Discount Calculator
Turn a list price and percent off into a sale price, with a second discount and VAT, or work back to the original price.
How to use
- Pick a mode: ‘List price → final price’ gives the discounted price, ‘Sale price → original price’ works backwards. The currency is won or dollars.
- Enter the list price (in reverse mode, the sale price with VAT included) and the discount rate in %. Type 30 for 30% off.
- In ‘List price → final price’ you can add an extra discount, and in both modes a VAT rate. Empty fields count as 0%.
- The original price, discount, VAT, effective discount and final price appear instantly, and the copy button copies a one-line summary.
FAQ
What is the price of a 50,000 item at 30% off?
Enter 50000 as the list price and 30 as the discount rate: the final price is 35,000 and the discount is 15,000. The formula is list price × (1 − discount rate).
How do stacked discounts work?
The extra discount applies to the amount already discounted. 30% off 50,000 and then 10% more goes from 35,000 to 31,500, an effective 37% off (18,500), not 40%.
When is VAT added?
VAT is added on top of the fully discounted amount. With a VAT rate of 10 on the 31,500 above, VAT is 3,150 and the final price is 34,650.
How do I find the original price from a sale price?
Choose ‘Sale price → original price’ and enter a sale price of 35,000 and a discount of 30%: the original price is 50,000. If the sale price already includes VAT, enter the VAT rate too, for example 10, and the tool removes the VAT first, giving 45,455.
How do I find the discount rate from two prices?
(list price − sale price) ÷ list price × 100. A price falling from 50,000 to 35,000 is 30% off. This calculator takes the discount rate as an input, so use the ‘Change rate’ mode of the Percentage Calculator on this site: 50000 and 35000 give -30%.
Can I enter decimals or 100% off?
The discount rate can be any value from 0% to 100%, decimals included. 33.3% off 19,900 gives 13,273 (a 6,627 discount), rounded to the nearest unit. Reverse pricing only works below 100%.
Can I use dollars?
Yes, choose US dollar as the currency. Amounts are typed in whole dollars and results show cents: 15% off $19 gives $16.15.
