Common questions

What is $100 in 1985 worth in 2010?
About $203, an increase of 102.7% over 25 years (roughly 2.87% 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 1985 into $203 in 2010 if inflation were constant. Useful for comparing decades that had very different inflation patterns (e.g., 1970s vs 2010s).
