What insurance is for and is not

Seven chapters on the financial product most people own, understand least, and buy for the wrong reason.

The one job

Insurance transfers a risk you cannot absorb to a party that can.

You pay a small, certain amount so that an uncertain, large loss does not fall on you. The insurer takes on thousands of such risks, and because they do not all occur at once, what is catastrophic to one household is predictable in aggregate.

That is the whole mechanism, and everything useful about insurance follows from it.

You are expected to lose money on insurance. The premiums collected must exceed the claims paid plus expenses, or the insurer fails. A policy with a positive expected return would not be insurance — it would be a transfer from the insurer to policyholders, which no company can sustain.

So the right question is never "will I get my money back?" It is "can I survive this loss without it?"

The test

Insure a risk when both of these hold:

The loss would be financially severe — it would force you to sell assets, borrow at bad rates, abandon a goal, or change your family's circumstances.

You cannot comfortably absorb it from savings.

And do not insure when the loss is small enough to pay from an emergency fund, however likely it is. Likelihood is not the criterion; survivability is.

This inverts how most insurance is sold. Extended warranties, phone protection and gadget cover are sold on how often something breaks. Even if the probability is high, the loss is affordable — so you are paying an insurer's expenses and profit margin to handle something you could handle yourself.

A high-probability, low-severity risk is not an insurance problem. It is a budgeting problem.

What the products do

Product	The risk it transfers
Term life	Your income stops because you die, and dependants lose it
Health	A medical event costs more than you have
Personal accident / disability	You survive but cannot earn
Motor third-party	You injure someone and owe more than you have
Home	The structure is destroyed

Notice what unites them: each is a loss large enough to change a household's financial life. That is the category, and it is a short list.

Why bundling weakens both jobs

A large part of what is sold in India as insurance also invests your money — endowment plans, money-back policies, unit-linked plans. Chapters 3 and 4 take them apart in detail. The structural objection belongs here.

The two jobs want opposite things.

Protection wants the largest possible cover for the smallest possible premium. That argues for term cover, where almost the whole premium buys risk transfer.

Investment wants the lowest possible cost and the freest possible choice of assets, with the ability to stop, switch or withdraw.

Bundling them means the protection is small relative to the premium, and the investment is locked, opaque and expensive. You get less cover than you need and worse returns than you could get, and the single product makes it hard to see either.

The one honest argument for the bundle is behavioural: a policy you cannot easily stop forces you to keep saving, which the Designing around yourself chapter in Behavioural finance treats seriously. That is a real benefit. It is also a very expensive way to buy discipline, and chapter 6 shows how to price it.

The protection you have for thirty days

Worth knowing before any of the chapters that follow. IRDAI's circulars give a policyholder a period of thirty days from the date of receipt of the policy document to review the terms and conditions, and "if he/she is not satisfied with any of the terms and conditions, he/she has the option to cancel his/her policy."

For health policies this applies to policies with a term of one year or more; the life circular carries the same thirty-day period.

That window exists because these contracts are long, complex and sold by people paid on commission. It is the single most under-used consumer right in Indian finance: thirty days to read what you actually signed, with an exit if it is not what you were told. Chapters 3 and 4 give you what to look for inside it.

Working the problem

Ranking: ₹1,500 phone screen, ₹4 lakh hospital stay, death of the only earner, ₹60,000 laptop.

1. Death of the only earner — insure, first and largest. A family of four loses its entire income permanently. No savings most households hold could replace decades of earnings. Maximum severity, total inability to absorb. This is the clearest insurance case there is.

2. ₹4 lakh hospital stay — insure. Severe for almost any household, and medical costs are not optional or deferrable. For most families ₹4 lakh is several years of savings, and the real risk is worse: a serious illness can cost multiples of that.

3. ₹60,000 laptop — probably not. Significant but survivable for most households with an emergency fund. Self-insure, which means owning the risk deliberately rather than by accident.

4. ₹1,500 phone screen — definitely not. Trivially absorbable. Paying a premium to transfer it is paying someone else's costs to handle something you can handle.

The rule: insure by severity relative to what you can absorb, not by likelihood.

The ordering is the inverse of how often these occur. Screens break constantly and earners rarely die — and the rare event is the one to insure, precisely because its rarity is what makes the cover affordable while its severity is what makes it necessary.

A useful cross-check: if the loss happened tomorrow, would you pay it from savings with irritation, or would it change your life? Irritation is self-insurable. Change is not.

The point

Insurance transfers a loss you cannot absorb to a party that can, and because premiums must exceed claims and expenses, you should expect to lose money on it — which makes "will I get my money back" the wrong question and "could I survive this without it" the right one. Insure by severity relative to what you can absorb rather than by likelihood, which is why a rarely-dying earner is the first thing to cover and a frequently-breaking phone screen is not. Products that bundle protection with investment want opposite things from the same premium, and you have thirty days from receiving any policy to read it and cancel.
