Weighted Average Calculator
Calculate the weighted average (weighted mean) of up to 6 values with their corresponding weights. Use for GPA calculations, portfolio returns, grading systems, and more.
The weighted average assigns different importance (weights) to each value.
Formula: Weighted Average = Σ(xᵢ × wᵢ) / Σwᵢ
When weights are equal, the weighted average equals the simple arithmetic mean.
Common Uses:
- GPA (credits as weights)
- Portfolio return (investment amounts as weights)
- Course grades (assignment weights)
- Composite scores
