Discounted Rate : Errors in Spreadsheet/ Incorrect Outcome Data
	
	
		Hi Guys.
This is my first time here at Askme and I am hoping that you will be able to help.
I am currently trying to make a spreadsheet where I will be able to calculate discounted rate(in a percentage)
This is what I am looking to achieve -
Unit Price     Sold Price       Discount %
250             100               40%
=(Sold Price/Unit Price)*100
However I keep getting incorrect figures when I have figures more than 3 figures 
Unit Price     Sold Price       Discount %
1500           200                13.3%  
Obviousy my discount is not 13%
And Finally - when I input the following example
Unit Price    Sold Price     Discount %
250            250              100%
Is there anyway that I can sound proof this formulae which will take into consideration what I am trying to achieve?
Thank you in advance for any help
A rather tired
