The Life Insurance Rule of Thumb Most People Get Wrong

Most people are either wildly underinsured or paying for cover they'll never actually need — rarely the right amount. Ask around and you'll hear the same line everywhere: "just take ten times your salary." Ask why, though, and most people go quiet. That's the trouble with rules of thumb. They travel a lot faster than the reasoning behind them, and somewhere along the way the reasoning gets lost entirely.

Where the 10-15x number actually comes from

The logic isn't arbitrary, even if nobody explains it. The idea is simple: if you died tomorrow, your income disappears, but your family's expenses mostly don't. Rent or the home loan EMI keeps coming. School fees keep coming. Groceries, electricity, the works. So the payout has to do the job your salary was doing, for long enough that your dependents can get back on their feet — kids finish school, a spouse re-enters the workforce or adjusts spending, debts get paid down.

Ten to fifteen times your annual income is really just a rough stand-in for "enough years of income replacement plus outstanding debts, minus what you've already saved." Younger earners with small kids and a big home loan often need closer to 15-20x. Someone in their fifties with the mortgage almost cleared and kids nearly independent might need a fraction of that. The multiple was never the point — it's a shortcut for a calculation most people never sit down to actually do.

A quicker way to size it yourself

You don't need a fancy formula, just three numbers:

• Income replacement — how many years your family would need support, times your annual take-home. A rough range is 8-12 years for younger families, less as retirement gets closer.
• Outstanding debts — home loan, car loan, anything that would otherwise fall on whoever's left behind.
• Existing cover and savings — subtract any life insurance you already hold, plus liquid savings and investments that could be used immediately.

Add the first two, subtract the third, and you've got a number that's actually yours instead of borrowed from a rule of thumb. It won't be exact — nothing about this is exact — but it'll be a lot closer than a flat multiple of your salary.

When the rule doesn't apply at all

The standard multiple quietly assumes a fairly typical household: one or two earners, dependents, a home loan, decades left to retirement. Plenty of people don't fit that mould, and for them the rule does more harm than good.

• Single, no dependents, no debt. If nobody relies on your income and there's no loan co-signed in your name, a large life cover mostly just pays a premium for no one's benefit. A smaller cover for final expenses is often enough.
• Dual income, no major debt, healthy savings. If your household could absorb the loss of one income without real strain, the multiple can come down significantly.
• Heavy debt load. A big home loan or business loan pushes the number up past 15x pretty quickly — the debt alone can eat most of a "standard" payout.
• A dependent with special needs. Long-term care costs don't taper off the way a normal income-replacement calculation assumes, so the multiple should be treated as a floor, not a ceiling.
• Near retirement, mortgage cleared, kids independent. At this stage the case for a large term cover often weakens, and the priority shifts toward guaranteed income and a lump sum for the family rather than pure income replacement.

Term cover isn't the only piece

Pure term insurance is usually the cheapest way to get a large income-replacement number, which is why most planners lead with it. But plenty of households also want something that keeps paying out well beyond the working years — a plan that pays regular amounts later in life and still leaves a lump sum behind, rather than cover that simply lapses once the term ends. That's the gap plans like LIC's Jeevan Umang are built for, combining a smaller ongoing payout with a guaranteed sum at the end. If you're weighing that kind of whole-life structure against a plain term plan, running the numbers through the Jeevan Umang calculator is a quick way to see what the payouts actually look like over time, rather than guessing.

Revisit it, don't set it once

The number you land on today has an expiry date, even if nobody tells you that either. A new home loan, a second child, a spouse leaving the workforce to raise kids, a big jump in income — any of these changes the math meaningfully. Most people buy a policy in their late twenties or early thirties and never touch the number again for twenty years, by which point it's often laughably out of step with what their family would actually need. Treat it like a number you check every few years, not a decision you made once and filed away.
