Grade Calculator
Calculate your weighted average or points-based grade instantly. Three levels — from a quick check to a full gradebook with statistics.
How to Use This Calculator
Enter each assignment or category with its score and weight above. Your weighted grade updates instantly. Use the Points tab when your class adds up raw points rather than percentages.
The Advanced tier below adds category tracking with bar charts, class-type presets (heavy exam weight, project-based, lab courses), and a grade target planner that tells you exactly what average you need on remaining work. The Professional tier gives you a full gradebook with per-assignment breakdown, statistical analysis, multi-class GPA tracking, and a custom grade scale editor.
Weighted Average Formula
The weighted average assigns more influence to high-weight items like a final exam than to a daily quiz.
Example: (88×0.20 + 79×0.25 + 85×0.15 + 94×0.15 + 82×0.25) ÷ 1.00 = 84.45%
Grade Target Formula
To find the score needed on remaining work to hit a target grade:
Example: Target 90%, completed 75% of weight at 84% avg, 25% remaining
Needed = (90 × 100 − 84 × 75) ÷ 25 = (9000 − 6300) ÷ 25 = 108% (need extra credit!)
