How inflation rates are determined

Historical inflation calculations apply CPI-U averages released by the US Bureau of Labor Statistics (BLS). The index converts equivalent purchasing power using: Equivalent = Amount × (Target CPI / Base CPI).

Future projections apply standard compound annual decay rates. Real values model purchasing power relative to custom commodity weights.
