GPA Calculator
Calculate your grade point average from course grades and credit hours.
GPA is a credit-weighted average, not a simple one: an A in a 4-credit course moves your GPA more than an A in a 1-credit seminar. That weighting is exactly what makes it awkward to compute in your head, especially across a full semester of courses with different credit values.
Add each course with its letter grade and credit hours, and this calculator computes your weighted GPA on the standard US 4.0 scale, showing total credits and grade points. Use it to project a semester result, check what you need to hit a target, or verify a transcript.
