What would $10,000 in an earlier month buy at the latest Consumer Price Index reading? This page uses the official BLS CPI-U for all items, U.S. city average, not seasonally adjusted (series CUUR0000SA0). Example: $10,000 in Jan 2000 had the same purchasing power as $19,961 in Sep 2026 — a 2.00× rise in the price level.

Formula & source
CPI-U is a fixed-basket consumer-price index, not a personal cost of living and not an asset return. It is not seasonally adjusted. The BLS emblem is not used here.
The same CPI series powers the “Adjust for inflation” toggle on the investment calculator, which reports ending values in start-month dollars: real value = nominal value × (CPI at start ÷ CPI at the later month).
