How to calculate freight.

To calculate freight in the Australia domestic market with cents per kilo, basic charges and a minimum method, you should use the following formula:

Freight = (Weight (kg) x Rate (cents/kg)) + Basic Charge

There may be a minimum charge that must be met or exceeded, if that case you should use the maximum of the freight calculated using the formula above and the minimum Basic Charge. For example:

Freight = max((Weight (kg) x Rate (cents/kg)) + Basic Charge, Minimum Basic Charge)

This will ensure that the minimum Basic Charge is applied if the calculated freight is less than the minimum.

You can also consider using a freight calculator tool or contacting a freight company for a quote if you need to calculate freight for a specific consignment. The details of the freight calculation, such as the rate and basic charge, may vary depending on the company and the type of shipment as well as the origin and destination points.
