What is the Discount Calculator?

Calculates sale prices for any percentage off, handles “an extra 10% off” stacked discounts correctly, and can add sales tax or VAT. A second calculator tells you what percent off a price really is.

How it works

How to use the Discount Calculator

3 simple steps. No experience needed.

What can you use it for?

  • Check the price of a sale item.
  • Understand stacked discounts.
  • See what percent off a deal really is.

Good to know

Quick mental math

10% off: move the decimal one place and subtract. 25% off: take a quarter off. For stacked discounts, multiply the remaining shares — 30% then 20% off leaves 0.7 × 0.8 = 0.56, so you pay 56%.

FAQ

Frequently asked questions

Is 20% off then an extra 10% the same as 30% off?

No. The second discount applies to the already-reduced price, so it's 28% off in total.

How do I calculate 25% off?

Multiply the price by 0.75. £80 at 25% off is £60.
