HELP on IF Statement

[Divablair]

=IF('Quarterly Data'!C351> Goals!$Q$45,0,(IF('Quarterly Data'!C395=0,"N/A",(IF((('Quarterly Data'!C351/Goals!$Q$45)-1)=(-1),(100),(ABS(('Quarterly Data'!C351/Goals!$Q$45)-1))*100)))))

Could someone tell me what the -1, (100) is?

So when I calculate the formula (131.511 / 206.076653) I get .6381 then when I take that number and -1 I get 0.3618 *100 for 36.18

Why do we -1? why wouldn't you take .6381*100 for 63.81?


I am just trying to understand why it was written like this so I can verify numbers in a spreadsheet.

Hi @Divablair,
The if statements are working from left to right and depending on the results the -1 will come in to play. So, the first part 'Quarterly Data'!C351> Goals!$Q$45,means that if this is true then the cell displays 0. If that case is false, then the next if statement kicks in. I would say that based on the first statement, the formula is measuring the amount missed of the goal versus the percentage met. So 100% made would display as 0% missed. I think that answers the question here, but I will continue to explain the logic in the following if statements.

The next statement is if quarterly data is 0 to start with which results to "n/a". I would have this statement first in the nested if situation, but that's just preference. The third if isolates the scenario to if quarterly date/goals -1 equals -1. I believe this is redundant to the 2nd if because if quarterly data = 0 then the result would be -1. I think you can remove that third if statement because that scenario wouldn't occur. The final if statement is only in play if the first three are already false which means that only certain conditions are remaining for the calculation to work. The final if is used to display the amount of miss versus the amount made. It only is true if the quarterly data is less than goal and is greater than 0.
