Tow Weight Calculator

Tow with confidence. Travel with safety.

Understanding your vehicle and caravan weights is essential for safe and legal towing. Our RV Weight Calculator is a simple yet powerful tool designed to help you determine whether your towing setup complies with manufacturer specifications.

What It Does:

By entering your vehicle’s Kerb Weight, Vehicle Payload, Towing Capacity, Tow Ball Mass, and your caravan’s ATM, the calculator automatically computes:

• GVM (Gross Vehicle Mass) – the total weight of your loaded vehicle.

• GCM (Gross Combination Mass) – the combined weight of your loaded vehicle and caravan.

Why It Matters:

Exceeding your GVM or GCM can affect your vehicle’s handling, braking, insurance, and warranty—and most importantly, your safety on the road.

⚠️ Disclaimer: This weight calculator is for use as a guide only and is reliant on the accuracy of the information input by the user. Always refer to your vehicle and caravan manufacturer specifications for official limits.
