Weighted Average Calculator
The Weighted Average Calculator computes the mean when different values contribute unequally to the final result. Unlike a simple average, each value is multiplied by its weight before summing. This is essential for GPA calculations (credit hours as weights), portfolio returns (investment sizes as weights), and any scenario where some values matter more than others.
How to Use This Calculator
- 1
Enter each value and its corresponding weight.
- 2
Use 0 for weight to exclude optional values 4 and 5.
- 3
Click Calculate — the result is the weighted mean.
