How inflation is calculated

Inflation is measured by the Consumer Price Index (CPI) — a basket of everyday goods and services tracked over time. To convert past money into today's value, you multiply by the ratio of today's CPI to the CPI of that year. This tool uses US CPI-U annual averages. Values between reference years are interpolated, so figures are close estimates rather than official numbers.

Which country's inflation is this?
United States (CPI-U, all urban consumers). It is a good global reference, though your local inflation may differ.
Why do prices rise so much over decades?
Even "low" 2–3% inflation compounds. Over 30 years, prices roughly double or triple — which is why long-ago prices feel tiny today.
