What is Margin/Markup?
Margin and markup are different: margin is profit as % of selling price; markup is profit as % of cost. Mixing them up causes pricing errors.
How it works
Margin% = (price - cost) / price x 100. Markup% = (price - cost) / cost x 100. We solve for unknowns given any two known values.
