What is a Discount?

A discount is a reduction applied to the original price of a product or service, usually expressed as a percentage. It lowers the amount you actually pay — the sale price — and the money you keep is your savings. Discounts appear everywhere: festive sales, clearance offers, coupon codes, bulk deals and loyalty rewards. This calculator instantly works out both the discount amount and the final price from the original price and the discount rate.

How is a Discount Calculated?

A discount is calculated with two simple formulas:

Discount = (Original Price × Discount Rate) ÷ 100
Sale Price = Original Price − Discount

The discount rate is the percent-off, the discount is the money saved, and the sale price is what you actually pay at checkout.

Worked Example

Suppose a jacket is priced at ₹2,000 with a 25% discount:

  • Discount = (2,000 × 25) ÷ 100 = ₹500
  • Sale Price = 2,000 − 500 = ₹1,500

You save ₹500 and pay ₹1,500. Toggle the calculator to Excluding Discount mode to run this yourself.

Finding the Original Price from a Sale Price

When only the discounted price is shown, you can work backwards to the original price — a reverse discount:

Original Price = Sale Price ÷ (1 − Rate ÷ 100)

Example: a shirt costs ₹800 after a 20% discount. Original Price = 800 ÷ (1 − 0.20) = 800 ÷ 0.80 = ₹1,000. Use the Including Discount mode in the calculator to reveal the pre-discount price from a discount-inclusive amount.

Double or Stacked Discounts

Two discounts applied one after another do not add up. A 20% discount followed by a 10% discount is not 30% off — each cut is calculated on the price left after the previous one:

  • Start: ₹1,000
  • After 20% off: ₹1,000 − ₹200 = ₹800
  • After 10% off ₹800: ₹800 − ₹80 = ₹720

The effective discount is 28%, not 30%. To model stacked offers, run the calculator twice, feeding the first sale price back in as the new original price.

Discount vs Markup

A discount reduces a selling price and is calculated on the higher, original price. A markup increases a cost and is calculated on the lower, original cost. Because the base differs, equal percentages do not cancel: ₹100 marked up 20% is ₹120, but 20% off ₹120 is ₹96 — not ₹100. Keep this in mind when converting between cost, markup and sale price.

Frequently Asked Questions

How do I calculate a discount?
Multiply the original price by the discount rate and divide by 100 to get the discount amount: Discount = (Price × Rate) ÷ 100. Subtract that from the original price to get the sale price. For example, 20% off ₹1,000 is a ₹200 discount, so you pay ₹800.
What's the difference between percent-off and final price?
The percent-off is how much you save as a proportion of the original price (the discount rate). The final price, or sale price, is what you actually pay after that saving is deducted: Sale Price = Price − Discount. A 25% discount on ₹2,000 saves ₹500 and gives a final price of ₹1,500.
How do I find the original price from a sale price?
Divide the sale price by (1 − rate/100). If an item costs ₹800 after a 20% discount, the original price was ₹800 ÷ (1 − 0.20) = ₹800 ÷ 0.80 = ₹1,000. This is called a reverse discount and is handy when only the discounted price is shown on the tag.
How do two stacked discounts work?
Stacked discounts apply one after another, not by adding the percentages. A 20% discount followed by a 10% discount is not 30% off. On ₹1,000, the first cut gives ₹800, then 10% off ₹800 gives ₹720 — an effective discount of 28%, not 30%.
What is the difference between a discount and a markup?
A discount reduces a price and is calculated on the original (higher) price, while a markup increases a cost and is calculated on the original (lower) cost. Because the base differs, a 20% markup and a 20% discount do not cancel out: ₹100 marked up 20% is ₹120, but 20% off ₹120 is ₹96, not ₹100.
How do I calculate the discount percentage from two prices?
Subtract the sale price from the original price, divide by the original price, then multiply by 100: Rate = ((Price − Sale Price) ÷ Price) × 100. An item down from ₹2,500 to ₹2,000 has a discount of ((2500 − 2000) ÷ 2500) × 100 = 20%.
