Plan the numbers
Calculate sale prices, net savings, and successive stacked discounts (e.g. 50% + 20% off) instantly. Determine true discount percentages from MRP to checkout price.
Retail promotional sales frequently employ 'Double Discount' phrasing (such as 'Flat 40% Off + Extra 20% Off'). Because consecutive discounts compound multiplicatively rather than additively, 40% + 20% yields a net 52% reduction, not 60%.
Calculate discount amount, savings, and final sale price instantly.
Successive discounts apply to the diminishing balance: $Net \, Price = MRP \times (1 - d_1) \times (1 - d_2)$. On a ₹1,000 item, '50% + 20%' yields ₹400 final price (saving ₹600 or 60%), never 70%.
Enter the pre-discount sticker price (e.g., ₹2,499).
Specify the promotional markdown rate (%) or cash off amount.
Instantly see the exact money saved and your final payable checkout price.
Discount Amount = Original Price × Discount % ÷ 100
The discount amount is subtracted from the original price to determine the final sale price.
Input: Original Price: ₹1,000, Discount: 20%
Output: Savings: ₹200, Final Price: ₹800
Multiply the original price by the discount percentage and divide by 100.
Final Price = Original Price - Discount Amount.
Yes, the calculator shows both savings and final payable amount.
Yes, it works for all types of discounts and promotional offers.
Enter the original listed price and the advertised discount percentage. The calculator shows the amount saved and the price after that single percentage discount. The currency symbol is for display; the same arithmetic works with any currency when all amounts use one currency.
Discount amount = original price × discount rate ÷ 100. Final price = original price - discount amount. For an item priced at ₹2,000 with a 15% discount, the saving is ₹300 and the final price is ₹1,700.
If a shop applies 20% off and then another 10% off, calculate the second discount on the already reduced price. A ₹1,000 item becomes ₹800, then ₹720. The effective discount is 28%, not 30%.
The result covers one percentage reduction only. Delivery charges, GST or sales tax, fixed-value coupons, cashback, and minimum-order conditions are not included. Check whether tax is calculated before or after the discount when comparing the result with a bill.
