End up with the same totals -it is not adding the differnce of each calculation
example:
if a consumption is 22000
per = 99.75
additonal
should be a total of 105.00

formula produces 115.50

I am trying to calculate a progressive rate for water use charges:
<8500=$40,
8501 up to /1000
21000 up to /1000
50000 @6.00/1000

Col.A lists consumtion in gallons
is there a formula I can use for this?
