Ask five people how much term insurance they need and at least four will say some version of "10 to 15 times my annual salary." It's the most repeated rule of thumb in Indian personal finance — and it's also a coin-flip guess dressed up as a formula, because it ignores the two things that actually determine how much your family would need: what you owe, and how many years they'd need support without your income.
Why a flat multiple breaks down in practice
Consider two people, both earning ₹12 lakh a year. One is 28, single, no loans, parents financially independent. The other is 42, has a ₹40 lakh home loan with 12 years left, two kids under 10, and a non-earning spouse. A flat "12x salary" rule gives both the same ₹1.44 crore cover — despite the second person's family facing a dramatically larger financial gap if something happened to them. The multiple approach can't tell these two situations apart because it was never built to.
The Human Life Value method: four steps
This is the approach actuaries actually use to estimate how much income-replacement cover a person needs. It has four components, and you add the first three, then subtract the fourth.
Step 1: Income replacement for your remaining working years
Take your annual income, subtract what you personally spend on yourself (since that expense disappears too), and multiply the remainder by the number of years your family would need that support — typically until your youngest child becomes financially independent, or your own expected retirement age, whichever is sooner.
Step 2: Add outstanding liabilities
Every loan that wouldn't disappear on its own — home loan, car loan, personal loan — gets added in full, since these become your family's obligation, not a future expense to plan for gradually.
Step 3: Add future one-time goals
Children's higher education, a wedding fund, or any other large future cost you're currently planning to fund from future income rather than existing savings.
Step 4: Subtract existing assets and cover
Existing savings, investments, and any insurance you already hold reduce the gap — this is the step the "10x salary" rule skips entirely, which is exactly why it tends to over- or under-insure people who already have some savings built up.
A full worked example
Take the 42-year-old from earlier: ₹12 lakh annual income, spends roughly ₹3 lakh on personal expenses, 12 years until the younger child turns 21.
| Component | Calculation | Amount |
|---|---|---|
| Income replacement | (₹12L − ₹3L) × 12 years | ₹1.08 crore |
| Outstanding home loan | As stated | ₹40 lakh |
| Future education/wedding goals | Estimated combined | ₹35 lakh |
| Subtotal | Sum of above | ₹1.83 crore |
| Less existing savings + insurance | Subtract | − ₹25 lakh |
| Recommended cover | ≈ ₹1.58 crore |
That's meaningfully higher than the "12x salary" flat rule (₹1.44 crore) despite starting from the same income — because this person's debt and goals genuinely require more, and no flat multiple would have caught that automatically.
Where people usually get this wrong
- Forgetting to subtract existing assets, leading to needless over-insurance and higher premiums than necessary.
- Using current age instead of years of dependency — someone withhttps://www.calkar.in/2026/06/emi-calculator.html young kids needs a much longer replacement window than someone whose kids are about to graduate, even at the same income.
- Ignoring loan tenure mismatches — if your term cover ends before your home loan does, there's a real gap in the years between.
FAQs
Is the "10x salary" rule completely useless?
Not useless — it's a reasonable starting estimate if you have no
major debt and roughly average dependents. It just shouldn't be
the final number for anyone with significant loans or a longer
dependency period.
Should term insurance cover reduce as I get older?
Often yes, in principle — your remaining income-replacement years
shrink and your loans get paid down. Some insurers offer
reducing-cover term plans for exactly this reason, though a level
cover plan is simpler to manage even if slightly costlier over
time.
