ContainerMath review
A capable web load planner for teams managing mixed freight and commercial documents.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
ContainerMath is web-based load-planning software for manufacturers, exporters, logistics teams, freight forwarders, 3PLs and distributors. It calculates carton and crate placement across shipping containers, trailers, rail equipment and air ULDs, with both 3D and 2D visualizations. Teams can import manifests, review weight distribution and axle loads, sequence deliveries, save plans, and export reports or shipment documents. Its scope suits operations that need more than a basic container layout, particularly when mixed fleets, commercial documents and repeatable planning workflows are part of the process.
The pricing structure starts with a Free Trial that requires no credit card and includes interactive 3D and 2D plans for all 50 road, rail and sea vessel types. Starter costs $39.99 per seat per month or $384 per seat per year, with 50 calculations per month, AI and spreadsheet manifest import, and clean image exports. Pro Plus costs $129 per seat per month or $1,238 per seat per year. It adds unlimited calculations subject to a fair-use cap, saved load plans, equipment libraries, API access, webhooks and document exports. Custom adds white-label exports, unlimited API access, enterprise SSO on request, onboarding and dedicated support.
ContainerMath’s strongest fit is with teams connecting planning to broader logistics or business systems. Its REST API and ERP/TMS webhooks support workflows involving SAP, NetSuite, TMS, CRM, ERP and WMS platforms, while Claude and ChatGPT are listed alongside its AI import capabilities. Export formats include PDF, CSV/XLSX and images, and the product also supports commercial invoices and packing lists. Teams needing frequent calculations, saved libraries or system integration should consider Pro Plus or Custom; smaller operations with occasional loads may find Starter’s monthly calculation limit restrictive, while organizations requiring a free ongoing plan should choose an alternative.
