Bunker fuel cost calculator for tonnes, litres and voyage estimates
Estimate indicative bunker fuel cost per tonne or per litre, convert VLSFO, MGO and IFO380 quantities using explicit density assumptions, then move to live port prices or a firm supplier quote.
Typical defaults: VLSFO 0.991 kg/L, MGO 0.860 kg/L, IFO380 0.980 kg/L. Always confirm density from the supplier certificate for final delivery.
Estimated bunker fuel cost
Estimated cost range for 500 metric tonnes of VLSFO.
Uses a reference VLSFO midpoint where no specific live port indication is selected. This is not a firm supplier quote.
How the bunker fuel cost estimate works
Convert quantity
Litres × density ÷ 1,000 = metric tonnes. Metric tonnes × 1,000 ÷ density = litres.
Apply indication
The calculator uses a selected Bulugo port indication where available, otherwise a practical reference midpoint for the grade.
Show range
The output applies a narrow indicative range around the midpoint to avoid presenting a single number as a supplier quote.
Important limitation
This calculator is not a firm bunker quote and does not replace supplier confirmation. Final delivered cost can change with port dues, barge fees, delivery window, credit, viscosity, sulphur specification, density certificate and commercial terms.
Bunker fuel cost, per-litre conversion and voyage questions
Searchers often ask for bunker fuel cost, bunker fuel cost per tonne, bunker fuel price per litre, and density conversion for litres per metric ton. The practical answer is always a two-step calculation: convert the quantity with a transparent density assumption, then multiply by a price indication or firm quote.
How do you calculate bunker fuel cost?
Bunker fuel cost is quantity in metric tonnes multiplied by the selected bunker price per metric tonne. If the starting quantity is litres, convert litres to tonnes first using density in kg/L.
How many litres are in one metric ton of VLSFO?
Using a typical VLSFO density of 0.991 kg/L, one metric tonne is about 1,009 litres. Actual delivered volume depends on the supplier certificate and temperature correction.
How many litres are in one metric ton of MGO?
Using a typical MGO density of 0.860 kg/L, one metric tonne is about 1,163 litres. Use the actual density for final delivery and invoicing checks.
Is the calculator a firm bunker quote?
No. The calculator gives an indicative estimate only. Firm supplier quotes depend on vessel, port, quantity, delivery window, credit and supplier availability.
Move from indicative calculation to live market action
Use the calculator for planning and sharing assumptions. Use live prices and supplier quote paths when the purchase needs a real commercial number.
