Health Insurance Sum Insured Calculator
How much health cover you should hold today, projecting a major-treatment cost forward at medical inflation.
Formula
Health-care costs rise far faster than general inflation — often 10–14% a year in India — so a cover that looks generous today can be inadequate within a decade. This tool projects the cost of a serious hospitalisation forward at medical inflation and scales it for family size to suggest a sum insured, then subtracts what you already hold to show the gap. Practical tips: a family floater is usually more efficient than individual policies for a young family; a high base cover topped with a super top-up (which kicks in above a deductible) buys large protection cheaply; and check sub-limits, room-rent caps and waiting periods, because a big sum insured riddled with caps protects you less than the headline suggests.
Educational estimate, not insurance advice. Actual needs depend on city, ailment and policy terms. Not financial advice — for informational and analytical use only. Verify all figures with a qualified professional before acting on them.
