Compute a weighted average from multiple scores and importance weights (sum(value × weight) ÷ sum(weights)), with a distribution-style chart for usability.

Weighted Average Calculator

Use weights to model importance. Formula: (sum(value × weight) ÷ sum(weights)).

Compute

Weighted average of multiple values

Formula

Weighted Average = (sum(value × weight) ÷ sum(weights))

Frequently Asked Questions

A weighted average is a mean where each value is multiplied by a weight (importance) and then divided by the sum of weights.

Key Terms

Weighted average
An average where each value is multiplied by a weight and normalized by the sum of weights.
Weight (importance)
A multiplier that controls how strongly a value affects the final result.
Total weight
The sum of all weights. It is used to normalize the weighted average.
