(Towing Distance / Towing MPG) × Fuel Price
Accurately calculates heavy hauling and travel trailer itineraries where aerodynamic and inertia drag cut fuel economy in half.

How Towing Fuel Cost Calculator Works?

This tool works by dividing the towing distance by your towing miles per gallon (MPG) and multiplying by the fuel price. The result is the fuel cost of pulling a trailer, boat, or camper.

  1. Enter towing distance

    Type the miles you tow, for example 400 miles (644 km).

  2. Enter towing MPG

    Type the MPG with the trailer attached. Towing cuts MPG by 30% to 50% for most pickups and SUVs.

  3. Enter the fuel price

    Type the price per gallon.

  4. Read the towing cost

    The tool returns the fuel cost of the towing leg.

Towing Fuel Cost Calculator Formula

The formula is Towing Cost = (Towing Distance ÷ Towing MPG) × Fuel Price.

Formula
Towing Cost = (Towing Distance ÷ Towing MPG) × Fuel Price

Formula variables

Towing Distance
Miles driven with the trailer attached.
Towing MPG
Fuel economy while towing.
Fuel Price
Dollars per US gallon (3.785 L).

Worked example

  • Towing Distance: 400 miles
  • Towing MPG (e.g. trailer/boat): 12 MPG
  • Fuel Price: $3.80/gal
  1. Gallons: 400 ÷ 12 = 33.33 gallons (126.2 L).
  2. Cost: 33.33 × $3.80 = $126.67.

Result: $126.67 ($ towing cost)

The same truck rated 20 MPG unloaded spends $76.00 on 400 miles at $3.80. Towing at 12 MPG adds $50.67 to the trip.

Values held constant: Fuel Price = $3.80/gal.

Towing a heavy fifth-wheel camper 800 miles (1,287 km) at 8 MPG costs $380.00 in fuel.

What is Towing Fuel Cost Calculator?

The Towing Fuel Cost Calculator is a tool that prices the fuel used while towing a trailer, boat, or camper. The tool uses towing MPG, not the vehicle's normal rating.

Trailers add weight and aerodynamic drag. A 5,000-pound (2,268 kg) travel trailer often drops a pickup from 20 MPG to 10 to 12 MPG.

Measuring towing MPG on a short test run gives the most accurate input for long trips.

What are the uses of Towing Fuel Cost Calculator?

There are 4 main uses of the Towing Fuel Cost Calculator: budgeting RV trips, pricing boat launches, quoting hauling jobs, and planning horse trailer travel.

  • Budgeting RV trips

    Camper owners price fuel for each leg of a trip.

  • Pricing boat launches

    Boat owners include towing fuel in the cost of a lake day.

  • Quoting hauling jobs

    Contractors add towing fuel to equipment delivery quotes.

  • Planning horse trailer travel

    Riders budget fuel for show and event travel.
