How this works
Savings = Original Price × (Discount % ÷ 100) Sale Price = Original Price − SavingsThe savings amount is the discount percentage applied to the original price. The final sale price is what you actually pay after the discount is subtracted.
Examples
A 20% off sweater
A sweater is marked down 20% from $79.99. Savings are 79.99 × 0.20 = $16.00. You pay $63.99. A useful sanity check: 10% of $80 is $8, so 20% is $16 — matches.
Black Friday 40% off
A $499 pair of headphones has 40% off. Savings = 499 × 0.40 = $199.60. Final price is $299.40. Worth checking the price a week before the sale — "Black Friday pricing" is sometimes the same as regular price.
Clearance half-off
An item is 50% off $24. Savings = $12.00, final price = $12.00. At 50% off, the savings and final price are always equal.
Stacked coupons caution
An item is $100, 20% off, and you have an "extra 10% off" coupon. It is NOT 30% off. Apply the 20% first ($80), then 10% off of that ($72). Total effective discount is 28%, not 30%.
Common questions
The easiest trick is to find 10% first (move the decimal one place left) and scale up. For 30% off $80: 10% of 80 is $8, so 30% is $24. Sale price: $80 − $24 = $56. For 15% off, find 10% and then add half of that.
Because the second discount is applied to an already-reduced price, not the original. A 20% discount followed by a 10% discount on $100 gives you $100 → $80 → $72, which is a 28% total discount, not 30%. Each successive discount has a smaller base to work from.
Sometimes. Some retailers inflate the "original" price shortly before a sale so the discount looks larger than it is. Price-tracking browser extensions and price-history sites can show you the real historical baseline.
Sales tax is applied to the discounted price, not the original. For a $100 item with 20% off in a 7% tax jurisdiction: sale price is $80, tax is $5.60, total paid is $85.60.
Two items at regular price cost 2× the price. With BOGO 50%, you pay 1.5× the price for two items. Effective discount per item is 25% — not 50%. "BOGO free" is a 50% discount per item.
