What this estimates
This tool estimates the all-in cost to move a bulk cargo on a single voyage: bunker fuel, port disbursements and vessel hire over the voyage days, divided by the cargo to give a cost per tonne. It's the number a shipper or trader wants when asking "what will it cost to get this cargo from A to B?" — built from independent inputs, not from any proprietary published freight rate.
How the cost is built
- Voyage days = sea days (distance ÷ speed) + load + discharge days.
- Bunker cost = fuel burn at speed × bunker price, plus port consumption.
- Hire cost = daily hire × voyage days.
- Total cost = bunkers + port disbursements + hire (+ canal). Cost per tonne = total ÷ cargo.
Example: cost to ship iron ore Brazil → China
A Capesize carrying ~171,000 t from Tubarão to Qingdao (~11,067 nm), with bunkers at $600/t and representative hire, comes out around $12 per tonne all-in, or roughly $2.0m for the voyage, over about 39 days. Because hire and bunker prices move daily, enter today's numbers to sharpen the estimate.
Common dry bulk routes
The calculator includes reference distances for major corridors — iron ore (Dampier/Tubarão → Qingdao), coal (Newcastle → Qingdao, Richards Bay → Rotterdam) and grain (US Gulf/Santos → Qingdao). For any other pair, type the distance in nautical miles. Track the overall direction of rates on the live Baltic Dry Index.
