In 2026, that same sum insured is looking increasingly thin against the actual cost of a serious hospitalisation, and a growing number of financial advisors are urging policyholders to treat their existing cover as a starting point for review rather than a settled decision. Understanding why this shift has happened, and what actually determines whether ₹5-10 lakh is enough for a given household, matters more than simply following a rule of thumb.
The Arithmetic of Medical Inflation
Medical inflation in India has hovered between 10% and 14% annually for several years, consistently outpacing general consumer inflation by a wide margin. Using an illustrative medical trend estimate of around 11.5% for 2026, a treatment that costs ₹10 lakh today could realistically cost meaningfully more within just a handful of years, simply from the compounding effect of rising hospital tariffs, consumables, and procedure costs. At double-digit annual medical inflation, the effective value of a fixed sum insured roughly halves every seven years if the cover is never revised upward. Health Insurance bought a decade ago at ₹5 lakh or ₹10 lakh once felt like more than enough protection for an average Indian family.
This is the core reason a ₹5 lakh or ₹10 lakh policy that felt generous when purchased can quietly become inadequate over time, even though the policyholder has done nothing wrong; the cover simply has not kept pace with what hospitals now charge for the same procedures.
What Actually Drives the Bill Higher Than Expected
Three types of medical events are most likely to expose a shortfall in a ₹5-10 lakh policy: major illnesses, complications during otherwise routine procedures, and treatments requiring advanced or newer medical technology. Serious hospitalisations for conditions like cancer, cardiac bypass surgery, or organ transplants routinely run between ₹20 lakh and ₹30 lakh in private facilities in major cities, figures that comfortably exceed a ₹10 lakh sum insured on their own.
Even procedures generally considered routine are not immune. A gall bladder removal or an orthopaedic surgery might be estimated at ₹2.5-3 lakh, well within a ₹5 lakh policy, but a complication requiring an extended ICU stay can push the same case well past the original estimate, leaving the family to cover the overrun from savings. This is precisely the scenario that tends to catch families off guard: not a catastrophic diagnosis, but an ordinary procedure that develops complications mid-treatment.
Five Factors That Determine the Right Number for Your Family
There is no single sum insured that fits every household, but five factors consistently determine where a family should land. City and hospital choice matter enormously: hospital costs differ sharply between a metro and a smaller town, and someone planning to use large private hospitals in Mumbai, Delhi, Bengaluru, Hyderabad or Chennai needs a materially larger buffer than someone relying on lower-cost hospitals elsewhere. Family composition and ages matter too, since a policy covering ageing parents needs a higher cushion than one covering only young, healthy adults, given how claim frequency and severity both rise with age.
The type of policy structure, individual versus family floater, also affects adequacy. Under a family floater, one member’s major hospitalisation can exhaust the shared sum insured, leaving nothing for other family members for the rest of the policy year, which argues for a higher floater limit than the sum of what each member might individually need. Existing health conditions and lifestyle risk factors shift the calculation further, since a family with a history of cardiac or metabolic conditions should size cover toward the higher end of any range under consideration. Finally, the policy’s own fine print, including room-rent sub-limits, disease-wise capping, and co-payment clauses, can mean that even an apparently adequate sum insured pays out less than expected if the plan carries restrictive terms.
A More Realistic Benchmark for 2026
Where ₹5-10 lakh was once treated as a reasonable default, several advisors now suggest a base sum insured starting around ₹20-25 lakh per individual in a tier-1 or metro city, with a family floater covering parents pushed toward ₹50 lakh or more once medical inflation projections are factored in. These figures are not universal prescriptions, but they reflect how far the “adequate” benchmark has shifted from where it stood even five years ago.
The Base-Plus-Super-Top-Up Approach
For families who find a ₹50 lakh or ₹1 crore base policy premium unaffordable, industry practice increasingly favours combining a moderate base policy with a large super top-up rather than buying one large indemnity policy outright. A commonly cited structure pairs a ₹10 lakh base policy with a ₹90 lakh super top-up, delivering ₹1 crore of effective coverage at a fraction of the premium a single ₹1 crore base policy would cost, since the super top-up layer typically only activates once a deductible threshold, matching the base sum insured, has been exhausted. This approach has become more attractive still following the removal of GST on individual health insurance premiums from September 2025, which has lowered the effective cost of stacking a base policy with a super top-up.
What to Do With an Existing ₹5-10 Lakh Policy
The right response to an ageing, potentially inadequate policy is rarely to cancel it and start over, since doing so can reset waiting periods for pre-existing conditions. Instead, most policyholders are better served by adding a super top-up policy on top of their existing base cover, preserving continuity while substantially raising the effective protection available. Reviewing the sum insured annually at renewal, rather than renewing on autopilot, is the single most effective habit a policyholder can build to make sure Health Insurance keeps pace with what hospitals actually charge, rather than what they charged when the policy was first purchased.
How to Actually Run the Annual Review
A useful, repeatable way to run this annual review is to compare the policy’s current sum insured against two reference points: the average cost of a major hospitalisation for a condition relevant to the family’s health history in their specific city, and the family’s own income growth since the policy was last revised. If either reference point has moved meaningfully while the sum insured has stayed flat, that is a clear signal the cover needs revisiting, whether through a straightforward increase in the base policy’s sum insured at renewal or the addition of a super top-up layer.
It is worth noting that increasing sum insured at renewal, rather than only at the point of switching insurers, generally preserves continuity benefits like waiting-period credit for pre-existing conditions and accumulated no-claim bonus, both of which would otherwise reset if the family moved to an entirely new policy. Insurers are required to allow existing policyholders to enhance their sum insured at renewal critical health insurance, typically subject to fresh underwriting only for the incremental cover amount, which makes the annual review a lower-friction process than many policyholders assume.
A Final Word on Family Floater Sizing
For families specifically using a floater structure, it is worth running a simple stress test: imagine the family’s oldest or highest-risk member experiencing a major hospitalisation early in the policy year, and ask whether the remaining sum insured would still meaningfully protect the rest of the family for the balance of that year. If the answer is no, that floater is undersized regardless of how comfortable the headline number looks on paper, and either a higher floater limit or a combination of individual top-up policies for the highest-risk members deserves serious consideration at the next renewal.
