Inflation Insights
Key concepts to understand about inflation and its impact on your finances.
What Is Inflation?
Inflation measures the rate at which the general level of prices for goods and services rises, eroding purchasing power. A steady, predictable inflation rate is ideal for economic stability.
The CPI Explained
The Consumer Price Index (CPI) is the primary measure of inflation in the U.S. It tracks the average change in prices paid by urban consumers for a basket of goods and services.
The 2% Target
The Federal Reserve targets a 2% inflation rate to maintain maximum employment and price stability. When inflation is stable, households can accurately predict their costs.
Inflation vs. Savings
If you keep money under your mattress, inflation erodes its value. To buy the same amount of goods that $1,000 could purchase in 1990, you would need over $2,400 today.
