chart, read the unweighted value, then add the Honors or AP bonus if the class was weighted.
