How to calculate discount percentage

There are three common discount calculations you might need:

Find the sale price: Sale Price = MRP × (1 − Discount% ÷ 100)
Find the discount %: Discount% = (MRP − Sale Price) ÷ MRP × 100
Find the original price: MRP = Sale Price ÷ (1 − Discount% ÷ 100)

Comparison table

The built-in comparison table shows what the same item costs at 5%, 10%, 15%, 20%, 25%, 30%, 40%, and 50% off — useful for quickly evaluating whether a promotional discount is worth it or comparing offers across multiple stores.

Tips for smart shopping

Watch out for inflated MRPs — some sellers raise the MRP before applying a large-looking discount. Compare the absolute price across platforms.
Successive discounts aren’t additive— “20% + 10% extra” is only 28% off, not 30%.
Include delivery charges — a 30% discount can be wiped out by high shipping fees on low-value orders.

Who uses a discount calculator

Shoppers use it during sale events like Amazon Great Indian Festival, Flipkart Big Billion Days, and Myntra End of Reason Sale to verify whether the advertised discount is genuine and to find the true price after stacked coupon codes. Small business owners calculate net margin after offering customer discounts — a 20% discount on a product with a 25% margin leaves only 5% profit. Retail store managers use it to price clearance items at specific discount levels. Students doing competitive exam preparation for aptitude tests use it to practise percentage-based pricing problems.

Successive discounts — the correct calculation

Many e-commerce platforms advertise “extra 10% off on top of 30% off.” These do not add up to 40%. The correct formula: Final Price = Original × (1 − D1/100) × (1 − D2/100). For a 30% + 10% successive discount: Final = Original × 0.70 × 0.90 = 0.63 × Original — meaning the effective discount is 37%, not 40%. This calculator handles single discounts; for stacked discounts, apply the calculation in two steps using the output of the first as the input to the second.

MRP regulations in India

The Legal Metrology (Packaged Commodities) Rules, 2011 require all pre-packaged goods sold in India to display the Maximum Retail Price inclusive of all taxes. Selling above MRP is a violation penalised under the Act. Online marketplaces are required to display MRP and the discounted price clearly. The Central Consumer Protection Authority (CCPA) has issued guidelines against misleading discount claims — including artificially inflating MRP before applying a large-looking percentage discount. Use this calculator to check whether the absolute discount value matches the advertised percentage.

Frequently asked questions

How do I calculate a discount?

Discounted Price = Original Price × (1 − Discount% ÷ 100). For example, a 20% discount on ₹1,000 gives ₹1,000 × 0.80 = ₹800. Amount saved = ₹1,000 − ₹800 = ₹200.

How do I find the original price from a discounted price?

Original Price = Sale Price ÷ (1 − Discount% ÷ 100). For example, if an item costs ₹800 after a 20% discount, the original price is ₹800 ÷ 0.80 = ₹1,000. Use the 'Find original price' mode in this calculator.

What is the difference between discount and cashback?

A discount reduces the price upfront at the time of purchase. Cashback is a refund credited back to your account after the purchase, usually with conditions (minimum spend, specific payment method, etc.). The effective saving is the same only if the cashback is unconditional and instant.

How do successive discounts work?

Successive discounts (e.g., 20% then 10%) do not simply add up to 30%. The second discount applies to the already-reduced price. Formula: Final Price = Original × (1 − D1/100) × (1 − D2/100). A 20% + 10% successive discount gives 1 − 0.8 × 0.9 = 28% effective discount — not 30%.

What is MRP and how does it relate to discounts?

MRP (Maximum Retail Price) is the highest price at which a product may legally be sold to end consumers in India, the Legal Metrology Act. Discounts are calculated on MRP. Selling above MRP is illegal. Online platforms and stores often offer discounts ranging from 5% to 80% off MRP during sales.
