1. Why your cover number matters
A single hospitalisation for a serious illness can cost ₹5L–₹20L in a metro hospital. Cancer treatment, cardiac surgery, and organ transplants routinely exceed ₹10L. If your cover is only ₹3L–₹5L (the typical employer plan), you're exposed to the difference — which could wipe out your savings.
Most financial advisors now recommend a base health cover of at least ₹10L–₹25L per family, plus a super top-up for extra protection.
2. The starting point: base cover per person
A rough starting point is ₹5L–₹10L per person, adjusted by age and city:
| Age | Base cover per person |
|---|---|
| Under 35 | ₹5L – ₹10L |
| 35–45 | ₹10L – ₹15L |
| 45–55 | ₹15L – ₹20L |
| 55–65 | ₹20L – ₹30L |
| 65+ | ₹30L+ |
These numbers reflect the rising cost of treatment as you age — and the higher likelihood of needing it.
3. Medical inflation — the invisible factor
Medical costs in India rise by 10%–14% per year — higher than general inflation. A procedure that costs ₹5L today will cost ₹9L–₹10L in just 7 years.
This means the cover you buy today will feel smaller every year. Two implications:
- Buy more cover than you think you need, because inflation will erode it.
- Choose policies with no-claim bonuses that increase your sum insured each year.
Rule of thumb: If you're buying ₹10L today and medical inflation is 12%, that cover will feel like ₹5.5L in 5 years and ₹3L in 10 years — unless your sum insured keeps growing.
4. City tier makes a big difference
Treatment costs vary enormously by location. A cardiac bypass that costs ₹6L in a tier-2 city might cost ₹9L in a metro. Use this rough index:
| City tier | Cost index |
|---|---|
| Metro (Mumbai, Delhi, Bangalore, Chennai) | 1.35× |
| Tier 1 (Pune, Hyderabad, Ahmedabad) | 1.15× |
| Tier 2 (Jaipur, Kochi, Indore) | 1.00× |
| Tier 3 (smaller cities & towns) | 0.85× |
If you live in a metro, add 30%–40% to your cover. If you're in a tier-3 city, you can get away with slightly less — but consider that serious illnesses often require treatment in a metro hospital anyway.
5. Family size and per-person vs. floater
A family of 4 faces roughly 2–3× the hospitalisation risk of a single person. So your family cover should be substantially higher than a single-person cover.
A practical approach:
- Single person: ₹10L–₹15L cover.
- Couple: ₹15L–₹20L cover.
- Family with 2 children: ₹20L–₹25L cover.
- Family + dependent parents: ₹25L–₹40L cover.
A family floater shares one sum insured across all members. This is usually more cost-efficient than separate policies, but be careful — if one member has a large claim, the cover is used up.
6. Health and lifestyle factors
These push your cover need higher:
- Pre-existing conditions: Higher chance of complications and repeat hospitalisation. Add 20%–30%.
- Family history of critical illness: Genetic risk factors (heart disease, cancer, diabetes) suggest higher cover. Add 15%–25%.
- High-risk lifestyle: Smoking, heavy drinking, or high-stress work. Add 10%–20%.
None of these factors mean you can't get insurance — they simply mean you should prioritise having more cover, not less.
7. Don't forget the super top-up
A super top-up is one of the most cost-efficient ways to boost your cover. You buy a base policy (say ₹5L) and a super top-up of ₹20L with a deductible of ₹5L. When a claim exceeds ₹5L, the top-up pays the rest.
Example: ₹25L effective cover for often less than the cost of a ₹10L base policy. This is why most financial advisors recommend a base + super top-up structure over a single large policy.
✓ Base policy (₹5L–₹10L) + super top-up (₹15L–₹25L) is the most cost-efficient structure for most families.
8. A worked example
Take a 35-year-old living in Bangalore (metro), with a spouse (32) and one child (5). No pre-existing conditions, no family history, non-smokers.
| Step | Calculation |
|---|---|
| Base cover per person | ₹10L |
| Family factor (3 members) | × 1.8 |
| City factor (metro) | × 1.35 |
| Health factor | × 1.0 |
| Recommended cover | ₹24.3L → round to ₹25L |
With an employer cover of ₹5L, the gap is ₹20L. The recommendation would be:
- Personal base policy: ₹10L
- Super top-up: ₹15L (with ₹10L deductible)
- Total effective cover: ₹25L
This structure often costs ₹20,000–₹25,000/year — far less than a single ₹25L policy.
9. Review your cover regularly
Your cover need changes over time. Re-evaluate:
- Every 2–3 years.
- When you add a family member (marriage, child).
- When you move cities.
- When a family member develops a health condition.
- When medical costs in your city rise significantly.
The worst outcome is to discover, mid-emergency, that your cover isn't enough. Regular reviews prevent that.
10. Final thoughts
Health cover isn't about hitting a specific number — it's about matching your cover to your real risk. Age, city, family size, health history, and medical inflation all push the number up or down.
Use this calculator to get a realistic estimate. Then compare quotes from 3–4 insurers, and consider a base policy + super top-up structure. The goal is simple: never be in a position where a medical emergency forces you to choose between treatment and financial ruin.
