GPA calculator
Type a course, pick its letter grade and its credits. The GPA updates as you type, and the working is under the table.
| Course | Grade | Credits | Remove |
|---|---|---|---|
Add a course, its grade and its credits to see your GPA.
How to use it
- Step 1Type a course in the first column — the name is only for you, so "Bio" is enough — and pick the letter grade you got.
- Step 2Put in how many credits, units or hours the course is worth. Most college courses are 3 or 4; a high school year-long course is usually 1.
- Step 3The GPA appears as soon as one row has both a grade and its credits. Open "How it adds up" to see every step of the arithmetic.
How a GPA is worked out
A GPA is an average of your grades, but not an average of the letters — it is an average of grade points, weighted by how much each course counts. Every letter is worth a number on the 4.0 scale: an A is 4.0, a B is 3.0, a C− is 1.7. That number is multiplied by the credits of the course, which gives what registrars call quality points. Add the quality points up, divide by the credits, and that is the GPA.
The credits are the reason two students with the same letters can have different GPAs. A four-credit A and a one-credit C average to 3.6, not to 3.0: the four-credit course carries four times the weight in the sum.
| Letter | Grade points | Usual percentage |
|---|---|---|
| A / A+ | 4.0 | 93 and above |
| A− | 3.7 | 90–92 |
| B+ | 3.3 | 87–89 |
| B | 3.0 | 83–86 |
| B− | 2.7 | 80–82 |
| C+ | 2.3 | 77–79 |
| C | 2.0 | 73–76 |
| C− | 1.7 | 70–72 |
| D | 1.0 | 63–66 |
| F | 0.0 | under 60 |
What counts, and what quietly does not
Not everything on a transcript reaches the GPA. Pass/fail and credit/no-credit courses normally bring credits but no grade points, so leaving them out of the table is the right thing to do. Withdrawals marked W usually count for nothing at all. Transfer credits often bring the credit hours without the grade, which raises the credits you have earned without moving the average.
Schools also differ at the top and the bottom of the scale. Many count an A+ as 4.0, as this page does; some give it 4.3, which is the only way a GPA on an unweighted scale can be above 4.0. A few schools do not use minus grades at all. If yours is one of them, the table still works — pick the letter your transcript prints.
A repeated course is the case worth checking in your handbook. Some schools replace the old grade, some average the two attempts, and some leave both on the transcript and count both.
Questions and answers
How do I calculate my GPA by hand?
Turn each letter into its grade points, multiply by the credits of the course, add those products up, and divide by the total credits. An A (4.0) in a 3-credit course and a B (3.0) in a 4-credit course give 12 + 12 = 24 quality points over 7 credits, which is 3.43.
What is a good GPA?
It depends entirely on what it is for. A 3.0 is the usual floor for staying in good standing and for many scholarships; 3.5 and above is what competitive graduate programs and internships tend to look for; below 2.0 is where academic probation usually starts. Your own school's handbook is the only place with the real numbers.
Does this work for high school as well as college?
Yes. The mathematics is the same; the difference is that high school courses are usually worth one credit each, so the GPA ends up close to a plain average of the letters. If your school gives extra points for honors and AP classes, use the weighted GPA calculator instead.
Do semester grades count toward my GPA?
The grade that counts is the final grade for the course, the one printed on the transcript. Mid-semester and quarter grades feed into that final grade but are not averaged into the GPA themselves.
