Weighted average calculation

How to calculate weighted average?

To calculate the weighted average, you need the values and their corresponding weights. Our calculator makes it easy! For manual calculation, follow these steps:

  1. 1. Make sure you have the values and their corresponding weights.
  2. 2. Multiply each value by its corresponding weight.
  3. 3. Sum all the products.
  4. 4. Sum all the weights.
  5. 5. Divide the sum of products by the sum of weights.

Formula for calculating weighted average

Weighted Average = (value1 × weight1 + value2 × weight2 + ... + valueN × weightN) / (weight1 + weight2 + ... + weightN). Where value1, value2 to valueN are the individual values, weight1, weight2 to weightN are the corresponding weights, and N is the number of values.
