Price in 2026 dollars = observed annual price × (2026 all-items CPI ÷ that year's all-items CPI). This measures overall purchasing power using the U.S. inflation index; the latest CPI year may be incomplete.
Average prices describe price levels. Changes in the products and stores sampled can affect these averages; category CPI controls for such changes and can follow a different path. Read the BLS explanation of average prices versus indexes.
