A late payment fee is a penalty charge levied by a credit card issuer or lender when a cardholder or borrower fails to make at least the minimum required payment by the due date specified in the statement — compensating the lender for the cost of following up on overdue accounts, the increased credit risk from delinquent behaviour, and the foregone interest income from non-payment. In India, RBI regulates credit card late payment fees — capping them at ₹1,500 for outstanding balances between ₹100 and ₹10,000 and ₹1,500 for balances between ₹10,001 and ₹25,000, with a maximum fee of ₹1,300 for balances above ₹25,000 under the 2022 RBI Master Directions on Credit Cards. Beyond the fee itself, late payment has serious secondary consequences: the unpaid balance incurs interest charges at the high credit card rate (typically 36% to 48% per annum from the transaction date), the cardholder's credit utilisation ratio deteriorates, and repeated late payments significantly damage the CIBIL score — affecting future loan eligibility and interest rates. For Indian investors and credit card users, setting up auto-debit mandates to pay at least the minimum due amount every month eliminates late payment risk entirely — though paying only the minimum results in rapidly compounding high-interest debt that can spiral into a debt trap. Financial advisors consistently recommend paying the full outstanding balance each month to avoid interest charges entirely while maintaining the benefits of credit card reward points and purchase protection.
