Discount Formulas — Quick Reference

Sale Price

Price × (1 − d/100)

e.g. 2000 × (1 − 25/100) = ₹1500

Discount %

((MRP − Sale) ÷ MRP) × 100

e.g. ((1200 − 900) ÷ 1200) × 100 = 25%

Original Price

Sale ÷ (1 − d/100)

e.g. 1500 ÷ 0.75 = ₹2000

Double Discount

(1−d₁/100) × (1−d₂/100)

e.g. 30% + 10% → 0.7 × 0.9 = 37% off

What Is a Discount?

A discount is a reduction from the original price (often the MRP — Maximum Retail Price) of a product or service. It is usually expressed as a percentage, such as "25% off", but it can also be a flat rupee amount. The price you actually pay after the discount is called the sale price or net price, and the gap between the MRP and the sale price is your savings.

Worked Example

Suppose a jacket is priced at ₹2,000 with a 25% discount. The discount amount is 2,000 × 25 ÷ 100 = ₹500. So the sale price is 2,000 − 500 = ₹1,500, and you save ₹500. If the store then offers an extra 10% off at checkout, that 10% applies to ₹1,500 (not ₹2,000), removing another ₹150 — giving a final price of ₹1,350 and an effective discount of 32.5%, not 35%.

Why It's Useful

  • Instantly check whether a "sale" is as good as it looks before you buy.
  • Compare two offers — e.g. "40% off" versus "30% + extra 10%".
  • Work backwards to verify the original price retailers claim.
  • Plan budgets and big-billing-day (festive sale) shopping.

Frequently Asked Questions

Common discount and sale price questions

How do I calculate a discount on a price?
Multiply the original price by the discount percentage, then divide by 100 to get the discount amount. Subtract it from the original price for the final price. Final Price = Price × (1 − Discount% ÷ 100). Example: a ₹2,000 item at 25% off = 2,000 × 0.75 = ₹1,500, saving ₹500.
How do I find the discount percentage from two prices?
Discount % = ((Original Price − Sale Price) ÷ Original Price) × 100. Example: an item marked ₹1,200 selling for ₹900 → ((1200 − 900) ÷ 1200) × 100 = 25% off.
How do I find the original price before a discount?
Original Price = Sale Price ÷ (1 − Discount% ÷ 100). Example: you paid ₹1,500 after a 25% discount → 1,500 ÷ 0.75 = ₹2,000 original price.
Is "30% + extra 10%" the same as 40% off?
No. Successive discounts apply one after another, not added together. A 30% then 10% discount means 0.70 × 0.90 = 0.63, i.e. an effective 37% off — not 40%. On ₹1,000 you pay ₹630, not ₹600.
Is GST charged before or after the discount?
Under Indian GST, tax is normally charged on the discounted (net) price when the discount is shown on the invoice. So a ₹1,000 item at 20% off has GST applied on ₹800, not ₹1,000. Use the GST Calculator to add tax on the sale price.
