Apply a discount to a price — get the sale price and the amount saved — or work out what percent off a sale really is.
Stacked discounts multiply, they don't add: 25% off then 10% off is 32.5% off, not 35%. General information only.
A percent-off discount multiplies the price by (1 − rate). Stacked discounts apply one after another, so they multiply rather than add — an important difference that stores rely on. The effective percent off shows the true combined saving.
Sale price = price × (1 − first%) × (1 − extra%)
No — it's 32.5% off, because the second discount applies to the already-reduced price. Stacked discounts always come out a little less than the sum.
This is pre-tax. Add tax on the sale price afterward with the sales tax calculator.
