How insurance works: pooling, premiums and claims

Insurance is a shared pot of money. Lots of people each pay in a small, fixed amount, and the few who suffer a big loss are paid out of it. You give up a small, certain cost to protect yourself from a large, uncertain one.

Pooling, the core idea. Say 1,000 people each pay 1,000 rupees a year into a pot (an illustration). That’s 10 lakh rupees. In a typical year only one or two of them suffer the loss they’re covered for, so the pot can pay them in full. No single person could easily absorb a 5 lakh rupee shock, but together they can.

The words you’ll meet. The premium is what you pay for the cover. The policyholder is the person who owns the policy. The sum insured is the most the insurer will pay. A claim is your request for payment after a loss.

Sharing the cost of a claim. Many policies make you carry a small part of each loss, which keeps the premium down. A deductible is a fixed amount you pay first: with a 10,000 rupee deductible, a 50,000 rupee claim gets you 40,000. A co-pay is a fixed share you always pay: with 20% co-pay on a 1 lakh rupee hospital bill, you pay 20,000 and the insurer pays 80,000. Both figures are illustrations.

What to insure first. Insure the losses you couldn’t pay for yourself, not the small ones. For most families that order is: term insurance if anyone depends on your income, health insurance for hospital bills, and any cover the law requires, like third-party cover on a vehicle, explained in motor insurance. A broken phone screen you can pay for from savings is rarely worth a premium. When you compare insurers, the claim settlement ratio, the share of claims an insurer paid, is one useful signal, but read it alongside the policy terms.

Did you know? IRDAI’s 2024 Master Circular on policyholder protection says no claim may be rejected or closed just because documents are pending or the claim was intimated late. It also gives you a 30-day free look period on life and health policies to cancel if the terms don’t suit you.

What protects you after you buy. Every policy now comes with a Customer Information Sheet, a short summary of what’s covered and what isn’t. Read it before the free look period ends. If a claim goes wrong and the insurer won’t fix it, the insurance ombudsman is a free next step.

The takeaway. Insurance turns a big, unpredictable loss into a small, predictable cost. Insure what would really hurt, understand how much of each claim you’ll carry yourself, and read the summary sheet before the free look window closes.
