How to Calculate Discount Percentage
The discount percentage formula is straightforward:
Discount % = ((Original Price − Sale Price) ÷ Original Price) × 100
Examples:
- Original: ₹1,000 → Sale: ₹750 → Discount = ((1000−750) ÷ 1000) × 100 = 25% off
- Original: ₹2,500 → Sale: ₹1,500 → Discount = ((2500−1500) ÷ 2500) × 100 = 40% off
- Original: ₹599 → Sale: ₹399 → Discount = ((599−399) ÷ 599) × 100 = 33.4% off
How to Calculate Sale Price from Discount %
Sale Price = Original Price × (1 − Discount% ÷ 100)
- ₹1,200 with 30% off = ₹1,200 × 0.70 = ₹840
- ₹5,000 with 15% off = ₹5,000 × 0.85 = ₹4,250
7 Ways Retailers Trick You with Discounts
1. Inflated MRP (Most Common)
The most widespread trick in Indian retail — especially on e-commerce sites. Products are marked with an artificially high MRP so the "% off" looks impressive. A shoe with actual market value of ₹800 is listed at MRP ₹2,000 with "60% off" at ₹800 — which is just the real price.
How to spot it: Search the same product on multiple platforms. If every platform shows the same "discounted" price, the MRP is likely inflated.
2. Stacked Discounts That Don't Add Up
A 20% discount followed by another 20% coupon does NOT give you 40% off. Each discount applies to the already-reduced price:
- Original: ₹1,000 → 20% off = ₹800 → additional 20% off ₹800 = ₹640
- Total saving: ₹360 = 36% — NOT 40%
3. Charm Pricing — ₹999 vs ₹1,000
Pricing products at ₹499, ₹999, ₹1,999 makes them feel significantly cheaper. Research shows people perceive ₹999 as meaningfully less than ₹1,000 — despite a difference of just ₹1. Always round up mentally when comparing prices.
4. "Up to X% Off" Sales
When a sale advertises "Up to 70% off," only a tiny fraction of products — often the least popular items — carry that maximum discount. The majority of items may be 10–20% off. Always check the actual price of the specific item you want.
5. Buy More to Save More Traps
"Buy 2 get 1 free" = 33% off. "Buy 3 for ₹999" when individual price is ₹350 = only 5% saving. Calculate the per-unit price before being tempted by bundle deals — they're often barely better than individual pricing.
6. Flash Sale FOMO
Countdown timers and "Only 3 left!" labels create artificial urgency. Research shows the same items are often available at the same price after the "sale" ends, or the next flash sale is always around the corner.
7. Cashback vs Instant Discount
A "₹200 cashback" sounds similar to "₹200 off" — but cashback usually comes with conditions: minimum spend, specific payment method, credit to wallet (not bank), and valid only for future purchases. An instant discount is always more valuable.
How to Calculate the Original Price from a Discounted Price
If you're trying to find the original price when you only know the sale price and discount %:
Original Price = Sale Price ÷ (1 − Discount% ÷ 100)
- Paid ₹600 after 25% off → Original = 600 ÷ 0.75 = ₹800
- Paid ₹1,700 after 15% off → Original = 1700 ÷ 0.85 = ₹2,000
Shopping Smarter — Practical Tips
- Track prices before big sales: Check prices 30 days before Amazon/Flipkart sales (use CamelCamelCamel or PriceSpy)
- Compare across platforms: The same product on Amazon, Flipkart, and brand website often has price differences
- Focus on final price, not % off: 50% off ₹1,000 (₹500 savings) is better than 70% off ₹500 (₹350 savings)
- Read coupon terms carefully: Minimum order values often mean you spend more than you save
- Avoid impulse buys during sales: If you weren't planning to buy it, you haven't saved money — you've spent it

Calculate Discount →Frequently Asked Questions
Q: How do I calculate discount in my head quickly?
For 10%: simply move the decimal one place left (₹1,500 → ₹150 off). For 20%: double the 10% figure (₹300 off). For 25%: divide by 4 (₹1,500 ÷ 4 = ₹375 off). For 50%: divide by 2. These mental shortcuts work for quick in-store calculations.
Q: Is GST included in the discounted price?
In India, MRP always includes GST. So when you see a discounted price on a product, the discount is applied to the MRP which already includes GST. You don't pay additional GST on top of the sale price for most retail products. However, for services and online purchases, always check if the displayed price is inclusive or exclusive of GST.
