Free Tools for Freight Forwarders

Practical calculators for the numbers forwarders work out every day — free, no sign-up. The full operator toolkit, including the automated air-cargo advisor, lives inside the Zavin platform.

Air freight

Air Freight Chargeable Weight Calculator

Volumetric vs gross weight on the IATA 6000 factor, with a loadability and IATA-document check by cargo type.

Cost planning

CargoWise Value Pack Cost Calculator

Estimate your monthly CVP software cost from your own file counts — and the labor cost per file automation can recover.

Inside the platform: the operator toolkit

The free calculators above are standalone. Inside Zavin, the same kind of utilities run on your live shipment data — no re-typing, one source of truth:

Container load planning — cartons and pallets fitted to 20GP / 40HC from real shipment data
Air-cargo loadability — dimensions to chargeable weight, aircraft and ULD fit, IATA document advice per cargo type
Live exchange rates, unit converters, and freight calculators — inside the operator's workspace, not a browser tab
