How is GPA calculated on the 4.0 scale?

Each letter grade is worth a number of grade points: A is 4.0, B is 3.0, C is 2.0, D is 1.0 and F is 0, with pluses and minuses in between. Multiply each course by its credits, add those up, then divide by the total credits. That credit-weighting is why a higher-credit course pulls your GPA more than a one-credit elective.

What grade points do plus and minus grades use?

This calculator uses the common scale where A- is 3.7, B+ is 3.3, B- is 2.7, and so on, while A and A+ both count as 4.0. Some schools cap A+ at 4.0 and others award 4.3, so check your institution if a fraction of a point matters for you.

What is the difference between weighted and unweighted GPA?

This tool gives a credit-weighted GPA, where courses worth more credits count more. A separate idea, common in US high schools, is weighting for course difficulty, where honours or AP classes are graded on a 5.0 scale. This calculator uses the standard 4.0 college scale and weights by credit hours, not by difficulty.
