See how inflation affects your money's purchasing power over time. Enter a dollar amount, inflation rate, and time period to see how much more things will cost in the future — or how much less your money will buy.
Inflation is the rate at which the general level of prices rises, causing purchasing power to fall. When inflation is 3%, something that costs $100 today will cost $103 next year.
Over long periods, inflation's compound effect is dramatic. At 3% inflation, prices double every ~24 years. What costs $100 today cost $50 in 2000 and will cost $200 by 2048.
This is why investing is essential — money sitting in a checking account loses value every year. Your investments need to earn at least the inflation rate just to maintain purchasing power.

Oil shocks drove inflation to 14.8% in 1980. The Fed raised interest rates to 20% to combat it, causing a deep recession.
Zimbabwe (2008), Venezuela (2018), and Weimar Germany (1923) saw monthly inflation rates exceeding 50%. Currency becomes essentially worthless.
Home prices have risen ~5% annually long-term. Rent increases 3-7% per year in most metro areas. Housing typically outpaces general inflation.
Medical costs rise 5-8% annually — significantly faster than general inflation. Insurance premiums, drugs, and procedures all accelerate.
College tuition has risen 5-8% annually for decades. A degree costing $40K in 2000 costs $100K+ today.
Food prices average 2-4% annual increase but can spike 8-10% during supply disruptions, droughts, or energy crises.
At 0.5% interest vs 3% inflation, you lose 2.5% purchasing power yearly. HYSA rates of 4-5% now beat inflation.
30 years of 3% inflation means you'll need 2.4× more money in retirement than today. Plan accordingly.

US inflation as measured by CPI has been running at approximately 3-4% in recent periods. The Federal Reserve's target is 2%. Check the Bureau of Labor Statistics (BLS) for the latest data.
If your savings earn less than inflation, you're losing purchasing power. $10,000 at 0.5% interest with 3% inflation loses ~$250 in real value per year. Use high-yield savings or invest to beat inflation.
Main causes: increased money supply (monetary policy), rising costs (cost-push), increased demand (demand-pull), and supply disruptions. Central banks use interest rates to control inflation.
Invest in assets that historically outpace inflation: stocks (7-10%/yr), real estate (5-8%/yr), TIPS bonds, commodities, and I-Bonds. Avoid holding excess cash in low-interest accounts.
Divide 72 by the inflation rate to find how many years until prices double. At 3% inflation: 72 ÷ 3 = 24 years. At 6%: 72 ÷ 6 = 12 years.
