Insurance, Loans and Staying Out of Debt
How EMIs really work, why a minimum-due habit can last fifteen years, and the two kinds of insurance almost everyone needs.
₹50,000 on a credit card, fifteen years to clear
Rohit, 23, put a ₹50,000 holiday on his first credit card and decided to pay only the “minimum amount due” each month, usually 5% of the balance. It felt manageable: about ₹2,500 in the first month, less after that. What he did not work out is that the unpaid balance was being charged 3.5% a month, about 42% a year.
At that pace, paying 5% a month, with a floor of ₹200, it takes more than fifteen years to clear the card, and the interest paid along the way comes to about ₹99,000, nearly twice the original holiday. Nothing about this is hidden; it is printed in the card’s terms. It is simply compounding, from Unit 4, working in reverse. This unit is about borrowing well: when debt helps, when it hurts, how lenders decide what to charge you, and how insurance protects everything else you build.
The minimum-due trap
Assumes 3.5% interest a month (about 42% a year), no new spending, and a ₹200 minimum payment.
Set a balance and how much you repay each month. See how long it takes to clear, and what it costs.
Good Debt and Expensive Debt
Borrowing is not bad in itself. An education loan for a course that raises your earning power, or a home loan you can comfortably repay, can be among the best financial decisions a family makes. Debt becomes dangerous when it is expensive, unplanned, or used for things that lose value quickly, like a holiday or a phone, when it would have been possible to save first.
Secured loans are backed by collateral, such as a house, a car or gold. Because the lender can recover the asset, these loans are cheaper.
Unsecured loans, like personal loans and credit cards, have no collateral, so they cost much more.
Fixed-rate loans keep the same rate for the whole term. Most car loans work this way.
Floating-rate loans move with a benchmark, usually the RBI’s repo rate. Most home loans work this way.
A widely used guard rail is to keep total EMIs below about a third of take-home pay. Above that, a single surprise, such as a medical bill or a lost job, can push a household into missed payments.
How an EMI Works
An equated monthly instalment is a fixed payment that covers both interest and repayment of the loan. Every month, interest is charged on the outstanding balance, and whatever is left of the EMI reduces that balance. Early in a long loan the balance is large, so most of the EMI goes to interest. Later, most goes to repaying the loan itself.
Over twenty years, the family repays the ₹50 lakh plus about ₹54 lakh in interest. That is not a scandal; it is the price of using ₹50 lakh for twenty years. But it explains why prepaying even small amounts early in a loan saves so much interest, and why a lower rate, or a shorter term, matters enormously on long loans.
Fixed, Floating and the RBI
When the RBI raised the repo rate to 5.50% on October 7, 2026, floating-rate home loans linked to it began to reset upwards. On the loan above, a rise from 8.25% to 8.5% adds about ₹790 to the EMI, or the bank keeps the EMI the same and extends the term. A car loan taken at a fixed rate in March did not change at all. New car loans became only slightly dearer: about ₹100 a month on an ₹8 lakh loan over five years.
Neither type is always better. A fixed rate gives certainty, which helps tight budgets. A floating rate falls when the RBI cuts, as it did four times in 2025. The point is to know which one you have, because it decides whether news from the RBI changes your monthly budget.
Your Credit Score
Before lending to you, banks check your credit score, a number between 300 and 900 calculated by credit bureaus such as CIBIL from your repayment history. It answers one question: does this person repay on time? A high score gets you loans faster and at lower rates. A low score can mean rejection, or a much higher rate for years.
Pay every EMI and card bill in full and on time. Payment history matters most.
Use less than about 30% of your card limit.
Do not apply for many loans or cards at once.
Check your report once a year; you can get it free from each bureau.
Insurance: Protecting the Plan
Insurance is not an investment. Its job is to stop one bad event from destroying everything else you have built. You pay a small, certain cost, the premium, to protect against a large, uncertain loss. Two kinds matter more than any others.
Term insurance pays a large sum to your family if you die during the policy term while they depend on your income. It has no maturity payout, which is why it is cheap: a healthy 25-year-old can often get ₹1 crore of cover for well under ₹1,000 a month.
Health insurance pays hospital bills that could otherwise wipe out years of savings or force a family into debt. Employer cover helps, but it ends when the job does, so a personal policy is worth having too.
Since September 22, 2025, premiums on individual life and health insurance are exempt from GST, which made cover about 18% cheaper overnight. Be careful with policies that mix insurance and investment, such as endowment and many money-back plans. They usually provide too little cover and too little return. Buying term insurance and investing the difference separately almost always works out better.
Deep Dive: No-Cost EMI and Buy Now, Pay Later
Shops and apps increasingly offer “no-cost EMI” on phones, laptops and appliances. Sometimes the interest is genuinely absorbed by the seller. Often it is built into the price: the product costs more than it would if paid upfront, or there is a processing fee, or a discount available to cash buyers is quietly dropped. Buy now, pay later apps work similarly and can charge steep late fees.
The test is simple. Compare the total you will pay through EMIs, including fees, with the lowest upfront price you can find. If they are the same, the EMI is genuinely free and only the commitment remains. If not, you are borrowing at a hidden rate. Either way, the EMI counts towards the one-third guard rail, and missing a payment damages your credit score like any other loan.
Case Study: An Education Loan Done Well
Sneha from Vadodara took a ₹6 lakh education loan for a two-year course. She chose a public sector bank because its rate was lower, used the government’s interest subsidy schemes where eligible, and paid the simple interest during the course so that it did not pile up. After graduating she landed a job with ₹40,000 take-home pay and set her EMI at about ₹9,000, well under a third of her pay, over seven years.
She also bought a term policy and a personal health policy in her first month of work, built a three-month emergency fund within a year, and only then started a SIP. Her plan is not unusual or clever. It simply puts the pieces of this course in the right order: protect, then borrow carefully, then build.
