About Gradeline

Gradeline offers free calculators for students: GPA, weighted GPA, class grades, final exam scores and percentages. They run in your browser and need no account.

Why it exists

Grade math is simple, but it is easy to slip on the weights and credits. These calculators show the formula and a worked example so you can check the result yourself.

Who runs it

Gradeline is built and maintained by Luis Insuasti, a software developer. The formulas are standard and are written out on each page. Notes on assumptions are on the methodology page.

What we can and cannot tell you

Schools set their own scales, rounding and rules. Results are estimates. Your school's official record decides.
