Answer:

When the cost is $5.00 you add 0.30 × $5.00 = $1.50 to obtain a selling price of $5.00 + $1.50 = $6.50. This is what I would call a markup of 30%. 0.70 × (selling price) = $5.00. Thus selling price = $5.00/0.70 = $7.14.

Simply take the sales price minus the unit cost, and divide that number by the unit cost. Then, multiply by 100 to determine the markup percentage. For example, if your product costs $50 to make and the selling price is $75, then the markup percentage would be 50%: ( $75 – $50) / $50 = . 50 x 100 = 50%.

If you have a product that costs $15 to buy or make, you can calculate the dollar markup on selling price this way: Cost + Markup = Selling price. If it cost you $15 to manufacture or stock the item and you want to include a $5 markup, you must sell the item for $20.
