Excel formula to apply variable percentages
Hi I need a formula to apply to a cumulative income total which calculate percentages of the total based on its value as follows:- 0 to £5,814 - 0% £5,815 to £23,225 - 100% £23,226 and over - ...
When I'd use the column with % change compare to previous range
with formula
=SUMPRODUCT((B8-$E$2:$E$4)*$G$2:$G$4*(B8>$E$2:$E$4))
Thanks - sorry i may not have explained. The percentages are in bands - so if the income is £5,000 i want it to show zero. Once it gets past, £5,814 its 100% of the amount over £5,814. So when its £7,200 it should only show £1,386. I think its a few ifs as :-
If less than £5,814 then zero.
100% of everything between £5,815 and £23,225
80% of everything over £23,226
So the result will be all three added together ( I know the first result will always be nil)
Thanks
