How to Use Discount Calculator Online

  1. Enter the original price of the product
  2. Enter the discount percentage offered by the seller
  3. View the discounted price, money saved, and final price instantly
  4. Use the reverse calculator to find what discount percentage is applied given original and sale price
  5. Add multiple products to calculate total savings across a shopping cart

Discount Calculator Formula & Calculation

Final Price = Original Price × (1 − Discount% ÷ 100) | Original Price (reverse) = Sale Price ÷ (1 − Discount% ÷ 100)

For stacked/successive discounts on two products, each discount is applied independently to its own original price, then the two final prices are compared.

Example: A ₹2,500 shirt at 30% off → Savings = 2,500 × 0.30 = ₹750 → Final price = ₹1,750. Reverse case: a ₹1,750 sale price was reached with a 30% discount → Original price = 1,750 ÷ 0.70 = ₹2,500.

Key Factors That Affect Your Result

  1. Percentage off vs flat amount — A 30% discount is only equivalent to a flat ₹X off at one specific original price; always recompute per item rather than assuming the rupee saving carries over.
  2. Successive discounts — Two discounts applied one after another (e.g., 20% then 10%) do not add up to 30% — the second discount applies to the already-reduced price, giving an effective 28% off.
  3. Reverse calculation use case — Useful for verifying an advertised "original price" on sale tags — multiply the sale price by 100 ÷ (100 − discount%) to check if the claimed original price is genuine.

How Discounts Are Calculated — Flat vs Percentage vs Successive

Frequently Asked Questions

Discount % = ((Original Price – Sale Price) / Original Price) × 100. Example: ₹800 item sold at ₹600 → Discount = (200/800) × 100 = 25%.

Sale Price = Original Price × (1 – Discount%/100). Example: ₹1,000 with 20% off → ₹1,000 × 0.80 = ₹800.

Successive discounts are applied one after another. A 20% discount followed by 10% discount is NOT the same as 30% off. The effective discount = 100 – (80 × 90 / 100) = 28%.

A discount reduces the price at the time of purchase. Cashback is a refund credited after purchase (to your wallet, bank, or card). Both save money but cashback has a delay.

GST is applied on the discounted price (net of discount), not on the original MRP. So if an item is sold at ₹800 after ₹200 discount, GST is charged on ₹800.
