HarborCosts
Port cost calculation engine — transform vessel data, tariffs and operational parameters into detailed, accurate cost breakdowns for any port call scenario.
The problem with port cost estimation
Port costs are one of the largest variable expenses in shipping — yet most companies still estimate them from outdated spreadsheets, PDF tariff books or manual broker quotes. The result: inaccurate budgets, missed discount opportunities and limited ability to compare port alternatives.
HarborCosts replaces manual estimation with a structured calculation engine. It ingests vessel parameters, port tariffs and operational details to produce itemized, auditable cost breakdowns — available through an API that integrates directly with planning and management systems.
- Itemized cost breakdown by fee category and tariff component
- Side-by-side scenario comparisons across ports and vessel configurations
- Historical cost reconstructions using versioned tariff data
- Discount and surcharge calculations including environmental incentives
- Structured API responses for system-to-system integration
Key Capabilities
From vessel parameters to cost intelligence — every capability is available via API.
Calculate itemized port cost components — fairway dues, quay charges, ISPS fees, waste fees, passenger charges — with full transparency.
APIModel cost outcomes across different ports, vessel configurations and call durations to support optimal route and port selection.
APIReconstruct port cost estimates for past calls using historical tariff versions and actual vessel data for auditing and benchmarking.
APIApply the correct tariff version for any date — past, present or future — ensuring accurate calculations across tariff changes.
APIFactor in environmental vessel scores and green port incentives that affect fees, discounts and surcharges at participating ports.
APIExpose every calculation as a commercial REST API endpoint — enabling system-to-system integrations with full cost breakdowns in structured responses.
