A pre-fixture voyage estimate: gross and net freight, voyage days from distance and speed, bunkers and port costs, and the Time Charter Equivalent per day — the one number that lets you compare a spot voyage against a period rate.
Net freight after commission, minus bunkers, port disbursements and canal costs, gives the voyage result. Divided by the voyage days — sea days from distance and speed, plus port days — that is the Time Charter Equivalent you compare against a period rate.
This is the back-of-the-envelope every operator runs before fixing. The signed recap and the final voyage accounts are the binding numbers; this is for deciding whether the voyage is worth the offer in the first place.
Distances pair with the distance calculator; the full voyage result lives inside MarOps once the voyage is under way.
