Hi

I have three columns as below

Unit Price ABC Company
Price EFG Company Price
Not Known 40%
discount 30% Discount
Not Known 20%
discount 30% Discount

I am getting a little confused because there seems to be in the Excel
help file different ways to calculate, and I keep getting different
answers!

I need to work out firstly what the Unit price is, and I need to work
it out from the discount given to EFG Company (ie 30%). From that,
once I work out the Unit Price I can work out what I will be selling
my goods at to ABC Company.

My problem is, I have never been good with maths and have been told
that just putting on 30% will not give me a correct answer, I should
use a decimal point ie 0.50 (which I think is 50%) or 0.70 for 30%.
Can someone help me here as I have messed about with this all morning
and got nowhere fast

Thanks

Hi,

Your column formatting got a bit mixed up when pasted in but if you want to
reduce a value by (say) 15% use this formula

=A2*(1-0.15)

Where A2 is the value you want to reduce
Simply change the 0.15 to reduce by other amounts.

You can work with percentages you don't have to use decimals, and it makes
it easier to read.

If the discount is 30%, and the original price is 2.57, then the discounted
price is

=2.57-(2.57*30%)

that is the price - (the price multiplied by the discount). You might want
to round it to 2 dec pl

=ROUND(2.57-(2.57*30%),2)

If the discount is 30% and the discounted price is say 2.99, then the unit
price, rounded, is

=ROUND(2.99/(100%-30%),2)
