How to use this towing capacity calculator

Enter the requested values above and select Calculate. Change any input to compare scenarios.

Formula and method

GCWR-limited trailer capacity = GCWR − loaded vehicle weight. Planning maximum = the lower of that value and the manufacturer-rated towing capacity.

Example

If GCWR is 14,000 lb and the loaded vehicle weighs 6,000 lb, the combination rating allows 8,000 lb before considering the manufacturer tow rating and other limits.

Important assumptions

This is not a vehicle-specification lookup. Never exceed the vehicle, hitch, axle, tire, tongue-weight or manufacturer ratings. Verify your owner’s manual and labels.
