Towing calculators

Every tool runs in your browser, uses the same conservative math, and works from the numbers on your door-jamb sticker. Start with the tow-match calculator, then check tongue weight and payload.

• Tow-Match Calculator Your honest max trailer with the limiting factor named — tow rating, GCWR, payload, or hitch.
• What Can I Tow? (reverse) Start from the trailer: what a tow vehicle needs to pull it — then check a specific one.
• Tongue Weight Calculator The right 10–15% tongue weight, and a check for whether yours is in the safe range.
• Payload Calculator What your truck can actually carry — and how much of it the tongue weight eats.
• GVWR & GCWR Calculator Turn the sticker numbers into real limits: payload and the combined-weight trailer max.
• Weight-Distribution Hitch Do you need a WDH — and does your receiver need one to reach its full rating.
• Trailer Weight Estimator Estimate loaded trailer weight from dry weight, cargo, water, propane, and batteries.

New to the terminology? The towing guides explain GVWR, GCWR, tongue weight, and hitch classes in plain English — and every number on this site follows the methodology.
