Sources and calculation method
- Where do the prices come from?
- BLS Average Price Data, series APU000074714: Gasoline, unleaded regular, per gallon/3.785 liters. The local price dataset was updated on 2026-07-27. Monthly figures are BLS retail price estimates. They describe price levels; CPI measures price change.
- How is the annual average calculated?
- Fiat Watch takes the arithmetic mean of the available published monthly prices and stores it to three decimal places. These annual figures are calculated by Fiat Watch from BLS observations. Missing months are not filled in; fewer than twelve observations means the average covers only part of the year.
- How are prices adjusted for inflation?
- Original price × CPI-U in 2026 ÷ CPI-U in the original year. The index is Consumer Price Index for All Urban Consumers (CPI-U), U.S. city average, all items, series CUUR0000SA0. CPI data was updated on 2026-05-27. April CPI is used for 2026 until the annual average is published. This comparison estimates general purchasing power. It does not measure product-specific inflation or a local household's spending.
