Calculating a credit-weighted GPA
A grade point average is not a simple average of your grades, it weights each course by its credit hours, so heavier courses count for more. This calculator takes up to five courses and produces the weighted result.
Seeing the GPA update as you enter grades makes it clear why the high-credit courses deserve the most attention.
How to use this calculator
- Choose a letter grade for each course from the dropdown.
- Enter the credit hours for each course.
- Leave unused rows blank; read your weighted GPA.
What the inputs mean
- Grade
- Mapped to grade points on a 4.0 scale, where A is 4.0 and F is 0.
- Credits
- The credit hours for the course. Heavier courses move the GPA more.
A five-credit B (3.0) and a one-credit A (4.0) give (15 + 4) ÷ 6 = about 3.17, pulled down by the heavier B.
The formula, in plain terms
GPA is the sum of each grade's points times its credits, divided by the total credits.
Frequently asked questions
