How it works

Adjusted amount = original × (CPI in target year / CPI in base year). The US Bureau of Labor Statistics publishes CPI-U monthly. $1 in 1980 equals about $3.70 today. Inflation compounds: 3% per year doubles prices in 24 years (Rule of 72). Core CPI excludes food and energy; PCE (Fed's preferred measure) weights consumption differently. Future inflation is projected, not guaranteed.
