About Bunker Cost Calculator

Bunkers are bought by mass but delivered by volume, so the density at the reference temperature converts between them — a key check on the bunker delivery note. All-in cost per tonne adds barging and delivery charges, which can be significant for small stems.

Formula

Bunker cost

Total = quantity x price per tonne + delivery fees; volume = quantity / density

Worked example

With the default values below, Bunker Cost Calculator returns Total bunker cost of $531,200.00. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

  • The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax or compounding frequency into account.
  • Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
  • Marine results are planning estimates only. Verify against the vessel's approved stability booklet, loading manual, class society rules and applicable maritime regulations before loading or sailing.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

Why does density matter commercially?

Because volume is measured on delivery and converted to mass. An incorrect density or temperature correction moves the invoiced quantity by tonnes.

What is a short delivery?

When the mass actually received is less than invoiced, usually detected by comparing tank soundings with the bunker delivery note figures.
