Payload Calculator

The number on the brochure isn't what you can actually haul. Start from your GVWR, take out the truck, the people, the gear and the trailer tongue, and see the payload you really have left.

Payload isn't what the ad says

Truck ads love a big "best-in-class payload" number. What they don't tell you is that the figure is for a stripped work truck with vinyl seats and no options. Add a crew cab, four-wheel drive, a sunroof, and the diesel, and your real payload can be a thousand pounds lighter than the headline. The only numbers that matter are on the sticker inside your own door jamb.

Payload = GVWR − curb weight. Everything you add — people, tools, a camper, a trailer's tongue weight — comes out of that number, not out of some separate allowance.

The tongue-weight trap

Here's what puts people over without realizing it: a trailer's tongue weight rides on the truck. A travel trailer with 900 pounds of tongue weight uses 900 pounds of your payload before you've packed a single cooler. That's why so many half-tons "rated to tow 11,000 pounds" are actually out of payload with a family and a loaded trailer — they run out of payload long before they run out of pulling power.

Weigh it, don't guess it

  • Find your real curb weight. The sticker and brochure are estimates. A truck stop scale ($12 or so) tells you what your truck actually weighs with your gear in it.
  • Count everything. Passengers, dog, toolbox, fifth-wheel hitch, firewood in the bed — it all counts.
  • Leave a cushion. Running right at GVWR stresses brakes, tires and suspension. Keeping 10 to 15 percent in reserve is easy on the truck and on you.
Running bigger tires too? Heavier wheels and tires shave a little from payload and change your gearing — check both with the tire size and gear ratio calculators.

Payload FAQ

How do I calculate my truck's payload?
Payload = GVWR − curb weight. To see what's actually left, also subtract passengers, accessories and any trailer tongue or pin weight, because they all ride on the truck.
Does tongue weight count against payload?
Yes. Tongue weight of a bumper-pull, or pin weight of a gooseneck or fifth wheel, sits on the truck and counts against payload just like cargo in the bed.
What's the difference between GVWR and curb weight?
GVWR is the most the truck is rated to weigh fully loaded. Curb weight is what it weighs empty with fuel and no people or cargo. The gap is your payload capacity.
