GPA Calculator

A GPA isn't a simple average of your grades — a 3-credit class and a 4-credit class don't count equally, and most people only remember that fact right when they're staring at a transcript trying to figure out where they actually stand. This calculator does the credit-weighted math directly: list each course's credit hours and the grade point it earned, and it works out the overall average the way a registrar's office would.

It's most useful at the two ends of a semester — planning what GPA a set of expected grades would produce before finals, and double-checking an official transcript figure once grades post. Transfer students and applicants comparing schools with different course loads use it too, since it's the credit weighting, not just the letter grades, that determines the final number.

Grade points here follow the standard 4.0 scale (A = 4.0, B = 3.0, and so on, with pluses and minuses typically landing at .3 or .7 increments) — check your specific school's scale before relying on the result, since a few institutions use a 4.3 or 4.5 scale instead.

Each course's credit hours are multiplied by its grade point to get that course's "quality points." The quality points for every course are summed, then divided by the total credit hours across all courses — GPA = Σ(credits × grade point) ÷ Σcredits. A 4-credit A (4.0) contributes more to the total than a 1-credit A, which is exactly why credit weighting matters.
