How to Calculate Real Discounts and Avoid Fake Sales

Amazon's "70% off" might actually be 20% off the usual price. Here is how to calculate real discounts and spot inflated MRPs.

1.The MRP inflation trick

Online marketplaces often inflate the MRP before applying discounts. A ₹999 t-shirt has an "MRP" of ₹2,499 — "60% off!" The actual market price (what most stores sell it for) is ₹999-1,199. The real discount is 0-16%. How to verify: check the same product across Amazon, Flipkart, and the brand's own website. The lowest consistent price is the true market price. Use price tracking tools like PriceHistory.in for Indian e-commerce.

2.Double and triple discount math

Sale: "Additional 20% off on 30% discounted price." This is NOT 50% off. It's: ₹1,000 × (1 − 0.30) × (1 − 0.20) = ₹1,000 × 0.70 × 0.80 = **₹560**. Effective discount: 44%, not 50%. Similarly, "Buy 2 Get 1 Free" on ₹500 items = ₹1,000 for 3 items = ₹333 each = **33.3% discount** per item (not "free"). Understanding the math prevents impulse buying based on misleading discount language.

3.When discounts are genuine: Indian sale seasons

Genuinely good discount periods: **Flipkart Big Billion Days** (October) and **Amazon Great Indian Festival** (October): electronics are 15-25% below usual prices. **End-of-season sales** (January, July): fashion brands offer genuine 30-50% off to clear inventory. **Republic Day / Independence Day sales**: appliances and furniture have real discounts. Credit card and bank offers stack on top — an additional 10% instant discount on SBI/HDFC cards is common.

4.Key takeaway

Never trust the "% off" displayed on the listing. Calculate the discount yourself: (MRP − Sale Price) ÷ MRP × 100. Compare across platforms and track price history. Use our discount calculator to quickly find the final price and real savings on any purchase.
