Discount Calculator — Sale Price & Money Saved
Enter an original price and a percent off to see the sale price and the exact amount you save — $80 at 25% off is $60, saving $20. Check deals before you buy.
Examples
Original price: $80 · Discount: 25%
Sale price: $60.00 You save: $20.00
Sale price = 80 × (1 − 0.25) = 60; savings is the $20 difference.
$80, 25% off, then an extra 10% off the reduced price
After 25% off: $60.00 After 10% off $60: $54.00 (total saved $26.00)
Stacked discounts apply in sequence, not as a combined 35% — 10% comes off the already-reduced $60.
How Discount Calculator works
Discount Calculator turns an original price and a percent-off into the final sale price and the dollar amount you save. The sale price is the original times one minus the discount, and the savings is simply the gap between the two. It answers the question every shopper actually has at the shelf or checkout — is this deal as good as the sticker makes it sound, and how much am I really keeping.
How to use this tool
- Enter the original price.
- Enter the discount percentage.
- See the sale price and savings.
Tips & gotchas
- Stacked discounts multiply, they don't add: 25% then 10% off is a 32.5% total reduction, not 35%.
- Apply sales tax AFTER the discount — tax is charged on the price you actually pay, so a bigger discount also trims the tax.
- A flat amount off beats a percentage on cheap items but loses on expensive ones; compare both for the specific price.
- Watch the base: some "extra % off" coupons apply to the original price, others to the already-reduced price — the order changes the total.

Frequently asked questions
How is the sale price calculated?+
Sale price = original price × (1 − discount%). The savings is the difference between the original and sale price.
How do I stack two discounts?+
Apply them in sequence: take the first percent off, then use that result as the new starting price for the second. Two stacked percentages multiply rather than add, so 25% then 10% is a 32.5% total reduction.
Should I add sales tax before or after the discount?+
After. Tax is charged on the discounted amount you actually pay, so calculate the sale price first and then apply tax to it.
