Student & Math Calculators

Everything you need to stay on top of your grades.

The 4.0 scale is a convention. We say so.

Type three courses into the GPA calculator and it multiplies each grade's point value by its credit hours, adds the results, and divides by total credits, the same quality-points math a registrar runs. What most calculators skip: an A+ is worth 4.0 at some schools and 4.3 at others, and an AP class might add a full grade point at your school or half a point at the next one over. Every calculator here states its default and links to the scale page so you can check it against your own transcript before trusting the number.

Why this instead of a generic GPA site

Three things most GPA calculators skip

A convention you can name

Search "GPA calculator" and most results apply a 4.0 scale without saying so. The weighted GPA calculator tells you exactly which honors and AP bonus it used, so you can compare it against your school's own handbook.

Results built to share

Your GPA, your grade-point total, and the score you need on a final all show as a clean number you can screenshot or read off to a parent or advisor, not buried in a wall of text.

Arithmetic you can check

Guides like how to calculate GPA walk the quality-points math by hand with real numbers, so you can verify a calculator's output yourself instead of taking our word for it.
