About this truck payload calculator
Payload is everything the tow vehicle carries. When towing, that includes the downward load from the trailer in addition to people, tools, coolers, cargo and hitch hardware.
How the calculation works
- Start with the payload rating for your exact vehicle.
- Add passengers, cargo and hitch hardware.
- Enter measured tongue/pin weight or let the calculator estimate it from trailer weight and percentage.
- The result shows payload used, payload remaining and utilization percentage.
Get a better result
- The yellow tire/loading label is usually the best place to start for vehicle-specific payload.
- Aftermarket accessories can reduce remaining payload.
- Use actual scale weights for the most reliable planning.
Important: Tow Capacity Lab provides planning math, not a certification that a combination is safe, legal or manufacturer-approved. The lowest applicable rating always controls.
Frequently asked questions
Does tongue weight count against payload?
Yes. The portion of trailer weight carried by the hitch is supported by the tow vehicle and contributes to payload use.
Is curb weight the same as payload?
No. Curb weight is the vehicle's own weight under a defined condition. Payload is the allowable weight added to the vehicle, subject to its ratings.
