Borrowing is not good or bad in itself. A home loan can build lifelong wealth, while a credit card used carelessly can trap you in debt for years. This guide explains the three most common forms of consumer credit, how they work in India, what the rules say, and how other countries do it. First, what is credit? Credit is money you use today and repay later, with an extra cost called interest. The lender takes a risk that you may not repay, and the interest rate is the price of that risk plus the cost of the money itself. Secured and unsecured credit Every loan falls into one of two groups, and this single difference explains most of the gap in interest rates: Secured credit Unsecured credit Backed by An asset (collateral) – a house, a car, gold, fixed deposits Only your promise to repay and your credit history If you don't repay Lender can take and sell the asset Lender pursues recovery and your credit score suffers Interest rate Lower Higher Examples Home loan, car loan, gold loan, loan against property Personal loan, credit card, most education loans of small amounts Five terms every borrower should know Principal: the amount you borrow. Interest rate: the yearly cost of borrowing, stated as a percentage. It can be fixed (stays the same) or floating (changes with market rates). Tenure: how long you take to repay. EMI (Equated Monthly Instalment): the fixed monthly payment that covers both interest and principal. Credit score: a three-digit number, usually from 300 to 900 in India, that summarises how reliably you have repaid in the past. India has four RBI-licensed credit bureaus – TransUnion CIBIL, Experian, Equifax and CRIF High Mark. Why interest rates are moving now On 7 October 2026, RBI's Monetary Policy Committee raised the repo rate by 25 basis points to 5.50% and changed its stance to "calibrated tightening" – the first hike since February 2023. If you have a floating-rate loan linked to the repo rate, your EMI or tenure may rise at the next reset. Fixed-rate loans are not affected automatically. Personal loans What is a personal loan? A personal loan is an unsecured loan you can use for almost any purpose – a medical emergency, a wedding, home repairs, travel or consolidating other debts. You receive a lump sum and repay it in fixed EMIs, typically over one to five years. How lenders decide Because there is no collateral, the lender relies on three things: your income and job stability, your existing EMIs compared with your income, and your credit score. Salaried employees of large organisations usually get the best rates. Self-employed borrowers and those with thin credit histories pay more. A worked example Suppose you borrow ₹10 lakh at 12% a year for 5 years: Monthly EMI: about ₹22,244 Total repaid over 5 years: about ₹13.35 lakh Total interest paid: about ₹3.35 lakh In other words, the loan costs you one-third extra. That is acceptable for a genuine emergency, but expensive for a holiday. Processing fee: often 1–3% of the loan, deducted upfront, plus GST. Prepayment or foreclosure charges: some lenders charge a penalty if you close the loan early. Insurance bundling: loan protection insurance is sometimes added by default. It is optional – ask. Digital and instant loans in India App-based loans have made credit available in minutes, but they also brought abuse – illegal apps, harassment and hidden charges. RBI's digital lending rules now require that: the loan is given by an RBI-regulated bank or NBFC, and the money goes directly from the lender's account to yours; you receive a Key Fact Statement (KFS) before signing, showing the all-in Annual Percentage Rate (APR) and every fee; you get a cooling-off period to exit the loan by repaying the principal and proportionate interest without penalty; apps cannot access your contacts, photos or files. Red flag If a loan app does not name its RBI-regulated lending partner, asks for access to your contacts, or demands an upfront "processing fee" before disbursing, do not proceed. Report such apps on the RBI Sachet portal or the cybercrime helpline 1930. The global picture United States and United Kingdom: personal loans are common for debt consolidation. Online lenders and peer-to-peer platforms compete with banks. Buy Now, Pay Later (BNPL): short-term instalment credit at checkout grew rapidly worldwide. Regulators in the UK, EU, Australia and the US have moved to bring it under formal consumer-credit rules after concerns about hidden over-borrowing. Emerging markets: in parts of Africa and Asia, very small digital loans on mobile phones are many people's first contact with formal credit – with the same benefits and over-indebtedness risks seen in India. Mortgages (home loans) What is a mortgage? A mortgage is a long-term loan to buy, build or renovate a home, where the property itself is the security. In India it is usually called a home loan. Because it is secured and the amounts are large, interest rates are among the lowest in retail lending, and tenures can stretch to 20–30 years. Key features in India Down payment and Loan-to-Value (LTV): RBI caps how much of the property value a bank can lend – up to 90% for loans up to ₹30 lakh, 80% for loans between ₹30 lakh and ₹75 lakh, and 75% above ₹75 lakh. You pay the rest, plus stamp duty and registration, from your own pocket. Floating rates linked to an external benchmark: most new home loans from banks are linked to the RBI repo rate (External Benchmark Lending Rate). When the repo rate changes, your rate changes at the next reset. No prepayment penalty on floating-rate loans to individuals: you can make part-payments or close the loan early without charges. Tax benefits: under the old tax regime, interest up to ₹2 lakh a year on a self-occupied home (Section 24(b)) and principal repayment within the ₹1.5 lakh Section 80C limit are deductible. These are not available for a self-occupied home under the new regime. Government support: schemes such as Pradhan Mantri Awas Yojana have offered interest subsidies to eligible first-time and lower-income buyers. A worked example A ₹50 