Calculate sale price, original list price, discount percentage, and savings, with optional quantity, sales tax, and currency formatting for a complete price breakdown.

Formatting only; no currency conversion.

Quantity and tax

Optional; blank uses one item.

Optional; blank uses zero tax.

List Price Formula

The calculator uses one of three formulas depending on which value you need to find.

Sale Price = List Price × (1 - Discount / 100)
List Price = Sale Price / (1 - Discount / 100)
Discount % = (1 - Sale Price / List Price) × 100
  • List Price — the original price before any markdown
  • Sale Price — the price after the discount is applied
  • Discount — the percent reduction off the list price

Discount must be between 0% and 100%. Finding an original list price requires a discount below 100%; finding a percentage requires a positive list price. These three formulas exclude tax; the optional breakdown applies the entered tax rate to the discounted quantity subtotal. Shipping, fees and stacked coupons are excluded. For multiple discounts applied in sequence, calculate each step on the new running price, not on the original list price.

Reference Tables

Quick lookup for what you actually pay and what you save at common discount levels.

List Price 10% off 25% off 40% off 50% off 70% off
$25$22.50$18.75$15.00$12.50$7.50
$50$45.00$37.50$30.00$25.00$15.00
$100$90.00$75.00$60.00$50.00$30.00
$250$225.00$187.50$150.00$125.00$75.00
$500$450.00$375.00$300.00$250.00$150.00

Stacked discounts do not add. Two markdowns of 20% and 25% taken in sequence work out like this:

Discounts Applied Combined Sounds Like Actual Total Off
20% then 10%30%28%
25% then 20%45%40%
30% then 15%45%40.5%
50% then 25%75%62.5%

Example Problems

Find the sale price. A jacket lists for $120 at 35% off. Sale price = 120 × (1 − 0.35) = $78. You save $42.

Find the original price. You paid $63 for a pair of shoes marked 30% off. List price = 63 / (1 − 0.30) = $90.

Find the discount percent. A $200 item is on sale for $149. Discount = (1 − 149/200) × 100 = 25.5% off.

Is "list price" the same as MSRP? MSRP is the manufacturer's suggested retail price. A seller's list price is its posted pre-discount price and may differ from MSRP.

Why does the calculator block 100% off when finding the original price? At 100% off, a zero sale price is compatible with any nonnegative list price, so there is no unique answer. A positive sale price is incompatible with a 100% discount.
