Consumer credit is debt incurred to purchase goods and services for personal use. There are two main types: revolving credit like credit cards which can be used repeatedly up to a limit, and installment credit like loans which are paid back in fixed amounts over time. Consumer credit allows consumers to finance purchases even when funds are low and helps raise living standards, but it can also lead to overspending and long-term financial problems if not managed carefully. The consumer credit industry in India is growing as incomes rise, but more education is still needed about options and responsible use.
