Frequently Asked Questions

What is the average inflation rate?

US inflation has averaged about 3% since 1913. Recent years (2021-2023) saw higher inflation (6-9%). The Federal Reserve targets 2% annual inflation.

How does inflation affect my savings?

If your savings earn less than inflation, you lose purchasing power. At 3% inflation, $100,000 has the buying power of only $55,000 after 20 years.

How do I protect against inflation?

Invest in assets that historically beat inflation: stocks (7-10% real return), real estate, I-bonds, and TIPS. Avoid keeping large amounts in low-yield savings accounts.

What is the rule of 72 for inflation?

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