A trucking mileage calculator turns loaded and deadhead miles into the numbers that actually run a truck: fuel cost, break-even rate, and per-state IFTA mileage. Enter 400 loaded miles, 90 deadhead miles, 6.5 mpg, and $3.89 diesel, and the tool returns a fuel bill, a break-even rate, and a real profit figure, not just a distance.

How to use it

Enter loaded and deadhead miles, then set fuel economy (mpg) and diesel price per gallon. Pull diesel from the EIA weekly retail on-highway index to match broker fuel-surcharge clauses. Truck routing avoids low bridges, weight-restricted roads, and commercial vehicle bans, so the mileage figure matches what a Class 8 tractor-trailer can legally drive, unlike a car navigation app. For height clearance, plan on 13 ft 6 in (4.11 m) for a standard dry van or 14 ft (4.27 m) for a tall reefer or stepdeck.

Practical miles, shortest miles & HHG miles

Three mileage standards exist in US trucking, and confusing them costs real money. Practical miles follow the route a truck would realistically drive, favoring interstates over back roads, and most carriers pay on this standard. Shortest miles minimize distance without regard for road class, often routing through towns a 53 ft (16.15 m) trailer can’t clear. Household goods (HHG) miles come from a ZIP-to-ZIP lookup table originally built for moving companies, and many brokers still quote from it.

A 41-mile gap you either eat or bill for. Check your rate confirmation before you accept the load, since the document names the standard being used.

Deadhead & out-of-route miles

Deadhead miles cut your effective rate per mile since every empty mile gets paid at zero. A load quoting $2.60/mile over 400 loaded miles pays $1,040. Drive 90 empty miles to the shipper and your real rate drops to $2.12 across 490 total miles, a 48-cent swing that never appears on the rate confirmation.

Per-state mileage for IFTA

IFTA covers 48 US states and 10 Canadian provinces. Returns are due quarterly: April 30, July 31, October 31, and January 31. Two figures go on the return: total miles (every mile, loaded or empty) and taxable miles, which exclude jurisdiction-specific exemptions like Oregon toll miles. A run from Atlanta to Newark crosses 7 jurisdictions, so the return needs 7 separate entries plus fuel receipts for each. Keep trip sheets and odometer readings for 4 years, the standard IFTA audit window.

Legal drive days

FMCSA hours-of-service rules cap driving at 11 hours inside a 14-hour on-duty window, followed by 10 consecutive hours off. Based on total trip miles, a 55 mph average runs about 605 legal miles a day, so LA to Chicago at 2,015 miles needs 4 duty days minimum once mountain grades and required breaks are accounted for. Weekly limits still apply: 60 hours in 7 days or 70 in 8, resettable with a 34-hour restart.

What a truck mile costs

Industry average operating cost reached $2.336/mile, the highest ever recorded, per the American Transportation Research Institute (ATRI). Tolls rose 13.2%, repair and maintenance 8.6%, driver benefits 6.6%, and tires 6.4% year over year. The Northeast is priciest at $2.52/mile; the South-Central US lowest at $2.23/mile. Fuel holds steady around $0.482/mile.

4 states that tax mileage outside IFTA

• Kentucky (KYU): weight-distance permit, 60,000 lb and up, filed quarterly.
• New Mexico (WDT): weight-distance tax, 26,000 lb and up.
• New York (HUT): highway use tax certificate and sticker, 18,000 lb and up.
• Oregon: weight-mile tax instead of a pump tax, reported monthly.
