Semester GPA Calculator
Calculate your semester GPA from courses with letter grades and credit hours.
Also computes cumulative GPA with prior credits.
How Semester GPA Is Calculated
GPA (Grade Point Average) is a weighted average of your grades, where each course is weighted by its credit hours. This means a 4-credit course impacts your GPA more than a 1-credit course.
Grade Point Scale (standard US):
| Letter Grade | Grade Points |
|---|---|
| A / A+ | 4.0 |
| A− | 3.7 |
| B+ | 3.3 |
| B | 3.0 |
| B− | 2.7 |
| C+ | 2.3 |
| C | 2.0 |
| D | 1.0 |
| F | 0.0 |
GPA Formula:
GPA = Sum(Grade Points × Credit Hours) / Sum(Credit Hours)
Worked Example:
| Course | Credits | Grade | Points | Quality Points |
|---|---|---|---|---|
| Calculus | 4 | A− | 3.7 | 14.8 |
| Chemistry | 3 | B+ | 3.3 | 9.9 |
| English Comp | 3 | A | 4.0 | 12.0 |
| Physics Lab | 1 | B | 3.0 | 3.0 |
- Total Quality Points = 14.8 + 9.9 + 12.0 + 3.0 = 39.7
- Total Credits = 4 + 3 + 3 + 1 = 11
- Semester GPA = 39.7 / 11 = 3.61
Cumulative GPA: Calculated the same way but using all semesters’ totals combined.
Why one semester moves your cumulative GPA so little
This is the thing students consistently get wrong, and it works in both directions. Suppose you have 60 credits banked at a 3.50 and you post a 3.61 this semester across 11 credits. Your cumulative barely twitches: it goes to 3.52. A tenth of a point of improvement, on a fifth of your total credits, moves the average by less than two hundredths.
The arithmetic is simply that your cumulative GPA is an average weighted by credit hours, and by your third year the credits already on the transcript outnumber the ones still to come. Enter your prior GPA and credits above and the calculator will show you the exact shift rather than the one you are hoping for.
Two practical consequences. Early semesters matter far more than late ones, because a bad first year sits in the denominator of every calculation you make afterwards. And if you are trying to lift a cumulative GPA in your final year, the honest answer is usually that you cannot move it much, which is worth knowing before you build a plan around it. Retaking a course sometimes helps, but only where your school replaces the old grade rather than averaging both, and that policy varies enough that you should check it rather than assume.
Minimum GPA Benchmarks:
- Academic good standing: typically 2.0
- Dean’s List: usually 3.5+
- Magna Cum Laude: typically 3.7+
- Summa Cum Laude: typically 3.9+
