Line shows CPI‑U annual average, indexed to your "from" year.
Figures use official CPI‑U annual averages fetched live from the BLS Public Data API where available. When live data can't be reached (rate limits, offline use), an embedded reference dataset is used instead — this is flagged above the result. Educational estimate only; consult bls.gov/cpi for the official record.
