How we calculate it
Each letter grade is converted to grade points (A = 4.0, A− = 3.7, B+ = 3.3, B = 3.0 and so on down to F = 0). Each course’s points are multiplied by its credit hours, the products are added and the total is divided by the total credits.
This calculator uses the common plus/minus 4.0 scale. Some schools do not award an A+ above 4.0 or use different values for minus grades.
How to read your result
- GPA is total quality points divided by total credits, where an A is 4.0, a B is 3.0 and so on.
- Credits weight the average: a 4-credit course counts more than a 1-credit course.
- Plus and minus grades change the points (an A- is 3.7, a B+ is 3.3). Check your school’s scale.
- The weighted GPA calculator adds half a point for honors and a full point for AP or IB classes.
Common mistakes
- Entering letter grades but leaving credits blank. A course with no credits is not counted.
- Using a weighted scale when your school reports an unweighted GPA, or the other way around.
- Forgetting that pass/fail courses usually do not count toward GPA.
- Averaging semester GPAs instead of weighting by credits, which gives the wrong answer when credit loads differ.
Assumptions and limits
- Check your school’s grading scale. Some use 4.3 for A+ or have no plus and minus grades.
- Pass/fail and withdrawn courses are usually excluded from GPA. Leave those rows blank.
- For honors or AP courses, use the weighted GPA calculator.
Frequently asked questions
How do I calculate my cumulative GPA?
Enter every course you have taken with its grade and credits. If you have more than eight, combine them or calculate in two batches by multiplying each batch’s GPA by its credits and dividing by total credits.
What is a good GPA?
A 3.0 is a B average. Many scholarships and programs look for 3.5 or higher, but requirements differ widely.
Do all credits count the same?
No. A 4-credit course affects your GPA more than a 1-credit course because grade points are weighted by credits.
