Formula 

Voyage Expenses = Port Charges + Cost of fuel consumed 

Voyage Time = Days at sea + Days in Port 

Net Freight = Freight as agreed — Brokerage commission 

Gross Daily Profit = Gross Profit / Voyage Time 

Gross Profit = Net Freight — Voyage Expenses 

Net daily Profit = Gross Daily Profit — Running Cost

Total Voyage Costs = Total Running Costs + Voyage Expenses

 

1. The aim of a voyage is to provide the ship owner or charterer with an estimate of the
