How Inflation Affects Your Money
Inflation means the same amount of money buys less over time. At a 3% annual inflation rate, $100,000 today has the purchasing power of only $74,409 in 10 years. This is why keeping large amounts in savings accounts with low interest rates gradually erodes real wealth.
The US Federal Reserve targets 2% annual inflation as a healthy rate for the economy. From 2021–2023, inflation peaked at 9.1% (June 2022) — the highest since 1981 — before returning toward the 2–3% range by 2025–2026.
Frequently Asked Questions
US inflation (CPI) was approximately 2.4%–2.9% in early 2026, down from the peak of 9.1% in June 2022. The Federal Reserve targets 2% annual inflation. Check BLS.gov for the most current monthly CPI data.
At 3% annual inflation, $100,000 loses about $3,000 in real purchasing power each year. After 10 years, you'd need $134,392 to have the same buying power as $100,000 today. If your savings account earns less than inflation, you are losing real wealth each year even as the balance number grows.
Years to halve purchasing power = 70 ÷ Inflation Rate. At 2% inflation → 35 years to halve. At 3% → 23 years. At 7% (near 2022 peak) → just 10 years. This rule helps quickly estimate the long-term erosion of money's value.
Best strategies: (1) Stock market index funds — historically ~7% real return above inflation. (2) TIPS (Treasury Inflation-Protected Securities) — adjust with CPI automatically. (3) I-Bonds — earn fixed rate plus CPI rate, max $10,000/year. (4) Real estate — typically appreciates with or above inflation. (5) High-yield savings accounts when rates exceed inflation rate.
