Understand how inflation erodes your purchasing power with the US Inflation Calculator. Using Consumer Price Index (CPI) data, see what yesterday's dollars are worth today and plan accordingly.
Inflation is the silent wealth destroyer. Over time, even moderate 3% inflation dramatically reduces what your money can buy. Understanding inflation's impact is essential for retirement planning, salary negotiations, and investment decisions.
This shows how much a dollar amount from the past would need to be today to maintain the same purchasing power.
$50,000 salary in 2000 has the same purchasing power as ~$92,000 in 2024. If your salary hasn't kept pace, you've effectively taken a pay cut!

CPI measures price changes of a basket of goods. Inflation = (Current CPI - Previous CPI) ÷ Previous CPI × 100. Historical average is ~3% annually.
Using average 3% inflation: $100 × 1.03^24 ≈ $203. You'd need $203 in 2024 to buy what $100 bought in 2000. That's 103% cumulative inflation!
Invest in assets that outpace inflation: stocks (7-10%), real estate, I-Bonds, TIPS. Cash and savings accounts typically lose purchasing power over time.
