What ₹1 crore in 20 years is worth today

A number that shrinks while you chase it

"₹1 crore" is the round number most savings plans are built around. It is also a number with no date on it. A crore in 2046 will not buy what a crore buys in 2026, and how much less it buys depends almost entirely on one assumption: the rate at which prices rise in between.

This post works that out at four inflation rates, 4% to 7%, and then shows what it does to a goal and to the SIP behind it. Every figure is arithmetic on assumed rates, not a forecast.

The calculation

Present value is compounding run backwards. Where compounding multiplies by (1 + r) each year, discounting divides:

Value today = ₹1 crore ÷ (1 + inflation)^20

At 6% inflation, 1.06 to the power of 20 is 3.207, so ₹1 crore in 20 years is worth ₹1 crore ÷ 3.207 = ₹31.2 lakh in today's money. The present value calculator does this division for any amount, rate and term, and the inflation calculator does the same sum from the other side.

₹1 crore at four inflation rates

What ₹1 crore received in the future buys, in today's rupees:

Two things stand out. First, the range is wide: over 20 years, the gap between 4% and 7% inflation is ₹45.6 lakh against ₹25.8 lakh, so the same crore buys 77% more in one world than the other. Second, the gap widens with time. A three-point difference in the rate is a modest change in any single year and a large one after two decades of compounding, which is the magic of compounding working against you.

Which rate to use? RBI targets 4% CPI inflation within a band of 2% to 6%, and retail inflation was 4.82% in August 2026 (see How inflation eats your savings for the latest reading). Headline CPI is an average basket. School fees, hospital bills and city rents have often risen faster, which is why planners use 6% or more for goals like education (Education cost inflation: how to plan a goal 12 years out). Using 4% for a goal whose costs rise at 7% understates the target by ₹1.68 crore over 20 years.

Turn it around: what a goal really needs

The useful version of the question is the reverse. If you want the buying power of ₹1 crore today, how many future rupees do you need in 20 years?

The SIP column uses the same monthly compounding, with each instalment at the start of the month, as the goal calculator and the SIP calculator. The 12% is an assumption for an equity-heavy portfolio, not a promise; at 10%, the flat ₹1 crore needs ₹13,060 a month and the 6% version ₹41,885.

The point is the ratio. Planning for "₹1 crore" at 6% inflation needs about a third of the SIP that planning for "₹1 crore of today's buying power" needs. A plan that hits the nominal target on time can still buy only a third of what it was meant to.

The same goal, measured in time

You can also fix the monthly amount and ask how long the goal takes. That is what the years to goal calculator does: the corpus grows at the assumed return while the target grows at inflation, and the answer is the month the first overtakes the second.

With ₹25,000 a month at an assumed 12%, starting from nothing:

Moving from a flat target to a 6% one adds more than ten years. That is the honest version of How long to build ₹1 crore with a SIP?, which counted nominal rupees. An annual raise in the instalment closes much of the gap; the step-up SIP calculator shows how much.

Two rates, two questions

Present value is often confused with inflation adjustment because the arithmetic is identical. The rate is what changes the meaning.

• Discount at inflation and you get purchasing power: ₹31.2 lakh at 6%, as above.
• Discount at the return you could earn and you get what you would have to invest today, as one lump sum, to have ₹1 crore then: about ₹10.4 lakh at 12% a year, or ₹14.9 lakh at 10%.

Neither is "the" value. The first tells you what the goal is worth; the second tells you what it costs. A helpful shortcut ties them together: the return that matters is the real one, (1.12 ÷ 1.06) − 1, or 5.66% at 12% returns and 6% inflation. Subtracting gives 6%, which looks close and overstates the CAGR you actually gain in buying power.

Rules of thumb

• Write goals in today's money, then inflate them. "₹1 crore of today's money in 20 years" is a plan. "₹1 crore" is a number. Goal-based investing starts here.
• Prices double in about 12 years at 6%. By the rule of 72, 72 ÷ 6 = 12. Two doublings in 24 years means a crore buys a quarter of what it does now.
• Pick the inflation rate for the goal, not the economy. Retirement spending, school fees and a house deposit do not inflate at the same pace.
• Recheck every few years. Inflation over the next 20 years is unknown. The plan should move with what actually happens, not with the number you assumed in 2026.

None of this tells you what inflation will be. It tells you how much the answer depends on it, which is the reason to look. For retirement specifically, how much retirement corpus applies the same discounting to a stream of yearly expenses rather than a single sum.
