What is the GPA Calculator?

Your GPA is a single number that quietly follows you into scholarships, applications and internships — and working it out by hand, weighting every course by its credits, is fiddly enough that most people just guess.

This GPA calculator does the weighting for you: enter your courses, credits and grades, and see your grade point average on the 4.0 scale instantly.

What does this tool do?

You add each course with its credit hours and letter grade, and the calculator converts grades to points and weights them by credits.

It shows your GPA on the standard 4.0 scale along with your total credits, updating live as you edit.

Common mistakes to avoid

Ignoring credit hours

Fix: A 4-credit course affects GPA more than a 1-credit one — enter credits correctly.

Averaging letter grades directly

Fix: Convert to points and weight by credits; a plain average is wrong.

Including pass/fail courses

Fix: Most schools exclude them from GPA — leave them out.

Mixing scales

Fix: Stick to one scale (usually 4.0) across all courses.
