This article explains a general approach for educational purposes. It is not personalised insurance advice, a qualified insurance advisor can help tailor cover to your specific circumstances.
Buying a health policy for a round, familiar sum insured, ₹5 lakh or ₹10 lakh simply because it sounds substantial, feels reasonable, but a calculation based on your specific city, family size, and genuine risk factors gives a considerably more accurate, personally relevant number.
Why Your City Genuinely Matters
Healthcare costs vary meaningfully between cities and even between hospital tiers within the same city, a major surgery or extended ICU stay at a well-regarded private hospital in a larger city can cost considerably more than the same treatment at a facility in a smaller town, worth basing your sum insured on realistic costs at the hospitals you'd actually use, not a generic national average.
Family Size and Age Composition
A family floater's shared sum insured, as discussed in our family floater guide, needs to be adequate not for one member's potential claim, but for the realistic possibility of multiple claims, or one genuinely major claim, within a single policy year across everyone covered, worth sizing this meaningfully higher than you might for an individual policy covering just yourself.
A Practical Starting Benchmark
A commonly discussed starting point for a family in a larger city is a base sum insured somewhere in the range of ₹10-25 lakh, with a top-up extending this further, for a smaller town, this baseline might reasonably be somewhat lower given generally lower treatment costs, though a genuinely serious condition requiring specialised treatment might still require travel to a larger city's facilities, worth keeping this possibility in mind rather than assuming local costs alone define your ceiling.
Why a Base Policy Plus Top-Up Structure Often Makes More Sense Than One Large Base Policy
As discussed in our top-up plan guide, a modest base policy combined with a top-up or super top-up extending your total coverage ceiling is often considerably more cost-efficient than a single, very large base policy, worth structuring your total cover this way rather than assuming you need one large policy to reach your target sum insured.
Factoring In Your Family's Specific Health History
A family with a history of specific conditions, cardiac issues, diabetes, or similar, genuinely faces a higher probability of needing more extensive treatment, worth sizing your cover somewhat more generously if this applies to your specific family history, rather than using a purely generic calculation.
Accounting for Rising Healthcare Costs Over Time
As discussed in our inflation guide, healthcare costs have historically risen faster than general consumer inflation, a sum insured that feels adequate today may not remain so in 10-15 years, worth reviewing and increasing your cover periodically, rather than assuming a figure chosen years ago remains appropriate indefinitely.
Employer Group Cover Should Not Be Your Only Consideration
As discussed in our group health insurance gaps guide, your employer's group policy shouldn't be factored into your long-term cover calculation as a permanent, reliable component, since it ends with your employment, worth calculating your genuinely necessary independent cover as if the group policy didn't exist at all.
A Practical Calculation Framework
- Research realistic costs for a major hospitalisation or surgery at hospitals you'd genuinely use
- Multiply this by a reasonable buffer for a family floater covering multiple people
- Structure this total through a base policy plus a cost-efficient top-up, rather than one large base policy alone
- Review and increase this figure periodically to keep pace with rising healthcare costs

Frequently Asked Questions
Is ₹5 lakh sum insured genuinely enough for a family today?
For a smaller town with modest healthcare costs, this may cover routine hospitalisation reasonably, but is often considered on the lower side for a genuinely major procedure, particularly if treatment at a larger city's facility becomes necessary, worth considering a top-up to extend this baseline.
Should I buy the maximum sum insured I can afford?
Not necessarily, worth balancing adequate cover against your overall budget and other financial priorities, a reasonable base plus top-up structure, as discussed above, often achieves adequate cover more cost-efficiently than the single largest base policy available.
Does sum insured need to be the same for every family member on a floater?
On a floater, the sum insured is shared across all members rather than individually assigned, if you want different, specific cover levels for different members, individual policies, as discussed in our family floater guide, allow this distinction.
How often should I reassess whether my sum insured is still adequate?
Reviewing this at each renewal, alongside your broader annual financial review, as discussed in our annual review habit guide, is a reasonable, practical cadence.
