What the future value is really worth

This page answers a question a plain projection cannot: after inflation, what will that final amount actually buy? Enter the principal, an expected return, an inflation assumption, and the tenure, and you get the nominal value, the same figure restated in today's rupees, and the purchasing power lost between the two.

The gap that matters is the one between the two rates

A 9% return against 6% inflation leaves you roughly 3% a year of real growth — nothing like the headline figure, and the number your goal is actually funded by. Where the two rates are close, a long tenure can produce an impressive nominal corpus that has barely grown in real terms at all, which is the trap that makes low-return instruments look safer than they are over decades.

For recurring contributions, use the SIP inflation calculator. For the nominal projection alone, use the core lumpsum calculator.

FAQ

Lumpsum inflation calculator FAQs

What does this lumpsum inflation calculator show?

It projects your one-time investment at the expected return, then converts the maturity value into today’s purchasing power using your inflation assumption. You also see purchasing power loss and an approximate real return rate.

How is today’s value calculated?

Today’s value = nominal final value ÷ (1 + inflation)^years. That tells you what the future corpus could buy in today’s rupees.

Should I use this instead of the core lumpsum calculator?

Use the core lumpsum calculator for a simple nominal projection. Use this page when you care whether the maturity amount still meets a goal after inflation.
