Simple road trip math, without the hassle
Road Trip Fuel Cost Calculator combines route distance with your vehicle's fuel economy and the latest published U.S. fuel-price data. The calculation itself is deterministic, so the final number is based on the route, MPG and price — not an AI guess.
Latest U.S. fuel pricesFuel-price defaults come from the U.S. Energy Information Administration's latest published national averages. You can override the price with your local station price.
Your actual MPGUse the MPG shown by your vehicle, its EPA rating, or your own real-world average for a more useful estimate.
Round trip + tollsTurn on round trip when you're returning to your starting point and optionally add your expected tolls. Per-person cost is calculated automatically.
How the calculation works
We calculate route distance first, then estimate gallons from distance ÷ MPG, and multiply the fuel used by the selected fuel price. Round-trip distance and optional tolls are included when selected.
