GPA Calculator
Enter each course's letter grade and credit hours to get your grade point average on the standard US 4.0 scale — weighted by credits and updated as you type.
How to use
Add a row per course, choose the letter grade (A+ to F) and enter the credit hours. Your GPA and total credits update instantly at the bottom.
Grades are weighted by credits, so a heavier course affects your GPA more. Add or remove rows to model a future semester and see how a grade would change your average.
FAQ
How is GPA calculated?
Each letter grade maps to points (A=4.0, B=3.0, …). Multiply each course's points by its credits, add them up, and divide by total credits — that's your weighted GPA.
What scale does this use?
The standard US 4.0 scale with pluses and minuses (A+/A=4.0, A-=3.7, B+=3.3, and so on down to F=0.0).
Can I calculate a target GPA?
Add hypothetical courses with the grades you expect to see the resulting average — handy for planning what you need next semester.
