GPA Calculator

List your courses as “grade credits” separated by commas — for example A 3, B+ 4, C 2. The calculator converts each grade to points on a 4.0 scale and weights by credits.

AnswerGPA 3.36

12 credits
40.3 quality points

Step-by-step working 3 steps

1
Convert each grade to grade points (4.0 scale)
```
A (4.0) × 3 credits = 12
B+ (3.3) × 4 credits = 13.2
A- (3.7) × 3 credits = 11.1
C (2.0) × 2 credits = 4
```
Scale used: A/A+ 4.0, A− 3.7, B+ 3.3, B 3.0, B− 2.7, C+ 2.3, C 2.0, C− 1.7, D+ 1.3, D 1.0, D− 0.7, F 0. Schools differ — check yours.
2
Add quality points and credits
```
Quality points = 40.3
Credits = 12
```
3
GPA = quality points ÷ credits
```
40.3 ÷ 12 = 3.3583
```

Common mistakes to avoid

Averaging grades without credits

A 4-credit course counts more than a 1-credit course.

Using the wrong scale

Some schools give A+ extra points or use plus/minus differently; check your own.

Counting pass/fail courses

These usually do not enter the GPA.
