Calculate a weighted average grade from scores and weights
Enter percentage scores and matching nonnegative weights. Weights need not total 100; the result is normalized to their sum.
How to use the Grade Calculator
Calculate a weighted course grade from scores and their percentage weights.
- Enter each score and percentage weight.
- Verify the grading scheme.
- Calculate the weighted total.
Grade Calculator formula
Weighted grade = sum(score × weight) ÷ total weight.
Worked example
Inputs: 90 at 40%, 80 at 30% and 70 at 30%.
What to expect: The weighted grade is 81%.
How to read your result
A high score with a larger weight affects the total more than a small assignment.
