What Is Inflation?

Inflation is the rate at which the general level of prices for goods and services rises over time, which correspondingly decreases the purchasing power of money. If inflation is 3% per year, something that costs $100 today will cost $103 next year. Over 20 years at 3% inflation, that same item costs $181.

The Federal Reserve targets approximately 2% annual inflation as a healthy level that encourages spending and investment while maintaining price stability. When inflation runs significantly above this target — as it did in 2021–2023 — it can significantly erode household purchasing power.

How Inflation Affects Your Savings

Inflation is particularly damaging to cash and low-yield savings. If you keep $10,000 in a traditional savings account earning 0.5% interest while inflation runs at 3%, your money loses approximately 2.5% of its purchasing power every year. After 10 years, your $10,000 has the purchasing power of only about $7,760 in today's dollars.

This is why keeping large amounts of cash for extended periods is a losing strategy. The goal is not just to preserve the nominal value of money, but to preserve — and ideally grow — its purchasing power.

The Real Rate of Return

The real rate of return is your investment return after subtracting inflation. If your portfolio earns 8% and inflation is 3%, your real rate of return is approximately 5%. This is the actual increase in your purchasing power. Use our Real Rate of Return Calculator to calculate your inflation-adjusted returns.

Best Strategies to Beat Inflation

  • Invest in equities: Historically, the stock market has returned 7–10% annually, well above long-term inflation rates. Equities are the most reliable long-term inflation hedge for most investors.
  • Real estate: Property values and rents tend to rise with inflation, making real estate a natural inflation hedge.
  • Treasury Inflation-Protected Securities (TIPS): U.S. government bonds whose principal adjusts with inflation, guaranteeing a real (inflation-adjusted) return.
  • I-Bonds: U.S. savings bonds that earn interest tied to the inflation rate, offering a safe, inflation-protected return on up to $10,000 per year.
  • High-Yield Savings Accounts: During periods of high inflation and high interest rates, HYSAs can offer competitive real returns. Always compare the HYSA rate to the current inflation rate.

What to Avoid During High Inflation

  • Long-term fixed-rate bonds: Rising inflation erodes the real value of fixed bond payments.
  • Excessive cash holdings: Cash loses purchasing power at exactly the inflation rate.
  • Taking on variable-rate debt: Inflation often leads to higher interest rates, making variable-rate loans more expensive.

The Bottom Line

Inflation is an unavoidable economic reality. The best defense is a diversified investment portfolio weighted toward equities, combined with an emergency fund in a high-yield savings account. Use our Inflation Calculator to see exactly how inflation affects the future purchasing power of your money.
