How Much Term Insurance Do You Actually Need?
Thumb rules like '10x your income' can leave your family badly short. Here is the four-number method that produces a defensible cover amount.
Ask an agent how much term cover you need and you will hear a thumb rule: ten times your annual income. It fits in a sentence, requires no thought, and is wrong often enough to be dangerous - too little for a 28-year-old with young kids and a home loan, wastefully high for a 55-year-old with a built-up corpus and no dependents.
Your family does not experience your income after you are gone. They experience your expenses, your debts, and your promises. Those are the things insurance must replace, so those are the things you should count.
The four numbers that matter
1. Living expenses, inflated, until retirement age
Start with what your household spends annually. Now project it forward - not flat, but growing with inflation - for every year until you would have retired. This is the number thumb rules butcher: at 5.5% inflation, ₹8.4 lakh of annual expenses today is over ₹31 lakh a year by year 25.
Summed across 25 years, a household spending ₹8.4 lakh today needs roughly ₹4.3 crore of expense replacement. Not intuition-friendly, which is exactly why it needs calculating rather than guessing.
2. Future goals you have already promised
A child's higher education. A wedding. A parent's care. If the plan was "we will fund it from future income," insurance must stand in for that future income. Put a present-value number on each promise and add them up.
3. Outstanding loans
Every loan you hold becomes your family's loan the day you are gone. Home loan, car loan, personal borrowing - add the full outstanding balances. A ₹6 lakh loan balance means ₹6 lakh of extra cover, rupee for rupee.
4. Minus what is already covered
Subtract existing term policies and employer group cover you genuinely expect to persist - though treat employer cover skeptically, since it vanishes with the job. Subtract investments large enough to be genuinely deployable (not the emergency fund, not the house they live in).
The formula, in one line
Cover = inflated living expenses till retirement + goals + outstanding loans - existing cover and deployable corpus
Worked example: ₹8.4 lakh annual expenses, age 25, retiring at 50, 5.5% inflation, ₹20 lakh of future goals, ₹6 lakh of loans, ₹1 crore existing cover. Required cover: ₹3.56 crore. Against the "10x income" rule for someone earning ₹12 lakh - ₹1.2 crore - the thumb rule leaves a ₹2.3 crore hole.

Three mistakes that quietly gut a good policy
Buying investment-flavored insurance. Endowment, money-back, and ULIPs bundle weak investing with thin cover. For the premium of a ₹25 lakh endowment plan you can typically buy ₹2-3 crore of pure term cover and invest the difference in a SIP - ending up better on both fronts.
Insuring the non-earner heavily while under-insuring the earner. Cover follows income dependency, not affection.
Setting and forgetting. A policy sized before a home loan and a second child is undersized after them. Re-run the numbers at every major life event - marriage, each child, every big loan - and top up with a fresh policy when the gap grows.
When to let cover lapse
Term insurance is a bridge, not a permanent fixture. The day your investment corpus can fund your family's inflated expenses and remaining goals on its own - what the FIRE crowd calls being self-insured - extra cover becomes an unnecessary expense. Until that day, it is the cheapest guarantee your family's plan survives you. You can estimate when that self-funded point arrives with our Power Age Calculator.
