GPA Calculator

This GPA calculator turns your course grades and credit hours into a weighted grade point average on the standard 4.0 scale. Because it weights each course by its credits, a heavier class counts more toward your final number than a lighter one. Enter each course, its grade, and its credit hours to see your cumulative GPA.

How to use the GPA Calculator

1. Add a row for each course you are taking.
2. Select or enter the letter grade for each course.
3. Enter the credit hours for that course.
4. Read your weighted GPA, which updates as you add or change rows.

Frequently asked questions

How is a weighted GPA calculated?

Multiply each course's grade points by its credit hours, add those products, then divide by the total credit hours. The formula is GPA = sum(grade points times credits) divided by sum(credits).

Can you show a worked example?

Say you earn an A (4.0) in a 3-credit class and a B (3.0) in a 4-credit class. That is (4.0 times 3) plus (3.0 times 4), which is 12 plus 12, equals 24, divided by 7 total credits, giving a GPA of about 3.43.

What grade points map to common letter grades?

On a 4.0 scale, A is 4.0, B is 3.0, C is 2.0, D is 1.0, and F is 0.0. Plus and minus grades usually shift the value by about 0.3 (for example, B+ is 3.3 and A- is 3.7).

Why does a weighted GPA differ from a simple average of grades?

A simple average treats every course equally, but a weighted GPA gives more influence to courses worth more credits. A strong grade in a 5-credit course pulls your GPA more than the same grade in a 1-credit course.
