Towing Capacity Check

The Towing Capacity Check substitutes your inputs (GCWR (kg), Curb weight (kg), Cargo + passengers (kg), Trailer weight (kg)) into the standard expression: Max trailer (kg) = GCWR (kg) − Curb weight (kg) − Cargo + passengers (kg); Remaining margin (kg) = GCWR (kg) − Curb weight (kg) − Cargo + passengers (kg) − Trailer weight (kg). Every variable is read straight from the fields on this page, and the result is computed the moment you enter the values.

1. 1

   Step 1

   Enter the vehicle data and required values.

2. 2

   Step 2

   Then press "Calculate" to get the result.

3. 3

   Step 3

   You can re-run the calculation with different values anytime.

4. 4

   Step 4

   The breakdown lists your inputs — GCWR (kg), Curb weight (kg) next to the computed value under the page's standard expression; read it before relying on the number.

5. 5

   Step 5

   Adjust one input at a time and compare scenarios: change GCWR (kg) and re-run to see which variable moves the towing capacity check result most.

• 1

  The Towing Capacity Check needs every variable in consistent units — GCWR (kg), Curb weight (kg) — before the standard formula returns a valid result, so check each field's unit before entering values copied from elsewhere.

• 2

  Round only at the end: Towing Capacity Check carries full precision internally, so rounding intermediate values by hand can shift the final answer more than the accuracy of the formula itself ever would.

• 3

  Copy the Towing Capacity Check result together with the input values that produced it; a number without its documented inputs cannot be re-verified later, and assumptions are easy to forget once the session is closed.

• Zero and negatives can sit outside the formula's domain: zero curb weight (kg) may make the Towing Capacity Check undefined, and a negative gcwr (kg) still returns a number. Check each input is inside the range the quantity allows.

• Percentage conventions differ by field: some Towing Capacity Check inputs expect curb weight (kg) as a whole number (5 for 5%), others as a decimal (0.05). The two forms are off by ×100 — match the field's label or example.
