USFANS Spreadsheet: Estimate Shipping Fees Before Checkout

2026-01-19

A key challenge for international shoppers is encountering unexpected shipping costs at checkout. With the USFANS spreadsheet method, you can now calculate estimated delivery fees in advance, ensuring transparency and avoiding financial surprises.

Why Pre-Estimate Shipping Costs?

Final checkout prices often differ from initial product prices due to:

  • Volumetric Weight:
  • Service Tiers:
  • Destination Zones:
  • Fuel Surcharges:

Estimating costs upfront helps with budget planning and comparing total costs across different agents or platforms.

The Core: Weight-Based Calculation Formulas

Most forwarders use a formula centered on the billable weight, which is the greater of the actual weight or volumetric weight.

1. Calculate Volumetric Weight

Volumetric Weight (kg) = (Length (cm) × Width (cm) × Height (cm)) ÷ Volumetric Divisor

Common divisors: 5000 for most international carriers, 6000 for some specific lines.

2. Determine Billable Weight

Billable Weight = MAX(Actual Weight (kg), Volumetric Weight (kg))

Carriers always charge based on this higher value.

3. Apply Shipping Rate

Estimated Cost = (Billable Weight (kg) × Rate per kg) + Base Handling Fee

Rates are specific to your chosen shipping line and destination country. They can be found on your forwarder's official price chart.
