Calculate sale prices, savings, and total costs with discounts and optional sales tax.
Calculate the final sale price and total savings on any discount instantly with our free discount calculator, perfect for shopping and budgeting.
Discount Amount = Original Price × (Discount % ÷ 100). Sale Price = Original Price − Discount Amount.
Apply the first discount, then apply the second discount to the already-reduced price, not the original price, since stacked discounts compound.
Discount % = ((Original Price − Sale Price) ÷ Original Price) × 100.
This calculator has an optional sales tax field, apply it separately depending on whether your local tax is calculated before or after the discount.
Comparing the final sale price per unit (or the effective discount percentage) is usually more useful than comparing raw discount percentages alone.
