Inflation
Money does not lose value at some vague rate. India has a statutory target of 4% with a 2% to 6% band, and planning at one end of that band instead of the other changes what you need by more than most people's investment decisions do.
Chapter 6 · Intermediate
Your grandparents' salary would not cover your rent. Nothing about the money changed — the note in a ₹100 bill from 1990 is still legal tender. What changed is what it buys.
That is the whole of inflation: the same basket of things costs more, so the same money is worth less. It is not a market event, it does not arrive in a crash, and it is the only financial force that operates on you whether or not you invest.
India has an official number
Most people plan against a figure they absorbed somewhere — six per cent, sometimes ten, sometimes whatever last year felt like. There is a statutory one.
Under Section 45ZA of the Reserve Bank of India Act, 1934, the Central Government, in consultation with the RBI, notifies an inflation target in terms of the Consumer Price Index. The RBI's monetary policy overview, read 29 September 2026, states it plainly: 4 per cent CPI inflation as the target, with an upper tolerance limit of 6 per cent and a lower tolerance limit of 2 per cent. The current notification runs from 1 April 2026 to 31 March 2031.
The same page defines what counts as failure, which is worth knowing because it tells you how much drift is tolerated before anyone is obliged to act:
(a) the average inflation is more than the upper tolerance level of the inflation target for any three consecutive quarters; or (b) the average inflation is less than the lower tolerance level for any three consecutive quarters.
Two things follow. Inflation of 5.8% is not a policy failure — it is inside the band. And a whole year at 6.5% is not automatically one either, unless it persists across three consecutive quarters on average.
The band matters more than the target
This is the part that changes plans, and almost nobody does the arithmetic.
If you plan against 4% you are planning against the target. If you plan against 6% you are planning against the edge of what the framework tolerates. Both are defensible. They are not close to each other.
The same thing, priced across the band
A goal, a yearly expense, anything you want the future price of.
- Lower limit — 2%
- ₹1,48,595
- The target — 4%
- ₹2,19,112
- Upper limit — 6%
- ₹3,20,714
Planning at the top of the band instead of the bottom means needing 2.16× as much — ₹1,72,119 more on this amount. Neither figure is a forecast. The point is that a plan should survive the upper limit rather than assume the target.
Over twenty years, the difference between the two ends of that band is a factor of more than two on what you need. That is a larger effect than switching between most investment choices a reader of this course will consider, and it comes from a single assumption people make casually.
The practical position: plan at the upper end, be pleasantly surprised at the lower. Undershooting inflation means arriving at your goal date with a number that no longer buys the thing. Overshooting means arriving early with more than you needed, which is a problem you can live with.
Your inflation is not the CPI
The CPI measures a national basket, weighted by what the average household spends on. Your household is not that household.
If you rent in a metro, pay school fees, and use private healthcare, your personal rate is almost certainly above the headline — those three have tended to rise faster than the basket. If you own your home outright and your spending is mostly food and fuel, yours may be below it.
This is not a criticism of the index. CPI is the right instrument for setting monetary policy for a country. It is simply the wrong instrument for planning your costs, and the mistake is assuming the two are the same number.
The fix is not complicated: take the spending categories from chapter 2, think about which of them have risen fastest in your own experience, and weight accordingly. If housing is 35% of your spending and rents in your city have been rising at 8%, the headline number is not describing you.
What inflation does to the things you own
It is not uniform, and this is where the chapter connects to everything after it.
Cash loses, reliably. Money in a savings account at 3% while prices rise at 6% is losing 3% of its purchasing power a year. It is the only asset that loses by design — chapter 7 puts the number on it.
Deposits and bonds lose more quietly. A fixed rate is fixed. If it was set when inflation was 4% and inflation goes to 6%, the real return falls without anything visible happening on the statement.
Equity has historically kept up better, over long periods, without any guarantee. Businesses can raise prices; a bond cannot reprice its coupon. That is the mechanism, not a promise — and no part of this course will tell you equity is safe because of it.
Debt is the one thing inflation helps. A fixed-rate loan is repaid in money that is worth less each year, which is why a home loan taken at a fixed rate in a high-inflation decade felt cheaper by the end of it.
Why it is invisible
Inflation is not felt as inflation. It is felt as "things are expensive now", and attributed to the shop, the landlord or the government rather than to the arithmetic.
The reason is that it compounds quietly. At 6%, prices double in about twelve years — but nobody experiences a doubling; they experience a hundred small increases, each of which is annoying and none of which is alarming. That is precisely why a plan built on today's prices and no inflation assumption at all fails so completely: the mechanism is invisible until the total is large.
The point
4% is the target, 2% to 6% is the band, and the band is what your plan should respect. Then adjust for your own basket, because the national number was never about you.

Now do it with your own numbers
Take one goal you actually have and a year you want it by. Work out what it costs in today's money, then what the same thing costs at 4% and again at 6%. The gap between those two is what planning at the wrong end of the band would cost you.
