How to calculate your GPA
- Turn each letter grade into grade points (A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0).
- Multiply the grade points by the course’s credit hours. That gives you quality points.
- Add up all the quality points and all the credit hours.
- Divide total quality points by total credit hours. That’s your GPA.
Example: an A in a 3-credit class (12 points), a B+ in a 4-credit class (13.2 points) and a C in a 3-credit class (6 points) = 31.2 quality points ÷ 10 credits = 3.12 GPA.
Common 4.0 grade scale
| Letter | Points | Letter | Points |
|---|---|---|---|
| A | 4.0 | C+ | 2.3 |
| A− | 3.7 | C | 2.0 |
| B+ | 3.3 | C− | 1.7 |
| B | 3.0 | D+ | 1.3 |
| B− | 2.7 | D | 1.0 |
| F | 0.0 |
Some schools don’t use plus/minus grades or count A+ as 4.3. Always check your school’s catalog — your official transcript is what counts.
How do I calculate my cumulative GPA?
Multiply your current cumulative GPA by the credits you’ve already completed to get your past quality points. Add this semester’s quality points, then divide by your total credits (old + new). Enter both numbers in the calculator above and it does this for you.
Weighted vs. unweighted GPA
Most colleges use an unweighted 4.0 scale based on credit hours. “Weighted” GPAs (where honors or AP classes count more) are mostly used in high school.
What do I need on my final?
Needed final score = (goal grade − current grade × (1 − final weight)) ÷ final weight. For example, with an 84% now, a final worth 25% and a goal of 85%: (85 − 84 × 0.75) ÷ 0.25 = 88%. The GPA & Grade Calculator app works this out for every class and grade letter.
