Weighted Grade Calculator
Calculate a normalized average from differently weighted grades.
Calculate a weighted grade
Enter up to six items. Completely blank rows are ignored.

Combine grades with different weights
Enter up to six grades and their percentage weights. Blank rows are ignored. The calculator reports each contribution, the total entered weight, and a weighted grade normalized across the entered items.
Formula
Contribution points equal grade multiplied by decimal weight. Weighted points are the sum of all contributions. The normalized weighted grade divides weighted points by the total entered decimal weight.
When weights total 100 percent, weighted points and normalized grade are identical. When they total less or more, the displayed weight total signals that the entries represent a partial or nonstandard scheme.
Check the official grading rules
This tool does not implement category caps, dropped scores, missing-work rules, curves, extra-credit policies, or instructor rounding. Use the exact weights and grade definitions from the course materials.
Frequently asked questions
Do the entered weights have to total 100 percent?
No. The calculator normalizes the entered items by their total weight. It also displays the weight total so you can check whether you entered a complete grading scheme.
What are contribution points?
Each grade is multiplied by its decimal weight. When weights total 100 percent, the contribution points add directly to the overall grade.
Why can a normalized grade differ from the contribution points?
When entered weights do not total 100 percent, contribution points represent only that portion of the full scheme. The normalized grade rescales the entered items to compare them as a complete set.
Can I enter extra credit?
Grades up to 200 percent are accepted, but the result may not match a course that caps categories or handles extra credit separately.
