Discount Calculator

Discount Calculator Free Online Tool

Our discount calculator free online tool shows you the sale price and the amount you save in one step. Enter the original price and the discount percentage, and the result appears instantly. There is nothing to install and no sign-up, and everything runs directly in your browser.

How to Calculate Discount Percentage

If you want to know how to calculate discount percentage, the formula is simple: subtract the sale price from the original price, divide by the original price, then multiply by 100. For example, a jacket that was $120 and now costs $90 has a discount of ($120 − $90) ÷ $120 × 100 = 25%. The calculator does this math for you, so you can check any deal in seconds.

Use this sale price calculator online when you see "30% off" on a tag and want the final price before you reach the checkout. Type the original price and the percentage, and the tool shows both the amount saved and the price you will pay. It is handy for shopping trips, online stores, and for shop owners who set promotion prices. If you run a store page, add a scannable link to it with our QR Code Generator.

Original Price Calculator After Discount

Sometimes you only know the final price and the discount. This original price calculator after discount works backward to find what the item cost before the sale. The formula is: original price = sale price ÷ (1 − discount ÷ 100). If you paid $60 after a 25% discount, the original price was $60 ÷ 0.75 = $80.

Percentage Off Discount Calculator

This percentage off discount calculator handles the most common deals, such as 10%, 15%, 25%, 40% and 50% off. You can type any percentage, including decimals like 12.5%. The result is rounded to two decimal places, which makes it suitable for receipts, invoices and price lists.

How to Figure Out Sale Price

Here is how to figure out sale price by hand when you do not have a calculator. Multiply the original price by the discount percentage and divide by 100 to get the amount saved, then subtract it from the original price. A quick shortcut: for 20% off, multiply the price by 0.80, and for 35% off, multiply by 0.65. Use the tool below to confirm your mental math.

Tips for smarter shopping

Compare the final price, not just the percentage, because 40% off a high price can cost more than 20% off a low one.
Remember that stacked discounts are not added together: 20% off followed by 10% off equals 28% off, not 30%.
Check whether sales tax is applied before or after the discount in your area.
Use the original price calculator to confirm that a "sale" price is a real reduction.
