How inflation affects savings
Why a rupee today and a rupee later are not the same, and how to use an inflation calculator honestly.
Publisher: SmartCalculatorsLast updated: 17 August 2026
Two ways to see the same problem
Future required amount is what you would need later to buy what today’s money buys now: P × (1 + i)^t. Purchasing power equivalent is what today’s pile would feel like after t years: P / (1 + i)^t. Both assume a constant rate, which real inflation does not.
Savings that do not keep up
A deposit whose interest is below inflation loses purchasing power even if the rupee balance rises. That is a planning observation, not a reason to chase unsafe returns.

Frequently asked questions
Should I use CPI as my inflation rate?
CPI is a national average. Your basket — rent, school fees, healthcare — can inflate faster. Use a rate that matches the costs you care about, and treat the result as a range, not a forecast.
