US Trip Cost Calculator: Gas, Tolls & Cost to Drive

Enter your start and destination, set your vehicle's MPG, and the calculator converts the route distance into gallons at current state gas prices, then adds the tolls for every turnpike, bridge and tunnel along the way. Gas and tolls are shown as separate lines plus one combined total, so you can see which one is really driving the cost.

As a rough benchmark, a 1,000-mile road trip in a 30 MPG car burns about 33 gallons — roughly $110 at $3.30 a gallon — plus tolls, which run from nothing across most of the West to $30 or more through the Northeast corridor. Enter your actual route and MPG and the road trip cost calculator replaces that estimate with a real figure.

The simple version is miles divided by MPG, multiplied by the gas price, plus tolls. The honest version also counts depreciation, insurance, tires and maintenance — the IRS standard mileage rate puts the all-in figure at 67 cents per mile for 2024. This calculator shows both, so you can budget fuel with the first number and compare against flying with the second.

Yes. Gas prices are refreshed daily and applied per state, because a gallon in California and a gallon in Texas can differ by more than a dollar. If you know you will fill up somewhere cheaper, override the price and the trip fuel cost calculator recalculates instantly.

Tolls are estimated for every state that charges them, including the major turnpike systems in Pennsylvania, Ohio, Indiana, Illinois, Florida, Texas and across the Northeast. Where a transponder such as E-ZPass or SunPass earns a lower rate, that discount is applied instead of the cash rate.

Completely free, with no sign-up and no usage limits. Nothing you enter — routes, MPG, or gas prices — is stored on our servers; your settings stay in your own browser.

Both. It is a trip calculator for gas and tolls together: the route is converted into gallons at your MPG and priced at current state gas prices, then every turnpike, bridge and tunnel along the way is added as its own toll line. Read the gas figure on its own if that is all you need, or take the combined total as the real cost to drive.
