RV Trip Cost Calculator

Build a realistic RV or travel-trailer trip budget beyond fuel alone.

Updated 2026-08-12

RV trip cost equals towing fuel plus campground nights, booking charges, propane, generator fuel and tolls. Use measured towing MPG because an unloaded vehicle MPG estimate can materially understate the trip.

What makes an RV trip budget different

Towing MPG or motorhome MPG can be far below the unloaded vehicle figure.
Campground nights can cost more than fuel on a slow itinerary.
Propane, generator fuel, reservation charges and tolls are easy to omit.
Higher cruising speed can increase fuel consumption even when it shortens pure driving time.

Use a measured towing MPG

For the best estimate, reset the trip computer after hitching and use fuel purchased divided by miles travelled across several tanks. Headwind, terrain, speed and trailer frontal area can move one trip well away from the average.

Frequently asked questions

How do I estimate towing fuel cost?

Divide trip miles by towing MPG, then multiply gallons by fuel price. Use towing MPG rather than the unloaded truck figure.

Does this include campground fees?

Yes. Enter paid nights, nightly rate and reservation fees. Free overnight stops can be entered as zero-cost nights.

Why does towing reduce MPG?

A trailer adds mass, rolling resistance and substantial aerodynamic drag. Speed, frontal area and wind can have a large effect.
