Enter the values ​​(e.g. school grades) and their weights:
Result:

Weighted Average allows you to calculate average of values ​​with different weights. The greater is the weight of a value, the greater the impact it will have on the final average.

How to calculate Weighted Average?

To calculate a weighted average, add together each number multiplied by its weight. Then divide the obtained result by the sum of all weights.

  • x = Value
  • w = Weight
Weighted average = (x1 * w1 + x2 * w2 + ...) / (w1 + w2 + ...)

Example

Calculate the weighted average for the numbers: 3, 2, 4 with weights: 5, 4, 1.

Weighted average:

(3 * 5 + 2 * 4 + 4 * 1) / (5 + 4 + 1)
= (15 + 8 + 4) / 10
= 27 / 10
= 2.7
