Port Fee Calculator
Calculate total port charges from vessel size, duration, pilotage, and towage requirements.
About this calculator
Port calls generate several separate categories of charges that a vessel operator needs to budget for together, and this calculator adds them up from five inputs: gross tonnage, length of stay, pilotage hours, tug count, and berth type. Port dues and light dues are both charged as a flat rate per gross ton (GT), so a larger vessel pays proportionally more of both regardless of how long it stays. Berth charges scale with gross tonnage AND length of stay together, and the daily rate itself depends on berth type -- this calculator uses illustrative per-GT-per-day rates that differ for an alongside berth, anchorage, and container terminal, since terminals typically charge more for the additional handling infrastructure. Pilotage is a base callout fee plus an hourly rate for the time a pilot actually spends aboard guiding the vessel in and out.
Towage is charged per tug, doubled to cover both the arrival and departure operations, since most vessels need tug assistance on both moves rather than just one. Finally, an agency fee combines a flat administrative charge with a small percentage of port dues, reflecting the local agent's coordination role. All six charge categories are summed into a total port cost, which is also expressed as a cost-per-day figure by dividing by the length of stay -- useful for comparing port calls of different durations on a like-for-like basis. The dollar rates used throughout are illustrative planning figures, not live tariff schedules from any specific port authority, since actual port dues and terminal rates vary widely by port and are published separately by each authority.

How to Use This Calculator
- Enter the vessel's gross tonnage (GT) from the vessel's certificate of registry.
- Input the planned port stay in days and pilotage hours required.
- Enter the number of tugs used and select the berth type (alongside, anchorage, or container terminal).
- Review the total port cost broken down into port dues, berth charges, pilotage, and towage.
- Use the total cost in voyage cost calculations and charter rate negotiations.

Frequently Asked Questions
Why does a larger vessel pay more even before considering how long it stays?
Port dues and light dues are both charged per gross ton in this calculator, so they scale directly with vessel size regardless of the length of stay. A vessel with double the gross tonnage pays roughly double the port dues and light dues for the same visit, before berth charges (which also factor in stay length) are added.
How does berth type change the total cost?
Berth charges are calculated as gross tonnage times a per-day rate that depends on berth type, times the number of days in port -- this calculator uses different illustrative daily rates for an alongside berth, anchorage, and container terminal, with container terminal berthing typically priced highest to reflect the added cargo-handling infrastructure.
Why is towage cost doubled relative to a single tug operation?
The calculator multiplies the per-tug rate by the number of tugs and then by two, because most vessels require tug assistance for both the arrival maneuver into berth and the departure maneuver back out to open water -- two separate operations, not one, even though the same tugs and crew are typically used for both.
What does the cost-per-day figure add that the total cost doesn't show?
Total cost mixes charges that scale with time in port (like berth charges) with charges that are essentially one-time per visit (like pilotage and towage). Dividing the total by the number of stay days gives a comparable daily rate, which is useful when weighing a shorter, more expensive-per-day call against a longer stay that amortizes the one-time charges over more days.
