Common questions
- What is $100 in 1990 worth in 2020?
- About $198, an increase of 98.0% over 30 years (roughly 2.30% per year). Calculation uses the BLS Consumer Price Index for All Urban Consumers (CPI-U, series CUUR0000SA0), annual averages.
- Why does CPI-U sometimes feel lower than my actual cost of living?
- CPI-U is a national average across a fixed basket. Personal inflation can run higher if rent, healthcare or college tuition dominate your spending — those categories have risen faster than the headline index. CPI-U is the official benchmark used for Social Security COLAs and federal tax bracket adjustments.
- What does the CAGR figure mean?
- Compound annual growth rate: the smoothed yearly rate that turns $100 in 1990 into $198 in 2020 if inflation were constant. Useful for comparing decades that had very different inflation patterns (e.g., 1970s vs 2010s).
