How to Calculate the Weighted Average in Google Sheets

If you’re looking to Calculate the Weighted Average in Google Sheets, you have landed at the right place.

First, here’s a quick video featuring both methods:

Now, here’s a detailed explanation of the Google Sheets formula to Calculate the Weighted Average:

#1 – By using SUMPRODUCT function

=SUMPRODUCT(B2:B10,C2:C10)/SUM(C2:C10)

• SUMPRODUCT multiplies the values in columns A and B together, then adds them up.
• The formula then divides this result by the sum of the values in column B.
• This gives the weighted average of the values in column A, where the weights are in column B.

#2 – By using SUM and ARRAYFORMULA function

=SUM(ArrayFormula(B2:B10 * C2:C10))/SUM(C2:C10)

• ArrayFormula allows us to perform operations on arrays of values.
• The formula multiplies the values in columns A and B together as arrays, then adds them up.
• The formula then divides this result by the sum of the values in column B.
• This gives the weighted average of the values in column A, where the weights are in column B.

That’s it.
