Weighted Average Calculator

Calculate the weighted average based on the entered school grades or numbers and their weights.

Enter your values ​​(e.g. school grades) with their weights:
Result:

This calculator allows you to calculate the average of values ​depending on their weights.

The greater the weight of a value, the greater the impact it will have on the final average.

In this tool, you can add any number of values and their respective weights. Besides calculating the weighted average, it also provides the total sum of all weights, shows the entire calculation process, and generates a link for saving or sharing your results.

How to calculate the Weighted Average?

To calculate a weighted average, sum up each number multiplied by its weight.

Then divide the result by the sum of all weights.

Math Formula

Weighted Average = (v1 * w1 + v2 * w2 + ...) / (w1 + w2 + ...)
Where:
  • v = Value
  • w = Weight

Example

Calculate the weighted average for the numbers: 3, 2, 4 with weights: 5, 4, 1.
(3 * 5 + 2 * 4 + 4 * 1) / (5 + 4 + 1)
= (15 + 8 + 4) / 10
= 27 / 10
= 2.7
