Master Your Logistics Budget Using Spreadsheet Formulas for Accurate Cost Forecasting

The Budgeting Challenge in Global Sourcing

For importers and e-commerce businesses, one of the most unpredictable costs is often international freight. Unexpected shipping fees can devastate a product's profit margin. Traditional quoting methods are slow and reactive, making advance budgeting a guessing game. This is where the strategic use of a GTBuy Freight Estimation Spreadsheet

Core Concept: The Weight-Based Estimation Formula

Freight forwarders primarily calculate costs using Chargeable Weight, which is the greater of the actual gross weight or the volumetric weight. By integrating this calculation into a spreadsheet, you can generate instant estimates.

Key Formulas for Your Spreadsheet

The volumetric weight formula is standardized:

= (Length * Width * Height) / DIM Divisor

Where the DIM Divisor

The critical logic for chargeable weight becomes:

= MAX(Actual_Weight, Volumetric_Weight)

This core calculation feeds directly into your cost forecast.

Building Your Forecasting Model

A robust GTBuy estimation sheet connects product data, logistics rules, and rate cards.
