GPA Calculator
Add a row for each course with its letter grade and credit hours, and this tool calculates your weighted GPA on the standard 4.0 scale used by most US institutions.
How It Works
Each letter grade is converted to a grade point using the standard 4.0 scale. Every course's grade point is multiplied by its credit hours to get quality points. All quality points are added up and divided by the total credit hours to get your weighted GPA.
Some institutions use a slightly different scale or do not award plus and minus grades. Check your school's official policy if you need an exact match.
Worked Example
Take three courses: a 4-credit course with a B+ (3.3), a 3-credit course with an A (4.0), and a 3-credit course with a C (2.0). Quality points: (3.3 x 4) plus (4.0 x 3) plus (2.0 x 3) equals 13.2 plus 12.0 plus 6.0, which is 31.2. Total credit hours: 4 plus 3 plus 3 equals 10. GPA: 31.2 divided by 10 equals 3.12.
Frequently Asked Questions
What grade scale does this calculator use?
It uses the common US 4.0 scale: A = 4.0, A- = 3.7, B+ = 3.3, B = 3.0, B- = 2.7, C+ = 2.3, C = 2.0, C- = 1.7, D+ = 1.3, D = 1.0, D- = 0.7, F = 0.0.
Do all schools use this exact scale?
No. Some institutions round differently, use a different scale entirely, or do not award plus and minus grades. Check your school's official grading policy if you need an exact match to your transcript.
How is weighted GPA different from a simple average?
Weighted GPA accounts for how many credit hours each course is worth, so a 4-credit class affects your GPA more than a 1-credit class. A simple average would treat every course equally regardless of credit hours.
Can I add more than one semester of courses?
Yes. Add a row for every course you want included, regardless of which semester or term it was taken in, and the calculator will average all of them together into one overall GPA.
What if I have a Pass/Fail or an Incomplete course?
This calculator only supports standard letter grades A through F. Pass/Fail and Incomplete grades typically do not count toward GPA and should be left out of the calculation.
