About this tool
This page opens the grade calculator in weighted average mode with three grades already entered: 88% weighted at 30%, 92% weighted at 30%, and 79% weighted at 40% — a typical midterm, project and final exam split — and the average is computed automatically on load.
The arithmetic is a straight weighted sum: (88×30 + 92×30 + 79×40) / (30+30+40) = 8,560 / 100 = 85.6%. Notice how the 79% pulls the average down more than a simple, unweighted mean of the three scores (86.3%) would suggest, precisely because it carries the largest weight — the component with the biggest share of the grade has the biggest say in the outcome.
The calculator accepts up to five grade-and-weight pairs and does not require the weights to add up to 100 — raw point values from a syllabus work just as well as percentages. Replace the three example pairs above with your own homework, quiz, midterm and project scores to reconstruct your actual course grade.
Example. A current grade of 80, a desired grade of 85, and a final worth 50 percent requires a final score of 90.
Limit. Weighted-average mode accepts at most five grade and weight pairs.
