Frequently asked questions
How do I calculate a percentage discount?
Multiply the original price by the discount rate, then subtract. Example: 25% off $80 → $80 × 0.25 = $20 saved → sale price $60. The formula is sale = price × (1 − d/100).
How do stacked (double) discounts work?
Stacked discounts are not additive. A 30% discount followed by an extra 20% off is not 50% off — it is 44% off. Each discount applies to the already-reduced price: 100 → 70 → 56, so you saved 44 out of 100. Use the Stacked tab to get this correct.
Is sales tax calculated before or after the discount?
In most US states and in the EU with VAT, tax is charged on the discounted price — so discount first, tax second. This calculator follows that standard order: sale price → add tax → add tip. Some promotions (manufacturer coupons, not store coupons) use a different rule, so check your receipt if it matters.
How do I find the original price from a sale price?
Use the Reverse tab. If you paid $60 after a 25% discount, the original was $60 ÷ (1 − 0.25) = $80. Formula: original = sale ÷ (1 − d/100).
What is the effective discount on a BOGO (buy-one-get-one) deal?
A true BOGO (buy one, get one free) is a 50% discount per pair — you get 2 items for the price of 1. BOGO 50% off the second item is equivalent to 25% off the pair. Enter the pair total as the original price and use the correct percentage to see the per-item effective price.
How is the fixed-amount discount different from a percentage?
A fixed-amount discount subtracts a flat currency value regardless of the price, e.g. $15 off. The same $15 is a larger percentage on cheaper items: $15 off $50 is 30%, but $15 off $150 is only 10%. The Fixed amount tab shows both the sale price and the effective percentage saved.
Results are for guidance. Check your receipt for the exact tax and rounding rules used by the retailer.
Work out the sale price and the amount saved from any discount in four clicks. Pick a mode — Basic (price minus percentage off), Reverse (recover the original price from what you paid), Fixed amount (flat cash off, with the effective percentage shown), or Stacked (two discounts applied one after the other, the way retailers really apply them).
Choose a currency (USD, EUR, GBP, INR, AUD, CAD, JPY), optionally switch on sales tax or VAT and a tip, then type the numbers. The calculator shows the final price, amount saved, effective percentage and a visual breakdown of price vs. savings. Presets cover 10%, 15%, 20%, 25%, 30%, 50% and 70% off.
Examples: 30% off $80 gives $56 saved $24. A coupon of $15 off a $60 bill is an effective 25% discount. A 30% sale plus an extra 20% loyalty discount on $100 leaves $56, a total 44% off — not 50%, as often assumed.
