Discount Calculator

Enter a price and a discount percentage to see the final price and the amount you save. Also works backwards from a sale price.

Put in the original price and the discount and you get the price you actually pay, plus what you save. Or enter two prices to find the discount percentage.

    How Does It Work?

    1. Enter the original priceUse the price before any reduction — the one crossed out on the label.
    2. Enter the discount percentageType 25 for 25% off. Switch the mode if you would rather enter the sale price and find the percentage.
    3. See what you pay and saveThe final price is shown large, with the exact saving underneath.

    What Is It Used For?

    Shop labels tell you the percentage but rarely the money. This calculator turns "30% off" into a number you can compare against your budget, and works the other way round when a shop shows a sale price without saying how big the reduction is.

    • Checking a sale price in a shop before you get to the till.
    • Comparing two offers — 25% off versus a flat reduction.
    • Verifying that an advertised discount matches the price actually charged.
    • Setting a sale price for your own products and seeing the margin you give away.
    • Working out how deep a Black Friday or clearance cut really is.

    Frequently Asked Questions

    How do I calculate a discount?

    Multiply the price by the discount percentage divided by 100 to get the saving, then subtract it from the price. For 25% off 89.90: 89.90 × 0.25 = 22.48 saved, so you pay 67.42–67.43 depending on rounding.

    How do I find the discount percentage between two prices?

    Subtract the sale price from the original price, divide by the original price and multiply by 100. Switch the mode above to "Discount % between two prices" and it does this for you.

    How do two discounts stack, like 20% then an extra 10%?

    They multiply rather than add. 20% then 10% leaves 0.8 × 0.9 = 0.72 of the price, a 28% total discount — not 30%. Run the calculator twice, using the first result as the new original price.

    Does the calculator include tax?

    No, it works on the price you enter. If you need to add or remove VAT, use the VAT calculator and apply the discount first, since VAT is normally charged on the discounted price.

    Which currency does it use?

    None in particular — it works with plain numbers, so the result is in whatever currency you typed.
