Rajesh and Meena bought a ₹10 lakh family floater health insurance policy in 2021.
Their daughter was still in school. Their parents were healthy. Ten lakh felt more than enough.
Five years later, the policy document proudly showed ₹20 lakh. No Claim Bonus had done its job. Rajesh felt relieved.
Then his father needed a heart procedure. The hospital quoted ₹14 lakh. The room rent alone was nearly double what it would have cost in 2021. Medicines, ICU charges, and post-surgery care pushed the final bill higher still.
Suddenly the “₹20 lakh cover” didn’t feel so generous.
That is the quiet reality of medical inflation.
Your Sum Insured does not become smaller. A ₹10 lakh policy remains ₹10 lakh on paper. A ₹20 lakh policy remains ₹20 lakh. What changes is what that money can actually buy. Hospitalisation, surgeries, diagnostics, medicines and post-hospitalisation care keep getting more expensive. The same rupees simply cover less.
What Medical Inflation Really Means
Medical inflation is the steady rise in the cost of healthcare services. It is usually higher than general inflation because of better technology, specialised treatments, rising hospital costs, and the simple fact that more people need care as they age.
It shows up in:
- Higher daily room rents and ICU charges
- Costlier surgeries and implants
- Expensive diagnostics and scans
- Rising medicine and consumable prices
- Longer recovery periods and follow-up expenses
The result is simple: today’s ₹10 lakh is not tomorrow’s ₹10 lakh in real purchasing power.
Nominal Sum Insured is the number printed on your policy.
Real purchasing power is what that number can actually pay for when the hospital bill arrives.
How a ₹10 Lakh Cover Loses Its Strength Over Time
Imagine the same ₹10 lakh policy Rajesh and Meena bought in 2021. If healthcare costs rise at an illustrative 14% every year, the real value of that fixed cover falls steadily.
How a ₹10 lakh health insurance cover loses real value over time at 14% medical inflation
The numbers tell a clear story:
- 2021 → ₹10 lakh
- 2025 → roughly ₹5.92 lakh of today’s purchasing power
- 2030 → roughly ₹3.08 lakh
- 2035 → roughly ₹1.60 lakh
Under this illustrative assumption, a cover that once felt comfortable would buy only about one-third of the care it could have paid for nine years earlier.
These figures are calculated using a constant 14% annual rate for illustration. Actual medical inflation differs by city, hospital, treatment and year. It is not a prediction. It is a way to see how purchasing power can quietly erode.
Does No Claim Bonus Fix the Problem?
Many people, like Rajesh, feel safer once NCB starts adding up.
If you stay claim-free, a typical policy may increase your Sum Insured by 20% each year, often up to a maximum of 100% of the original cover. So a ₹10 lakh policy can grow like this:
₹10 lakh → ₹12 lakh → ₹14 lakh → ₹16 lakh → ₹20 lakh
On paper the protection has doubled. That feels reassuring.
But the real question is different: has the purchasing power of that cover kept pace with rising healthcare costs?
NCB Helps — Until It Can’t
NCB is useful. It is not magic.
How NCB increases your Sum Insured but medical inflation can still reduce its real purchasing power over time
This illustration shows what happens when a ₹10 lakh policy grows to ₹20 lakh through NCB while medical inflation continues at the same illustrative 14% rate.
For the first few years the growing Sum Insured still offers some real gain. Then the NCB reaches its cap. From that point the cover stays at ₹20 lakh while healthcare costs keep climbing.
By 2030 the ₹20 lakh policy has a real purchasing power of roughly ₹6.15 lakh.
By 2035 it is closer to ₹3.19 lakh.
Key point: NCB can help your Sum Insured grow. It does not guarantee that your cover will keep pace with medical inflation forever.
Why NCB Is a Bonus, Not a Complete Strategy
Three practical reasons matter:
1. NCB has limits built into the policy
Most policies define the percentage, the maximum bonus, the overall Sum Insured cap, the conditions for earning it, and what happens after a claim. Not every policy works the same way. Always read the actual terms.
2. Healthcare costs do not stop rising when NCB stops
Once the bonus reaches its maximum, the Sum Insured freezes. Medical costs do not. The gap can widen every year after that.
3. A larger number does not automatically mean enough protection
The useful question is not “How much Sum Insured do I have?”
It is “Will this amount realistically cover the kind of care my family may need when the time comes?”
When Families Should Look at Their Cover Again
There is no single “correct” Sum Insured for every family. The right level depends on family size, age, city, income, existing policies and personal health needs.
It is worth reviewing the cover when:
- The family grows (marriage, children, ageing parents)
- Income rises and lifestyle changes
- The Sum Insured has stayed the same for several years
- NCB has already reached its maximum
- Hospital costs in your city have risen noticeably
- The family’s age or health profile has changed
Rajesh and Meena’s experience is common. The policy was still active. The NCB had worked. Yet the real protection had quietly slipped behind the cost of care.
Practical Ways to Strengthen Cover
Increase the base Sum Insured
Raising the core cover directly improves the foundation of protection (subject to underwriting and premium).
Add a Super Top-Up
A super top-up can sit above a deductible and provide a higher layer of cover when large bills appear. It serves a different purpose from simply increasing the base policy.
Treat NCB as an extra layer, not the whole solution
The healthier approach is usually: solid base cover + whatever NCB you earn + additional protection if needed.
A Simple Way to Check Whether Your Cover Still Fits
Ask yourself these questions once a year:
| Question | Why it matters |
|---|---|
| How many people are covered? | More members mean greater possible exposure |
| Which city do you live in? | Hospital costs vary widely |
| What is the current base Sum Insured? | Your starting point |
| How much NCB has already accumulated? | Shows the extra cover you already have |
| Has the NCB reached its maximum? | Tells you if further automatic growth is possible |
| How long ago was the cover bought? | Older policies may need a fresh look |
| Do you have a super top-up? | Additional protection layer |
| Has the family’s financial situation changed? | Coverage needs often change with income and life stage |
An Annual Health Insurance Check-List
Once a year, look at:
- Current base Sum Insured
- Accumulated NCB
- Maximum NCB allowed under the policy
- Family members currently covered
- Room-rent limits and other sub-limits
- Deductibles and co-payments
- Waiting periods and exclusions
- Whether a super top-up exists or is needed
- Premium relative to the protection
- Whether the total cover still matches the family’s possible needs
The Quiet Truth Most Families Miss
Health insurance rarely fails overnight. It fails gradually.
Medical inflation keeps raising the price of care. A fixed Sum Insured stays the same. NCB can push the number higher for a few years, but it usually stops at a defined limit. After that, the gap can keep widening.
Rajesh and Meena still had a valid policy. The document even showed a higher Sum Insured than they started with. Yet when the hospital bill arrived, the purchasing power of that cover had already fallen behind.
That is why reviewing the policy is not just a renewal formality. It is a chance to check whether the protection you bought years ago can still do the job your family may need tomorrow.
Don’t look only at the number printed on the policy. Look at what that number can realistically pay for when the time comes.
Not sure whether your family’s current health insurance is still adequate?
Take a quiet look at the existing Sum Insured, the NCB already earned, the policy limits, and any additional options available. A short review today can prevent a much larger gap later.
