Assuming your monthly earnings is in A2:

=MIN(3500,MAX(0,(A2-5500))*40%+MIN(A2,3000)*66.7%+MIN(2500,MAX(0,A2-3000))*55%)

Note that the 5500 comes from the sum of your first two conditions. You
could of course replace the cutoff points and percentages with cell
references, if desired.

I can get 2/3 of the formula done, but I'm stumped on the middle section.
Any help is greatly appreciated! I'm trying to calculate a benefit amount
based on earnings, as follows:

66.7% of the first $3,000 of monthly earnings
55% of the next $2,500 of monthly earnings
40% of any balance

The maximum result is $3,500.

Thanks to any and all!
