Use these formulas to calculate & further understand this jobsite mainstay

Time and again, Construction Business Owner is your source for understanding your gross vehicle weight ratio (GVWR). Below are simple formulas for your calculating your GVWR, as well as links to two popular articles on the subject from CBO.

This formula is considered the GVWR on some manufacturer’s trailers.

GAWR = sum of all tire capacities, or the sum of all axle capacities

GVWR = Trailer Capacity + Trailer Weight

Payload capacity can be determined by one of these two formulas:

1.       GVWR – Trailer Weight = Payload Capacity

2.       GVWR – Trailer Weight + Tongue Transfer = Payload Capacity
