Find the sale price for any item, with optional support for stacked promotions and sales tax. Useful for comparing promotional offers, building budget estimates, or pricing your own products.
How it works
The calculator uses plain JavaScript arithmetic. The sale price equals the original price times one minus the discount expressed as a decimal. Stacked and double-discount modes apply each percentage in turn so every subsequent discount lands on the already-reduced amount, which is why the effective percent off is always lower than the sum of the individual rates.

Frequently asked questions
- Is my pricing information stored or sent anywhere?
- All calculations run locally in your browser. Our servers are not involved at any point.
- Can I model a coupon on top of a sale?
- Yes. Stacked mode lets you add a chain of percentages so a coupon code applied after a sale price uses the already-reduced amount as its base.
- Is the calculator suitable for B2B quotations?
- Yes. Enter the gross price and supply your standard discount rate to see the net price and the saving. Add a tax rate for the tax-inclusive total.
- How precise are the rounded results?
- The displayed numbers are rounded to two decimal places for currency presentation, while the underlying calculation uses full floating-point precision.
- Does the tool handle a percentage markup as well?
- The tool focuses on discounts. To compute a markup, swap the sign and use the percent-off field as a negative number, or pair this tool with the percentage calculator.
