What Is a Payload Calculator?
A Payload Calculator estimates how much weight a vehicle can carry based on its Gross Vehicle Weight Rating (GVWR) and curb weight. It can also compare that payload capacity with passengers, cargo, equipment and trailer hitch or tongue weight.
Payload is different from towing capacity. Payload generally refers to weight carried by the vehicle, while towing capacity refers to the weight of a trailer the vehicle is rated to tow.
How to Calculate Payload Capacity
Vehicle payload capacity can be calculated by subtracting the vehicle's curb weight from its GVWR.
Payload Capacity = GVWR − Curb Weight
For example, if a vehicle has a GVWR of 7,000 lb and a curb weight of 5,200 lb, its calculated payload capacity is 1,800 lb.
How Does the Payload Calculator Work?
The calculator first determines total payload capacity. It then adds the passenger, cargo, hitch and other weights you enter and subtracts that total from the available payload capacity.
Enter Vehicle Ratings
Enter the GVWR and curb weight for the vehicle being calculated.
Add Your Load
Add passengers, cargo, equipment, hitch weight and any other weight carried by the vehicle.
Check Remaining Payload
Review total capacity, used payload, percentage used and remaining payload.
Payload Calculation Example
Suppose a vehicle has a GVWR of 7,000 lb and curb weight of 5,200 lb.
Example
Now assume the vehicle carries 350 lb of passengers, 500 lb of cargo and 450 lb of trailer tongue weight.
What Counts Toward Vehicle Payload?
Payload can include more than cargo placed in the bed or trunk. Weight added to the vehicle may contribute to its total loaded weight.
Passengers
The combined weight of the driver and other occupants contributes to the load carried by the vehicle.
Cargo
Luggage, tools, supplies and other items carried in or on the vehicle add to its loaded weight.
Hitch or Tongue Weight
Trailer tongue or hitch load places weight on the tow vehicle and can reduce the payload available for other items.
Added Equipment
Accessories or equipment added to the vehicle may increase actual vehicle weight and reduce remaining payload.
What Is GVWR?
GVWR stands for Gross Vehicle Weight Rating. It is a manufacturer-specified maximum weight rating for the loaded vehicle. It is not the same as the vehicle's curb weight or towing capacity.
What Is Curb Weight?
Curb weight generally describes the weight of the vehicle in its standard operating configuration without the additional passenger and cargo loads being calculated. Definitions can vary, so use the appropriate specification for your vehicle.
Payload Capacity vs Towing Capacity
Payload capacity and towing capacity measure different things. Payload relates to weight carried by the vehicle, whereas towing capacity concerns trailer weight.
When towing, these limits can interact because trailer tongue or hitch weight places load on the tow vehicle.
Payload Capacity
Weight the vehicle can carry according to the applicable vehicle ratings and configuration.
Towing Capacity
Maximum trailer weight specified for a particular tow vehicle configuration under applicable conditions.
Why Payload Capacity Matters
Payload calculations help compare the weight added to a vehicle with the vehicle ratings entered into the calculator. This is useful when carrying passengers, hauling cargo or towing a trailer.
- Estimate remaining carrying capacity.
- Account for passenger weight.
- Include cargo and equipment.
- Include trailer tongue or hitch weight.
- Compare estimated loaded weight with GVWR.
This calculator provides mathematical estimates from the values you enter. Vehicle loading can also be limited by axle, tyre, wheel, hitch and other ratings. Use the manufacturer's information for your exact vehicle and equipment when determining actual loading limits.
Common Payload Calculation Mistakes
- Forgetting to include driver and passenger weight.
- Ignoring tools, luggage or accessories.
- Confusing payload capacity with towing capacity.
- Forgetting trailer tongue or hitch weight.
- Using specifications from a different vehicle configuration.
- Ignoring axle, tyre or other component ratings.
Payload Calculator FAQs
Subtract the vehicle's curb weight from its GVWR. The difference is the calculated payload capacity.
Passenger weight contributes to the load carried by the vehicle and should be considered when calculating available payload.
Trailer tongue or hitch load places weight on the tow vehicle and can reduce payload available for passengers and cargo.
No. Payload generally refers to weight carried by the vehicle, while towing capacity refers to trailer weight the vehicle is rated to tow.
Yes. Select kilograms from the calculator and enter all weight values in kilograms.
Check the vehicle's manufacturer information, certification label or owner's documentation for the applicable GVWR and other weight ratings.
