A "25% off" sticker tells you almost nothing until you do the math, and doing it in your head under fluorescent store lighting is where most people get it wrong. This discount calculator takes the original price and the percentage off and instantly shows the final sale price plus the exact amount you save — no mental arithmetic, no rounding guesses at the register.
It works for any single markdown: clothing sales, electronics deals, coupon codes, membership discounts or clearance racks. Because it runs entirely in your browser, nothing you type is stored or sent anywhere, so you can compare as many prices as you like while you shop.
A discount percentage is just a fraction of the original price being subtracted. Converting the percent to a decimal (25% → 0.25) and multiplying gives the amount you save directly; subtracting that from the original price gives the price you actually pay. The same formula works whether the discount is 5% or 90% — only the decimal changes.
| Original price | 10% off | 25% off | 50% off | 70% off |
|---|---|---|---|---|
| $20 | $18.00 | $15.00 | $10.00 | $6.00 |
| $50 | $45.00 | $37.50 | $25.00 | $15.00 |
| $100 | $90.00 | $75.00 | $50.00 | $30.00 |
| $250 | $225.00 | $187.50 | $125.00 | $75.00 |
Rounded to the nearest cent. Excludes sales tax, which most retailers apply after the discount.
Stacked discounts multiply, they don't add. Two 20% discounts do not equal 40% off — they equal 36% off, because the second discount applies to the already-reduced price (see Example 3 above). Sales tax is usually calculated after the discount, not before, so your final total at checkout will be a little higher than the number this calculator shows. Watch for "up to X% off" wording — it often means only a few items in the sale actually reach that top discount. And compare unit price, not just percentage: a 50%-off item that was inflated before the sale can still be a worse deal than a smaller discount on a fairly priced item.
A discount reduces the price you pay; a markup is what a retailer adds on top of their cost to set the original price in the first place. If a store marks an item up 100% and then discounts it 50%, you are paying exactly the original cost price — a "50% off" tag that isn't actually a bargain. This is why comparing prices across retailers, not just discount percentages, is the safest way to judge whether a sale is genuine.
Multiply the original price by the discount percentage (as a decimal) to find the amount saved, then subtract that from the original price to get the final price. For example, $80 at 25% off saves $20, for a final price of $60.
No. Stacked discounts multiply against the already-reduced price, not the original. Two 20% discounts in a row equal an effective 36% off, not 40%, because the second discount is calculated on the new, lower price.
No. This calculator shows the price after the discount only. Most retailers calculate sales tax on that discounted amount at checkout, so your final total will be slightly higher.
It means the maximum discount in that sale is 50%, but many items may be discounted far less. Always check the specific item's price tag or the checkout total rather than assuming the headline percentage applies everywhere.
Compare the final price to what the item typically sells for elsewhere, not just to its 'original' price. Retailers sometimes inflate the listed price before a sale so the percentage off looks bigger than the real saving.
This tool is built for percentage discounts. For a flat dollar-amount coupon, simply subtract the coupon value directly from the price — no percentage conversion needed.
