Truck mileage + fuel cost

This calculator gives the truck-routable miles and drive time between two places, and the diesel cost for the trip at your MPG. Gallons = miles ÷ MPG; fuel cost = gallons × diesel price per gallon.

Two cities and your truck's MPG. We pull practical miles (truck-routable, not great-circle), drive time, and real diesel cost from this week's regional diesel average.

How fuel cost is calculated

Miles are practical driving routes from a mapping service. Diesel price is this week's retail on-highway average — regional if we can identify the origin state, national otherwise. Miles ÷ MPG = gallons; gallons × price = cost.

Heads-up: actual pump price varies ±50¢ from the regional average depending on the truck stop, so the fuel cost here is an estimate, not a receipt.

Truck mileage FAQ

Is there a free truck mileage calculator?

Yes — enter two cities above and you get practical truck-routable miles, estimated drive time, and the diesel cost for the trip at this week's regional average price. Free, no signup.

How do I calculate fuel cost for a trip?

Miles ÷ MPG × price per gallon. For example, a 700-mile run at 6 MPG and $3.90 diesel burns about 117 gallons — roughly $455 in fuel. This calculator does that math with real routed miles and current regional prices.

What's the difference between practical miles and shortest miles?

Practical miles follow routes a truck can actually drive — truck-legal roads, realistic routing — and are what most rate negotiations assume. Shortest miles cut through routes a Class 8 truck can't or shouldn't take, which understates the trip.

What is the fuel cost per mile for a truck?

Fuel cost per mile = diesel price per gallon ÷ MPG. For example, at $3.90 diesel and 6 MPG that's $0.65 per mile. This calculator shows the trip total; divide the fuel cost by the miles for the per-mile figure.

What is OverTheRoad.AI?

OverTheRoad.AI is an AI back office for owner-operators and small fleets.
