using IF function to retrieve output values from a table given an input value

Goal: For T4, use the value of H3/H4 as the size factor to find the cost multiplier in B4:B21 on tab "RSM Index."

Not sure mathematically how this works, but I think it would be

<.5 = 1.1
>=.5 and <.525 = 1.09
>=.525 and <.575 =1.08
>=.575 and <.625 =1.07

Etc

Thank you!!

You need to change the entry in cell A4 of the RSM Index sheet to zero, then you can use this formula in T4:

=VLOOKUP(H3/H4,'RSM Index '!$A$4:$B$20,2)

Note that row 21 of the RSM Index sheet is not needed. Note also that you have a space at the end of the tab name for that sheet.

Hope this helps.

Pete - thanks for that. I realize I have to tweak the input a little but I think this will work well.

Cheers

Glad to help.
