Here's an example to check out: Sheet =AVERAGE(OFFSET([@Amount],-2,0,3,1)) However, that would fix the number of months within the formula, and, since we want to make it easy for the user to change the number of months in our average, we store the months value in cell C5, and then update our formula as follows. =AVERAGE(OFFSET([@Amount],-($C$5-1),0,$C$5,1)
