Sale price in a second

A discount of 30 percent on 80 takes off 24, so you pay 56. The calculator shows both the final price and the amount saved, for any currency. Stacked discounts are applied one after another: 20 percent off and then another 10 percent off is 28 percent in total, not 30. Enter the first result as the new price to check it.

Shops, marketplaces and Black Friday deals often show the old and the new price; use the percentage change card below to find the real discount percentage from those two numbers.

Before and after tax

If tax is added at the checkout, apply the discount first, then the tax with the increase card. The order does not change the final amount, since both are percentages of the same base.

Frequently asked questions

How do I calculate 25% off?

Multiply the price by 0.75. A price of 60 becomes 45, a saving of 15.

How do I calculate a percentage of a number?

Multiply the number by the percentage and divide by 100. 15% of 80 is 80 × 15 / 100 = 12.

How is percentage change calculated?

Subtract the old value from the new one, divide by the old value and multiply by 100.

How do I find the price before tax?

Divide the price including tax by 1 plus the tax rate, for example 120 / 1.2 = 100 for 20% tax.

Can I use a comma as decimal separator?

Yes. Both 12,5 and 12.5 work.
