A deep dive into pricing psychology and math to determine when a flat amount off saves you more money than a percentage off.
When you're shopping and spot two different promotions—say, "₹500 Off" vs. "30% Off"—which one is the better deal? The answer entirely depends on the original price of the item. Use our Discount Calculator to compare them instantly.
The Rule of 100
In marketing psychology, there is a concept known as the "Rule of 100." It dictates how retailers choose to frame their discounts to make them seem as large as possible to the consumer:
- If the price is under 100 (in your local currency): Percentage discounts look larger. (e.g., "25% off a ₹40 item" sounds better than "₹10 off," even though they are exactly the same).
- If the price is over 100: Flat amount discounts look larger. (e.g., "₹300 off a ₹1,000 item" sounds better than "30% off," even though they are exactly the same).
Doing the Math
To find out which is truly better for your wallet, you must compare them directly.
Scenario A: Buying a ₹5,000 Jacket
Offer 1: ₹1,000 Off (Flat)
Offer 2: 25% Off (Percentage)
Calculation: 25% of ₹5,000 = ₹1,250.
Winner: The Percentage Discount saves you ₹250 more.
Scenario B: Buying a ₹1,500 Book
Offer 1: ₹500 Off (Flat)
Offer 2: 25% Off (Percentage)
Calculation: 25% of ₹1,500 = ₹375.
Winner: The Flat Discount saves you ₹125 more.
Beware of Minimum Purchase Requirements
Often, flat discounts come with a catch: "₹500 Off on orders above ₹2,000." If you only planned to spend ₹1,000, adding another ₹1,000 of unwanted items just to save ₹500 means you are still spending ₹1,500 more than you intended. In these cases, a straight percentage discount with no minimum is usually superior.
Stacked Discounts
Things get tricky when discounts stack (e.g., "Take an extra 10% off already reduced prices"). The second discount applies to the new, lower price, not the original price. 20% off plus 10% off is a 28% effective discount, not 30%.
