Discount Calculator — Percent Off Calculator
Calculate the sale price after a percentage off, find what discount was applied, or work out the original price before discount.
How to Calculate a Discount
To find the sale price after a percentage discount: Sale Price = Original Price × (1 − Discount/100). For a ₹2,000 item with 20% off: ₹2,000 × 0.80 = ₹1,600. The saving is ₹400. To find what percentage discount was applied: Discount % = (Original − Sale) / Original × 100. For example: (₹2,000 − ₹1,600) / ₹2,000 × 100 = 20%.
Common Discount Calculations
10% off: Multiply price by 0.90. 20% off: Multiply by 0.80. 25% off: Multiply by 0.75. 50% off: Divide by 2. Buy one get one free (BOGO): Equivalent to 50% off if buying both. This calculator handles all of these instantly.
Multiply the price by 0.80. For ₹500: ₹500 × 0.80 = ₹400. You save ₹100.
Original = Sale Price ÷ (1 − Discount/100). If you paid ₹800 after 20% off: ₹800 ÷ 0.80 = ₹1,000 original. Use the "Find Original Price" tab above.
₹1000 × 0.70 = ₹700. You save ₹300.
