How this Discount Calculator works
A discount reduces the original price by a percentage. This tool calculates two key outputs: (1) the discount amount (how much you save) and (2) the final sale price (what you pay). It’s useful for shopping, invoices, seasonal sales, and quickly comparing two offers.
- Original price: the marked price before any offer.
- Discount %: percentage removed from the original price.
- Optional: if you later add “extra discount” or “tax after discount”, this page can support it in UI too.
Formula
Discount Amount = Price × (Discount% ÷ 100) Sale Price = Price − Discount Amount Equivalent for stacked discounts: Final Price = Price × (1 − d1) × (1 − d2) × ...
Common use cases
- Shopping: calculate final price for clothes, phones, groceries, festival offers.
- Business: compute discount on invoices and quotations instantly.
- Compare offers: percent off vs cashback vs flat discount.
- Stacked deals: “20% off + extra 10% coupon” calculation.
FAQs
Multiple discounts?
Apply sequentially. Example: ₹1000 with 20% then 10% → 1000 × 0.8 × 0.9 = ₹720 (effective 28% discount).
Tax after discount?
Often yes—tax is calculated on the discounted subtotal. However, rules and billing systems vary by country and merchant.
Rounding?
For currency, rounding to 2 decimals is common. Some invoices round per item first, then total—your receipt may differ slightly.
Return price?
Refunds typically follow the paid (discounted) price, but coupon/offer conditions may change return value.
Can discount be negative?
Yes. A negative “discount” is a price increase or surcharge.
