Understanding Inflation: A Comprehensive Guide
Inflation is the gradual increase in prices and the corresponding decline in the purchasing power of money over time. Our inflation calculator helps you understand how the value of money changes across different periods using historical Consumer Price Index (CPI) data from the U.S. Bureau of Labor Statistics.
What Is Inflation and Why Does It Matter?
Inflation measures how much more expensive a set of goods and services has become over time. A moderate inflation rate is normal in a healthy economy, but high inflation can erode savings and make planning for the future difficult.
Key inflation concepts:
- Purchasing Power: The amount of goods/services money can buy
- CPI (Consumer Price Index): Measures average price changes for consumer goods
- Deflation: When prices decrease (negative inflation)
- Hyperinflation: Extremely rapid inflation that destabilizes economies
