What is the Payload Calculator?
Check remaining payload capacity from GVWR, curb weight and load. Know what a trip or a vehicle really costs. These auto and travel calculators cover fuel, charging, depreciation and the true per-mile cost of driving for commuters and professional drivers.
How to use the Payload Calculator
- Enter your gvwr, your curb weight, your passengers & cargo, your trailer tongue weight.
- Results update automatically as you type; you can also press Calculate.
- Read the output: remaining payload, status.
- Use the 📊 chart to see the result visually, then copy or share it.
Formula and method
Worked example
With gvwr = 7,000 lb, curb weight = 5,200 lb, passengers & cargo = 900 lb, trailer tongue weight = 500 lb, the Payload Calculator returns remaining payload: 400 lb; status: Within rated payload.
Tips for better results
- Use your real-world fuel economy rather than the window sticker.
- Depreciation is often the largest hidden cost of owning a car.
- Gig drivers should track every mile — it changes net hourly pay dramatically.
