what the same money buys, in today’s terms

Almost every savings target in India is set in today’s rupees and reached in tomorrow’s. This page shows exactly how much of the target inflation takes back, and what the number should have been.

Why ₹1 Crore Stopped Being a Milestone

A crore has been the standard Indian financial milestone for a generation, and that is exactly the problem: the number has stayed the same while the price of everything it was meant to buy has not. A target fixed in nominal rupees is silently revised downwards every year by an amount nobody puts on a statement.

The arithmetic is unforgiving and completely mechanical. At 6 percent inflation prices roughly double every twelve years. Over twenty years, ₹1 crore buys what about ₹31 lakh buys today. Over thirty years it buys about ₹17 lakh worth. Nothing has been lost or stolen; the unit of measurement simply changed while the number did not.

This matters most for the two targets people set furthest out, retirement and children’s education, because those are precisely the ones where the horizon is long enough for the effect to dominate. The model below reports three separate numbers that are routinely confused: what the money will buy, what you would need then to match today, and what happens if the money is invested rather than held.

Three Numbers People Confuse

The purchasing power then answers what the money buys. It is the figure to use when someone says a crore will be enough, because it converts that crore into goods and services at today’s prices, which is the only way a human being can judge whether an amount is sufficient.

The amount needed then is the same calculation inverted, and it is the number that should replace your target. If you want the buying power of ₹1 crore in twenty years, the goal is not ₹1 crore. Setting the goal correctly at the outset is far easier than discovering the shortfall a year before you need the money.

The real value of the investment is where the two meet. A nominal return of 11 percent against 6 percent inflation is not a 5 percent real return, it is about 4.72 percent, because the adjustment is a ratio rather than a subtraction. Over twenty years that apparently small distinction compounds into a meaningful difference, and it is why real returns should always be computed rather than estimated in the head.

What Changes the Answer

Your personal inflation rate is not the CPI

The Consumer Price Index is a basket weighted for the average household. If a large share of your spending is school fees, health cover or domestic help, your lived inflation runs well above the headline number. Plan on the inflation you actually experience, which for most urban professional households is above the published figure.

Which asset the money sits in

Cash in a savings account at 3 percent is losing about 3 percent of its purchasing power a year at 6 percent inflation. A fixed deposit taxed at slab rates often ends up roughly flat in real terms. Only assets with a real return above zero preserve value, and the difference between preserving and eroding is not the headline rate but the rate net of both tax and inflation.

Tax, which applies to the nominal gain

This is the quiet penalty of inflation. Tax is charged on the whole nominal gain, including the part that merely compensates for inflation, so the real post-tax return is lower than a simple subtraction suggests. The higher the inflation, the larger the share of the tax bill that is levied on an illusory gain.

The horizon, which compounds the effect

Erosion is not linear. Over ten years at 6 percent inflation a rupee keeps about 56 paise of its buying power; over twenty years about 31 paise; over thirty about 17. Each additional decade takes a larger absolute bite than the one before, which is why long-dated targets need the largest correction.

How We Calculated This

Inflation compounded annually at the constant rate you enter
Purchasing power is the amount divided by the inflation factor
Investment return compounded annually, before tax
Real value uses the ratio method, not return minus inflation
No tax on the nominal gain is deducted
No further contributions, only the single amount entered

The Decision Framework

1
Set every long-dated target in real terms first
Decide what standard of living or what expense you are funding, price it today, and only then inflate it to the year you will need it. A target chosen because it is a round number is a target chosen at random.
2
Use your own inflation rate, not the headline one
Look at what your household actually spends on and how those specific prices have moved over five years. For most urban professional households the honest figure sits above the published CPI.
3
Judge every asset on its real post-tax return
The question is never what an instrument pays. It is what it pays after tax, minus inflation. An 7 percent deposit taxed at 30 percent against 6 percent inflation is losing purchasing power slowly while looking entirely safe.
4
Revisit the target, not just the portfolio
People review their funds every year and their goal almost never. If the target was set in nominal rupees five years ago, it has already been quietly devalued and needs restating before the portfolio review means anything.

Frequently Asked Questions

What inflation rate should I plan with?+
India’s headline CPI has generally run in the 4 to 7 percent range over the last decade, and the Reserve Bank targets 4 percent with a tolerance band on either side. For household planning, 6 percent is a reasonable general assumption, but education and healthcare have consistently run several points above that, so goals dominated by those two deserve a higher figure.
Is a fixed deposit a safe place for long-term money?+
It is safe in nominal terms and frequently unsafe in real terms. A deposit paying 7 percent, taxed at a 30 percent slab, returns about 4.9 percent after tax. Against 6 percent inflation that is a real loss of roughly 1 percent a year, every year, with complete certainty. Safety of capital and preservation of purchasing power are different properties.
Why is the real return not simply return minus inflation?+
Because the adjustment is a ratio, not a difference. The correct calculation is one plus the return divided by one plus inflation, minus one. At 11 percent against 6 percent that gives 4.72 percent rather than 5. The gap is small in one year and material over twenty, which is why it should be computed rather than approximated.
Does gold protect against inflation?+
Over very long periods gold has broadly held purchasing power, which is a different claim from beating inflation. It produces no income, so the entire return depends on price movement, and there have been long stretches of a decade or more where it lost real value. It works better as a diversifier alongside other assets than as a primary inflation hedge.
Should I increase my SIP every year for inflation?+
Yes, if the goal is set in real terms. A fixed SIP contributes a shrinking share of your income each year as your salary rises, so the plan quietly loses ground. A step-up of 5 to 10 percent a year roughly tracks both income growth and inflation and usually reaches the target far earlier than a flat contribution.
How does inflation affect a loan?+
In the borrower’s favour, which is the one place it helps. A fixed EMI becomes a smaller share of a rising income each year, so the real burden of a long fixed-rate loan falls over time. This is a genuine argument against aggressively prepaying a cheap long-tenure home loan when the alternative use of the money earns a higher real return.
