1. What is Inflation Rate?

The inflation rate measures the percentage change in price levels between two periods, typically calculated using the Consumer Price Index (CPI). It indicates how much prices have risen over time, affecting purchasing power and economic decisions.

2. How Does the Calculator Work?

The calculator uses the inflation rate formula:

Where:

• \( CPI_{\text{start}} \) — Consumer Price Index at the starting date
• \( CPI_{\text{end}} \) — Consumer Price Index at the ending date

Explanation: The formula calculates the percentage change in price levels by comparing the difference between two CPI values relative to the starting CPI.

3. Importance of Inflation Calculation

Details: Inflation rate is a key economic indicator used by policymakers, businesses, and consumers to make informed decisions about investments, wages, and pricing strategies.

4. Using the Calculator

Tips: Enter both CPI values (starting and ending) in the appropriate fields. Both values must be positive numbers representing valid CPI index values.
