US inflation calculator

Convert a US dollar amount between two years using CPI-U annual averages (1913–2024, BLS CUUR0000SA0).

Computed in this browser. Nothing is sent anywhere.

Uses the US CPI-U annual average (BLS series CUUR0000SA0, 1982–84 = 100), 1913–2024. It answers "what is $X from year A worth in year B dollars" — an index conversion, not a price quote for specific goods.

How to use

  1. Enter the amount.
  2. Pick the from and to years.
  3. See the converted amount and the change.

What it supports

Uses annual-average CPI-U for US urban consumers — a purchasing-power estimate between calendar years, not monthly precision, not investment returns, and not a cost-of-living comparison for other countries.
