Cumulative GPA Calculator
Combine semester GPAs, weighted by credits, into one cumulative GPA.
StudentsAcross 45 total credits
If you know your GPA for each semester but not your overall figure, this is the right tool. Enter one row per semester with its GPA and the credits you completed, and the calculator weights each semester properly before averaging. That weighting matters: semesters rarely carry the same number of credits, and a plain average of the semester GPAs gives the wrong answer whenever they differ.
How to use the Cumulative GPA Calculator
- Add one row per completed semester.
- Enter that semester GPA.
- Enter the credits completed in that semester.
- Read your cumulative GPA and total credits.
Formula
This is algebraically identical to calculating from every individual course, as long as each semester GPA was itself credit-weighted, which official semester GPAs are.
Worked example
Semester GPAs of 3.40 (15 credits), 3.10 (18 credits) and 3.80 (12 credits) combine as (3.40 x 15 + 3.10 x 18 + 3.80 x 12) / 45 = (51 + 55.8 + 45.6) / 45 = 152.4 / 45 = 3.39. The simple average of the three GPAs, 3.43, overstates the result because the strongest semester was also the lightest.
Good to know
You can also fold in a planned semester: add a row with the GPA you hope to earn and its credits to preview your cumulative figure, which is the basis of the Raise GPA Calculator. If one of your semesters was taken pass/fail or at another institution whose credits transferred without grades, leave it out entirely; transfer credits normally count toward your degree total but not toward the GPA of the receiving institution.
US grading scale reference
The table below is the US plus/minus scale used across this site. Where this tool offers other scales, the Canadian scale sets an A from 85% with a pass at 50%, and the Australian scale uses the bands HD (85%+), D (75-84%), C (65-74%), P (50-64%) and F (below 50%) on a 7.0 GPA.
| Letter grade | Percentage | GPA points |
|---|---|---|
| A+ | 97–100% | 4.0 |
| A | 93–96% | 4.0 |
| A- | 90–92% | 3.7 |
| B+ | 87–89% | 3.3 |
| B | 83–86% | 3.0 |
| B- | 80–82% | 2.7 |
| C+ | 77–79% | 2.3 |
| C | 73–76% | 2.0 |
| C- | 70–72% | 1.7 |
| D+ | 67–69% | 1.3 |
| D | 63–66% | 1.0 |
| D- | 60–62% | 0.7 |
| F | 0–59% | 0.0 |
Frequently asked questions
Why not just average my semester GPAs?
Because semesters carry different credit loads. A 3.8 semester of 12 credits should move your cumulative GPA less than a 3.1 semester of 18 credits, and only the credit-weighted formula respects that.
Can I include a future semester to plan ahead?
Yes. Add the planned semester with your target GPA and expected credits to preview the cumulative result. The Raise GPA Calculator inverts the question and solves for the GPA you need.
Do transfer credits count in cumulative GPA?
Usually the credits count toward graduation but the grades do not transfer, so the GPA is calculated only from courses taken at your current institution. Leave transfer semesters out.
What if a semester was pass/fail?
Exclude it. Pass/fail courses carry credits toward a degree but no grade points, so including the semester would distort the weighted average.
How many semesters does a degree have?
A four-year bachelor degree has eight semesters (or twelve quarters). Enter as many rows as you have completed; the calculator handles any number.
