How Inflation is Calculated

This tool uses the Consumer Price Index (CPI) provided by the Bureau of Labor Statistics. The CPI represents the average change over time in the prices paid by urban consumers for a market basket of consumer goods and services.

To find the equivalent value, we use the formula:
Value in End Year = Amount × (CPI in End Year / CPI in Start Year)

Inflation effectively reduces the "purchasing power" of your money, meaning that the same amount of dollars buys fewer goods today than it did in the past.
