What Is Inflation?
Inflation is the rate at which the general level of prices for goods and services rises over time. When inflation occurs, each dollar you own buys less than it did before. The same $100 bill that bought a full cart of groceries in 2010 might only fill half a cart today. Understanding inflation is essential for saving, investing, retirement planning, and making financial decisions that preserve your purchasing power over the long term.
How Inflation Is Measured
The most commonly used measure of inflation in the United States is the Consumer Price Index (CPI), published monthly by the Bureau of Labor Statistics (BLS). The CPI tracks the price changes of a representative basket of goods and services that typical households purchase, including:
- Food and beverages — groceries, restaurant meals, alcoholic beverages
- Housing — rent, mortgage costs (imputed), utilities, furniture
- Transportation — new and used vehicles, gasoline, airfare, public transit
- Medical care — health insurance, prescription drugs, doctor visits
- Education and communication — tuition, postage, phone service
- Recreation — pets, sports equipment, entertainment
The Federal Reserve targets a long-term inflation rate of 2% per year, which it considers optimal for a healthy economy. At 2% inflation, prices double approximately every 36 years (using the Rule of 72).
Historical Inflation in the United States
Understanding history helps put current inflation in perspective:
- 1913-2025 average: ~3.2% annually
- 1950s-1960s: Relatively low, averaging 1-3%
- 1970s-early 1980s: High inflation ("The Great Inflation"), peaking at 14.8% in 1980
- 1990s-2019: Moderate inflation, averaging 2-3%
- 2021-2023: Post-pandemic surge, peaking at 9.1% in June 2022 (highest in 40 years)
- 2024-2025: Inflation moderating toward the Fed's 2% target
The purchasing power of the US dollar has declined dramatically over the long term. What cost $1 in 1913 costs about $31 today — meaning the dollar has lost roughly 97% of its purchasing power over that period.
How Inflation Affects Different Assets
Cash and Savings Accounts
Cash held in a checking account or under a mattress loses purchasing power every day due to inflation. If inflation is 3% and your savings account earns 0.5%, your money is losing 2.5% of its purchasing power per year. High-yield savings accounts (currently offering 3.5-5.0% APY) can help offset inflation, but may not fully outpace it after taxes.
Bonds and Fixed Income
Traditional bonds are particularly vulnerable to inflation. If you own a bond paying 3% interest and inflation rises to 5%, your real return is -2%. This is why bond prices fall when inflation rises. Treasury Inflation-Protected Securities (TIPS) are designed to address this by adjusting their principal value with inflation.
Stocks
Equities have historically been a good hedge against inflation over the long term. Companies can raise prices to keep pace with inflation, which supports revenues and earnings. The S&P 500 has delivered an average annual return of approximately 10% (before inflation) over the long term, providing a significant real return above inflation. However, stocks can be volatile during periods of rapidly rising inflation.
Real Estate
Real estate has historically been one of the best inflation hedges. Property values and rental income tend to rise with inflation. Fixed-rate mortgages become cheaper in real terms as inflation rises. During the 1970s high-inflation period, real estate significantly outperformed most other asset classes.
Commodities and Precious Metals
Gold, silver, oil, and other commodities often rise during inflationary periods. Gold is frequently viewed as an "inflation hedge," though its performance has been mixed — it soared during the 1970s inflation but delivered poor returns during the 1980s-1990s when inflation was low.
Strategies to Protect Your Money from Inflation
Invest, Don't Just Save
The most important strategy is to keep your long-term savings invested rather than in cash. Even a modest stock/bond portfolio has historically outpaced inflation by a wide margin over 10+ year periods.
Use I Bonds and TIPS
Series I Savings Bonds from the US Treasury earn a rate that adjusts with inflation. They are one of the safest ways to ensure your savings keep pace with rising prices. TIPS (Treasury Inflation-Protected Securities) serve a similar function in a diversified bond portfolio.
Own Real Assets
Real estate, infrastructure, and commodities are real assets whose values tend to rise with inflation. REITs (Real Estate Investment Trusts) provide exposure to real estate without the hassle of direct ownership.
Review Your Retirement Projections
Retirement calculators often assume a 3-4% inflation rate. If actual inflation runs higher, your retirement savings may not support the lifestyle you expect. Use our Inflation Calculator to adjust your retirement projections for higher inflation scenarios.
Wage Inflation vs Price Inflation
An important distinction: if your income rises at the same rate as inflation, your purchasing power stays roughly the same. The problem occurs when prices rise faster than wages — which happened during the 2021-2023 period when real wages (wages adjusted for inflation) fell for many workers. This is why labor unions and workers push for cost-of-living adjustments (COLAs) in employment contracts.
Social Security recipients receive an annual Cost-of-Living Adjustment (COLA) based on CPI-W. In 2024, the COLA was 3.2%, down from 8.7% in 2023 (the highest in 40 years).
