About this GPA calculator
Your GPA (grade point average) is the single most-quoted number on a U.S. transcript. Scholarship committees, athletic eligibility (NCAA), graduate schools and most employers that ask for a transcript all look at it.
This calculator works exactly the way American high schools and colleges do: every letter grade converts to points on the 4.0 scale, each course is weighted by its credit hours (or units), and the average is taken across all of them. It supports plus/minus grades (A–, B+ and so on), which most U.S. institutions use.
If you already have a GPA from previous semesters, enter it in the "Cumulative GPA" section together with the credits you have earned so far — the calculator will combine your new semester with your academic history, the same way your registrar does.
How the GPA formula works
Every letter grade maps to a fixed number of points (A = 4.0, B = 3.0, and so on — see the table below). Multiply each course's points by its credit hours, add everything up, and divide by the total number of credits. A 4-credit A therefore counts twice as much as a 2-credit A.
Example: Biology (4 credits, A) = 16 points; Math 101 (3 credits, B+) = 9.9 points; History (3 credits, B) = 9 points. Total: 34.9 points across 10 credits → GPA = 34.9 ÷ 10 = 3.49.
Letter grade to 4.0 GPA scale (standard U.S. conversion)
| Letter grade | Typical percent range | 4.0 scale value |
|---|---|---|
| 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 |

- Enter credit hours and letter grades: Type the credit hours for each course and pick the letter grade you received (or expect). Plus and minus grades are supported.
- Read your GPA instantly: Your semester GPA appears as you type. To see your cumulative GPA, add your previous GPA and total credits earned so far.
Frequently asked questions
Is a 3.5 GPA good?
Yes. A 3.5 unweighted GPA is well above the U.S. high school average (around 3.0) and typically lands on the dean's list in college. It is competitive for most merit scholarships and graduate programs; the most selective universities admit students with averages closer to 3.9–4.0.
How is GPA calculated with credit hours?
Each course contributes its grade points multiplied by its credit hours. Divide the total points by total credits: a 4-credit A (16 points) outweighs a 3-credit B (9 points). That is why a difficult 4-credit science course moves your GPA more than a 1-credit seminar.
What is a 3.7 GPA in percentage?
On the standard conversion table, 3.7 corresponds to an A–, typically 90–92 percent. Exact percentages vary by school because teachers grade differently, but the letter-to-point scale is what colleges use to compare transcripts.
Do plus and minus grades count toward GPA?
At most U.S. institutions, yes: a B+ is worth 3.3 and an A– is worth 3.7. A few schools ignore the minus sign or cap A+ at 4.0. This calculator uses the standard +/- scale, so pick the exact grade from your transcript for an accurate result.
