Payload Calculator
You want to know how people, gear, and trailer hitch load use your vehicle’s rated payload.
Choose a focused tool
Towing Calculators
Choose the calculation you need, from payload and tongue weight to GVWR and combined vehicle weight.
Checking the whole combination?
Use the full Tow Calculator to compare entered vehicle, trailer and hitch limits and identify the closest available rating.
Vehicle limits
Payload checks added loads; GVWR checks the vehicle’s loaded total; GCWR checks the vehicle and trailer together. These ratings are not interchangeable.
GCWR Calculator
You want to check the combined weight of your trip-ready vehicle and loaded trailer.
GVWR Calculator
You want to compare the weight carried by the vehicle itself with its GVWR.
Trailer weights
Build a loaded trailer estimate first if needed. Tongue and pin tools estimate the portion carried at the hitch—not an official tow rating.
Tongue Weight Calculator
You have loaded trailer weight and want to estimate the portion carried at the hitch.
Trailer Weight Calculator
You know dry/UVW weight and need a loaded estimate that includes trip additions.
Fifth-Wheel Pin Weight Calculator
You need a fifth-wheel pin-load estimate or want to express known pin load as a percentage.
Setup
Brake gain requires your controller’s documented procedure. This checklist helps organize preparation without guessing a setting.
Trailer Brake Gain Guide & Adjustment Tool
You need a checklist for a controller’s documented adjustment process, not a guessed gain number.
