How to Calculate Your Grade in a Class
Updated June 2026
Weighted grade from your scores.
Most classes weight categories differently โ tests count more than homework. Here's how to turn those weights into your overall grade.
The formula
Overall = ฮฃ (category average ร category weight)
Multiply each category's average by its weight (as a decimal), then add them all up.
Worked example
Say the syllabus is: Homework 20%, Tests 50%, Final 30%. Your averages are 95, 82, and 88.
- Homework: 95 ร 0.20 = 19.0
- Tests: 82 ร 0.50 = 41.0
- Final: 88 ร 0.30 = 26.4
Add them: 19.0 + 41.0 + 26.4 = 86.4% overall.
A key check
The weights should add up to 100% (or 1.0). If they don't, either the syllabus lists categories you haven't included yet, or you've misread a weight โ double-check before trusting the result.
Points-based classes
If your class grades on total points instead of weighted categories, just divide your earned points by the total possible points. The tool below handles both styles.

Frequently asked questions
What if my category weights don't add up to 100%?
Then a category is missing or mislabeled. All weights should total 100% for the overall grade to be accurate.
How is this different from a points-based grade?
Weighted grades scale each category by importance. Points-based grades simply divide earned points by total points, ignoring categories.
