Discount calculator

See the sale price after a discount, an extra discount on top, and tax.

Optional, applied after the first.
Optional, such as 5 for UAE VAT.

Worked example

A price of 2,500 with 20% off is 2,000. An extra 10% off that is 1,800. Together that is 700 off, or 28%, not 30%.

If 5% VAT is then added, the final price is 1,800 × 1.05 = 1,890.

Common questions

How do I work out a discount?

Multiply the price by the discount percentage and divide by 100, then take that off the price. 20% off 2,500 is 500, so you pay 2,000.

Are two discounts the same as adding them?

No. 20% off and then 10% off is 28% off in total, because the second discount is taken from the already reduced price.

Is VAT added before or after the discount?

Usually after. The calculator applies tax to the discounted price.
