Online marine calculators for shipping
The calculators a shipping desk reaches for, in one place, online: some free with no sign-up, all of them working from the same voyage.
Free, with no sign-up
The sea distance calculator gives the distance between any two of 1,300+ ports in nautical miles and kilometres, on the real sea route, with the canals on the way. Enter a speed and it becomes a transit time calculator, with the sailing days. Ready-made pages list the distances between the busiest ports.
An online vessel voyage estimator
The Voyage Estimator is a ship voyage cost estimator online: enter the vessel and the port rotation and see the whole voyage, with the first estimates free. There is nothing to install, and it works on a phone as well.
Every calculation of a voyage
Inside the estimator the calculators work together: the fuel consumption and bunker cost, the port cost of each call, the canal tolls, the charter hire, the cost per TEU and slot cost, the voyage P&L, the TEU utilization and break-even, and the weather and deviation check.

Which calculators are free?
The sea distance and transit time calculators are free with no sign-up, and the Voyage Estimator gives you free estimates to start.
Do they work on a phone?
Yes. They run in the browser on a computer or a phone.
Do the calculators share their figures?
Yes. Inside the estimator one voyage drives them all, so a change to a port or a speed updates every figure.
