Discount and Markup Calculator

Work out a sale price and the amount saved after a discount, or convert between cost, price, markup and margin. Results are exact until the final step, and money is shown to the cent.

How it works

Sale price after a discount. Sale price = price × (1 − discount ÷ 100). The amount saved = price − sale price. For example, 80 with 25% off is 80 × 0.75 = 60.00, and you save 20.00.

Markup is the profit as a percentage of cost: markup % = (price − cost) ÷ cost × 100. Margin is the profit as a percentage of the selling price: margin % = (price − cost) ÷ price × 100. They use the same profit but a different base, so they are never equal unless the profit is zero. Cost 40 sold at 50 gives a markup of 25% and a margin of 20%.

Price from cost and markup is price = cost × (1 + markup ÷ 100). Price from cost and margin is price = cost ÷ (1 − margin ÷ 100), so a margin of 100% or more cannot give a price. Cost from price and margin is cost = price × (1 − margin ÷ 100).

A negative markup or margin means the item is sold below cost. Cost or price of 0 is refused only where a division needs it, for example markup needs a cost above 0.

Rounding. Every step is worked out exactly, with no rounding in between. Only the final amounts and percentages are rounded, to 2 decimal places, round half up: 10.004 shows as 10.00 and 10.005 shows as 10.01. A negative value rounds the same way, away from zero. These figures are before tax, shipping and any other deductions.
