How much health insurance does a family actually need?

Health insurance is the cover that decides whether a medical emergency is a stressful few weeks or a financial catastrophe that wipes out a decade of saving. And yet the typical Indian family buys a ₹5 lakh floater, often the cheapest one the agent offered, and assumes it is enough. It is not, and the reason is simple: medical costs in private hospitals have been rising at roughly 14 percent a year, far faster than general inflation. A bill that was ₹4 lakh five years ago is ₹8 lakh today.

The good news is that high cover is far cheaper than people assume, if you buy it in the right structure. You do not pay for ₹25 lakh of cover the way you pay for ₹5 lakh, five times over. You pay a small base premium plus a tiny top-up premium, and the maths works heavily in your favour.

Why ₹5 lakh is the dangerous default

A single stay in a private ICU in a metro, for something as ordinary as a bad infection or an accident, can run ₹3 to 6 lakh in a week. A heart procedure, a cancer treatment cycle, or a major surgery can cross ₹10 to 15 lakh easily. On a ₹5 lakh family floater shared across three or four people, one such event empties the cover, and if a second person needs treatment the same year, you are paying out of pocket. The cover that felt adequate when you bought it is set by today's prices, but you will claim on it at tomorrow's.

The cheap way to high cover: base plus super top-up

A 'super top-up' is a policy that only pays once your total medical bills in a year cross a chosen threshold, called the deductible. Because it sits above your base policy, it is dramatically cheaper than buying the same cover as a base plan. You use your base policy for ordinary claims and the super top-up only kicks in for the big, rare, ruinous bills, which is exactly where you need the protection.

Buying ₹25 lakh as a single base policy might cost ₹45,000 to ₹60,000 a year. The base-plus-top-up structure gets you the same ₹25 lakh ceiling for roughly half that. The premiums above are indicative and vary with city, ages and insurer, but the principle holds everywhere: top-up cover is cheap because it rarely pays, and that is fine, because you are insuring against the rare disaster, not the routine bill.

What to check before you buy, beyond the cover amount

• Room-rent capping. If the policy limits your room to '1 percent of sum insured per day', a costlier room proportionally reduces your entire claim. Prefer policies with no room-rent capping.
• Co-payment. A co-pay means you pay a fixed percentage of every claim yourself. Avoid co-pay policies if you can, especially for younger families.
• Pre-existing disease waiting period. Existing conditions are usually only covered after two to four years. Buy early, while you are healthy, so the waiting period is behind you before you need it.
• No-claim bonus. Good policies increase your cover (or reduce your premium) for every claim-free year, sometimes up to double the sum insured. This is free extra cover for staying healthy.
• Network hospitals. Check that hospitals you would actually use are on the insurer's cashless network in your city.
