How to use this calculator

  1. Enter realistic vehicle, fuel, tire, payload, service, or shop values.
  2. Check the unit labels before calculating.
  3. Click Calculate to update the result.
  4. Round conservatively for safety, towing, fuel range, wear, and equipment capacity.

Formula or calculation method

Tongue weight = loaded trailer weight x tongue weight percentage.

Payload remaining = vehicle payload rating - people/cargo - tongue weight.

Worked example

A 5,500 lb trailer at 12% tongue weight places about 660 lb on the hitch before passengers and cargo.

Practical planning tips

  • Use actual vehicle placards, ratings, scales, and inspection measurements.
  • Round conservatively where safety margins matter.
  • Get qualified service help when wear, warning lights, handling, towing, or tire condition is uncertain.

Common mistakes to avoid

  • Mixing units.
  • Using ideal ratings instead of real-world values.
  • Skipping reserve for safety, weather, load, and wear.
FAQ

Tongue Weight Calculator questions

Is this calculator exact?

No. It is a planning estimate. Vehicle condition, tires, load, terrain, driving style, shop pricing, electricity rates, and manufacturer ratings can change the result.

Should I add a reserve?

Yes. Add reserve for towing, fuel stops, tire pressure, payload, brake wear, compressor output, and trip planning.

Does this replace manufacturer or professional guidance?

No. Verify important decisions with owner manuals, tire placards, load charts, service manuals, scale weights, and qualified repair professionals.
