What is inflation impact?

Inflation reduces how much a fixed amount of money can buy over time. The same rupee amount later usually buys less, so costs that feel affordable today may need a larger nominal amount in the future.

Formula

Future equivalent cost (FV) = Amount × (1 + i)^years
Purchasing power later = Amount ÷ (1 + i)^years
Amount needed later to match today’s purchasing power = FV (same as future equivalent cost)

i = inflation rate (decimal)

Example

₹1,00,000 at 6% inflation for 10 years → future equivalent ≈ ₹1,79,085. Holding ₹1,00,000 unchanged has purchasing power ≈ ₹55,839 in today’s terms after 10 years.

FAQ

Is CPI the right inflation rate?

Personal inflation can differ from headline CPI (healthcare, education, rent). Use a rate that matches the expense you care about.

Does this include investment returns?

No. It isolates inflation. Combine with SIP/FD tools when modeling real (inflation-adjusted) growth.
