How much term cover you actually need — the income-multiple, the debt-haircut, and the dependent line
Bishan Kumar Agarwal
The rule-of-thumb says 10× annual income. It is the number on every term insurance brochure in India, and it is wrong for most families. It ignores outstanding debt, ignores the time to dependent self-sufficiency, and assumes uniform inflation across a 30-year horizon. Here is the actual math.
Getting the number right matters because term cover is inexpensive relative to its impact. A ₹2 Cr policy costs a 35-year-old nonsmoker roughly ₹18,000–22,000 per year. Getting the number wrong — either too low or overblown — is a planning error, not a cost error.
The base income-replacement model
The right starting point is: how much capital, invested at a safe withdrawal rate, would replace your income in perpetuity? The safe withdrawal rate for a mixed Indian portfolio (debt + equity) is approximately 4–5%. That means:
- At 4% SWR: 25× annual income to fully replace earnings
- At 5% SWR: 20× annual income
So the brochure's 10× covers roughly half of what is actually needed for full perpetual replacement. The reason most families can get by with less is that they do not need perpetual replacement — dependents become self-sufficient over time, reducing the coverage obligation.
Adjust for debt: home loan, education loan, car
Outstanding debt is a liability that must be cleared immediately on death — it does not wait for the replacement-income model to fund it over time. Add the current principal outstanding on all loans to the base income-replacement number:
- Home loan outstanding: ₹X (most common and largest)
- Personal or education loan: ₹Y
- Car loan: ₹Z (lower priority — sell the car if needed)
Total cover target so far = (income × multiplier) + outstanding debt.
Adjust for dependents: spouse income, children's age
If your spouse earns, their income partially offsets the cover need. Subtract the present value of their expected earnings over the dependency period. If your children are 5 and 8, they may become financially independent in 15–20 years — so the full income-replacement cover is only needed for that window. After that, the surviving household needs only enough for a single adult lifestyle.
10× annual income is what a brochure says. 14× minus the future co-earner contribution is what a family actually needs.
Adjust for inflation horizon
The income-replacement need decays as dependents age out. The full-replacement cover you need today shrinks to a smaller lifestyle-maintenance number as the years pass. This is why longer-tenor policies (30-year) justify larger sums assured — you are covering a longer dependency window.
Worked examples: three Indian households at different stages
Household A: 33-year-old IT professional, two young children, active home loan
Annual income ₹18L. Spouse earns ₹8L. Home loan outstanding ₹40L. Children ages 4 and 7. Dependency horizon: 18 years. Practical target: (₹18L × 14) + ₹40L − PV of spouse income = approximately ₹2.3 Cr.
Household B: 42-year-old business owner, one child in college, no home loan
Annual income ₹30L. Spouse not working. Child is 19 and self-sufficient in 3 years. Dependency horizon: short. Practical target: (₹30L × 10) + business succession buffer = approximately ₹3.5 Cr.
Household C: 29-year-old salaried, unmarried, dependent parents
Annual income ₹12L. Both parents retired and dependent. Cover horizon: 25 years. Practical target: (₹12L × 18) + parents' medical and housing buffer = approximately ₹2.2 Cr.
In each case, the 10× rule either undershoots significantly or ignores the most important variable (dependent type and horizon). A 12–18× multiple for most middle-income families with 2 dependents and an active home loan is the reasonable working range.

Health-insurance buffers don't belong here
Don't add health-insurance sub-limit-style buffers to your term cover calculation. The math is different — term cover is income replacement, not medical cost coverage.
Joint life vs single life policies
Joint policies look cheaper per rupee of cover but typically pay out only once (on first death). Two separate single-life policies often provide better combined coverage for a dual-income household.
Inflation index riders cost 30%+
A rider that grows the sum assured with inflation adds 30%+ to the premium. Only worth considering on policies with 25+ years to maturity — on shorter tenors, the math does not support the cost.
Critical-illness riders are a separate conversation
A CI rider attached to a term policy is a health-side product bundled onto a life product. Evaluate it on its health merits, not as part of the core life-cover calculation.

- What if my income grows faster than 6%?
- The income-replacement model is a snapshot calculation at the time of purchase. If your income grows significantly, your cover becomes relatively smaller over time. The right response is either to buy a larger sum assured upfront (if affordable) or to add a separate policy as your income grows — a practice called term stacking. Revisit your cover calculation every 5 years or at major life events.
- Does the math change if my spouse is the higher earner?
- Yes, in two directions. First, the primary breadwinner's cover should be sized to the larger income — which is now your spouse's. Second, your own cover is sized to replace your income, which is smaller. The household calculation still works the same way; just apply it to each life independently and check that the combined cover is sufficient for the dependent obligations.
- Should I buy a single 30-year policy or two 20-year policies?
- Two-policy structuring (e.g. one 20-year and one 30-year) costs slightly more in total but lets you drop the shorter policy when your dependents are self-sufficient, reducing premium outgo in later years. The 30-year single-policy approach is simpler. The right answer depends on your income growth trajectory, when your dependents become independent, and whether you prefer simplicity or optimisation.
