Future cost

Explain my result

₹1 crore of spending today would cost about ₹2.4 crore after 15 years if inflation averaged 6.0%. The rate is a scenario, not a forecast.

Compare scenario

What this means

Nominal wealth can rise while purchasing power falls. Compare the investment's after-fee, after-tax return with the inflation relevant to the actual goal.

A future ₹1 crore is not equivalent to ₹1 crore today. Time and inflation change how much the money can buy.

Calculation method

How this tool works

Future cost = present cost × (1 + inflation)^years. Present purchasing power = future amount ÷ (1 + inflation)^years.

The calculator uses one constant annual inflation assumption. It does not forecast CPI or the inflation rate of a specific city, medical treatment, school or property market.

View calculation limitations

Results depend entirely on the values and scenarios entered. The model simplifies real legal, tax, liquidity, valuation and market conditions and should be used to understand relationships—not to predict an actual investment outcome.

Common mistakes

Where a correct calculation can still mislead.

01
Treating a long-term inflation assumption as a forecast.
02
Using headline CPI for a goal with different cost drivers.
03
Comparing nominal investment returns with a real spending target.
04
Ignoring tax and fees when estimating real return.

Questions investors ask

Answers without the sales pitch.

What inflation rate should I enter?

Use a transparent planning assumption related to the goal, then test a higher rate. The tool does not predict future inflation.

Why are there two calculation directions?

One estimates a future price from today's cost; the other discounts a future rupee amount into today's purchasing power.

Is the result specific to Lucknow?

No. It is nationally usable. A local goal can have a different inflation path, so enter an assumption appropriate to that cost.
