Ship Universe Maritime Tool
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.
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.
