Ship Fuel Consumption Calculator

Calculate vessel fuel consumption, bunker cost, voyage fuel requirement, CO₂ emissions and annual fuel spend. Use Simple mode for a fast distance-and-speed estimate or Advanced mode for laden, ballast, auxiliary and port consumption.

Fuel Consumption
Sea + port fuel with optional weather and safety margins
Cost Analysis
Voyage bunker cost, cost/day, cost/nm and annual fuel spend
Emissions
Editable fuel CO₂ factors and optional carbon-cost exposure

Voyage Profile

Estimate sea time from nautical miles and average speed, then add expected port or idle days.

Fuel Consumption Results

Simple voyage fuel estimate

Enter voyage data
Enter voyage distance, speed, fuel burn and bunker price to calculate total ship fuel consumption and voyage bunker cost.
Planning estimate only. Actual vessel consumption depends on machinery condition, loading, trim, weather, sea state, currents, hull and propeller condition, fuel quality, generator demand and operational practice. CO₂ factors are editable planning defaults and may not match the factor required for a specific regulatory or contractual calculation. Confirm vessel-specific consumption curves and applicable emissions rules before commercial decisions.
