Ask ten people how much term insurance they have, and eight will give you a round number — fifty lakh, one crore, two crore. Ask why that number instead of another, and most will say a colleague has the same cover, or an agent suggested it. That isn’t a plan; it’s a guess with a premium attached. This piece answers the two questions that guess is standing in for: how much term insurance do you need, and once you know that number, what actually drives what you’ll pay for it.
A round number is comfortable because it doesn’t ask anything of you. Working out your actual cover requirement does — it asks you to look at your income, your debts, your dependents’ timeline, and what you’d want your family’s life to look like if you weren’t there to earn. Most people skip that exercise entirely and let an agent’s suggested figure, or whatever a friend bought, stand in for it. The result, almost every time, is either meaningful under-insurance dressed up as a tidy number, or an unnecessarily expensive policy nobody needed that large. Neither is a plan. This article walks through the actual arithmetic — the methods planners use, a full worked example, and then the flip side: once you know your number, what specifically makes one person’s premium for that number so different from another’s.
How Much Term Insurance Do You Need?
There is no single official formula, but three methods dominate how financial planners and insurers actually approach this question. Each answers a slightly different version of “what would my family need,” so the honest approach is to use more than one and let them cross-check each other.
The simplest and most commonly cited approach: multiply your annual income by 10 to 15. The logic is that the payout, conservatively invested, should be able to replace a meaningful share of your income for a decade or more while your family adjusts and rebuilds. It’s a reasonable starting point, but it says nothing about your specific debts or goals — which is exactly what the next two methods correct for.
Add up what your family would actually need to stay financially whole: outstanding loans (home, car, personal) that shouldn’t fall on them, your children’s future education and marriage costs in today’s rupees, and enough of a corpus to cover household expenses until your spouse or dependents reach financial independence. Then subtract what you already have earmarked for these — existing savings, other insurance, assets that could be liquidated. What’s left is the gap your term cover needs to close.
The method insurers and actuaries lean on most: it estimates the present value of your future earnings across your remaining working years, discounted to today’s rupees, minus your own likely future expenses. Because it accounts for how many earning years you have left, it naturally produces a higher multiple of income for someone in their late twenties than for someone approaching fifty — which is also why online term calculators ask for your age even before your income.
Worked Example: Calculating Your Own Number
Numbers land better with a real scenario. Here’s Method 2 — expense and liability replacement — worked through step by step, since it’s the version most people can actually reproduce with their own figures.
Notice what this number is not: it isn’t the sum assured a bank relationship manager quoted, and it isn’t what a colleague on a similar salary happens to hold. It’s specific to this person’s loans, goals, and existing assets — which is exactly why two people earning the same income can genuinely need very different amounts of cover, and why copying someone else’s number is close to meaningless.
This figure isn’t permanent. A new home loan, a second child, a spouse leaving the workforce, or a big jump in income are all reasons to recalculate — usually by adding a fresh term policy or a top-up rather than surrendering and re-buying the original one, since your original premium was locked in at a younger, cheaper age.
What Drives Term Insurance Premium
Once the cover amount is settled, the premium for that exact same cover can still vary sharply — sometimes by 40% or more — from one applicant, or one insurer, to the next. Here’s what’s actually doing that work behind the quote.
- Age at purchase: The single biggest lever. Premiums are locked in largely by your age and health when you buy, so the same cover bought at 45 instead of 25 can cost several times more — and that gap compounds because you’re also insuring for fewer remaining years at the older age.
- Gender: Insurers generally price women slightly lower than men for identical cover, reflecting statistically longer average life expectancy and lower mortality risk in the underwriting tables.
- Tobacco and smoking status: Declared smokers typically pay a meaningfully higher premium than non-smokers for identical cover, reflecting higher mortality risk. Under-declaring this is one of the most common reasons claims get contested later — it’s rarely worth the short-term saving.
- Medical history and BMI: Pre-existing conditions like diabetes, hypertension, or a cardiac history, and a BMI outside the healthy range, commonly trigger either a premium loading or a requirement for additional medical tests before the policy is issued.
- Occupation and lifestyle: Hazardous occupations (mining, offshore work, aviation) and high-risk hobbies (scuba diving, motor racing, mountaineering) can increase premiums or require specific declarations and exclusions.
- Sum assured and policy term: Larger cover and longer terms raise the absolute premium, though the rate charged per lakh of cover often improves at higher sum-assured bands.
- Payout structure: A flat lump sum is the cheapest structure. Increasing cover (rising each year to keep pace with inflation) and monthly-income payout variants cost more for the same starting cover. Return of Premium plans cost substantially more still — enough that it’s worth its own section below.
- The insurer itself: Two insurers quoting the same applicant, same cover, same term can still differ meaningfully, because each prices risk against its own claims experience and reinsurance arrangements — which is exactly why comparing quotes across insurers before buying is worth the twenty extra minutes.
Riders: Which Ones Earn Their Keep
A rider is an optional add-on to your base term policy, priced separately. Some are genuinely useful; one in particular is oversold far more than its maths supports.
- Accidental Death Benefit — low cost, pays extra if death is accidental
- Waiver of Premium — keeps the policy alive if you’re diagnosed with a serious illness or disability and can’t pay
- Critical Illness rider — pays out on diagnosis, independent of hospitalisation, complementing rather than replacing health insurance
- Return of Premium (ROP) — refunds all premiums paid if you survive the term, but typically costs 2–3× a pure term premium for that promise
- The maths rarely works in the buyer’s favour: investing the difference between a pure term premium and an ROP premium, even conservatively, tends to outgrow the eventual “refund” — the same core argument as term-plus-mutual-funds beating a ULIP
Claim Settlement Ratio, Read Correctly
The claim settlement ratio (CSR) — the share of claims an insurer actually pays out of those it receives in a year — is the single most repeated piece of advice in term insurance shopping, and it deserves to be read with a bit more care than “pick the highest number.”
- IRDAI publishes claim settlement data annually in its Annual Report, available directly at irdai.gov.in — that’s the authoritative source, not a comparison website’s summary of it
- Industry-wide, the individual death claim settlement ratio has stayed in the high-90s percentage range for several consecutive years, though the exact figure shifts a little each year and varies noticeably between individual insurers
- Look at CSR “by amount,” not just “by number of claims,” if you’re buying a large sum assured — a high ratio on small claims can mask slower or tougher scrutiny on large payouts
- Prefer an insurer’s multi-year trend over a single year’s snapshot, and treat a small insurer’s very high ratio on a small number of claims with some caution — the sample size matters
- A slightly higher premium at an insurer with a strong, consistent CSR is usually a trivial cost next to the size of the payout your family is counting on
Quick Reference: Premium Factors at a Glance
