A discount is a reduction applied to the original price of a product or service, expressed as a percentage or a fixed amount. Understanding how discounts affect the final price — especially when combined with sales tax — is important for both consumers and business owners. Shoppers can verify whether a deal is genuinely good, while retailers can set promotional pricing that still covers costs and maintains healthy margins.

Our free discount calculator takes the original price, discount percentage, and an optional tax rate to compute your total savings, the discounted price, the tax on the discounted amount, and the final price you pay. All calculations happen instantly in your browser with no data sent to any server. Use it during sales events, when comparing offers, or when setting promotional prices for your own business.
