Excel averageifs with or function

Question

I am using the averageifs function, and have one column where I need to calculate the average if either of the criteria are true.

I have tried using the OR function,

Answer 1

AVERAGEIFS extra criteria is a boolean AND operator, it can't perform OR operations. But since your columns do not change we can somewhat implement this ourselves:

Here is a simple way using an array formula (entered with ctrl + shift + enter):

=AVERAGE(IF((I1:I612="IF")+(I1:I612="FL"),N1:N612))

Or if you don't like using array formulas you basically do this manually using SUMPRODUCT and COUNTIF:

=SUMPRODUCT((I1:I612="IF")*(N1:N612)+(I1:I612="FL")*(N1:N612))/(COUNTIF(I1:I612,"IF")+COUNTIF(I1:I612,"FL"))
