About GPACalculator

GPACalculator is a collection of free, browser-based tools for grades: calculate your GPA by course and credit, combine terms into a cumulative average, work with weighted and unweighted scales, and convert between percentages, letter grades and 4.0 points.

Alongside the GPA tools there is a full set of grade calculators — weighted course grades, the score needed on the final exam, grade curves and the easy grader chart teachers use to mark a stack of papers quickly.

Every calculation runs locally in your browser. Your grades, courses and credits are never uploaded, stored or transmitted, there is no sign-up, and nothing is behind a paywall.

The guides explain the arithmetic behind the numbers — how GPA is calculated, what counts as a good GPA, weighted versus unweighted scales and how to raise a GPA realistically — so the results can be checked and applied rather than just trusted.
