One way:

=LOOKUP(B8,{0,0;3001,0.05;5001,0.075;20001,0.20})

This assumes that $3000 gets $0, but jumps to 7.5% at 3001 ($225.08).

If the rates should apply only to the differential amounts, see

Hi, I am still very much an Excel novice, barley finding my way, so please be
a little patient. I am trying to calculate a commission payment based on a
sliding percentage scale.

Lets say cell B8 contains a salespersons total monthly gross profit, I want
to show their commission payment in cell D5

I require a formula which will calculate if the figure in B8 is less than
$3000 then 0% of the value of B8 will be calculated and shown in D5.

If between $3001 and $5000 then 5% will be shown in D5

If between $5001 and $7500 then 7.5% will be shown in D5

Etc, etc, up too anything over $20000 will be calculated at 20%

All calculations are retrospective to $1

I have tried creating cells H15:H23 with the different percentage amounts in
each but so far to no avail. Any assistance would be greatly appreciated.

=(B8)<30015000*$H$15,(B8)<50017500*($H$17),(B8)< 750110000*($H$18),(B8)<1000
112500*($H$19),(B8)<1250114999*($H$21),(B8)<1500 0*($H$23)

This is just one example of many, many, many, hours of frustration. Have
also tried the=IF true false thing!
