How much does towing increase fuel cost?
It depends on trailer type and speed, but many drivers see 10-30% higher fuel cost per trip.
Estimate MPG drop and trip fuel cost when towing a trailer, boat, or camper.
Base fuel used: 23.52 L
Towing fuel used: 28.68 L
Extra fuel due to towing: 5.16 L
Total towing trip cost: $43.03
Towing increases aerodynamic drag and engine load, which often reduces MPG. Trailer weight, shape, speed, road gradient, wind, and tire pressure all influence the final fuel cost.
Use this towing fuel cost calculator to compare base vehicle fuel spend vs towing trip spend before long travel. It helps estimate realistic budget for towing a boat, camper, or utility trailer.
Towing almost always reduces fuel economy because the engine works harder to move extra weight and overcome additional aerodynamic drag. Highway driving often shows the biggest drop, especially with tall trailers and strong headwinds.
For more accurate planning, use your usual cruising speed, realistic payload, and expected terrain. A 10-30% MPG drop is common depending on trailer type, load shape, and road conditions.
Often around 10-15% MPG reduction.
Commonly around 15-25% MPG reduction.
Can reach 25-40% MPG reduction.
It depends on trailer type and speed, but many drivers see 10-30% higher fuel cost per trip.
Use the value closest to your route profile. For mixed routes, use a conservative combined estimate.
Yes. Select camper-style drop assumptions and run multiple fuel price scenarios for trip budgeting.
