Use this reliable calculator to determine the maximum safe trailer weight your Ford truck can tow, based on its Gross Combined Weight Rating (GCWR) and your actual vehicle load. Safety is paramount when towing, and exceeding your truck's limits can be dangerous.
Ford Maximum Towing Capacity Calculator
Calculation Steps
Ford Towing Capacity Formula
The calculation is based on the truck's Gross Combined Weight Rating (GCWR) — the maximum safe total weight of the truck, cargo, passengers, and the fully loaded trailer.
Formula Sources: Edmunds Towing Guide SAE J2807 Towing Standard
Variables
A clear explanation of the inputs required for the calculator:
- Gross Combined Weight Rating (GCWR): This is the maximum weight of the loaded truck (GVW) plus the loaded trailer, as specified by the manufacturer. This number is your hard limit.
- Truck Curb Weight: The actual weight of your truck when empty (full fluids, but no passengers or cargo).
- Cargo and Passenger Weight: The total weight of all passengers, gear, accessories, and anything else loaded *into* the truck bed or cab.

What is Ford Towing Capacity?
Towing capacity is the maximum weight a vehicle is rated to tow safely. For Ford trucks, this figure is typically determined by adhering to the SAE J2807 standard, which provides a consistent method for calculating and rating a vehicle's towing ability across different manufacturers. This calculation takes into account engine performance, cooling capacity, structural integrity, and braking capabilities.
The most restrictive factor is often the GCWR, which ensures that even on steep grades or emergency braking situations, the entire combined weight does not overwhelm the truck’s core systems. Always consult your specific Ford model’s owner's manual or the sticker on the driver's side door jamb for the exact GCWR and GVWR ratings.
How to Calculate Towing Capacity (Example)
- Identify GCWR: A Ford F-150 has a GCWR of 18,000 lbs.
- Determine Truck Total Weight: The truck's curb weight is 5,500 lbs, and you load 800 lbs of passengers and gear. Truck Total Weight = 5,500 + 800 = 6,300 lbs.
- Calculate MSTW: Subtract the Truck Total Weight from the GCWR. MSTW = 18,000 lbs - 6,300 lbs.
- Final Result: The Maximum Safe Trailer Weight is 11,700 lbs.
Frequently Asked Questions (FAQ)
Trailer tongue weight (the downward force on the hitch) should generally be between 10% and 15% of the total loaded trailer weight. This is critical for stable, safe towing.
GVWR (Gross Vehicle Weight Rating) is the maximum weight the truck itself can hold (including passengers, cargo, and tongue weight). GCWR (Gross Combined Weight Rating) is the maximum total weight of the truck *and* the trailer combined.
Your GCWR is usually printed on a decal located on the driver's side door jamb, in the owner's manual, or on the trailer hitch itself (though the hitch rating may be lower than the truck's overall rating).
No. This calculator provides a theoretical maximum based on manufacturer ratings. Always verify your actual vehicle and trailer weights on a scale and ensure proper loading, tire pressure, and brake functionality.
