GPA Calculator
A GPA, or grade point average, turns each letter grade into points and averages them, weighting each course by its credits. This calculator works out the GPA for a semester and, if you add your previous record, your cumulative GPA.
GPA = Σ(grade points × credits) ÷ Σ(credits)
Most US colleges use a 4.0 scale. Some schools give A+ extra points on a 4.3 scale, and many Korean universities use a 4.5 scale.
How to use
- Choose the grade scale your school uses.
- Enter each course’s credits and choose its grade. Add as many courses as you need.
- To see your cumulative GPA, enter your GPA and credits so far under Previous record.
Key terms
Credits
Credits, also called credit hours or units, show how much a course counts. A 4-credit course moves your GPA twice as much as a 2-credit course with the same grade.
Cumulative GPA
The GPA across every semester so far. It is not the average of semester GPAs, because each semester is weighted by the credits taken.
Three common grade scales
Grade points differ by school. These are three published examples. Check your own school’s rules for the exact values.
| Grade | 4.0 (UC Berkeley) | 4.3 (Seoul National University) | 4.5 (Ajou University) |
|---|---|---|---|
| A+ | 4.0 | 4.3 | 4.5 |
| A / A0 | 4.0 | 4.0 | 4.0 |
| A- | 3.7 | 3.7 | – |
| B+ | 3.3 | 3.3 | 3.5 |
| B / B0 | 3.0 | 3.0 | 3.0 |
| C / C0 | 2.0 | 2.0 | 2.0 |
| D / D0 | 1.0 | 1.0 | 1.0 |

FAQ
Do pass/fail courses count?
Usually not. Leave out courses graded pass/fail or S/U, which most schools exclude from GPA.
Does an F count toward GPA?
Yes. An F adds credits with 0 points, which lowers the average.
Can I convert a 4.5 GPA to a 4.0 scale?
Not exactly. Grade points per letter differ between scales, so a fair conversion needs your individual grades. Recalculate them here on the other scale instead.
Are my grades saved?
No. Nothing is saved or sent to a server. All calculations happen in this browser.
