Percent Off Calculator

Percent off calculator: how to calculate discount

Enter any two known values to find the remaining prices and savings. For a percentage discount, savings = original price × discount rate ÷ 100, and sale price = original price − savings. For example, 15% off $59.99 saves $8.9985 and gives a sale price of $50.9915, displayed as $9.00 saved and $50.99 to pay.

Discount calculator for percentage or dollar savings

Choose a percentage discount or a fixed dollar discount. In percentage mode, you can enter any two of original price, discount rate, sale price, and amount saved. In dollar mode, enter any two of original price, discount amount, and sale price. Leave the other fields blank so the calculator knows what to solve.

Percentage discount calculator: reverse a sale price

To recover the original price from a sale price and discount percentage, divide the sale price by (1 − discount rate ÷ 100). For example, a $60 sale price after 25% off implies an $80 original price. Savings divided by original price, multiplied by 100, gives the percent off.

Frequently asked questions

How to calculate percent off?

Multiply the original price by the discount percentage divided by 100 to get savings, then subtract savings from the original price. This is how to calculate discount for a single percentage reduction.

How to calculate discount percentage?

Subtract the sale price from the original price, divide that difference by the original price, and multiply by 100. The original price must be greater than zero.

How do I calculate 20 percent off?

Multiply the original price by 0.80 for the sale price, or by 0.20 for the savings. A $50 item becomes $40, saving $10.

Can the discount calculator find the original price?

Yes. Enter the sale price and a percentage below 100%, or enter the sale price and the dollar amount saved. Clear the original price before calculating.

Why do some pairs of values have no unique answer?

A zero discount rate together with zero savings does not identify the original price. Likewise, a 100% discount and a zero sale price could apply to any original price. Enter a known original price or a different pair instead.

Can I calculate a free item or no discount?

Yes. Enter an original price with a 100% or 0% discount. If the original price is zero, the percentage discount is undefined, but the dollar amounts can still be shown.
