Fuel Cost Calculator for Ships & Marine Operations

The Fuel Cost Calculator estimates the total cost of marine fuel consumption based on fuel quantity, daily consumption rate, or engine-specific fuel oil consumption (SFOC) combined with power and operating time. It is designed for voyage planning, bunker estimation, and operational cost control in commercial shipping.

The calculator supports pricing per tonne or per cubic meter, applies density correction where required, and allows additional fees or markup to be included for realistic bunker cost evaluation.

Calculation Methods

Three independent calculation methods are available depending on the data at hand:

  • From total fuel quantity: Calculates cost directly from total fuel mass (tonnes) or volume (m³), converting between units using fuel density at 15 °C.
  • From daily fuel consumption: Estimates total fuel usage from a daily consumption rate (t/day) multiplied by voyage duration in days and hours.
  • From SFOC & power: Computes fuel consumption from engine power, operating time, and specific fuel oil consumption expressed in g/kWh.

Fuel Pricing & Density Conversion

Fuel price can be entered per tonne or per cubic meter. If price per cubic meter is used, the calculator converts it to an equivalent price per tonne using the specified fuel density. This allows consistent cost comparison across different bunker pricing formats.

Typical density values range between 0.96–1.01 t/m³ depending on fuel grade (VLSFO, HSFO, MGO), but custom values can be entered to match bunker delivery notes.

Markup, Fees & Realistic Cost Estimation

Optional markup and fees can be applied as a percentage of the fuel subtotal. This allows inclusion of supplier margins, port charges, barge fees, or contractual adjustments in the final cost figure.

Applications

  • Voyage cost estimation and budgeting
  • Bunker planning and supplier comparison
  • Charter party fuel cost analysis
  • Operational cost control and reporting
  • Marine engineering and fleet performance studies

Notes on Accuracy

Results are intended for engineering and planning purposes. Actual fuel cost may vary due to fuel quality, weather conditions, engine efficiency, and contractual pricing terms. Always verify calculations against bunker delivery documentation and vessel-specific performance data.
