Trailer weight and vehicle payload calculator

Check vehicle, trailer, combined and hitch limits separately. Include passengers, cargo and hitch hardware; use measured tongue load or an explicit percentage and export the report.

Enter ratings from the exact vehicle and hitch documentation and masses for the actual loaded trip. Blank values are not zero. The example button loads fictional figures, not specifications for your vehicle.

Tongue load consumes vehicle payload but must not be counted twice in combined mass. This simplified calculation does not model weight-distribution hitches, axle loads, tyres, brakes, stability or legal requirements. Verify weights on scales and follow the manufacturer’s limits.
