Calculators
Calculators for the Federal Bridge Formula, the axle weights of a tractor-semitrailer and the number of pallets a vehicle can carry. Each applies the same limits and calculations as the load planner, and each is free to use without an account.
The results are intended for planning. They apply the federal limits on the Interstate System in the United States and Directive 96/53/EC in the European Union, and the weights recorded on a certified scale are authoritative.
- Bridge Formula CalculatorCalculate the maximum weight on every group of axles under the Federal Bridge Formula, and check axle weights against the federal limits on the Interstate System.
- Axle Weight CalculatorCalculate the steer, drive and trailer axle weights of a tractor-semitrailer from the position of its cargo, and check each against the federal limits.
- Pallet CalculatorCalculate how many pallets fit in a trailer or truck, and how many can be carried within United States or European Union weight limits.
