How Do I Decide the Right Sum Insured for My Family?

The last thing you want to think about when a loved one is unwell is a calculator. Imagine standing at a hospital billing desk, already exhausted from a long night in the waiting room, only to realise your insurance cover will not even pay for half the treatment.

It is a moment of pure helplessness that no one should face. We often buy health insurance just to check a box, but choosing a random number as your "sum insured" is like carrying a tiny umbrella in a Mumbai monsoon. It might look like protection, but it will not keep you dry when it actually pours.

The Reality of Medical Inflation in 2026

We cannot ignore how fast healthcare costs are climbing. In India, medical inflation has hit a staggering 14% for the 2025-26 cycle. This is nearly three times the rate of general inflation. To put that in perspective, a surgery that cost you ₹1 lakh last year could easily cost ₹1.14 lakh today.

Private hospitals are investing in advanced robotic surgeries and imported diagnostic tools. While these technologies save lives, they also come with a heavy price tag. If your family's coverage has stayed the same for the last three years, its actual value has likely shrunk significantly.

Consider Where You Live

Your location is the biggest factor in deciding your cover. If you live in a metro city like Delhi, Mumbai, or Kolkata, hospital room rents alone can eat up a huge chunk of your sum insured. Experts and financial planners now suggest that for a family of four living in a metro, a cover of ₹10 lakh is often the bare minimum and rarely enough.

For urban households, a safer starting point is now ₹20 lakh to ₹25 lakh. In smaller Tier 2 or Tier 3 cities, you might manage with ₹10 lakh to ₹15 lakh, but even there, costs are rising as specialised care becomes more accessible.

Think About the Largest Possible Bill

When deciding on a number, do not think about a fever or a minor injury. Think about the "big" risks. Modern treatments for critical illnesses like cancer or heart procedures in premium private hospitals can range anywhere from ₹5 lakh to ₹12 lakh for the initial stages alone.

Since a family floater plan shares the total amount among all members, one major hospitalisation can leave the rest of the family unprotected for the remainder of the year. If you have elderly parents included in the plan, the risk of multiple claims in a single year increases.

The Smart Way to Increase Your Cover

You do not always have to pay a massive premium to get high coverage. A very effective strategy is to buy a base plan of ₹5 lakh or ₹10 lakh and add a "Super Top-up" plan of ₹20 lakh or ₹30 lakh. This combination is much cheaper than buying a single ₹40 lakh policy.

It acts as a safety net that kicks in once your base cover is exhausted, ensuring that a single medical emergency does not wipe out your life savings.
