Sale Price$150.00
You Save$50.00
This percent off calculator turns a "25% off" tag into real numbers: it shows the exact dollars you save and the final sale price you will pay at the register. Enter the original price and slide the discount percentage from 0 to 100, and the tool multiplies the two to find the markdown, then subtracts it from the original price. It is built for shoppers comparing storewide sales, clearance racks, and coupon stacking on a single item.
Formula
Amount saved = Price × (Percent off ÷ 100); Sale price = Price − Amount saved
- Price
- Original (pre-discount) price in dollars
- Percent off
- Advertised discount as a percentage
- Amount saved
- Dollars removed by the discount
- Sale price
- What you actually pay after the markdown
How it works
- Enter the original Price in dollars in the input field.
- Drag the Percent Off slider (0%-100% in 1% steps) to the advertised discount.
- The Sale Price hero card shows what you pay after the markdown, and the You Save card shows the dollar amount removed; both round to the nearest cent.
Worked examples
A jacket marked $89.99 is 40% off.
- Amount saved = 89.99 × (40 ÷ 100) = 89.99 × 0.40 = 35.996, rounded to $36.00.
- Sale price = 89.99 − 36.00 = $53.99.
You save $36.00 and pay $53.99 before any sales tax.
An item priced $200 is 25% off.
- Amount saved = 200 × 0.25 = $50.
- Sale price = 200 − 50 = $150.
You save $50 and pay $150.
Frequently asked questions
- Does this include sales tax?
- No. The result is the pre-tax sale price. Sales tax is applied to the discounted price afterward, so your final checkout total will be higher by your local tax rate times the $53.99-style sale price.
- How do I stack two percent-off discounts?
- Stacked percentages multiply rather than add. A 20% coupon on top of a 30%-off price leaves you paying 0.80 × 0.70 = 56% of the original, a 44% total discount, not 50%. Run the first percent off, then feed the result back in as the new price.
- What is the difference between percent off and percent of?
- Percent off is the discount removed, while percent of is what remains. An item 30% off costs 70% of its original price, so "30% off" and "pay 70% of price" describe the same sale price.
