How to use the GPA Calculator
- 1Add each course with its letter grade and credit hours.
- 2Optionally enter your previous cumulative GPA and credits.
- 3Your semester and cumulative GPA update automatically.
How GPA is calculated
Each letter grade has a point value (A = 4.0, A− = 3.7, B+ = 3.3, B = 3.0 … F = 0). Multiply each course's points by its credit hours, add them up, and divide by total credit hours. Courses with more credits count more.
Cumulative GPA combines your new semester with your previous GPA, weighted by credits: (old GPA × old credits + semester points) ÷ (old credits + semester credits).
4.0 grade scale
| Letter | Grade points | Typical percentage |
|---|---|---|
| A / A+ | 4.0 | 93–100 |
| 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 | 65–66 |
| F | 0.0 | Below 65 |
Worked example
Four classes: A in a 3-credit course (3 × 4.0 = 12), B+ in a 4-credit course (4 × 3.3 = 13.2), A− in a 3-credit course (11.1) and B in a 2-credit course (6). That is 42.3 quality points over 12 credits, so the semester GPA is 42.3 ÷ 12 = 3.53.
If you already had a 3.20 cumulative GPA over 45 credits (144 quality points), your new cumulative GPA is (144 + 42.3) ÷ 57 = 3.27. The more credits you have, the slower your cumulative GPA moves.
Frequently asked questions
What is a good GPA?
A 3.0 (B average) is generally considered good, 3.5+ is very strong, and many competitive programs look for 3.7 or higher.
Does an A+ count as more than 4.0?
At most schools an A+ is still 4.0 on the unweighted scale. Some schools count it as 4.3; check your school's policy.
What is the difference between weighted and unweighted GPA?
Unweighted GPA uses the 0–4.0 scale for every class. Weighted GPA (used by many high schools) adds extra points for honors, AP or IB classes, often +0.5 or +1.0, so it can exceed 4.0. Colleges usually recalculate GPA their own way.
How can I raise my GPA quickly?
Focus on high-credit courses, since they carry the most weight, and check whether your school lets a retaken course replace the old grade.
