Calculate savings, final prices, and chain discounts
Our Discount Calculator helps you determine the final price after applying one or more discounts sequentially. Whether you're shopping during a sale, comparing coupon offers, or figuring out a business discount structure, this tool shows exactly how much you save at each step.
Chain discounts are common in retail and wholesale — for example, "20% off plus an extra 10% off" is a chain discount where each discount applies to the progressively reduced price. Understanding this compounding effect helps you evaluate the true value of multi-tier promotions.
Chain discounts are applied sequentially, with each discount calculated on the remaining price after the previous discount. For example, 20% off followed by 10% off on a $100 item: after 20% off the price is $80, then 10% off $80 is $72 — a total saving of 28%, not 30%.
Sales tax is typically calculated on the final discounted price, not the original price. This calculator applies discounts first, then computes tax on the discounted amount — which is the standard retail practice.
A discount is a general price reduction (e.g., a store-wide sale), while a coupon is a specific offer that must be redeemed. Both reduce the price, but coupons often have restrictions like minimum purchase requirements or expiration dates.
Divide the total savings (original price minus final price) by the original price and multiply by 100. For chain discounts, this effective rate is always less than the sum of the individual percentages due to compounding.
A BOGO (buy one, get one free) on two identical items is equivalent to a 50% discount on the total purchase. A "buy one, get one 50% off" equals a 25% discount overall. This calculator can model such scenarios by entering the total as the original price and applying the equivalent discount.
