What to check before booking

The result is a planning estimate, not a freight quote or load-safety approval. Measure the finished package, confirm the correct carrier service and divisor, and apply the rounding method in your current contract. For pallets and containers, also verify maximum payload, door clearance, stacking strength, load restraint, and local transport rules.

Equipment specifications and tariff rules can change. Cargoivo keeps common presets visible while letting the carrier's own documentation remain the final authority.

Calculator behavior is checked with repeatable examples documented in How We Test and the Cargoivo Lab.
