GPA Calculator

Each letter grade maps to grade points: A = 4.0, A- = 3.7, B+ = 3.3, B = 3.0, and so on down to F = 0.0. Multiply each course's points by its credit hours to get quality points, add them all, and divide by the total credits: GPA = total quality points ÷ total credit hours So an A (4.0) in a 4-credit class and a B (3.0) in a 2-credit class give (4.0×4 + 3.0×2) ÷ 6 = 3.67.

A plain average of your letter grades ignores that a 4-credit course counts more toward your standing than a 1-credit one. Credit weighting fixes that — a strong grade in a heavy course lifts your GPA more than the same grade in a light one. Leave the credits blank and this calculator weights every course equally instead.

This uses the standard unweighted 4.0 scale. Some high schools use a weighted scale that gives honors and AP courses up to 5.0, and a few colleges use pluses and minuses differently (A+ above 4.0, or A/A- collapsed). Check your institution's exact scale — the method here is the common one, but the point values can vary.
