Free freight calculators and reference tools

Yes. Every calculator on this page runs without an account and without a trial. They exist because the calculations behind freight charges should not be a black box — a shipper who can reproduce a carrier's arithmetic is in a much better position than one who cannot.

The calculations are deterministic arithmetic performed for your session, not saved against an account. Where a tool needs a lookup — port codes, HS descriptions — that query goes to the relevant dataset or service. If you want a calculation retained as part of a shipment record with its source document and an export, use the workspace instead, where storage is explicit and deletable.

Use them as a transparent working calculation and verify against the governing tariff, service contract or operational requirement. Each tool states its own limits, because the arithmetic is only as right as the assumptions — the day-count convention, the divisor, the rounding rule and the rate basis are all contractual rather than universal.

The chargeable weight calculator for rating, the air waybill number checker for validating MAWB references, and the air cargo document checklist for working out what paperwork a shipment needs. The CBM calculator is useful for both modes, since volume feeds every volumetric calculation.

The container number checker for ISO 6346 validation, the container load calculator for equipment selection, the LCL freight calculator for weight-or-measure pricing, the demurrage and detention calculator for time-based charges, and the UN/LOCODE lookup for routing references.

Most calculators export a CSV audit of the calculation, including the inputs and the assumptions applied. That matters more than the answer: a dispute raised three weeks later is won by whoever can show their working, and a reconstructed argument from memory rarely recovers the difference.

Yes. They are built to be usable on a phone at a warehouse or terminal, which is frequently where the question comes up. The shipping mark generator also prints and saves to PDF directly from a mobile browser.

Each calculation has a guide explaining the method, the conventions and the mistakes that distort the result. The tool does the arithmetic; the guide tells you which arithmetic your contract actually calls for — which is usually the harder question.
