Grade Percentage Calculator

Calculate test percentage, missed points, and letter grade estimate from points earned and total possible points.

What this calculator answers

The grade calculator converts points earned and points possible into a percentage. It can also show how many points were missed and a common letter-grade estimate.

Class policy matters

Teachers and schools may use weighted categories, curves, dropped assignments, late penalties, or custom grade bands. Use the result as a quick estimate unless your syllabus uses the same scale.

Useful study workflow

After a test, compare the points missed with the topics covered. The percentage tells you the outcome, but the missed questions tell you what to review next.

Planning note

For final grades, calculate each assignment category separately if the class uses weights. A simple points percentage may not match the official gradebook.

How to use it

Enter points earned and total points possible.
Review percentage, points missed, and letter estimate.
Check the class syllabus before treating the estimate as final.
