Markdown Calculator

The markdown calculator measures a retail price reduction from an original selling price to an actual selling price. Enter the original price and the current sale price, and the result includes the markdown amount, markdown percent, actual selling price, and sale price as a percent of the original. It also handles the opposite case: if the actual price is higher than the original price, the markdown is negative and the change is better read as a markup.

This page is different from a percent-off calculator. A percent-off calculator starts with an original price and an advertised rate, then finds the sale price. This markdown calculator starts with two prices that already exist and asks how large the reduction is. It is especially useful for retailers auditing clearance decisions, ecommerce teams checking price changes, and shoppers translating a sale tag into a comparable percentage.

How to use this calculator

Enter the Original selling price, sometimes called the regular, ticket, list, or starting price. Enter the Actual selling price, which is the price after the markdown. The calculator requires the original price to be greater than zero and the actual price to be zero or higher. The primary result is Price reduction, which can be positive, zero, or negative.

The supporting lines provide context. Markdown percent expresses the price reduction as a share of the original price. Actual selling price repeats the sale price for clarity. Sale price as percent of original shows how much of the original price remains. If you already know the percent-off rate and want the sale price, use the percentage discount calculator. If a coupon is stacked on top of a markdown, use the double discount calculator.

Markdown in retail pricing

A markdown is a seller’s intentional price reduction. Retailers mark down inventory to clear seasonal goods, free shelf space, respond to weak demand, meet competitor pricing, or turn aging inventory into cash. A markdown can increase unit sales, but it lowers revenue per unit and may reduce gross margin. The best markdown decision considers inventory risk, demand, cost, and the price customers will actually pay.

Markdown percentage uses the original selling price as the denominator. That keeps comparisons consistent across products. A 20 dollar reduction on a 100 dollar item is a 20 percent markdown. The same 20 dollar reduction on a 400 dollar item is only a 5 percent markdown. The dollar cut is the same, but the pricing signal is very different.

Formula

The markdown amount is:

$\text{markdown amount} = \text{original selling price} - \text{actual selling price}$

The markdown percentage is:

$\text{markdown percent} = \frac{\text{markdown amount}}{\text{original selling price}} \times 100\%$

The sale price share is:

$\text{sale price share} = \frac{\text{actual selling price}}{\text{original selling price}} \times 100\%$

If the actual selling price is greater than the original selling price, the markdown amount and markdown percent are negative. The calculation method does not block that case because it is useful for detecting a markup or price increase.

Checking a markdown scenario

The default inputs are 100 for original selling price and 80 for actual selling price. The calculator subtracts 80 from 100, so the markdown amount is 20. It divides 20 by 100 and multiplies by 100 percent, so the markdown percent is 20 percent. It also divides the sale price by the original price: 80 ÷ 100 · 100 percent = 80 percent. The result panel shows Price reduction: 20, Markdown percent: 20 percent, Actual selling price: 80, and Sale price as percent of original: 80 percent.

If the actual selling price were 120 instead, the markdown would be 100 - 120 = -20. The markdown percent would be -20 percent, and the sale price share would be 120 percent. The calculator’s note would identify the change as a markup rather than a markdown. That behavior matches the calculation method and helps catch accidental price increases in a spreadsheet or catalog.

Shopper view

For shoppers, markdown math helps separate a meaningful price cut from a decorative sale tag. A product reduced from 100 to 80 is a 20 percent markdown. A product reduced from 120 to 100 is a 16.67 percent markdown even though both prices end at 100. Compare the actual selling price with competing stores, not just with the store’s reference price. Pricing guidance from the Federal Trade Commission exists because former-price claims can influence how consumers perceive bargains.

Markdown is also not the same as total checkout savings. Sales tax, shipping, disposal fees, installation, and return costs can change the real out-of-pocket amount. Use the sales tax calculator after you know the sale price. If the reduced item still competes with other priorities, place it in the budget calculator.

Retailer view

For retailers, markdowns are a pricing tool and an inventory tool. A markdown may be worthwhile when holding inventory is costly, demand has slowed, or cash is needed for new stock. But the markdown should be evaluated against gross margin. A 20 percent markdown on an item with a 50 percent gross margin may still leave profit; the same markdown on an item with a 15 percent gross margin may create a loss.

This calculator tells you the size of the customer-facing price cut. To evaluate profit, use the margin with discount calculator or gross margin calculator. Those tools bring cost into the analysis. A markdown plan should also consider sell-through rate: a lower margin can be acceptable if it moves enough units or avoids write-offs.

Tips and pitfalls

• Divide by the original selling price, not the actual selling price.
• Keep markdown separate from profit margin; margin needs cost.
• Check whether a coupon applies after the markdown, creating a stacked discount.
• Do not assume a large markdown is automatically the best deal if the reference price was unusually high.
• For negative markdowns, interpret the result as a markup or price increase.
• Retailers should document why markdowns are taken and review sell-through afterward.
