GPA Calculator
One course per line: grade and credits, such as A 3 or 3.7 4. Default letters use a 4.0 scale. Your school may differ.

How to calculate GPA
- Pick 4.0 or 5.0. 5.0 rescales 4.0 letter points.
- Enter one course per line. Credits are optional; omit them for unweighted lines.
- Read GPA, quality points, credits, and course count.
- Plus/minus letters use a common 4.0 map. Your registrar may use another.
GPA
Credit-weighted mean of grade points
| Letter map | A+=4, A=4, A-=3.7, B+=3.3, B=3, B-=2.7, C+=2.3, C=2, C-=1.7, D+=1.3, D=1, D-=0.7, F=0 |
|---|---|
| Formula | Sum(points × credits) / sum(credits) |
| 5.0 scale | 4.0 points × 5/4 |
Weighted GPA from lines of courses
Each line is a letter or numeric grade and the credit hours, such as A 3 or 3.7 4. GPA is total quality points divided by total credits. Letter map on the 4.0 scale: A and A+ = 4.0, A− = 3.7, B+ = 3.3, B = 3.0, and so on down to F = 0.
4.0 and 5.0 scales
The 5.0 option rescales each 4.0 point value by 5/4 (an A becomes 5.0). It is not a weighted-honors table where only some courses are 5.0. Schools that use A+ = 4.3 or percentage bands need a different map.

Registrars drop, retake, and weight courses with rules this page does not encode. Use it to check a semester average. Repeat a course only if you include the line. Pair with the percentage calculator if you need a percent of points, not a GPA.
