Discount Calculator
Work out the sale price and how much you save in seconds.
About this tool
A discount calculator works out the final price of an item after a percentage is taken off, and shows exactly how much you save. Enter the original price and the discount percentage, and the sale price and your savings appear instantly — no mental math required while you are standing in a store or comparing deals online.
The math is straightforward: the amount saved is the original price multiplied by the discount percentage divided by 100, and the final price is the original price minus that saving. A 25% discount on a $100 item, for example, saves you $25 and leaves a sale price of $75. The calculator handles any percentage from 0 to 100, so it works for small promo codes and deep clearance markdowns alike.
Use it while shopping the sales, checking that an advertised discount matches the price at the register, comparing two offers with different percentages off, or working out a markdown when you are the one setting prices. Everything is calculated in your browser — no prices are uploaded, logged or stored anywhere.
Examples
Input
$100 original price at 25% off
Output
Final price $75.00 · you save $25.00
Input
$59.99 original price at 40% off
Output
Final price $35.99 · you save $24.00
Input
$250 original price at 15% off
Output
Final price $212.50 · you save $37.50
A smaller percentage off a larger price still adds up to a meaningful saving.

Frequently asked questions
Is this discount calculator free?
Yes. It is completely free to use with no sign-up, no limits and no hidden charges.
How is a discount calculated?
The amount saved is the original price multiplied by the discount percentage, divided by 100. The final price is the original price minus that saving. So a 25% discount on $100 saves $25 and leaves a final price of $75.
How do I work out a percentage off a price?
Multiply the price by the percentage and divide by 100 to get the saving, then subtract it from the price. This calculator does both steps for you the moment you type the numbers in.
Does this include sales tax?
No. The calculator works out the discounted price before tax. Any sales tax is applied to the final price afterwards at the rate for your location.
Is my price data private?
Yes. Every calculation runs locally in your browser. The original price and discount you enter are never sent to a server, logged or stored.
