This calculator will help you understand and calculate the various weights involved when you tow; for example how much payload you have left, whether a towcar can tow a trailer, how close you are to limits such as GCM.
The calculator assumes you are familiar with terms like GVM, GCM and TBM. If you’re not, then please read this first, then come back here.
If you are familiar with towing weights, then here’s some explanatory notes about the calculator.
Calculator results are for guidance only – final checks should be made using all the data and limitations specific to your towcar and trailer which this calculator may not cater for.
The calculator and the information provided is free to you but cost me to produce and maintain, so please consider supporting me on Patreon and YouTube. Sponsorship welcome so long as independence is maintained.
