I hope this is ok for you and it does explain. What I am after is if the value of sales is 13,000, I am trying to get the 40% and 45% tax correct. I want the sales value between 3142 and 12500 to input that figure in the cell, say C20 and then over the 12,500 45% to put that value in the C 21, allowing for the difference for the allowance over 100,000. I have a formula for the total tax which is
=MAX(MAX(B1-150000,0)*0.45+MIN(MAX(B1-50270,0),150000-50270)*0.4+MIN(B1-12570,50270-12570)*0.2+MAX((MIN(B1,100000+12570*2)-100000)/2,0)*0.4,0). I want to breakdown each tax percentages for 20%, 40% and 45%. I can upload an excel spreadsheet if required.
