Introduction

This Ford Towing Calculator shows how much your Ford truck or SUV can safely pull. Pick your model year, model, engine, cab, wheelbase or box, drivetrain, and axle ratio. Then add your passengers, cargo, and trailer weight. The tool works out the numbers for you.

You get four key checks in one place: max tow rating, payload and GVWR, tongue or pin weight, and GCWR. Each check shows a clear OK, Caution, or Exceeds label, so you know right away if your load is safe.

The calculator also tells you which hitch class you need, whether your state's law requires trailer brakes, and how much Ford says to cut your weights at high altitude. You can switch between pounds and kilograms, and compare two Ford models side by side with the same trailer.

It covers Ford F-150, F-150 Lightning, Super Duty F-250 through F-550, Ranger, Maverick, Expedition, Explorer, Bronco, Edge, Transit, and Transit Connect from 2004 to 2026, using the rating Ford lists for each exact configuration. Always double-check the numbers against the door jamb sticker and your Ford Owner's Manual before you tow.

How to use our Ford Towing Capacity Calculator

Pick your Ford truck or SUV, then tell us what you are hauling. The calculator shows your max tow rating, payload left, tongue weight, GCWR check, hitch class, brake rules, and a step-by-step math breakdown.

Weight Units: Choose pounds or kilograms. All numbers switch over for you.

Highest Elevation on the Trip: Pick the highest elevation you will tow at, and the calculator lowers GCWR and GVWR by Ford's high-altitude reduction.

Your State: Pick where you drive. This sets the trailer weight at which brakes are required by law.

Comparison Mode: Turn this on to check a second Ford side by side with the same load.

Model Year: Pick the year of your Ford, from 2004 to 2026. Each model year uses the RV & Trailer Towing Guide Ford published for that year.646566676869707172737445678910111213141

Vehicle Model: Pick your Ford, like F-150, F-250 Super Duty, Ranger, Maverick, or Expedition.

Cab / Body Style: Pick your cab, such as Regular Cab, SuperCab, SuperCrew, or Crew Cab.

Wheelbase / Box / Version: Pick the wheelbase, box length, single or dual rear wheels, or version that Ford lists for your cab.

Engine / Powertrain: Pick your engine. The list shows only the engines Ford rated for that model year.

Drivetrain: Pick the drivetrain as Ford lists it, such as 4x2, 4x4, RWD, FWD, AWD, or 4WD.

Rear Axle Ratio & GCWR: Pick your axle ratio and the gross combined weight rating Ford lists with it. The ratio is on the door sticker. Some axles list more than one GCWR; pick the one that matches your truck's equipment.

Rating Listed: When Ford prints more than one rating for the same setup, such as a weight-carrying and a weight-distributing hitch, a 5th-wheel and a gooseneck rating, or a rating that needs a package or tire size, pick the one that matches your truck. The notes under the vehicle list what each rating needs.

GVWR and Curb Weight: Enter the GVWR from the Safety Compliance Certification Label and your truck's curb weight to check payload and GCWR.

Vehicle B fields: Fill these the same way to compare a second truck.

Number of Passengers: Enter how many people ride, including the driver (1 to 8).

Average Weight per Passenger: Enter the average weight of each person. Default is 150 lb.

Cargo / Gear in Vehicle: Enter the weight of tools, bags, coolers, and add-ons in the cab, bed, or roof.

Trailer Type: Pick your trailer, such as travel trailer, boat, horse trailer, car hauler, 5th wheel, or gooseneck.

Trailer Gross Weight: Enter the loaded trailer weight, not the empty or dry weight.

Tongue / Pin Weight Method: Choose Auto-Calculate to use a percent, or Manual Entry to type a scale reading.

Estimated Tongue / Pin Weight %: Pick the percent for your trailer type. Bumper pulls run 10–15%. Ford rates fifth wheels and goosenecks at 15%.1

Tongue Weight: This fills in on its own in auto mode. In manual mode, type your real scaled weight.

Press Calculate to see your results, or Reset to start over.

Ford Towing Capacity: What It Means

Every Ford truck, SUV, and van has a limit on how much weight it can safely pull. That limit is called towing capacity. It is set by Ford after testing the brakes, frame, engine, cooling system, and axles. Going over the limit can wear out parts fast, make stopping harder, and even void your warranty.

