Analysis
Inflation erodes purchasing power; your adjusted value reflects the equivalent cost today.
Understanding the Impact of Inflation on Purchasing Power
The **Inflation Calculator** is a crucial tool for **financial planning** and understanding how the general rise in prices affects the value of money over time. **Inflation** causes a reduction in **purchasing power adjustment**; what $\$1$ bought last year requires more money today. This calculator allows you to project the equivalent cost of goods in the future or adjust historical costs to today's value, based on a fixed **annual inflation rate**.
The Inflation Calculation Formula
The **inflation calculation** uses the compound growth formula. The final value is determined by the initial value, the **annual inflation rate** ($r$), and the **duration (years)** ($t$):
The **cumulative inflation** percentage is derived from this formula and shows the total erosion of **purchasing power** over the entire period. This tool provides a reliable **cost of living increase** estimate.

To maintain **purchasing power**, your investments must earn a return higher than the **annual inflation rate**. Use the **Inflation Calculator** in conjunction with the **Compound Interest Calculator** to ensure your savings are keeping pace with the **cost of living increase**.
