Understanding Inflation

Inflation is the rate at which the general level of prices for goods and services rises, eroding purchasing power over time. Understanding inflation is crucial for financial planning, retirement savings, and investment decisions.

How Inflation Works

When inflation occurs, each unit of currency buys fewer goods and services. For example, if inflation is 3% per year, something that costs $100 today will cost $103 next year. Over longer periods, this compounding effect becomes significant.

Historical Inflation Rates

Period	Average US Inflation
1990-2000	2.9%
2000-2010	2.5%
2010-2020	1.8%
Long-term Average	~3%

Protecting Against Inflation

• Invest in Stocks: Historically outpace inflation over long periods
• Real Estate: Property values often rise with inflation
• TIPS: Treasury Inflation-Protected Securities adjust for inflation
• I Bonds: Savings bonds with inflation-adjusted rates
• Commodities: Gold and other commodities can hedge inflation

The Rule of 72 for Inflation

Divide 72 by the inflation rate to estimate how many years until prices double. At 3% inflation, prices double approximately every 24 years (72 ÷ 3 = 24).
