GPA Calculator
Add each course with its credits and letter grade and watch your GPA update as you type. It handles plus/minus grades, runs in your browser, and nothing you enter is stored or sent anywhere.

How to use the GPA Calculator
- Choose your grading scale. Most US colleges use the standard 4.0 scale with plus/minus grades — pick “letters only” if your school does not award A− or B+.
- Enter the credits (credit hours) and the letter grade for every course. Leave unused rows empty.
- Read your GPA, the credits counted and the line-by-line breakdown. Use “Add course” for more rows or “Load example” to see a worked case.
How GPA is calculated
Your grade point average is a weighted average. Every letter grade is turned into grade points, multiplied by the course’s credits to give quality points, and the quality points are divided by the total credits:
GPA = Σ (grade points × credits) ÷ Σ credits
Here is a small example with three courses:
| Course | Credits | Grade | Grade points | Quality points |
|---|---|---|---|---|
| Calculus | 3 | A | 4.0 | 12.0 |
| Biology | 4 | B+ | 3.3 | 13.2 |
| History | 3 | C | 2.0 | 6.0 |
| Total | 10 | 31.2 |
31.2 ÷ 10 = 3.12. A heavier course moves your GPA more than a light one: the 4-credit B+ counts more than the 3-credit A.
The standard 4.0 grade-point table
| Letter | Points | Letter | Points |
|---|---|---|---|
| A+ | 4.0 (4.3 on some scales) | C+ | 2.3 |
| 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 |
| F | 0.0 |
This is the most common table at US colleges, but not the only one. A few schools give an A+ 4.3 (choose the 4.3 scale above), some do not use plus/minus grades at all, and some use different values for A− or D. If your transcript or student handbook publishes its own table, trust that one.
Semester GPA vs. cumulative GPA
A semester GPA uses only the courses of one term. Your cumulative GPA covers every course you have taken. To see how a new term changes your overall number, use the cumulative GPA calculator; to plan how much you must earn in the future, use the target GPA calculator.
What this calculator ignores
Rows with no credits or no grade are skipped, so pass/fail, withdrawn (W) and incomplete (I) courses do not affect the result — which matches how most schools treat them. Policies that differ between schools, and that you may need to apply by hand, include:
- Repeated courses — some schools replace the old grade with the new one, others average both. Delete the attempt that your school does not count.
- Transfer credits — usually count toward your degree but not your GPA.
- Rounding — schools publish GPAs to two or three decimals; the result card shows both.
Frequently asked questions
What is a good GPA?
It depends on your goals. Many scholarships and employers use 3.0 as a cut-off, a dean’s list often starts around 3.5, and competitive graduate programs usually expect a bit higher. Check the requirement of the specific program you care about.
Do I need credits to calculate my GPA?
Yes, because courses are weighted by credits. If your school counts every course equally, enter 1 credit for each one.
How are plus and minus grades counted?
In the standard table an A− is 3.7, a B+ is 3.3 and a B− is 2.7. Choose the “letters only” scale if your school does not use plus/minus grades.
Does an F count in my GPA?
Yes. An F is worth 0.0 grade points but its credits still count, so it pulls the average down.
