How to use it
- Enter each course with its credit hours and the letter grade you got or expect.
- Add or remove rows for all your courses this term.
- Optionally enter your current cumulative GPA and the credits it's based on.
- Read your semester GPA and new cumulative GPA.
How GPA is calculated
Each letter grade is worth a number of grade points on the 4.0 scale. Multiply each course's grade points by its credit hours to get quality points, add them up, and divide by the total credits:
GPA = Σ(grade points × credits) / Σ(credits)
The calculator uses this common scale:
| 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 |
Some schools give an A+ 4.3, use 3.67 and 3.33 instead of 3.7 and 3.3, or don't use plus and minus grades at all. Check your registrar's scale; the method is the same.
Example 1: one semester
| Course | Credits | Grade | Points | Quality points |
|---|---|---|---|---|
| English 101 | 3 | A | 4.0 | 12.0 |
| Calculus I | 4 | B+ | 3.3 | 13.2 |
| Biology | 4 | A− | 3.7 | 14.8 |
| History | 3 | B | 3.0 | 9.0 |
| Total | 14 | 49.0 |
Semester GPA: 49.0 / 14 = 3.50. The 4-credit courses count for more than the 3-credit ones, which is why a B+ in Calculus moves the GPA more than the B in History.
Example 2: cumulative GPA
Before this semester you had a 3.20 GPA over 30 credits. That's 3.20 × 30 = 96 quality points.
- Quality points after this semester: 96 + 49 = 145.
- Credits: 30 + 14 = 44.
- New cumulative GPA: 145 / 44 = 3.30.
You can't average the two GPAs (3.20 and 3.50 would give 3.35) because they're based on different numbers of credits. The calculator weights them correctly. The more credits you have, the slower your cumulative GPA moves, so raising it late in a degree takes many strong semesters.
Weighted, unweighted and pass/fail
- Unweighted GPA uses the 4.0 scale for every class. That's what this calculator does.
- Weighted GPA in many high schools adds points for honors, AP or IB classes, often +0.5 or +1.0, so an A in an AP class counts as 5.0. Policies vary by school and district. Colleges often recalculate GPAs in their own way.
- Pass/fail, audit and withdrawn courses usually don't count toward GPA. Leave them out.
- Repeated courses: many colleges replace the original grade with the new one, or average them. Follow your school's policy.
If your school uses a percentage scale or a different point system, convert using the scale your registrar publishes.
Planning ahead
Enter the grades you expect this term to see where your GPA will land, and try a few scenarios: what if Calculus ends up a B instead of a B+? This helps when you're aiming for a GPA requirement, such as for a scholarship, the dean's list, a major, or academic good standing.
Your courses are saved in the link, so you can bookmark the page and come back after finals, or send it to an advisor with the Share button. Your official GPA is the one on your transcript.
Converting percentage grades
If your transcript shows percentages rather than letters, convert each course to a letter first using your school's scale, then enter the letters. On the common scale used across this site, 93% and above is an A, 90–92.99% an A−, 87–89.99% a B+, and so on down to F below 60%.
Frequently asked questions
How do I calculate my GPA?
Multiply each course's grade points by its credit hours, add the results and divide by the total credits. 49 quality points over 14 credits is a 3.50 GPA.
How do I calculate my cumulative GPA?
Multiply your previous GPA by its credits, add this term's quality points, and divide by all credits. 3.20 over 30 credits plus 49 points over 14 credits gives 3.30.
Is an A+ worth 4.0 or 4.3?
Most schools cap it at 4.0, which this calculator uses. Some give 4.3; check your school's scale.
Do pass/fail classes count toward GPA?
Usually not. Leave them out unless your school counts them.
