Calculate a sale price after discount
Enter a price and a discount to see the price you pay and how much you save. Add a second discount to see what 'an extra 10% off' is really worth.

How it works
- Enter the original price.
- Enter the discount in percent, and a second discount if there is one.
- Read the final price, the amount saved and the total discount.
How discounts are calculated
Final price = price × (1 − discount ÷ 100). 25% off 80 is 80 × 0.75 = 60, a saving of 20.
Stacked discounts are not added together
A second discount applies to the already reduced price: 20% off and then an extra 10% off 200 gives 200 × 0.8 × 0.9 = 144. That is 28% off in total, not 30%.
Discount or bigger quantity?
'Buy 2, get 1 free' is a 33% discount on each item, but only if you need three. Compare the final price per item, not the headline percentage.

| 3,999.00 | 25% | 5% | 2,849.29 | 1,149.71 |
Frequently asked questions
Does the order of two discounts matter?
No. 20% then 10% and 10% then 20% give the same final price.
How do I find the original price?
Divide the sale price by what is left: 60 after 25% off was 60 ÷ 0.75 = 80.
Does it include sales tax or VAT?
No. Apply tax to the final price separately; the percentage calculator can help.