The Four Numbers That Matter

  • Max Tow Rating – the heaviest trailer your Ford can pull.
  • GVWR (Gross Vehicle Weight Rating) – the most your truck can weigh with people, gear, and the trailer's tongue pushing down on it.1
  • Payload – GVWR minus curb weight.1 This is the weight you are allowed to add. Tongue weight counts against it, which surprises many people.1
  • GCWR (Gross Combined Weight Rating) – the most your truck and trailer can weigh together.1

You must stay under all four. Most people run out of payload long before they run out of tow rating.

Tongue Weight and Pin Weight

Tongue weight is the part of the trailer's weight that presses down on the trailer hitch.1 Ford's guide says a conventional trailer over 2,000 lb should put 10% of its loaded weight on the tongue, and a trailer up to 2,000 lb no more than 200 lb.1 The calculator flags a tongue weight below 10% or above 15%. Too little tongue weight can cause instability, which may result in tail wagging or jackknifing.1 Too much can press the back of the truck down until the front wheels lift, which hurts traction, steering and braking.1

A 5th wheel or gooseneck trailer connects in the truck bed instead. The weight on that connection is called king pin weight, and Ford's guide sets it at 15% of the loaded trailer weight for 5th-wheel trailers.1

What Changes Your Ford's Rating

Two F-150s parked side by side can have very different tow numbers. These things change it:

  • Engine – a 3.5L EcoBoost or 6.7L Power Stroke diesel pulls far more than a base V6.
  • Max Trailer Tow Package – adds better cooling, a stronger hitch, wiring, and often a brake controller. It can add thousands of pounds.
  • Rear axle ratio – a numerically higher ratio like 3.73 tows more than 3.15.
  • Cab, bed, and 4WD – bigger cabs and 4WD add weight, which eats into payload and tow rating.
  • Trim level – fancy trims are heavier, so they tow a bit less.

Tires and wheels matter too. Load-range and diameter changes shift your effective gearing and speedometer reading, so check the Tire Size Calculator before you tow on a new setup.

Trailer Classes

ClassGross Trailer Weight
I (light-duty)Up to 2,000 lb1
II (medium-duty)2,001 to 3,500 lb1
III (heavy-duty)3,501 to 5,000 lb1
IV (extra-heavy-duty)Over 5,000 lb1

Heavy trailers also need a weight-distributing hitch, and Ford's F-150 charts say not to exceed 5,000 lb of trailer weight without one.1 This spreads the load across all axles instead of squatting the rear. When you bolt on a hitch or ball mount, torque every fastener to spec.

Trailer Brakes and the Law

Many states require a separate braking system on trailers with a loaded weight of more than 1,500 pounds, and Ford recommends a separate working brake system on any towed vehicle.1 The rules vary a lot. New York requires brakes on trailers that weigh more than one thousand pounds empty, and on newer trailers whose gross weight is over three thousand pounds.3 Michigan requires brakes on all wheels of a trailer with a gross weight of 15,001 pounds or more, and new trailers of 3,000 pounds or more sold in the state need brakes unless the trailer is no more than 40% of the towing vehicle's weight.2 Check your own state, and add a brake controller if you need one. Ford's tow package usually includes an integrated one.

Hills, Heat, and Real-World Towing

Ford's numbers come from ideal test conditions. At high altitude, Ford says to reduce gross vehicle weight and gross combination weight by 2% per 1,000 ft of elevation to match sea-level performance.1 Pick your highest elevation and the calculator applies that reduction to GCWR, and to GVWR when you enter it. Heat, wind, and a tall boxy travel trailer all make the job harder. Use Tow/Haul mode on grades, and never trust a trailer's "dry weight" sticker. Load it up, drive to a truck scale, and weigh it for real.

Towing also raises your running costs. Fuel economy drops with a big trailer behind you, so budget the trip with our Gas Mileage Calculator. Add stops and slower speeds into your schedule.

Buying the Right Tow Vehicle

If this calculator shows your trailer is too heavy, the fix is usually a bigger truck or a lighter trailer.

Frequently asked questions

Why does my truck run out of payload before it hits the tow rating?

Because tongue weight lands on your truck, not the trailer. A 7,500 lb trailer at 12% puts 900 lb on the hitch. Add four people at 150 lb each (600 lb) and 300 lb of gear, and you have already used 1,800 lb of payload. A half-ton truck's payload is often smaller than people expect, so check the sticker. That is why the payload check often fails first, even when the tow rating looks fine.

Where do I find my real payload number?

Look at the yellow sticker inside your driver's door jamb. It says "The combined weight of occupants and cargo should never exceed XXX lb." That number is for your exact truck, with the options it left the factory with. Enter your truck's GVWR and curb weight in the calculator to check your load against it.

