The national average gas price when Biden left office was about $3.12 per gallon in January 2025. That figure comes from AAA-based reporting cited in a fact check, which also notes it was lower than the June 2022 peak of $5.02 per gallon.

Quick context

  • When he took office: about $2.39 per gallon.
  • When he left office: about $3.12 per gallon.
  • Peak during his term: about $5.02 per gallon in June 2022.

Why it matters

That means gas was still well above the level at the start of his presidency, but far below the 2022 high point.
