Frequently Asked Questions
Inflation is the rate at which prices increase over time, reducing purchasing power. If inflation is 3%, something costing $100 today will cost $103 next year. The Consumer Price Index (CPI) measures inflation in the US. Historical average is ~3% annually.
Inflation erodes purchasing power. At 3% inflation, $10,000 today buys only $7,374 worth of goods in 10 years. Your savings need to earn at least the inflation rate to maintain value. Stocks historically beat inflation; savings accounts often don't.
Real return = Nominal return - Inflation. If investments earn 8% and inflation is 3%, real return is ~5%. This is actual purchasing power gained. Always consider real returns when evaluating investments, especially for retirement planning.
Inflation hedges: stocks (historically beat inflation), real estate, TIPS (Treasury Inflation-Protected Securities), I-Bonds (up to $10k/year), commodities. Avoid long-term fixed income during high inflation. Diversification is key.
US CPI annual averages: 1920s: 0%, 1970s: 7.1%, 1980s: 5.6%, 2000s: 2.6%, 2010s: 1.8%, 2021-2022: 7-9%. Long-term average is ~3%. The Fed targets 2% inflation. High inflation (>5%) significantly impacts purchasing power.
