Discount formulas

Price after a discount

Sale price = Original price × (1 − Discount ÷ 100)

Two discounts, one after another

Sale price = Price × (1 − D1 ÷ 100) × (1 − D2 ÷ 100)

Discount percentage from two prices

Discount % = (Original − Sale) ÷ Original × 100

Original price from the sale price

Original price = Sale price ÷ (1 − Discount ÷ 100)

Example: a festive sale

A pair of shoes has an MRP of ₹2,499 and is on 40% off:

  • Sale price = 2,499 × 0.60 = ₹1,499.40
  • You save ₹999.60

Now the site adds an extra 10% off at checkout. The extra 10% applies to ₹1,499.40, not to ₹2,499:

  • Final price = 1,499.40 × 0.90 = ₹1,349.46
  • Total discount = 46%, not 50%

Smart shopping tips

  • Check the MRP. A big discount on an inflated “original price” may not be a real saving. Compare the final price across shops.
  • Stacked offers are smaller than they look. “Up to 70% + extra 20%” is never 90% off.
  • Bank and card offers often have a maximum discount (for example “10% up to ₹1,500”). Work out the cap before you rely on the percentage.
  • Delivery, convenience and platform fees are added after the discount and can eat into your savings.

Discount or cashback — which is better?

A discount lowers the price you pay at checkout. Cashback comes back to you later, often as wallet balance or points with conditions attached. ₹200 off and ₹200 cashback cost the same only if you will definitely use the cashback before it expires. When comparing offers, convert both to the final amount you will actually spend.

Working backwards from a sale price

A shop tag says ₹1,349 after 25% off and you want to know the original price: 1,349 ÷ 0.75 = ₹1,798.67. Choose Original price in the calculator to do this instantly — handy for checking whether a “discounted” price is genuine.

Frequently asked questions

How do I calculate the price after a discount?

Multiply the original price by (100 − discount) and divide by 100. For ₹2,499 at 40% off: 2,499 × 60 ÷ 100 = ₹1,499.40.

Is 50% + 20% off the same as 70% off?

No. The second discount applies to the already-reduced price. ₹1,000 with 50% off is ₹500, and 20% off ₹500 is ₹400 — a total discount of 60%, not 70%.

How do I find the discount percentage from two prices?

Subtract the sale price from the original price, divide by the original price and multiply by 100. MRP ₹1,999 and sale price ₹1,499: (1,999 − 1,499) ÷ 1,999 × 100 = 25% off.

How do I find the original price from the sale price?

Divide the sale price by (1 − discount ÷ 100). If an item costs ₹750 after 25% off, the original price was 750 ÷ 0.75 = ₹1,000.

Is GST included in the discount?

In India, MRP and most retail prices include GST, so the discount applies to the GST-inclusive price. For business quotes that show tax separately, apply the discount first and then add GST with the GST calculator.

What does MRP mean?

MRP is the Maximum Retail Price printed on packaged goods in India. It already includes all taxes, and a shop can’t charge more than the MRP — but it can sell for less, which is where discounts come in.
