How to Use This Calculator
  1. Enter the voyage distance in nautical miles and average speed in knots.
  2. Input daily fuel consumption in metric tons per day and the current bunker price per MT.
  3. Set the sea margin percentage (typically 5-15%) to account for adverse weather.
  4. Review total fuel required in MT, total fuel cost, and voyage duration in days.
  5. Check CO₂ emissions output for IMO DCS reporting and emissions planning.

What each input means

Voyage Distance
Total voyage distance in nautical miles.
Average Speed
Average vessel speed over ground.
Daily Consumption
Main engine fuel consumption per day at sea.
Fuel Price
Current bunker fuel price per metric ton.
Sea Margin
Extra fuel allowance for weather, currents, and routing. Typical: 5-15%.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Voyage Distance = 5000, Average Speed = 14, Daily Consumption = 35, Fuel Price = 600 = 5 input(s) provided
  2. Calculate Total Fuel Required
    Total Fuel Required
    572.9 = 572.9
  3. Calculate Total Fuel Cost
    Total Fuel Cost
    343750 = $343,750
  4. Calculate Voyage Duration
    Voyage Duration
    14.88 = 14.88
  5. Calculate CO₂ Emissions
    CO₂ Emissions
    1784.1 = 1784.1
