Pro rata freight

3 key takeaways

• Pro rata freight calculates shipping costs based on the proportionate share of the cargo’s characteristics.
• This method ensures that each shipment is charged fairly according to its specific attributes.
• It is commonly used in logistics and shipping to allocate costs accurately among multiple shippers.

What is pro rata freight?

Pro rata freight is a method used to determine the freight charges for a shipment based on its proportional share of the total cargo being transported.

This calculation can be based on factors such as weight, volume, or value. The term “pro rata” means “in proportion,” ensuring that each shipment is charged fairly according to its contribution to the overall load.

How is pro rata freight calculated?

Pro rata freight charges are calculated by dividing the total freight cost among the shipments based on their specific characteristics. Here’s how it typically works:

1. Determine the Basis for Calculation: Decide whether the charges will be based on weight, volume, or value.
2. Calculate Proportionate Share: Determine each shipment’s proportionate share of the total cargo. For example, if using weight:
   • Proportionate Share = Weight of Individual Shipment / Total Weight of All Shipments
3. Apply the Proportionate Share to Total Freight Cost: Multiply the total freight cost by the proportionate share to find the pro rata freight charge for each shipment.

Example of pro rata freight calculation

Imagine a shipping company is transporting three shipments with a total freight cost of $600. The shipments have the following weights:

• Shipment A: 200 kg
• Shipment B: 300 kg
• Shipment C: 500 kg

The total weight of all shipments is 1000 kg. The pro rata freight charge for each shipment is calculated as follows:

1. Shipment A:

   • Proportionate Share = 200 kg / 1000 kg = 0.2
   • Pro Rata Freight Charge = 0.2 * $600 = $120

2. Shipment B:

   • Proportionate Share = 300 kg / 1000 kg = 0.3
   • Pro Rata Freight Charge = 0.3 * $600 = $180

3. Shipment C:

   • Proportionate Share = 500 kg / 1000 kg = 0.5
   • Pro Rata Freight Charge = 0.5 * $600 = $300

Importance of pro rata freight

Pro rata freight is important for several reasons:

• Fair Distribution of Costs: It ensures that each shipper pays a fair share of the total freight cost based on the specific attributes of their shipment.
• Cost Efficiency: By accurately allocating costs, it helps in managing and optimizing shipping expenses.
• Transparency: Provides a clear and justifiable method for determining freight charges, fostering trust and clarity between shippers and carriers.

Pro rata freight is a practical approach in logistics and shipping, ensuring equitable cost distribution based on the characteristics of each shipment.
