Formula: savings = price × discount ÷ 100; sale price = price − savings
- You entered an original price of $80.00.
- Discount: $80.00 × 25% ÷ 100 = $20.00 off, leaving $60.00.
Result: Sale price = $60.00
How a discount is calculated
savings = price × discount ÷ 100
sale price = price − savings
A percent-off discount is a share of the original price. Multiply the price by the discount as a decimal to get the amount saved, then subtract it from the price. At 25% off, an $80 item saves $20 and costs $60.
To find the discount from two prices, divide the difference by the original price: (original − sale) ÷ original × 100. Going from $80 to $60 is a $20 drop, and $20 ÷ $80 = 25%.

Two discounts in a row
When a store takes one discount and then a second, the second applies to the already reduced price. That means the two percentages do not add up. Two 20% discounts give 36% off, not 40%: $100 becomes $80, and 20% off $80 is $64.
The Price after two discounts mode works out each step and shows the total discount. A 20% discount followed by a 10% discount on $80 leaves $57.60, which is 28% off the original price instead of 30%.
Does the order of the discounts matter?
For percent discounts the order makes no difference to the final price, because each step just multiplies the price by a factor: 0.80 × 0.90 gives the same result as 0.90 × 0.80. It does matter when one of the discounts is a fixed amount off, such as $10 off, because a fixed amount is worth the same at any price while a percentage is worth more on a higher price.
This calculator handles percentages only. For a coupon of a fixed amount, subtract it from the price at the step where the store applies it.
Finding the percent off from two prices
Use this when a tag shows only the old and the new price. A jacket marked down from $120 to $90 is $30 off, which is 25%. A drop from $50 to $35 is 30%.
If the second price is higher than the first, the result is negative and the headline switches to a price increase, so you can use the same mode to check how much a price has gone up.
Discounts, tax and what you actually pay
Sales tax is normally charged on the price after the store’s discount, so the saving also lowers the tax. Take the sale price from this calculator and put it into the Sales Tax Calculator to get the final total at the register.
A discount is also not the same as the margin the seller keeps. A 20% discount on an item sold at a 40% margin cuts the seller’s profit by far more than 20%, which is why shops are careful with deep sales.

Worked example
A pair of shoes costs $80 and is 25% off. The saving is $80 × 25 ÷ 100 = $20. The sale price is $80 − $20 = $60. If the store then gives a further 10% off, the second discount takes $6 off $60 and the price is $54, a total of 32.5% off the original.
| Percent off | You save | Sale price |
|---|---|---|
| 10% | $10.00 | $90.00 |
| 20% | $20.00 | $80.00 |
| 25% | $25.00 | $75.00 |
| 30% | $30.00 | $70.00 |
| 50% | $50.00 | $50.00 |
Frequently asked questions
How do I calculate a percent off?
Multiply the price by the discount as a decimal to get the saving, then subtract it. For 25% off $80, multiply by 0.25 to get $20 and subtract to get $60.
Do two discounts add up?
No. The second applies to the reduced price, so two 20% discounts give 36% off in total, not 40%.
How do I find the discount percentage from two prices?
Subtract the sale price from the original price, divide by the original price and multiply by 100.
Is tax calculated before or after the discount?
Usually after. The tax is charged on the price you pay once the store discount is taken off.
