How the discount calculator works
"30% off" sounds good, but what do you actually pay? Enter the original price and the discount to see your savings and the final price side by side — before you reach the checkout.
The formula
sale price = price × (1 − discount ÷ 100) · savings = price − sale price
Worked example
A $85 pair of shoes is 30% off. Multiply 85 by 0.70 to get a $59.50 sale price. You save $25.50.
Where this comes in handy
- Clothes and electronics: verify the real final price behind big "SALE" signs.
- Stacked deals: apply a 20%-off coupon on top of a 30%-off clearance item.
- Bulk buys: compare per-unit savings across different discount tiers.
- Negotiating: know your walk-away price before you start talking numbers.
Discount Calculator — frequently asked questions
How do you calculate a discount?
Multiply the price by (1 − discount ÷ 100). For 25% off $80: 80 × 0.75 = $60. The savings are $20.
How do stacked discounts work?
Apply them one after another, not added together. A 30% clearance plus a 20% coupon means paying 70% then 80% of that: 0.70 × 0.80 = 56% of the original — a 44% total discount, not 50%.
What is the difference between discount and rebate?
A discount lowers the price you pay now. A rebate returns part of the money later, after purchase — so the upfront cost is higher.
Do discounts apply before or after tax?
Usually the discount comes off first and sales tax applies to the reduced price — which saves you a little extra. Store policies can vary.
How can I quickly estimate 15% off in my head?
Find 10% (move the decimal one place), halve it for 5%, and add them together. For $60: $6 + $3 = $9 off.
