Hi there,

I want to simplify an excessively long nested IF(OR formula; can anyone help?

Here is the formula:
=IF(OR(I$6=$F15+$H15,I$6=$F15+$H15*2,I$6=$F15+$H15*3,I$6=$F15+$H15*4,I$6=$F15+$H15*5,I$6=$F15+$H15*6,I$6=$F15+$H15*7,I$6=$F15+$H15*8,I$6=$F15+$H15*9,I$6=$F15+$H15*10),1,0)

I have attached a screenshot of what I'm trying to do. I am building a rent forecast model, and want to apply inflation. However, inflation could be every 2 years, or every 3 years etc. as specified. My formula only applies CPI after the start year, and then applies CPI at the frequency specified. However, I would need 20 or more OR formulas for my formula to forecast out 20+ years, but I'm sure there is a more graceful and compact formula to do the job. I'm just not sure how to do it.

Appreciative of anyone's help. Thanks very much

Links? Where??
If Excel says you have links but you can't find them, go to Formulas, Name Manager. Look for old links to dead workbooks & delete.
