In this guide, we'll cover:

• What inflation is and how it's measured (CPI)

Key Concepts

Purchasing Power

Purchasing power refers to the quantity of goods or services that one unit of currency can buy. Example: If inflation is 3%, a $1.00 loaf of bread will cost $1.03 next year. Your $1.00 bill has lost 3% of its buying power.

Future Value

Formula: Future Value = Present Value / (1 + Inflation Rate)^Years

If you have $10,000 today and inflation averages 3% for 10 years, that $10,000 will only buy about $7,440 worth of goods in today's terms.

How to Beat Inflation

To maintain your standard of living, your investments must grow faster than inflation.

1. Invest in Stocks: Historically, the S&P 500 returns ~10% (7% real return after inflation).
2. Real Estate: Property values and rents typically rise with inflation.
3. TIPS (Treasury Inflation-Protected Securities): Government bonds indexed to inflation.
4. Avoid Excess Cash: Cash in a checking account earning 0.01% is guaranteed to lose value.

FAQ

Q: Is deflation good? A: Generally no. While lower prices sound good, deflation often signals a shrinking economy, leading to job losses and lower wages.

Q: How does inflation affect my debt? A: Inflation actually helps borrowers. If you have a fixed-rate mortgage, you are paying back the loan with "cheaper" dollars in the future.
