I want to know the math used to calculate mark up%. I am talking about the mark up % used by retailers to price goods for sale. The reason I want to know is so I can put the formula into a excel spreadsheet.

I want to be able to enter any two of the following. The cost amount, MU%, or selling price and be able to calculate the missing one. So I think I need 3 formulas.

I don't think I explained this very well. Sorry for the dumb question but it would be a great help if I could get it answered.
