How Much Life Insurance Do I Need? Two Methods Explained

Why Most Indians Are Underinsured

IRDAI data consistently shows that the average sum assured per policy in India is around ₹4–₹6 lakh — a figure that would sustain a family for less than a year at median urban living costs. The gap between what people own and what they need is enormous. This is partly because insurance has historically been sold as a savings product (endowment plans, ULIPs) rather than pure protection, and partly because most people choose a cover amount based on gut feel rather than a structured calculation.

Two methods give you a defensible number: the Human Life Value (HLV) method and the Income Replacement method. Use both, then take the higher figure.

Method 1 — Human Life Value (HLV)

The HLV approach treats your earning potential as an asset and calculates the present value of your future income stream. The concept: if you were a financial instrument, how much would an investor pay today to receive your income until retirement?

Formula (simplified):

HLV = Annual Income × (1 − Tax Rate) × [1 − (1 + g)^n / (1 + r)^n] / (r − g)

Where:

• g = expected annual income growth rate
• r = discount rate (typically 7–8%, the long-term debt return)
• n = working years remaining until retirement

Worked example — Priya, 34:

• Annual income after tax: ₹12 lakh
• Income growth rate: 8% per year
• Discount rate: 7.5%
• Working years remaining: 26 (retiring at 60)

At these inputs, the HLV comes to approximately ₹3.2 crore. This represents the lump sum, invested at 7.5%, that would replicate Priya's income stream for 26 years. This is the theoretical minimum her family needs to maintain their standard of living.

Method 2 — Income Replacement Method

Simpler and more intuitive. Estimate how many years of income your family needs to replace, then add specific liabilities.

Formula: Cover = (Annual expenses × Years of replacement) + Outstanding debts + Specific future obligations

Worked example — Priya continued:

Priya should subtract existing assets (EPF balance ₹18 lakh, FD ₹5 lakh) to arrive at her net cover need of ₹2.62 crore. Rounding up to ₹3 crore gives a comfortable margin.

Comparing the Two Results

Take the higher of the two figures. In Priya's case that is the HLV result. Buying ₹3 crore of term cover costs her roughly ₹900–₹1,100 per month online — less than ₹35 per day.

Adjusting for Existing Cover

Before buying, tally up what you already have:

• Group life cover from employer: typically 3–4x annual salary; it lapses if you change jobs
• Existing individual policies: sum assured from all active life policies
• Spouse's income: if your partner earns, the income replacement need is lower

Do not count employer group cover as permanent protection. It is a conditional benefit. Include it as a temporary buffer at most.

Common Mistakes That Leave Families Underinsured

Mistake 1 — Picking ₹1 crore because it sounds like a round number. Without a calculation, ₹1 crore is just a number. Run the math first.

Mistake 2 — Forgetting inflation on future obligations. ₹20 lakh for a child's education today could be ₹40 lakh in 15 years at 5% education inflation. Use future values, not today's costs.

Mistake 3 — Assuming the surviving spouse will not grieve productively for years. Financial planners add a 1–2 year buffer for the family to reorganise. Build that into your replacement period.

Mistake 4 — Ignoring stay-at-home partner contributions. A non-earning spouse provides childcare, household management, and elder care worth ₹3–₹5 lakh per year in market value. They need term cover too — ₹50–₹75 lakh at minimum.

Mistake 5 — Not increasing cover after major life events. Cover adequate at 28 is rarely adequate at 38. Revisit after marriage, home purchase, childbirth, or a large salary increase.

How to Buy the Right Amount Without Overpaying

Once you have a target cover figure, compare 3–4 online term plans on aggregator sites like PolicyBazaar or Ditto. Filter for:

1. Claim settlement ratio above 98% (IRDAI Annual Report)
2. Solvency ratio above 1.5 (IRDAI requirement is 1.5; higher is safer)
3. Premium within your budget for the full desired term

Do not split across more than two insurers unnecessarily — the administrative complexity is rarely worth it unless your cover need exceeds ₹5 crore (where a single insurer may decline the full amount).

The Takeaways

• The HLV method calculates the present value of your future earning stream; income replacement adds up expenses, debts, and future costs — take the higher of the two.
• For most urban Indians with dependants, the number lands between ₹1.5 crore and ₹4 crore.
• Subtract existing assets and permanent cover to get your net shortfall — that is what you need to buy.
• Employer group cover lapses when you leave the job; never rely on it as your primary protection.
• A stay-at-home partner also needs term cover — their economic contribution is real even without a salary.
• Revisit your cover calculation every 5 years and after every major life event.
