1. What is the Inflation Rate?

The inflation rate measures the percentage change in the Consumer Price Index (CPI) over time, indicating how much prices for goods and services have increased or decreased.

2. How Does the Calculator Work?

The calculator uses the inflation rate formula:

Where:

• \( \text{CPI\_now} \) — Current Consumer Price Index value
