GPA to Letter Grade
Convert GPA to a letter grade and back. The exact 4.0-scale grade-point values for every letter (A = 4.0, A− = 3.7, …) plus a cumulative-GPA-to-letter guide. Free.
Your calculator is getting ready.
It runs separately so your grades stay away from advertising. If it doesn’t appear, open it directly.
Open the calculatorLetters and grade points, both ways.
A single course converts exactly: each letter has a fixed grade-point value on the 4.0 scale. A cumulative GPA converts only approximately to one letter, because it’s an average of many courses — the bands below are a guide, not an official rule.
Worked example
A course graded A− is worth 3.7 grade points. A cumulative GPA of 3.50 sits in the “A−/B+ average” band — strong, just below an A average.
How to use the gpa to letter grade
Find the direction you need

Read the exact per-course values
A = 4.0 down to F = 0.0, with +/- steps of 0.3–0.4.
Use bands for a cumulative GPA
A 3.7+ GPA is roughly an A average; the bands below show each range.

Enter your courses to get the exact number, then read its band.
Letter grade to grade points (exact, per course)
| Letter | Grade points |
|---|---|
| A / A+ | 4.0 |
| A− | 3.7 |
| B+ | 3.3 |
| B | 3.0 |
| B− | 2.7 |
| C+ | 2.3 |
| C | 2.0 |
| C− | 1.7 |
| D+ | 1.3 |
| D | 1.0 |
| D− | 0.7 |
| F | 0.0 |
Most schools cap A+ at 4.0; a few use 4.3. Turn on or off +/- grades in the calculator to match your school.
Cumulative GPA to letter (approximate bands)
| Cumulative GPA | Rough letter average |
|---|---|
| 3.85 – 4.00 | A |
| 3.50 – 3.84 | A− / B+ |
| 3.00 – 3.49 | B |
| 2.50 – 2.99 | B− / C+ |
| 2.00 – 2.49 | C |
| 1.00 – 1.99 | D |
| below 1.00 | F |
These bands are a guide. A cumulative GPA is an average, so it doesn’t map to one official letter — schools don’t convert GPA back to a single grade.
Percentages are a separate scale
A letter can also come from a percentage (90–100 = A, 80–89 = B, …), and the percentage-to-letter cutoffs are set by each course. See GPA vs percentage for how the two scales relate.
