How much health insurance cover do you actually need in India

Your father is admitted for a bypass. You hand over the health card, the hospital sends its estimate, and the approval comes back for less than the bill. Your cover is ₹5 lakh. On the morning of discharge, the difference comes out of your savings. Nothing went wrong with the claim. The policy was just too small.

"How much cover do I need" is the question people answer in the fastest ten seconds of the whole purchase, and regret for years. Most pick a number because it was pre-selected on a comparison screen, or because it sounded like a lot in the year they bought it. Here is how to arrive at a number you can actually defend.

What your sum insured really is

Your sum insured is not a savings goal you are working towards. It is a ceiling on what your insurer will pay in one policy year. Cross it, and the rest is yours.

So the right ceiling depends on one question: what would a serious hospitalisation cost at the hospitals you would genuinely use? Not the cheapest name on the network list. The one you would drive to at 2am. The same procedure at a large metro private hospital and at a smaller hospital in a tier-3 town are not the same bill.

There is a quieter problem too. Healthcare costs in India have typically risen faster than general inflation and faster than most salaries. A sum insured you set once and never revisit gets smaller every year in real terms, without a single word of the policy changing.

The four inputs that decide your number

Where you would be treated. Metro private hospitals cost more, and their room categories cost more, which matters if your plan caps room rent.

Who is on the policy. A floater covering four people can be drained by one bad year. Two claims in the same year share the same pot unless your plan restores it.

Age and family history. Cardiac, cancer and orthopaedic treatment tend to sit at the expensive end. If those run in your family, plan for that end.

What you could absorb yourself. Cover is for the bill that would break you, not the one you could pay from savings without flinching.

Three ways to reach a bigger number

You do not have to buy the whole ceiling as one policy:

Route	How it typically works	What to watch
Raise the base sum insured	Cover from the first rupee, one policy, one premium	Cost per lakh rises steeply as you age, so large base cover gets expensive
Add a super top-up	Pays above a deductible, counting your total bills across the policy year	You must meet the deductible first, from base cover or your own pocket
Restoration or refill benefit	Reinstates the sum insured after it is exhausted	Terms vary widely: some plans restore only for a different illness
Employer group cover	Funded by your employer, often for your family too	Ends with the job, and commonly carries co-pays or room caps

For most people, a moderate base policy plus a super top-up buys a higher ceiling than the same total bought as one large base plan. Check your own quotes, since pricing varies by insurer and age.

The caps that shrink the cover you thought you had

A large sum insured is a headline. What you collect is decided by the clauses underneath it:

• Room-rent limit. Many plans cap the daily room charge, commonly as a percentage of sum insured. Pick a costlier room and, on plans that work this way, other linked charges can be scaled down with it. A ₹10 lakh policy on a tight room cap can pay less than a ₹5 lakh policy without one.
• Co-pay. A fixed share of every claim stays yours, whatever your sum insured is.
• Disease-wise sub-limits. Separate caps on specific procedures, such as cataract or joint replacement. Your sum insured is irrelevant once a sub-limit bites.
• Waiting periods. Pre-existing conditions are covered only after a waiting period, which IRDAI has capped at three years. Buying more cover does not shorten that clock.

This is why "how much" and "what kind" are the same question. Buying a bigger number while ignoring the caps is how people end up with an impressive policy and a disappointing cheque.

How to size your health cover in 20 minutes

1. Pick the two hospitals you would actually use. Not the cheapest in the network. The realistic ones.
2. Ask their billing desk for package rates on two or three common procedures, say an angioplasty or a knee replacement. Real local numbers beat any rule of thumb.
3. Compare that against your current sum insured, remembering the whole family shares it on a floater.
4. Price both routes. Quote a higher base cover, and your existing base plus a super top-up. Compare the ceiling per rupee of premium.
5. Read the caps before you buy. Room rent, co-pay, sub-limits and restoration terms decide what the number is worth.
6. Diarise a review every two to three years, and after any life event.

Step 5 is the one people skip, and it is the one that costs. Rather than compare wordings line by line, FinDecode reads your policy against IRDAI rules and flags your sum insured, room-rent cap, co-pay, sub-limits and waiting periods, every figure taken from your own document.

FAQ

Is ₹5 lakh health cover enough for a family? In a metro, a single serious hospitalisation can approach or exceed that, so ₹5 lakh often works as a floor rather than a comfortable ceiling. The honest answer depends on the hospitals near you. Ask two of them for package rates on a common surgery and compare.

Should I raise my base cover or buy a super top-up? Raising base cover pays from the first rupee but costs more per lakh. A super top-up typically pays above a deductible, so it adds a large ceiling cheaply. Many people use a moderate base plus a super top-up.

My employer already covers me. Do I still need my own policy? Usually yes. Group cover typically ends when the job does, may carry co-pays or room-rent caps, and will not follow you into a gap between jobs or into retirement. A personal policy also keeps your waiting periods ticking on your own terms.

How often should I revisit my sum insured? Every two to three years, and after any life event: marriage, a child, a move to a costlier city, or a new diagnosis in the family. Cover set once and forgotten is the most common way people end up underinsured.

Does a bigger sum insured mean a bigger payout? Only up to the caps. Room-rent limits, co-pay and disease-wise sub-limits can cut a claim well below your sum insured, so read those clauses before buying on the headline number alone.

FinDecode provides AI-assisted analysis to help you understand your policy. It is not legal or financial advice. The structure of sum insured, room-rent limits, co-payment, sub-limits, restoration benefits and the maximum three-year waiting period for pre-existing diseases are set out in IRDAI's health insurance regulations and master circular on health insurance products, published on irdai.gov.in. Treatment costs, premiums and caps vary by hospital, insurer and plan, so confirm the figures in your own policy wording.