lakh home loan at 8.5% for 20 years: Monthly EMI: about ₹43,390 Total repaid: about ₹1.04 crore Total interest: about ₹54 lakh – more than the original loan In the early years, most of each EMI goes towards interest. Even small part-prepayments in the first five to seven years can cut years off the loan and save lakhs in interest. Rule of thumb Many planners suggest keeping total EMIs (all loans together) within about 40% of your take-home pay, and the home loan EMI alone well below that, so that a job change or medical expense does not push you into default. The global picture United States: the 30-year fixed-rate mortgage dominates, supported by government-sponsored enterprises such as Fannie Mae and Freddie Mac. Borrowers can usually refinance when rates fall. United Kingdom: most borrowers take a fixed rate for two or five years, after which they remortgage. This made households very sensitive to the sharp rate rises of 2022–2023. Europe: practices vary widely – long fixed rates are common in Germany and France, while variable rates have been common in Spain and Italy. The 2008 lesson: the global financial crisis began with US "subprime" mortgages given to borrowers who could not afford them, then repackaged and sold worldwide. It is why regulators everywhere, including RBI, now insist on LTV limits, income checks and clear disclosure. Credit cards What is a credit card? A credit card gives you a revolving line of credit with a set limit. You can spend up to that limit, repay in full or in part each month, and spend again. Used well, it is one of the most convenient payment tools available. Used poorly, it is the most expensive form of mainstream credit. India's credit card boom Card usage has grown rapidly. RBI data show the number of outstanding credit cards rose to 124.05 million in August 2026, up from 112.34 million a year earlier, with monthly spending of about ₹2.02 trillion. Spending has stayed around ₹2 trillion a month through 2026, and RuPay credit cards can now be linked to UPI, letting people pay by scanning a QR code on credit. How a credit card bill works Billing cycle: all purchases in a month (say the 1st to the 30th) appear on one statement. Interest-free period: if you pay the full amount by the due date, you pay no interest at all – this can give you up to about 45–50 days of free credit. Minimum Amount Due (MAD): usually around 5% of the bill. Paying only this avoids a late fee, but interest starts on the entire unpaid balance – and new purchases lose their interest-free period. Finance charges: interest on unpaid balances is often around 3–3.75% a month, which works out to roughly 36–48% or more a year. The minimum-due trap On a ₹50,000 balance, paying only the minimum each month can stretch repayment over years and cost you more in interest than the original purchases. If you cannot pay in full, pay as much as possible and stop using the card until the balance is cleared. Converting the balance into an EMI or taking a cheaper personal loan to repay it can also cost less. Your rights under RBI rules RBI's Master Direction on credit and debit cards protects cardholders in several ways: No card may be issued or upgraded without your explicit consent. A request to close a card must be processed within seven working days, provided dues are cleared; delays attract a penalty payable to you. Card issuers cannot add interest on unpaid charges, fees or taxes in a way that compounds them unfairly, and the full charges must be disclosed in a Key Fact Statement. Recovery agents must follow conduct rules – no threats, harassment or calls at unreasonable hours. If a complaint is not resolved within 30 days, you can approach the RBI Ombudsman through the Complaint Management System. Using a credit card wisely Always pay the full amount, ideally through auto-debit. Keep usage below about 30% of your limit – high utilisation can lower your credit score. Avoid withdrawing cash on a credit card: interest starts from day one, plus a fee. Treat rewards and cashback as a bonus, not a reason to spend. Check every statement for unknown transactions and report them immediately. The global picture United States: the most card-dependent major economy. Household credit card debt crossed US $1 trillion in 2023, and the FICO score (300–850) drives most lending decisions. European Union: interchange fees charged to merchants are capped, which keeps rewards modest. Debit cards are more common than credit cards in many member states. China: mobile wallets like Alipay and WeChat Pay largely leapfrogged credit cards, with built-in credit products taking their place. India: credit card penetration is still low compared with the West, but growing fast through co-branded cards, UPI linking and digital onboarding. Side-by-side comparison of credit types Feature Personal loan Home loan Credit card Type Unsecured, fixed term Secured by property Unsecured, revolving Typical use Emergencies, one-time expenses, debt consolidation Buying or building a home Day-to-day spending, short-term cash flow Tenure 1–5 years (sometimes up to 7) Up to 20–30 years No fixed term; monthly bill Cost Moderate to high Lowest Free if paid in full; very high if not Biggest risk Borrowing for wants, not needs Over-stretching on EMI; rate rises Revolving balances and minimum-due trap Regulated by (India) RBI, incl. digital lending rules RBI, NHB for housing finance companies RBI card directions How to choose the right credit Match the loan to the purpose. Long-term assets (a home) suit long-term secured loans. Short-term needs suit short-term credit. Never fund daily expenses with a long loan. Compare the APR, not just the headline rate. The Key Fact Statement shows the true all-in cost, including fees. Borrow only from regulated entities. Verify banks and NBFCs on RBI's website. Check your credit report every year. You are entitled to one free full report annually from each bureau. Correct errors early. Keep an emergency fund. Three to six months of expenses in savings means you will not need expensive credit for every surprise.
