Instantly calculate your final price after applying discount percentages, coupon codes, and sales tax. Compare prices before and after discounts to save money.
Our discount and tax calculator helps you determine the real cost after all deductions and additions. Here's exactly how to use it:
When retailers offer multiple layers of savings — such as a store-wide sale plus a coupon code — the method of stacking matters significantly. Most retailers apply percentage discounts sequentially, not additively. For example, a 25% sale followed by an additional 15% off does NOT equal 40% off. Instead, you pay 75% of the original price (after the first discount), then 85% of that remaining amount (after the second). So $100 becomes $75 after the first discount, then $63.75 after the second — a total savings of $36.25 (36.25%), not $40. Our calculator handles sequential discount application automatically. When combining a percentage discount with a dollar-off coupon, the order usually matters too: applying a percentage discount first then a flat coupon saves more money than the reverse.
Yes! You can enter a single discount percentage along with an optional fixed-amount coupon. The calculator applies the percentage discount first, then subtracts the coupon amount, then adds the applicable sales tax.
In most jurisdictions, sales tax is applied to the discounted price (after coupons and sales), not the original price. This is because your taxable transaction amount is what you actually pay for the item. Our calculator follows this standard approach.
You can manually change the tax rate input to see how the final price varies. This is helpful when comparing the same purchase from retailers in different states or countries with varying tax rates.
A discount reduces the original price (e.g., 20% off $100 = $80), while a markup increases the base cost (e.g., 20% markup on $80 = $96). Note that getting 20% off then 20% back to the original price requires adding 25%, not 20%, because the base amount has changed.
