Trailer Weight & Towing Calc

Trailer Weight Calculator does the towing math for you, so you know your rig is safe and legal before you pull out of the driveway. Enter your numbers and get tongue weight, payload, and total trailer weight in seconds, with every result kept right on your phone.

Overloading a trailer is dangerous. It can fail a weigh station, earn a ticket, and void your insurance. This trailer weight calculator checks the numbers that keep you under your limits, whether you tow a travel trailer, a camper, a boat trailer, a car hauler, a utility trailer, or a fifth wheel.

What you can calculate
Tongue weight and tongue weight percentage (nose weight in Australia and the UK), the 10 to 15 percent range that keeps a trailer from swaying.
Payload and remaining payload against your truck door sticker.
Total trailer weight, loaded and unloaded.
GVWR, GAWR, and GCWR, and how much towing capacity you have left.
Weight distribution across the axles, so you can load the trailer the right way.
CAT scale ticket math, so you can turn a weigh station slip into axle weights that actually make sense.

Save your trucks and trailers
Store each truck and trailer as a profile with its GVWR, curb weight, and axle ratings, then reuse it every trip. No re-typing the same sticker numbers before every haul. Switch between your daily driver and your tow rig in one tap.

Pre-trip towing checklist
Run a quick weight and hitch check before you leave, so nothing gets missed on a busy morning at the campground or the boat ramp. Confirm tongue weight, payload, and hitch setup before you roll.

Why this towing calculator
Fast and simple, built to do one job at the trailer, gloves on, with no signup and no account.
Your trailer and truck numbers never leave your device.
Clear results with the safe ranges shown, not just raw numbers.
Made for real towing, using the same GVWR, GCWR, GAWR, and payload terms you already see on your door sticker and in your owner manual.
No ads crammed next to the buttons, so you never fat-finger the wrong number.
An internet connection is required.

Who it is for
RV and travel trailer owners, campers, boaters, horse and livestock haulers, car and equipment trailer users, landscapers, and anyone who wants to tow within their limits and skip the guesswork. If you have ever wondered whether your trailer is overloaded or your tongue weight is right, this tool answers it in seconds.

Understand your numbers
Tongue weight too low and the trailer can sway. Too high and you overload the rear axle. Payload over the limit and you are illegal and unsafe. This calculator shows you where you stand against every rating, so you can adjust the load before you hit the road, not after a weigh station stop.
