How to Use This Discount Calculator
Enter the original price of any item and the discount percentage. Our calculator instantly shows you the discount amount in dollars, the final sale price you pay, and your total savings. You can also work backwards — enter the sale price and original price to find what percentage discount was applied.
Discount Calculation Formula
Sale Price = Original Price × (1 – Discount% ÷ 100)
Savings Amount = Original Price × (Discount% ÷ 100)

Stacked Discounts – How They Really Work
Many shoppers assume that two discounts add together — a 20% off sale plus an extra 10% off coupon equals 30% off. This is incorrect. Stacked discounts apply sequentially, not additively.
| Original Price | First Discount | Price After First | Second Discount | Final Price | Total % Saved |
|---|---|---|---|---|---|
| $100 | 20% off | $80 | 10% off | $72 | 28% (not 30%) |
| $200 | 30% off | $140 | 15% off | $119 | 40.5% (not 45%) |
| $500 | 25% off | $375 | 20% off | $300 | 40% (not 45%) |

Frequently Asked Questions
To find what percentage discount you received: subtract the sale price from the original price, divide that number by the original price, then multiply by 100. Example: original price $80, sale price $60. Savings = $20. Discount % = (20 ÷ 80) × 100 = 25% off. Our calculator does this instantly in either direction — you can find the final price from a percentage, or find the percentage from two prices.
A discount reduces the price you pay at the point of purchase — the savings are immediate. A rebate is a partial refund you receive after the purchase, usually by submitting a form or receipt. Rebates require effort and waiting (often 4–8 weeks) and have redemption rates as low as 20–40% because many people forget or don’t complete the process. A 20% discount is almost always more valuable than a 20% rebate.
Divide the sale price by (1 minus the discount as a decimal). Example: if an item is on sale for $75 after a 25% discount: $75 ÷ (1 – 0.25) = $75 ÷ 0.75 = $100 original price. This reverse calculation is useful when you see a sale price and want to verify the original price or confirm that the stated discount percentage is accurate.
For some items yes, but not always. Studies show that Amazon Prime Day (July) often has comparable or better deals on many electronics categories. TVs are genuinely cheapest around Super Bowl Sunday (January–February) and Black Friday. Laptops are best priced during Back to School season (August). New product launches (September for Apple, year-round for others) push older models to steep discounts. The best approach is to track prices using tools like CamelCamelCamel (Amazon) or Google Shopping alerts.
Sales tax is calculated on the final discounted price, not the original price — so discounts also reduce the amount of tax you pay. For example, on a $100 item with 8% sales tax and 20% discount: without discount you pay $100 + $8 tax = $108. With 20% discount you pay $80 + $6.40 tax = $86.40. Total savings including tax reduction = $21.60, slightly more than the face value of the 20% discount.
