What is Inflation and How Does It Affect Your Money?

Inflation is the rise in prices over time, which means the same dollar buys less in the future. In practical terms, inflation can reduce the real value of savings, wages, and fixed cash reserves if returns do not keep pace.

How is the Inflation Rate Calculated? (CPI Method)

A common method uses the Consumer Price Index, or CPI. The calculator compares the CPI of two years, then applies the ratio to determine how much money from one period would be worth in another. That provides a clear estimate of historical purchasing power.

Why Tracking Purchasing Power Matters for Long-term Investors

Long-term investors care about real returns, not just nominal gains. If inflation rises faster than your portfolio, your purchasing power can shrink. Monitoring inflation helps you set realistic goals, evaluate cash holdings, and plan for retirement with more precision.
