One of the most overlooked expenses when planning a caravan trip is fuel. A heavy vehicle, extra load, and usually a less aerodynamic body mean caravans burn noticeably more fuel than a regular passenger car. Use the calculator below to enter your distance, average consumption, and current fuel price to instantly see the estimated fuel cost of your trip.

Factors That Affect Caravan Fuel Consumption
- Vehicle weight: a caravan with full water tanks and loaded equipment burns noticeably more fuel than an empty one.
- Aerodynamics: tall, boxy caravan bodies increase air resistance significantly, especially at highway speeds.
- External equipment like awnings and bike racks: every part mounted on the outside of the vehicle creates extra drag.
- Tire pressure and maintenance condition: low tire pressure increases rolling resistance and raises consumption.
- Driving style and speed: steady, moderate-speed driving saves noticeably more fuel than constant acceleration and braking.
Average Consumption for Motorhomes and Travel Trailers
Motorhomes, since they move under their own engine and generally carry a heavier body, consume in the 12-20 L/100km range on average; larger models (over 7 meters) can run even higher. Panel-van based camper box conversions, having a standard commercial vehicle engine, stay around 8-12 L/100km. Travel trailers don’t have their own fuel consumption, but the towing vehicle’s consumption can increase by 20-40% compared to towing nothing, due to the caravan’s weight and aerodynamic drag.
Frequently Asked Questions
How accurate is this calculator for my real consumption? The calculation is based on the average consumption figure you enter and is an estimate. Actual consumption can differ by 10-20% depending on load, wind, road gradient, and driving style.
How can I find out my caravan’s actual fuel consumption? Fill the tank completely, drive a few hundred kilometers, then fill it again; divide the liters used by the distance covered and multiply by 100 to get your own L/100km figure.
How much does towing a travel trailer increase fuel use? Depending on the caravan’s weight and aerodynamic drag, the towing vehicle’s consumption typically increases by 20-40%.
