🎓 GPA Calculator
Work out your semester GPA from letter grades and credit hours, and see how it changes your cumulative GPA.
Quick answer: GPA = total grade points ÷ total credits. Grades of A (3 credits), B+ (3), A− (4) and B (3) give (12 + 9.9 + 14.8 + 9) ÷ 13 = 45.7 ÷ 13 ≈ 3.52.

Step by step
- Grade points per course = grade value × credits: A 4 × 3 = 12; B+ 3.3 × 3 = 9.9; A− 3.7 × 4 = 14.8; B 3 × 3 = 9
- Total grade points: 45.7; total credits: 13
- GPA = 45.7 ÷ 13 = 3.5154 ≈ 3.52

How GPA works
Your grade point average turns letter grades into a single number between 0.0 and 4.0. Each grade has a point value, and each course is weighted by its credit hours, so a 4-credit course affects your GPA more than a 1-credit one.
GPA = Σ(grade points × credits) ÷ Σ credits
Worked example
| Course | Grade | Credits | Grade points |
|---|---|---|---|
| Biology | A (4.0) | 3 | 12.0 |
| History | B+ (3.3) | 3 | 9.9 |
| Calculus | A− (3.7) | 4 | 14.8 |
| English | B (3.0) | 3 | 9.0 |
| Total | 13 | 45.7 |
GPA = 45.7 ÷ 13 ≈ 3.52.
Cumulative GPA
To combine a new term with your record, weight each by its credits. If you had a 3.20 GPA over 30 credits, your past grade points are 3.2 × 30 = 96. Adding the term above gives (96 + 45.7) ÷ 43 ≈ 3.30.
Raising your GPA
- High grades in high-credit courses move your GPA the most.
- The more credits you have completed, the harder your cumulative GPA is to shift – early semesters matter.
- Ask whether your school replaces the grade when you retake a course; many do.
- Use the cumulative section to test “what if” scenarios before choosing a course load.
Notes on scales
This calculator uses the common unweighted 4.0 scale with plus and minus grades (A− = 3.7, B+ = 3.3 and so on). Some high schools use weighted scales that give honors or AP classes an extra 0.5 or 1.0 point, and some universities award 4.3 for an A+. Leave a row’s credits empty to skip that course.
Frequently asked questions
How is GPA calculated?
Convert each letter grade to grade points (A = 4.0, B = 3.0 and so on), multiply by the course’s credit hours, add everything up and divide by the total credits. Courses with more credits count for more.
How do I calculate my cumulative GPA?
Multiply your current GPA by the credits you have already completed to get your past grade points, add this term’s grade points, and divide by the combined credits. Open the cumulative section of the calculator to do it automatically.
Is an A+ worth more than 4.0?
On the standard 4.0 scale used here, A+ and A are both 4.0. Some schools award 4.3 for an A+ – check your registrar’s policy, as the scale varies between institutions.
Do pass/fail courses count toward GPA?
Usually not. Pass/fail, audit and withdrawn courses typically carry no grade points and are left out of the GPA, although a failing grade in a graded course counts as 0.0 with full credits.
