Discount Calculator works out a sale price in your browser. Enter the original price and the percentage off to instantly see the final price, how much you save and the discount amount, and add an optional sales tax rate that is applied after the discount, just like a real receipt. You can set any currency symbol, the results update as you type, and nothing is saved or uploaded.

Frequently asked questions

Is anything saved or uploaded?

No. The calculation runs instantly in your browser with simple maths, and nothing you type is sent anywhere or stored.

How is the final price worked out?

The discount is taken off the original price first, then any sales tax is added to that reduced amount, which is how most shops and receipts calculate it.

Can I change the currency?

Yes. Type any symbol you like into the currency box, such as a pound, euro or rupee sign, and every result updates to use it.

Is the sales tax optional?

Yes. Leave the tax field blank or at zero and it simply shows the discounted price. Add a rate and it shows the tax amount and the final total including tax.

Can it handle decimals?

Yes. You can enter prices and percentages with decimals, and the results are rounded to two decimal places for money.
