💡 Real-Life Example: Meet Ravi, a High-Spender in Mumbai

Ravi, a marketing executive, spends roughly ₹1.5 lakh monthly on groceries, dining, and fuel. With a Citi Custom Cash card, he earns 5% on his highest spending category — usually groceries — and 1% on the rest.

He also uses the Amex Blue Cash Preferred for gas station and supermarket shopping. Over a year, he earns close to ₹45,000 in cash back by aligning his expenses with card reward categories. That’s real money back on spending he’d already do!