How do I find my rear axle ratio?

Check the door jamb sticker for a code in the axle box, or look at the window sticker if you still have it. Common Ford codes are 19 (3.31), 26 (3.55), and 27 (3.73). A Ford dealer can also look it up from your VIN.

How do I know if I have the Max Trailer Tow Package?

Look for these clues: a 4-pin and 7-pin trailer plug, an integrated trailer brake controller in the dash, trailer tow mirrors, an upgraded rear axle, and a higher-capacity hitch receiver. If you are not sure, give your VIN to a Ford dealer. Ford ties many of the higher ratings to the package, and the calculator names it in the note under those ratings.

Should I use dry weight or loaded weight for my trailer?

Always loaded weight (GVW). Dry weight leaves out water, propane, batteries, food, bikes, and gear. A packed travel trailer can weigh far more than its dry weight. If you do not know the loaded weight, use the trailer's GVWR from its own sticker to stay safe.

What is the difference between Auto-Calculate and Manual Entry for tongue weight?

Auto-Calculate multiplies your trailer weight by a percent, which is a good estimate. Manual Entry is for when you have weighed the tongue on a scale or with a tongue weight gauge. Real scale numbers beat estimates every time, so use Manual Entry if you have them.

Why did my max tow number drop when I picked a 5th wheel?

On Super Duty trucks the 5th wheel rating is usually higher than the conventional one. On a 2026 F-150 it is lower: Ford rates the 5.0L V8 at up to 12,800 lb on a conventional hitch and 11,700 lb on a 5th wheel or gooseneck.1 When Ford prints no 5th wheel or gooseneck rating for a configuration, the calculator says so instead of showing a number.

Where do the ratings come from?

Each rating is the one Ford lists for that exact configuration in the RV & Trailer Towing Guide for that model year, from 2004 to 2026. The lists only offer combinations Ford rated. Confirm the figure with your Owner's Manual before you tow.

My tongue weight percent shows a warning. What do I fix?

If it is under 10%, move cargo forward, ahead of the trailer axles. Low tongue weight causes sway.1 If it is over 15%, move cargo back a bit so you do not lift the front tires and lose steering feel. Small shifts of 100 to 200 lb can move the percent a lot.

Do I need trailer brakes if my state does not require them?

Ford recommends a separate working brake system on any towed vehicle, and many states require one on trailers over 1,500 lb loaded.1 Trailer brakes cut your stopping distance a lot and reduce sway. Most Ford tow packages include an integrated brake controller, so you just wire the trailer.

What is a weight-distributing hitch and do I need one?

It uses spring bars to spread tongue weight across the truck's front axle and the trailer axles instead of squatting the rear. The calculator suggests one when your tongue weight tops about 500 lb or your trailer tops about 5,000 lb. Most travel trailers need one, and many hitch ratings require it.

What does GCWR mean and why does it matter?

GCWR is the most your truck and trailer can weigh together. Even if the trailer is under the tow rating, a heavy load of people and gear can push the combined weight over GCWR. That is the rating that protects your engine, transmission, and brakes, so the calculator checks it separately.

How does comparison mode help me?

It runs the same trailer, passengers, and cargo through two Fords at once. You see which truck has more tow rating, more payload left, and more GCWR margin. It is the fastest way to answer questions like "Do I really need a Super Duty, or will an F-150 do the job?"

Can I switch to kilograms without retyping everything?

Yes. Change the Weight Units dropdown and every input and result converts for you. Your passenger, cargo, trailer, and tongue numbers are rewritten in the new unit automatically.

Why is my SuperCrew 4WD rated lower than a Regular Cab 2WD with the same engine?

Bigger cabs and 4WD hardware add several hundred pounds. That extra truck weight counts against both GCWR and payload, so the tow rating drops and you have less room for people and gear.

How do I weigh my trailer and tongue weight for real?

Drive to a public truck scale (many truck stops have one). Weigh the loaded truck and trailer together, then unhook and weigh just the trailer. For tongue weight, weigh the truck hooked up and again unhooked; the rear axle gain is close to your tongue weight. A tongue weight scale is easier for lighter trailers.

Does going over the tow rating void my Ford warranty?

It can. Ford can deny claims on parts that failed because of overloading, like the transmission, rear axle, brakes, or frame. Beyond warranty, overloading raises crash risk and can bring tickets or liability after a wreck. Stay under every rating.
