The U.S. national average gas price around the time Biden left office was about $3.10 per gallon , based on reports comparing it with the later 2026 average of about $4.16 and saying prices then were lower than during 91% of Biden’s presidency.

What that means

  • That figure refers to the national average , not every state or city.
  • Gas prices vary a lot by region, taxes, and local supply conditions, so your area could have been above or below that level.
  • If you want the most precise answer for the exact day he left office, it would usually come from the Energy Information Administration’s daily retail gasoline data, but the available sources here support the roughly $3.10/gal range.

Quick context

Prices were already moving around in early 2025, so a single day’s price can be misleading. For a “when Biden left office” framing, the best shorthand is that gas was a little above $3 per gallon nationally.
