About TheCBMcalc
Welcome to TheCBMcalc, your trusted resource for accurate shipping and logistics calculations.
We understand that in the world of international trade, accurate volume calculation isn’t just a number—it’s profit. Whether you are an Amazon FBA seller sourcing from Alibaba, a freight forwarder planning container loads, or an individual shipping personal effects, efficient space planning is critical to reducing costs.
Our Mission
Our mission is to simplify complex logistics formulas into easy-to-use tools. We aim to help importers and exporters:
- Avoid Overcharges: By calculating volumetric weight instantly.
- Optimize Loads: By estimating exactly how many cartons fit in a 20ft or 40ft container.
- Save Time: By removing the need for manual math and spreadsheets.
Why Use Our Tool?
Unlike generic calculators, TheCBMcalc is built specifically for the 2025 logistics landscape. We account for standard air freight divisors (5000/6000) and provide real-world container utilization estimates, not just theoretical capacities.
We are committed to keeping this tool free and accessible to businesses worldwide.
