A voyage estimate points at calculating the profit or loss that a vessel will make from a proposed voyage. In other words, voyage estimates are basically profit and loss accounts for the specific voyage in address that are arrived at by calculating the income and after that subtracting all related expenses. Not at all like time charters, in voyage charters all the vessel-related costs that include working costs (crew costs, repairs and maintenance, insurance, stores and lubes, etc.) and voyage (variable) costs (fuel, diesel oil, harbour levy and costs, canal tolls, etc.) are paid for by the shipowner. Consequently, a voyage estimate must take under consideration freight income (bill of lading amount loaded on the ship in tons by freight rate in dollars) and subtract all voyage-related costs, counting address commission and brokerage.
