What is the current US inflation rate?

The US inflation rate fluctuates year to year. The long-run historical average from 1913 to 2024 is approximately 3.1% per year. Inflation peaked at 9.1% in June 2022 and has since moderated to around 2–3% in 2025–2026.

How does inflation affect savings?

If your savings earn less than the inflation rate, you are losing real purchasing power. $10,000 in a 0.5% savings account loses value in real terms when inflation is 3%. This is why investing in assets that outpace inflation (stocks, real estate, TIPS) is important for long-term wealth.

What is the Rule of 72 for inflation?

Divide 72 by the inflation rate to estimate how many years it takes for prices to double. At 3% inflation, prices double every 24 years. At 6% inflation, prices double every 12 years.
