Discount Calculator

Calculate the sale price after a percentage discount, how much you save, and the final total with tax.

Shoppers checking real savings on sales, coupons, and Black Friday deals.

How to use it

  1. Enter the original price

    Type the item’s pre-discount price.

  2. Enter the discount

    Add the discount percentage, and optionally a tax rate to apply afterward.

  3. See your savings

    View the final price, how much you save, and the discounted price before tax.

Why use this tool?

Shops advertise the percentage off because it sounds dramatic, but the number you actually need is the final price and how much you really save — and that gets fiddly when tax is added on top or when you are comparing deals on the spot. Working out "25% off, then add tax" in your head while standing in a store or scrolling a sale is exactly where people overpay or misjudge whether a deal is worth it. This calculator gives you all the figures at once: enter the original price and the discount, optionally add a tax rate, and see the final price, the amount saved, and the discounted price before tax. The order matches how checkouts work — the discount comes off first, then tax applies to the reduced amount — so the result mirrors what you will actually pay. It runs in your browser, the maths is currency-agnostic, and there is no sign-up.

Common use cases

Find the true price of a "30% off" deal — and how much you actually save — before buying.

Black Friday & big sales

Compare deals quickly while shopping so you can tell a real bargain from a small one.

Retail & invoicing

Apply a discount and tax line to quote a clear customer price.

Budget shopping

Check whether a sale item lands within your budget once tax is included.

Reselling & markdowns

Work out a markdown price and confirm the final figure after tax.

Frequently asked questions

How is the discount applied?

The discount is taken off the original price first, then any tax is applied to the discounted amount — the same order as a typical checkout.

How do I calculate the final price myself?

Final = original × (1 − discount%) × (1 + tax%). The tool does this for you and also shows the amount saved.

Can I leave tax blank?

Yes. Set tax to 0 to see just the discounted price with no tax added.

Can it handle stacked discounts?

Apply them in sequence: take the result of the first discount as the original price, then apply the second.

Does it tell me the amount saved?

Yes — it shows the savings in money, not just the percentage, so you can see the real benefit.

Does it work in any currency?

Yes. The maths is currency-agnostic; just read the figures in your own currency.

Is my data stored?

No. Everything is calculated in your browser.

Is it free?

Yes — work out as many discounts as you need for free, with no account.
