Letter Grade to GPA
Pick a letter grade and see exactly what it is worth: its points on the 4.0 scale and the percentage band behind it. The full chart is printed below — all thirteen letter grades, A+ to F.
A B+ is worth…
3.3 GPA points
On the standard scale a B+ is a percentage of 87% up to the next band. In a 3-credit course it banks 9.9 quality points toward your GPA.
Every letter grade and its GPA points
| Letter grade | GPA points | Percentage |
|---|---|---|
| A+ | 4.0 | 97–100 |
| A | 4.0 | 93–96 |
| A- | 3.7 | 90–92 |
| B+ | 3.3 | 87–89 |
| B | 3.0 | 83–86 |
| B- | 2.7 | 80–82 |
| C+ | 2.3 | 77–79 |
| C | 2.0 | 73–76 |
| C- | 1.7 | 70–72 |
| D+ | 1.3 | 67–69 |
| D | 1.0 | 63–66 |
| D- | 0.7 | 60–62 |
| F | 0.0 | Below 60 |
Percentage bands are the common US convention used across this site: A+ 97–100, A 93–96, A− 90–92, then three-point bands down to D− 60–62, with F below 60. Your school may set its own cutoffs — if it publishes them, its table wins.
To turn a GPA number back into a letter, use the GPA to letter grade lookup. To average a whole list of letter grades into a GPA, that is the GPA calculator; the scale itself, including the weighted version, is charted on the GPA scale page.
Frequently asked questions
What is a B+ in GPA points?+
A B+ is worth 3.3 points on the standard 4.0 scale, and it stands for a percentage of 87–89%. In a 3-credit course a B+ banks 9.9 quality points — 1.2 points behind the 11.1 an A− would bank in the same course, which is why the +/− steps matter at GPA boundaries.
What GPA is an A−?+
An A− is worth 3.7 points, for a percentage of 90–92%. It is the most consequential step on the scale for strong students: a semester of A− grades gives a 3.7 GPA, which sits in magna cum laude territory at many colleges, while straight A's give the full 4.0.
Is a C− worth 1.7 or 2.0?+
1.7. The plain C is the 2.0 band (73–76%); C− is the step below it at 1.7 points (70–72%). The distinction matters because 2.0 is the good-standing line at most colleges — a record of C− grades averages below it, even though every course was technically passed.
What is the GPA for a D+?+
A D+ is worth 1.3 points, for a percentage of 67–69%. It is a passing grade at most schools, but barely: a semester of D+ grades produces a 1.3 GPA, below the 2.0 line for good standing, probation and most transfer applications.
Does an A+ count as 4.0 or 4.3?+
On the standard 4.0 scale, 4.0 — an A+ and an A earn the same points, which is why a student with A+ grades can still have exactly a 4.0. Some schools run a 4.33 scale where the A+ alone counts 4.33. If your transcript shows a GPA above 4.0 without weighted courses, that second scale (or a weighted one) is probably what your school uses.
How much is one letter grade worth to my GPA?+
One step — say B to B+ — is 0.3 points in that course. Spread over a semester it moves your GPA by 0.3 × (course credits ÷ total credits): in a 3-credit course inside a 15-credit semester, one step is worth 0.06 GPA points. Small per course, decisive across a transcript — five one-step improvements in a year is roughly a third of a GPA point.
