863732 2010-03-03 20:36:00 Could some one help please with a formula to change a total cost which includes gst to a total with gst excluded.
Could do it in 2 formulas I suppose divide by 9 then subtract from total can it be done in one formula?

Thanks

863733 2010-03-03 21:06:00 11.25 =A1-(A1/9) (result = "10")

(where the value "11.25" is in cell A1)

863734 2010-03-03 21:26:00 Correct answer.

A1/9 is evaluated first then subtracted from the original A1.

Doing a spreadsheet for a mate who has a franchise saw him with calculator and paper will take him days. By entering in xcel sheet should take an hour at most
The franchise has a 3month period for every 1000 excl gst you spend with him goes into 4 prizes to go to Gt Barrier reef with top Oz fisherman.
His report on cashbook has gst price and needs to enter invoice numbers which have to be printed and sent as proof to franchise hq.

Thanks

Column A is the number you need to change
Column B is the formula, which is =SUM(A1/9)*8

If you enter A1 as 11.25, the result in B1 will be 10.00
If you enter A2 as 112.50, the result in B2 will be 100.00

Note as you drag the formula in B1 down, it automatically changes A1 to A2 etc)

I'm all for that. And as mine is the most unwieldy of the replies, naturally I would have first right of refusal. :p

Just a small question why 11.25 when gestapo is 12.5% remember you are talking to a thicky here.
prefect (6291)
863741 2010-03-04 01:32:00 12.5% of 10 = 1.25
10+1.25 = 11.25
