How do I calculate my GPA?

Enter each course grade and credit hour. The calculator multiplies grade points by credits, sums them and divides by total credits to compute weighted GPA.

Can I use numeric and letter grades?

Yes. You can type a numeric grade (0-100) or a letter (A, A-, B+, etc.). The tool converts letters to grade points using a common scale.
