Your GPA is the average of your grade points weighted by credit hours, not a plain average of your grades. A four-credit course moves your GPA more than a one-credit course with the same grade, which is why the two numbers can differ noticeably.

How to use this calculator
- Pick the grading scale your school uses. If you are not sure, the standard 4.0 scale with plus and minus grades is the most common starting point.
- Choose whether you are entering letter grades, percentages or grade points.
- Enter each course, its credit hours and the grade you earned. Course names are optional — they only appear in the breakdown and in anything you copy or save.
- Your GPA updates as you type. Nothing is submitted and nothing is stored unless you sign in and choose to save it.
Leave a row blank if you do not need it. Rows with nothing in them are ignored rather than counted as zeros.
How the calculation works
Every letter grade is worth a number of grade points. On a standard 4.0 scale an A is 4.0, a B is 3.0 and so on. Each course is then worth its grade points multiplied by its credit hours — the result is called quality points.
Your GPA is the total quality points divided by the total credit hours. That division by credits is what makes it a weighted average, and it is the step most hand calculations get wrong.
The GPA formula
In words: multiply each course's credits by its grade points, add those up, then divide by the total number of credits.
A worked example
Suppose you took four courses this semester:
| Course | Credits | Grade | Grade points | Quality points |
|---|---|---|---|---|
| Biology 101 | 4 | A | 4.0 | 16.0 |
| Calculus I | 4 | B | 3.0 | 12.0 |
| English Composition | 3 | B+ | 3.3 | 9.9 |
| Art History | 2 | A- | 3.7 | 7.4 |
| Total | 13 | — | — | 45.3 |
45.3 quality points ÷ 13 credits = 3.48.
Notice what happens if you average the four grades on their own: 4.0, 3.0, 3.3 and 3.7 average to 3.50. The real GPA is slightly lower because the B was worth four credits while the A- was worth only two. Heavier courses pull harder.
Common grade point values
These are the values on the standard 4.0 scale used by many US schools. Yours may differ — check your syllabus or student handbook.
| Letter grade | Grade points | Typical percentage |
|---|---|---|
| A | 4.0 | 93–100% |
| A- | 3.7 | 90–92.99% |
| B+ | 3.3 | 87–89.99% |
| B | 3.0 | 83–86.99% |
| B- | 2.7 | 80–82.99% |
| C+ | 2.3 | 77–79.99% |
| C | 2.0 | 73–76.99% |
| C- | 1.7 | 70–72.99% |
| D+ | 1.3 | 67–69.99% |
| D | 1.0 | 63–66.99% |
| D- | 0.7 | 60–62.99% |
| F | 0.0 | 0–59.99% |
Important notes and limitations
Schools calculate GPA differently
There is no single national GPA formula in the United States. Schools differ on whether plus and minus grades carry separate values, whether an A+ is worth more than 4.0, how pass/fail and transfer credits are treated, and what happens when you repeat a course.
- Pass/fail and transfer credits usually count toward credits earned but not toward your GPA, because they carry no grade points.
- Withdrawals normally do not affect GPA, though a punitive W at some schools does. Check how yours records them.
- Repeated courses are handled differently everywhere — see the Retake GPA Calculator for the three common policies.
- Rounding here is to two decimal places. Some schools truncate rather than round, so a 3.499 may appear as 3.49 on your transcript rather than 3.50.
- This calculator is a planning tool. Your transcript is the authoritative record.
Frequently asked questions
Is GPA an average of my grades?
Not quite. It is an average weighted by credit hours. A three-credit course counts three times as much as a one-credit course with the same grade, so your GPA and a plain average of your letter grades will usually differ.
What is a good GPA?
It depends entirely on what you need it for. Many scholarships and honours programmes look for 3.5 and above, most graduate programmes expect at least 3.0, and many schools require a 2.0 to remain in good standing. Ask your adviser what applies to your situation rather than aiming at a general number.
Does an A+ count as more than 4.0?
Sometimes. Some schools award 4.3 for an A+, others cap every A at 4.0. Both are common. Switch the grading scale above to the A+ option if yours awards 4.3.
Why is my GPA different from the one on my transcript?
The usual reasons are a different grading scale, pass/fail or transfer credits that your school excludes, a repeated course handled under a replacement policy, or truncation instead of rounding. If you have entered everything and the numbers still differ, your registrar can tell you which rule applies.
Do I need an account to use this?
No. The calculator, the breakdown, copying and printing all work without signing in. An account only adds the ability to save a calculation and come back to it.
Can I use percentages instead of letter grades?
Yes — switch the entry mode above. Percentages are converted using the cut-offs published for the selected scale. If your school uses different cut-offs, entering the letter grade directly avoids the conversion entirely.
