Weighted Average Calculator
Combine values and weights into a single weighted mean.
Averages that respect importance
A plain average treats every value equally, but often some matter more — a final exam over a quiz, a large holding over a small one. A weighted average multiplies each value by its weight before averaging.
Values of 90, 80, and 70 with weights of 3, 2, and 1 give a weighted mean of about 83.3, pulled toward the heavily weighted 90. Enter your values and matching weights to compute it instantly.
