How much health insurance cover do you actually need?
A practical way to size your sum insured — by city, family stage and the cost of the treatments you would actually claim for.
Key takeaways
- Size cover against the real cost of hospitalisation in your city, not a round number.
- A metro family of four generally needs materially more base cover than a single person in a smaller town.
- A super top-up is the cheapest way to add a large cushion once you have a sensible base.
Most people pick a health cover figure because it sounds "enough" — ₹5 lakh, ₹10 lakh — without checking it against what a real hospital bill looks like. The right way round is to start from the treatment, then work back to the cover.
Start from the cost of a real claim
The single biggest driver of sum insured is where you live and where you would be treated. A planned surgery in a top private hospital in a metro can cost several times the same procedure in a tier-2 town. If your natural hospital is a large corporate chain, your cover has to match that price list — not the cheapest option available.
Ask three questions:
- Which hospital would you actually go to for something serious?
- What does a major procedure there — a cardiac stent, a joint replacement, a cancer treatment cycle — broadly cost today?
- Would a single such event wipe out your cover for the rest of the year?
Match cover to your family stage
Cover is not one-size-fits-all across life stages:
- Single, early career: a solid individual base plan is usually enough to start, with the intent to raise it later.
- Young family: a floater covering both partners and children spreads cost, but remember a floater is shared — one large claim can exhaust the whole family's cover for the year.
- Ageing parents: older members claim more often and cost more to insure. A separate policy for parents usually works better than stretching one floater across two generations.
The smart structure: base + super top-up
You rarely need to buy one giant plan. A common, cost-efficient structure is a base plan for everyday and mid-size claims, topped by a super top-up that only pays once annual claims cross a threshold (the "deductible"). Because the top-up sits above that threshold, it is dramatically cheaper per rupee of cover than buying the same amount as base.
Illustrative example (not a quote): a family might hold a ₹10 lakh base plan and add a ₹40 lakh super top-up with a ₹10 lakh deductible. The base handles routine claims; the top-up is there for the rare, very large event — at a fraction of what a straight ₹50 lakh base would cost.
What "enough" looks like
There is no single correct number, but a useful test is: would your cover comfortably absorb the most expensive realistic event without you having to arrange money? If the honest answer is no, you are under-insured, however large the figure looks.
A Trustner broker can map your city, hospital preference and family to a base-plus-top-up structure and show you real quotes side by side — including room-rent and co-pay terms, which quietly decide how much of a bill you actually get back.
