How GPA is calculated

GPA = total grade points ÷ total credit hours. For each course, multiply the grade point (for example A = 4.0) by the number of credits, add those products, then divide by the sum of credits.

This page uses a common U.S. 4.0 scale with plus/minus grades. Your school may round differently or use a weighted scale for honors or AP classes—check your transcript or handbook for official numbers.

Frequently asked questions about the gPA Calculator

  • How is GPA calculated?

    Multiply each course’s grade points by its credit hours, add those values, and divide by total credit hours.

  • What is a good GPA?

    It depends on your school and goals. Many colleges treat roughly 3.5+ as strong on a 4.0 scale, but programs vary.

  • Weighted vs unweighted GPA?

    Unweighted caps most grades at 4.0. Weighted scales add extra points for honors or AP courses. This tool uses an unweighted 4.0-style scale.
