Discount Calculator
Calculate the sale price after a discount, or find out what percentage off you are getting.
This free discount calculator works two ways: enter the original price and a discount percentage to find the sale price and how much you save, or enter the original and sale prices to find the discount percentage. It runs instantly in your browser.
How to Calculate a Discount
Multiply the original price by the discount percentage and divide by 100 to get the savings. Subtract the savings from the original price to get the sale price. For example, 25% off $120 saves $30, so the sale price is $90. This calculator does it for you instantly.
Frequently Asked Questions
How do I calculate 30 percent off a price?
Multiply the price by 0.30 to get the savings, then subtract. On $249, 30 percent off saves $74.70, making the sale price $174.30.
Can I find the percentage off from two prices?
Yes. Switch to the second mode, enter the original and sale prices, and the calculator shows the exact discount percentage and savings.
Do multiple discounts add up equally?
No. Each discount applies to the already-reduced price. 20 percent off plus 10 percent off equals 28 percent total, not 30 percent.

Discounts are applied before tax. Sales tax is calculated on the discounted price, not the original.
