About the GPA Calculator
Your grade point average (GPA) is a weighted average of every grade you've earned, where each course counts in proportion to its credit hours. A 4-credit course pulls your GPA more than a 1-credit course does, which is why two students with the same letter grades can end up with different GPAs if their course loads were weighted differently.
This calculator uses the formula every US registrar uses in some form: add up each course's grade points (on the 4.0 scale) multiplied by its credit hours, then divide by the total credit hours across all your courses. Enter every course from a single term for a semester GPA, or every course you've ever taken for a cumulative GPA — the math is the same either way.
This is an unweighted calculation: it doesn't add bonus points for honors, AP, or IB courses the way some high schools' official weighted scales do, and it uses the standard +/- 4.0 point values rather than any institution-specific variation. Treat the result as a reliable estimate, and check your school's own published scale if you need an exact official figure.
Calculated using the standard credit-hour-weighted GPA formula on the common US unweighted 4.0 scale (A=4.0 through F=0.0, with standard +/- increments). Grading scales vary by institution — check your school's registrar for your exact official scale.
