Calculating a weighted average using Excel Functions A retail price index would take this into account and use a weighted average which gives more prominence to commonly bought items. Excel does not contain a built in function to calculate a weighted average. It is however easy to do it using the SUMPRODUCT() function in a simple formula. SumProduct() multiplies two arrays (or ranges) together and returns the sum of the product. In the illustration it would calculate '(B4 x C4) + (B5 x C5) + (B6 x C6)'.

Weighted Average The weighted average formula is used to calculate the average value of a particular set of numbers with different levels of relevance. The relevance of each number is called its weight.The weights should be represented as a percentage of the total relevancy.owever, the weighted average formula looks at how relevant each number is. Say that 1 only happens 10% of the time while 2 and 3 each happen 45% of the time. The percentages in this example would be the weights.

Weighted Mean Mean = ¼ × 1 + ¼ × 2 + ¼ × 3 + ¼ × 4 = 0.25 + 0.5 + 0.75 + 1 = 2.5. Same answer. Now let's change the weight of 3 to 0.7, and the weights of the other numbers to 0.1 so the total of the weights is still 1: Mean = 0.1 × 1 + 0.1 × 2 + 0.7 × 3 + 0.1 × 4 = 0.1 + 0.2 + 2.1 + 0.4 = 2.8. This weighted mean is now a little higher (pulled there by the weight of 3).
