What will I actually pay?

Enter a price and discount to see the final price and your savings. Add a second "extra % off" to see why 25% + 10% isn't 35% off.

Add sales tax or VAT to get the total at the till.

  1. 1

    Enter the price

    Before discount.

  2. 2

    Add discounts

    And tax if it applies.

  3. 3

    See the total

    Plus your savings.

Frequently asked questions

Why isn't 20% + 20% equal to 40% off?

The second discount applies to the already-reduced price, so it works out to 36% off.

Is tax added before or after the discount?

After — tax is calculated on what you actually pay.

Is my data uploaded anywhere?
