What if weights don't add to 100?
The calculator handles this automatically by dividing by actual total weight. Your grade is still accurate based on relative importance.

Weighted Grade Calculator
Calculate your final grade with weighted assignments.
Precise Grade Analysis
Factor in assignment weights to understand your exact standing and plan your academic strategy.
What this calculator does
The Weighted Grade Calculator determines your final course grade when different assignments count for different percentages. It multiplies each score by its weight and sums them for your weighted average.
How it works
Enter up to four scores and their corresponding weights. The calculator multiplies each score by its weight, sums weighted scores, then divides by total weight for your final weighted grade.
Formula
Weighted Grade = (Score1 × Weight1 + Score2 × Weight2 + ...) ÷ (Weight1 + Weight2 + ...). Weights can be percentages or decimals.
Tips for using this calculator
- Check your syllabus for exact weights
- Enter current scores before all assessments complete to see what you need
- If weights are points instead of percentages, use those directly
- Update throughout the semester to track progress
- Some courses allow extra credit—enter as additional small-weight assessments
Frequently asked questions
How do I enter point-based weights?
Use point values directly as weights. If homework is 100 points and exam is 200 points, enter weight1=100, weight2=200.
Can I work backward to find needed scores?
Yes, manually adjust scores until you reach your target, or use algebra: (Target × Total Weight − Other Weighted Scores) ÷ Remaining Weight.
