Tool details and privacy
Enter a price and a discount to see the price after the discount and how much you save. It also finds the discount rate between two prices, and the price before a discount when you know the sale price and the rate.
Price after discount = price × (1 − rate ÷ 100). Discount rate = (price before − price after) ÷ price before × 100.
Options
- The discount can be a percentage or a fixed amount.
- Three calculations: price after discount, discount rate between two prices, and price before discount.
Limits
- The discount rate is from 0 to 100, and finding the price before discount needs a rate under 100.
- Amounts take up to two decimal places.
- One discount at a time. It does not stack two discounts.

Questions
How do I calculate the price after a discount?
Multiply the price by the discount rate and divide by 100 to get the discount, then subtract it from the price. 25% off 200 is 50, so the price is 150.
How do I find the discount percentage between two prices?
Subtract the new price from the old price, divide by the old price, and multiply by 100. From 200 to 150 the discount is 25%.
How do I find the original price before a discount?
Divide the discounted price by (1 − rate). A price of 150 after 25% off was 150 ÷ 0.75 = 200.
Is 20% off and then 10% off the same as 30% off?
No. The second discount applies to the already reduced price, so the total is 28%. Work out the first discount, then enter its result as the new price.
