Ship voyage ETA calculator
The Voyage ETA Calculator estimates steaming time by dividing practical voyage distance by average speed. A routing allowance can be added to the entered nautical-mile distance to represent a simple operational adjustment before the sea-time calculation.
Fuel and bunker cost estimate
If daily consumption is entered, the calculator estimates total sea-passage fuel from calculated sea days. Adding a bunker price provides an indicative total bunker cost and fuel cost per nautical mile.
ETA assumptions
Actual arrival depends on routing, weather, currents, traffic, speed restrictions, manoeuvring, port instructions and vessel performance. This calculator is a planning reference and does not replace the vessel passage plan or official operational ETA.
Voyage ETA Calculator FAQ
What inputs are required?
Voyage distance in nautical miles and average speed in knots are required. Departure, routing allowance, fuel consumption and bunker price are optional.
What does the routing allowance do?
It increases the entered distance by the selected percentage before sea time is calculated. It is a simple planning allowance, not a weather-routing forecast.
Is the ETA an official operational ETA?
No. It is an indicative calculation and should be checked against the passage plan, routing, vessel performance and operational instructions.
