Trailer Payload Calculator
Estimate usable trailer payload from GVWR, empty weight, and tongue weight for equipment hauling.
Common questions
- What is trailer payload capacity?
- Payload is GVWR minus empty trailer weight. It's the total cargo weight the trailer is rated to carry, including tongue-transferred weight.
- How do I find my trailer's GVWR?
- It's stamped on the VIN sticker, usually on the driver-side front tongue or frame rail. Never estimate — the sticker is the legal max.
- What tongue weight percent is safe?
- 10–15% of loaded trailer weight is the standard safe range. Below 10% causes sway; above 15% strains the tow vehicle's rear axle.
- Can I exceed GVWR briefly?
- No — insurance, brakes, and axles are all rated to GVWR. Any overload voids warranty coverage and increases liability in an accident.
