Understand how inflation changes the real value of money across time.
Overview
Inflation reduces purchasing power, even when nominal income rises.
This calculator estimates future equivalent cost of today's expenses.
It also helps convert future amounts into present-value purchasing terms.
Using conservative inflation assumptions improves long-term planning.
Steps
Use present-day cost or income amount.
Use annual expected inflation assumption.
Set projection horizon length.
Review inflation-adjusted future amount.
Stress-test with higher and lower inflation scenarios.
Math
Future Amount = Present Amount × (1+i)^n
Inflation compounds over years, increasing nominal amount needed for same purchasing power.
Worked cases
Future = 1,000(1.03)^10
Future equivalent is about $1,344.
Future = 1,000(1.05)^10
Future equivalent rises to about $1,629.
Apply compounding over 25 years.
Long horizons significantly amplify inflation impact.
