Insurance: protecting against large losses
Written and reviewed by Prashant Nandkishor Maheshwari (editorial review, 2026-10-18). Not yet checked by an independent subject specialist. How we review.
What you will learn
Describe the main kinds of insurance, estimate a protection gap, and compare policies sensibly.
Why it matters
One large, unexpected cost can undo years of saving. Insurance moves part of that risk to an insurer for a known, smaller price.
The ideas
Levels are a learning preference, not a credential. Switch any time.
Novice level
Insurance is worth considering for losses that would be large, unlikely and hard for you to absorb: serious illness, death of an earner, loss of a home, a vehicle accident.
You pay a regular premium. If the insured event happens, the insurer pays according to the policy.
Read what is covered, what is not (exclusions), and what you pay first (the deductible or excess). The cheapest policy is not always the best one.
Basic level
Term life insurance pays a sum if the insured dies during the term and has no savings value. It is meant for people whose income supports others.
Health insurance covers medical costs up to a limit. Check waiting periods, sub-limits, room-rent caps and claim procedures.
To estimate a life-cover gap, add the money your dependants would need over the years they rely on you, then subtract what they would already have.
Mixing insurance and investing in one product makes both harder to judge. Compare the cost of each part separately.
Advanced level
Compare policies on total expected cost, claim conditions and insurer financial strength, not premium alone. Check portability and renewal terms for health cover.
Expert level
Adverse selection and moral hazard shape pricing and exclusions. Self-insuring small risks and insuring large ones is usually cheaper over time.
Professional level
Advice on insurance products is a regulated activity in many places. Disclosure of material facts when applying is a legal duty: omissions can void a claim.
Key terms
- Premium
- The price paid for cover.
- Sum insured
- The most the insurer will pay.
- Exclusion
- Something the policy does not cover.
- Deductible / excess
- The part of a loss you pay first.
Worked example
Illustration only. Dependants need ₹6,00,000 a year for 15 more years: ₹90,00,000. They already have savings and other assets of ₹20,00,000. The protection gap is ₹70,00,000. This is a way to frame a question for an adviser, not a recommendation of any amount.
Try it yourself
List who depends on your income and for how long. Estimate what they would need and what they already have. Write the gap, and one question about each exclusion you find in your current policies.
Nothing you write here is collected. Use paper or the workbook.
Check yourself
A common misunderstanding
'More cover is always better.' Cover beyond what you need costs more every year. Aim for the gap you actually have.
Local context
Products, taxes on premiums and claims, and consumer protections vary. Check your insurance regulator (in India, IRDAI) before buying, and compare insurers' published claim-settlement figures.
