In the above case, the weights were assigned in such a way that the total added up to 100%. Here is an illustration to make it clear.Įxample 2 – When Weights Don’t Add Up to 100% Then it multiplies the second element of the first array with the second element of the second array. Here is how this formula works : Excel SUMPRODUCT function multiplies the first element of the first array with the first element of the second array. Here is the formula that will give you the weighted average in Excel: =SUMPRODUCT(B2:B8,C2:C8) In such a case, you can use the SUMPRODUCT function to get the weighted average of the score. A simple average can not be calculated here as the importance of different evaluations vary.įor example, a quiz, with a weight of 10% carries twice the weight as compared with an assignment, but one-fourth the weight as compared with the Exam.

In the above data, a student gets marks in different evaluations, but in the end, needs to be given a final score or grade. Suppose you have a dataset with marks scored by a student in different exams along with the weights in percentages (as shown below): Below are three different situations where you can use the SUMPRODUCT function to calculate weighted average in Excelīelow are three different situations where you can use the SUMPRODUCT function to calculate weighted average in Excel Example 1 – When the Weights Add Up to 100% There could be various scenarios where you need to calculate the weighted average.
