Try:

=IF(A2<=100,A2*0.15,IF(A2<=200,15+(A2-100)*0.1,25+(A2-200)*0.05))

A2=Sale value

Not I have assumed less than or equal to 100, 200: change if needed

I need a formula to do this: if the sale is less than $100 the commission is
15% of the sale, if the sale is less then $200 the commission is 15% on the
first hundred + 10% of the balance of the sale, and if the sale is over $200
the commission is 15% of the first $100 , 10% of the second $100 and 5% for
anything over $200.

I came up with =IF(D9<100,".15",IF(D9<200,".1","")) which does not come near
to what I need.

I need help, I am using Excel 2002.
