Which way round it works
The usual framing is that things get more expensive. The more useful framing is that a rupee buys less than it used to.
Those sound identical and they lead to different behaviour. If prices are rising, the problem seems to be with sellers, and it feels like something happening out there. If money is losing value, the problem is with the thing you are holding — and holding more of it is not a solution.
The second framing also makes the key consequence obvious. Money kept somewhere it earns less than inflation is not sitting still. It is shrinking, quietly, in the only terms that matter: what it can buy.
Nominal and real
Two numbers describe every return, and only one of them is usually quoted.
| What it measures | Where you see it | |
|---|---|---|
| Nominal return | The growth in rupees | Everywhere — this is the advertised number |
| Real return | The growth in purchasing power, after inflation | Almost nowhere — you compute it |
Roughly, real ≈ nominal − inflation. That approximation is close enough for most thinking, and it produces an uncomfortable arithmetic: an instrument paying 6% when inflation is running at 6% has a real return of approximately zero. You have more rupees and exactly the same purchasing power.
And if the nominal return is 6% while inflation is 7%, the real return is negative — a loss, incurred with complete certainty, in an instrument correctly described as carrying no risk of losing money. Both statements are true at once, and the gap between them is where a great deal of Indian household wealth sits.
What it does over time
Inflation compounds, and that is the part intuition handles badly.
At 6% a year, prices roughly double in about twelve years — the Rule of 72 applied to the thing eroding you rather than the thing growing you. Over a thirty-year retirement horizon, the same rate means the cost of a given basket has multiplied several times over.
This is why a retirement target computed in today's rupees is not a target. Somebody who calculates that they need ₹50,000 a month and stops there has computed today's requirement for a need that begins in twenty years and continues for thirty. The arithmetic of the corpus must be done in future rupees, and the difference is not marginal.
Your inflation is not the published inflation
The headline figure measures a fixed basket for a representative household. You are not that household, and you do not buy that basket.
The consequential point: the categories that inflate fastest are exactly the ones people are saving for. Education and healthcare have historically risen faster than the general index in India, and they are the two largest goals in most household plans. A household with school fees and elderly parents is experiencing an inflation rate materially above the published one.
The practical version of that: when planning for a specific goal, apply an inflation rate appropriate to that category rather than the headline number. Planning education costs at general inflation understates the target, and it does so compounding.
The reverse also holds. Somebody who owns their home outright and has no dependants may be experiencing less than the headline rate. The figure is an average of a population, and no individual lives at the average.
Why this decides where money can sit
Inflation is what makes the horizon question in the order of operations real rather than theoretical.
Short-horizon money. Under a year, inflation barely matters — a few percent over a few months is noise against the certainty of having the amount intact. Safety wins, and accepting a low real return is correct.
Long-horizon money. Over a decade or more, inflation is the dominant risk rather than a footnote. An instrument that cannot fall in nominal terms but earns around the inflation rate delivers, with near-certainty, no growth in purchasing power at all. For a goal twenty years out, that is not caution — it is a different way of failing.
Both sentences are correct simultaneously, and which applies is decided entirely by when the money is needed.
Planning against it
- State every long-term goal in future rupees, not today's. This single correction changes most retirement and education numbers substantially.
- Use a category-appropriate rate for education and healthcare rather than the headline figure.
- Judge every instrument on its real return — subtract inflation before comparing, and be suspicious of any comparison that does not.
- Match horizon to instrument, accepting low real returns on short money and inflation risk on long money as two different problems.
- Recheck periodically. Inflation is not constant, and a plan built on one assumed rate should be revisited rather than trusted for twenty years.
These are the mechanics. What rate to assume, and what to hold, depend on your own circumstances — FNOTrader does not give investment advice.
Seeing real returns rather than nominal ones
The gap between a nominal figure and a real one is arithmetic, and it is worth doing on your own numbers rather than accepting an illustration.
FNOTrader's Mutual Funds app runs contribution schedules against the full AMFI NAV history — around 34 million NAV rows — reporting XIRR and drawdown over any period. Subtracting a reasonable inflation assumption from that figure gives the number that actually describes whether a plan is working.
Common questions
What is inflation in simple terms?
A fall in what money can buy. It is usually described as prices rising, but framing it as the rupee losing value makes the consequence clearer: holding more money is not a defence against it.
What is the difference between nominal and real return?
Nominal return is growth measured in rupees — the number that gets advertised. Real return is growth in purchasing power, roughly the nominal return minus inflation, and it is the one that determines whether you are actually better off.
Can a safe investment still lose money?
In purchasing power, yes and with certainty. An instrument paying 6% while inflation runs at 7% has a real return of about −1%. It cannot lose rupees and it is losing value, and both statements are true at the same time.
Why is my personal inflation rate different from the published figure?
Because the published figure measures a fixed basket for a representative household. Education and healthcare have historically risen faster than the general index in India, so a household with school fees or elderly parents experiences a materially higher rate.
How does inflation affect retirement planning?
It means a target computed in today's rupees is not a target at all. A requirement starting in twenty years and lasting thirty has to be calculated in future rupees, and because inflation compounds, the difference is large rather than marginal.
Does inflation matter for short-term savings?
Very little. Over a few months a few percent is noise against the certainty of having the full amount when needed, so accepting a low real return on short-horizon money is the correct trade.
What inflation rate should I assume when planning?
One appropriate to the category you are planning for rather than the headline number, since education and healthcare have historically inflated faster. Whatever rate is chosen, the assumption should be revisited periodically rather than trusted for two decades.
