How to Choose the Right Sum Insured for Health Insurance

Choosing the right sum insured for health insurance is a balance between adequate protection and affordable premiums — getting it wrong in either direction has significant consequences. Under-insuring leaves you exposed to catastrophic out-of-pocket expenses, while over-insuring wastes premium budget. Several key factors should drive your sum insured decision.

City of residence is the primary driver: healthcare costs in Mumbai, Delhi, Bengaluru, and Chennai are 30-50% higher than in tier-2 cities. A heart bypass surgery that costs Rs 2.5 lakh in a small city may cost Rs 6-8 lakh in a premium Mumbai hospital. Minimum recommended sum insured: Rs 10 lakh for individuals in metro cities, Rs 5-7 lakh in tier-2 cities.

For families, add approximately Rs 3-5 lakh per additional member. Age and health profile matter: younger and healthier individuals can start with lower cover and increase over time, while those above 45 or with health conditions should start higher. Medical inflation in India runs at 10-15% annually — a Rs 5 lakh policy today will have the purchasing power of Rs 3 lakh in 5 years at 10% medical inflation.

Build in a buffer or choose plans with annual sum insured enhancement features. Current healthcare costs for reference: routine appendectomy Rs 50,000-1,50,000; heart bypass surgery Rs 3-10 lakh; cancer treatment Rs 5-30 lakh per course; organ transplant Rs 10-50 lakh. If you have employer group insurance, use it as base coverage and buy a personal plan with higher sum insured to supplement it.

Super top-up plans are the most cost-effective way to extend sum insured — a Rs 20 lakh super top-up with Rs 5 lakh deductible costs a fraction of a standalone Rs 20 lakh plan.
