   SEARCH HOME Math Central Quandaries & Queries  Question from Sheldon: I know the most common form for retail businesses of calculating a price based on markup is: Cost/(1 - Markup), but how is this supposed to work for a business that desires a markup of over 100%. For example, If you have an item with a cost of $200 and you desire a markup of 300% of the selling price, then your equation should be:$200/(1-3), but this gives you a selling price of negative $100. Could you please explain to me how to calculate the final price of an item using the formula for markup on final selling price when the markup is over 100%. Thanks in advance for your help! Hi Sheldon, The markup as a dollar amount is part of the selling price so it can't be more than 100% of the selling price. In your example do you want the markup to be 300% of the cost? If so then you had a cost of$200 so the markup would be 300% of $200 or 3 ×$200 = $600. The selling price would then be$200 + $600 =$800 and the markup is 75% of the selling price.
