How to calculate 20% off?

Multiply the original price by 0.80, or enter the price and 20% in this calculator. For a $100 item, 20% off gives a sale price of $80. You can also enter a fixed dollar discount instead of a percentage when a coupon shows an absolute amount off.

Stacked 20% + 10% off?

Stacked percent discounts apply sequentially, not as a single sum. Twenty percent off then ten percent off the reduced price equals 28% total off, not 30%. The calculator shows the effective combined discount and final sale price so you can compare stacked offers accurately.

Fixed amount vs percent?

Enter either a discount percentage or a fixed dollar amount off the original price. Percent discounts scale with price; fixed amounts stay constant regardless of the starting price. Store exclusions and tax-on-discounted-price rules vary by jurisdiction and retailer policy worldwide.
