Freight Planning Calculators for Ocean & Air Shipping
Free browser-based tools to calculate cargo volume, estimate container loading capacities, and compare freight quotes. All calculations are planning estimates based on transparent formulas and your entered data—with no logins, paywalls, or hidden assumptions.
Choose the Right Freight Tool
Select the calculator matching your current shipping decision stage.
CBM Calculator
Use when calculating total cubic volume from box dimensions, converting between metric and imperial units, or evaluating billable chargeable weight for ocean, air, and express courier quotes.
Container Loading Calculator
Use when estimating how many uniform cartons can realistically fit inside 20GP, 40GP, or 40HC ocean containers based on 3D orthogonal packing orientations and payload limits.
LCL vs FCL Calculator
Use when you already have ocean freight quotes and need to evaluate whether LCL consolidation or a dedicated container is more economical for your shipment, and find the cost crossover volume.
Interactive Planning Calculators
Browser-based tools running client-side with no server data collection.
CBM Calculator
Calculate cubic meters, cubic feet, and volumetric/chargeable weights for air and ocean freight.
Container Loading Calculator
Estimate carton capacity and payload utilization for 20GP, 40GP, and 40HC shipping containers.
LCL vs FCL Calculator
Compare freight quotation costs and estimate break-even volume between LCL and FCL containers.
