Do you really need a lookup table? In your case the numbers seem to be
straight multiplications by 500.
Your $1800 dollars would be =$1800/(3*$500) which would give 120%.
If you want to round to the nearest 25% you could use
=MROUND(1800/3/500,25%) or if you want to round up you could use
=CEILING(1800/3/500,25%).
Naturally the relevant values in the formula could use cell references as
appropriate.

I want to create a table with income figures and then look up values based
on
household size that is calculated and then return the column lable. For
instance, a 4x4 table with family size 1, 2, 3, 4 and column lables of
100%,
125%, 150% and 175%. The grid is filled with income amounts at each
intersection.

100% 125% 150% 175%
1 500 625 750 875
2 1000 1250 1500 1750
3 1500 1875 2250 2625
4 2000 2500 3000 3500

I want to look up an income amount for a calculated household size (using
a
count function), and return the column lable to show the percentage, so
that
a household of three with income of $1800 will return a value of 125%
