Discount Calculator
Find the sale price and savings after a percentage discount.
How to use this calculator
- Enter the original price.
- Enter the discount percentage.
- The result shows the final price and the amount saved.
The formula
Final price = Price × (1 − Discount% ÷ 100)- Price
- Original (pre-discount) price
- Discount%
- The advertised percentage off
How it works
A 25% discount means you pay 75% of the original: 89.99 × 0.75 = 67.49.
Stacked discounts multiply rather than add: 20% off then 10% off is ×0.8 ×0.9 = ×0.72, a 28% total discount — not 30%.
Worked example
A $89.99 jacket is 25% off.
- 1Savings = 89.99 × 0.25 = 22.50
- 2Final = 89.99 − 22.50
You pay $67.49 and save $22.50.

Frequently asked questions
Is 20% off then 10% off the same as 30% off?
No. Sequential discounts multiply: 0.8 × 0.9 = 0.72, so you pay 72% — a 28% discount.
How do I find the original price from the sale price?
Divide the sale price by (1 − discount/100). A $60 item after 25% off originally cost 60 ÷ 0.75 = $80.
