About the GPA Calculator
GPA is total quality points divided by total credits, where a course’s quality points are its grade points (A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0) times its credits. An A, a B+ and an A− in 3-credit courses plus a B in a 4-credit course is 45 quality points over 13 credits, a 3.46. This GPA calculator uses the unweighted 4.0 scale and can combine the term with earlier ones into a cumulative figure.
Letter grades and grade points on the 4.0 scale used here
| Letter grade | Grade points | Quality points, 3-credit course | Quality points, 4-credit course |
|---|---|---|---|
| A+ | 4.0 | 12.00 | 16.00 |
| A | 4.0 | 12.00 | 16.00 |
| A− | 3.7 | 11.10 | 14.80 |
| B+ | 3.3 | 9.90 | 13.20 |
| B | 3.0 | 9.00 | 12.00 |
| B− | 2.7 | 8.10 | 10.80 |
| C+ | 2.3 | 6.90 | 9.20 |
| C | 2.0 | 6.00 | 8.00 |
| C− | 1.7 | 5.10 | 6.80 |
| D+ | 1.3 | 3.90 | 5.20 |
| D | 1.0 | 3.00 | 4.00 |
| D− | 0.7 | 2.10 | 2.80 |
| F | 0.0 | 0.00 | 0.00 |
A+ counts as 4.0, the same as A. Schools set their own scales: the College Board notes that some do not use pluses and minuses and others have different grade cutoffs. Check the key on your transcript.
A worked semester
| Course | Credits | Grade | Grade points | Quality points |
|---|---|---|---|---|
| Math 101 | 3 | A | 4.0 | 12.00 |
| History 101 | 3 | B+ | 3.3 | 9.90 |
| Physics | 4 | B | 3.0 | 12.00 |
| English | 3 | A− | 3.7 | 11.10 |
| Total | 13 | 45.00 |
These are the courses the calculator opens with. 45.00 ÷ 13 = 3.46.
What one 15-credit term does to a cumulative GPA
| GPA before | Credits before | This term (15 credits) | New cumulative GPA |
|---|---|---|---|
| 3.00 | 30 | All A (4.00) | 3.33 |
| 3.00 | 60 | All A (4.00) | 3.20 |
| 3.00 | 90 | All A (4.00) | 3.14 |
| 2.00 | 30 | All B (3.00) | 2.33 |
| 2.50 | 45 | All A− (3.70) | 2.80 |
| 3.50 | 60 | All B (3.00) | 3.40 |
| 3.70 | 90 | All C (2.00) | 3.46 |
The term is five 3-credit courses with the same grade. The more credits you already have, the less one term moves the average.
How to use this tool
- For each course, enter the credits and pick the letter grade. The course name is only a label.
- Use Add Course for another row, or the trash button to remove one.
- Read the Semester GPA, the total credits and the total quality points.
- For a cumulative GPA, fill in Current cumulative GPA and Credits completed under Earlier terms.
- Optional: under Goal GPA, enter the cumulative GPA you want and the credits still to take to see the average grade they need.
Frequently asked questions
- How do I calculate my GPA?
- Multiply each course’s grade points by its credits, add those up, and divide by the total credits. An A (4.0) in a 3-credit course and a B (3.0) in another 3-credit course is (12 + 9) ÷ 6 = 3.50.
- What GPA do I need in my remaining classes to reach my goal?
- Fill in Goal GPA and Credits still to take. The needed average is (goal × all credits − quality points so far) ÷ credits left, counting the courses on the page and any earlier terms. With the opening semester of 45.00 points over 13 credits, a 3.0 goal with 12 credits left needs (75 − 45) ÷ 12 = 2.50, about a B− in every course. A 3.8 goal would need 4.17, above the 4.0 top of the scale, so the page says it is out of reach and that straight A grades would give 3.72.
- Does it calculate a weighted GPA for honors and AP classes?
- No. It is unweighted: an A is 4.0 whatever the level of the course. The College Board notes that some schools use a weighted system in which AP and honors classes are assigned higher GPA points.
- How do I calculate my cumulative GPA?
- Multiply your current cumulative GPA by the credits behind it, add this term’s quality points, and divide by all the credits together. A 3.20 over 60 credits plus a term of 45.00 quality points over 13 credits is (192 + 45) ÷ 73 = 3.25.
- How much can one semester raise my GPA?
- It depends on how many credits you already have. A 15-credit term of straight A grades lifts a 3.00 to 3.33 after 30 earlier credits, to 3.20 after 60, and to 3.14 after 90.
- Do credits matter, or only the grades?
- Credits are the weights. An A in a 4-credit course with a C in a 1-credit course is a 3.60. Swap the credits and the same two grades give a 2.40.
