No, not universally. EMI conversion is commonly available for larger purchases at partnered retailers, electronics, furniture, travel bookings, and similar categories, but many banks exclude certain transaction types entirely, such as some cash-equivalent purchases, government payments, or transactions below a minimum threshold amount. Whether a specific purchase qualifies generally depends on both the retailer's participation in an EMI programme and the bank's own eligibility rules for that transaction category, so checking eligibility at the time of purchase is more reliable than assuming it will qualify.
