Understanding Inflation and Purchasing Power

Inflation measures the rate at which the general level of prices for goods and services rises, eroding purchasing power over time. The Consumer Price Index (CPI), published by the Bureau of Labor Statistics, is the most widely used measure of inflation in the United States.

Even moderate inflation of 3% per year means prices roughly double every 24 years. This is why understanding inflation is critical for retirement planning, salary negotiations, and long-term investment decisions. Money sitting in a savings account earning less than the inflation rate is actually losing value in real terms.

Historical US inflation has averaged about 3.3% annually since 1970, though it has varied dramatically — from deflation in 2009 to over 13% in 1980 and 8% in 2022. The Federal Reserve targets a 2% annual inflation rate as its long-term goal.
