GPA Calculator: Semester and Cumulative GPA (4.0 Scale)
This GPA calculator works out your grade point average on the standard 4.0 scale. Add your courses with letter grades and credit hours to get your semester GPA, then enter your current GPA and credits to see your new cumulative GPA. High school students can add Honors and AP weighting.
Cumulative GPA (optional)

Quick answer: GPA = total grade points ÷ total credits. Multiply each course’s grade points (A = 4.0, B = 3.0 and so on) by its credits, add them up, and divide by the total credits. The calculator above does it as you type.
How to use the GPA calculator
- Replace the sample courses with yours. Pick each letter grade and enter its credit hours (units).
- Click + Add course for more rows, or × to remove one.
- Read your Semester GPA. High school students can set Honors or AP/IB to see a weighted GPA.
- To update your overall GPA, enter your current cumulative GPA and the credits you have already completed.
GPA scale used
| Grade | Points | Grade | Points |
|---|---|---|---|
| A+ / A | 4.0 | C | 2.0 |
| A- | 3.7 | C- | 1.7 |
| B+ | 3.3 | D+ | 1.3 |
| B | 3.0 | D | 1.0 |
| B- | 2.7 | D- | 0.7 |
| C+ | 2.3 | F | 0.0 |
This is the most common US college scale. Some schools give A+ a 4.3, or don’t use pluses and minuses; check your school’s catalog.
Example GPA calculation
With the sample courses: English A- (3.7 × 3 = 11.1), Calculus B+ (3.3 × 4 = 13.2), Biology A (4.0 × 4 = 16.0) and History B (3.0 × 3 = 9.0). That is 49.3 grade points over 14 credits, so the GPA is 49.3 ÷ 14 = 3.52.
How cumulative GPA works
Your cumulative GPA combines all terms, weighted by credits. Multiply your current GPA by your completed credits to get your total grade points so far, add this term’s points, and divide by all credits. Because it is weighted, a strong semester raises a GPA built on few credits much more than one built on many, so early grades matter.
Weighted vs unweighted GPA
An unweighted GPA treats every class the same on the 4.0 scale. Many high schools add 0.5 for Honors and 1.0 for AP or IB classes, giving weighted GPAs above 4.0. Colleges often recalculate GPAs their own way, so report the type your school uses.

Do pass/fail classes count?
Usually not. Leave them out unless your school counts them.
