Return a Calculated Array within Excel

Question

I'm trying to return a calculated array within Excel and was curious if it was possible.

Imagine a table with 3 fields, Fruit, Count, and Cost.

Fruit can appear multiple times. Count is equal to how many were purchased at any given time. Cost is equal to the unit cost per fruit.

If I were to want to know the average amount spent on a specific fruit, I have the formula {=AverageIf(A2:A10, "apples", count*cost)}. Unfortunately, this doesn't work. Sure I can create the formula myself in another row, but I'm trying to avoid this.

Does anyone have a solution?

Answer 1

You can use array formula

=AVERAGE(IF(A2:A10="Apples",B2:B10*C2:C10))

Entered with Ctrl + Shift + Enter

Or

=SUMPRODUCT(--(A2:A10="Apples"),B2:B10,C2:C10)/COUNTIF(A2:A10,"Apples")

This should be in a cell outside of the data area.
