Is this discount calculator free?

Yes, completely free with no signup required. All calculations happen in your browser.

Does my data leave my device?

No. The discount calculator runs entirely in your browser. Your price and discount values are never sent to any server.

Does it work on mobile?

Yes. The tool is mobile-first and works on iPhone Safari and Android Chrome.

How is the sale price calculated?

Sale price = Original price × (1 − Discount% ÷ 100). For example, $100 at 20% off = $100 × 0.80 = $80.

Can I use it for stacked discounts?

For a single discount percentage, yes. For stacked discounts (e.g., 20% then 10%), apply the calculator twice — first for the larger discount, then the result as the new price.
