Amazon Head Shipping Costs: How to Calculate and Choose the Best Transport Method

If you’re an Amazon seller, understanding head shipping costs and transport options is crucial for managing your business expenses. This guide explains how to calculate Amazon FBA freight fees and compares air, sea, rail, and truck transportation methods.

What Are Amazon Head Shipping Costs?

Head shipping costs refer to expenses for moving inventory from your location to Amazon’s fulfillment centers. These fees cover transportation, customs duties, and handling charges. Proper calculation helps avoid unexpected costs that eat into profits. According to a 2024 FBA fee analysis, shipping represents 18-34% of sellers’ operational budgets.

How to Calculate Amazon Head Shipping Costs (Step-by-Step)

1. Measure Package Dimensions

Amazon uses dimensional weight (DIM weight) to calculate costs. Measure length, width, and height in inches. Multiply them and divide by 139 to get DIM weight. Example:

• Package size: 18″ x 12″ x 10″
• DIM weight: (18×12×10)/139 = 15.5 lbs

2. Weigh Your Shipment

Use calibrated scales to determine actual weight. Amazon charges based on whichever is higher: actual weight or DIM weight. A shipping optimization study shows 62% of sellers overpay due to incorrect measurements.

3. Select Shipping Method

Choose between four main options:

• Air transport: 3-7 days
• Sea freight: 20-45 days
• Rail shipping: 18-25 days
• Truck delivery: 2-5 days (domestic)

4. Calculate Final Costs

Use Amazon’s FBA revenue calculator with these inputs:

• Product dimensions
• Transportation method
• Destination fulfillment center
• Customs fees (for international)
