How to calculate yacht fuel cost – The boat fuel cost calculator

When you decide to enjoy a charter, there are many things you have to consider, not only when and where and whom you wish to join the party. I’m talking about the costs and expenses you will have during this memorable holiday with your loved ones. Depending on what type of vessel you are about the rent and the destination you will discover (as every place has its prices, pros, and cons), you will have a different bill at the end of your cruise

How do I calculate yacht fuel cost? 

When you charter a power yacht, the most critical cost to support is for sure fuel.

When you rent a sailboat or hire a catamaran, don’t forget about the fuel cost for generators, the outboard engine of the dinghy. It would be a different cost at the end (definitively lower than aboard a motor yacht), but pay attention to air conditioning, especially when you spend the night at anchor. 


Yacht fuel calculation: how it works

It’s time to take a map and find on it all the spots and destinations you wish to reach! Keep in mind that you can predict the weather conditions only 10 to 7 days before embarking.

Prepare your sailing itinerary.

Your sailing route will depend on many factors, as the engine power and cruising speed of the yacht, the weather conditions, and the nautical miles you intend to navigate. Naturally, you will have to be informed about the actual market price of the fuel in the destination you will sail to have the right or most approximate calculation of the boat fuel cost


Together with the assistance and suggestions of our sales department, our experienced technicians created an advanced, quick, and efficient tool for the yacht fuel calculation that we call the “Boat fuel calculator.” This tool allows you to have a concrete and actual analysis of the yacht fuel consumption and price, starting with your itinerary plan on the map to the final result. 


Let’s begin: select the point of embarkation of your charter on the map. Now continue pinning all the beautiful spots you want to reach by boat during your yacht charter (as you can see, the calculator automatically updates the number of nautical miles) to disembark. You will obtain the total number of miles. 

Calculate the nautical miles

Naturally, you can choose the unit of measures (nautical miles, miles, km): in this case, it would be the nautical miles and, every time you pin a new destination on your map, from the embark to the disembark, the tool updates the total number of miles cruised. 

Now that we have the total number of miles, mandatory to calculate the boat fuel cost of our cruise. We need to know the yacht’s cruising speed, the engine consumption, and the market price of diesel in our next sailing destination.

Engine power and consumption


Now that we have the nautical miles, we need to know the engines’ power (the hp) and the real engine consumption of the boat we rent to have the actual yacht fuel calculation

The last essential element we need to obtain the yacht fuel cost of our charter is the market price of gas in the destination we will sail. To have the diesel’s actual merits, you can consult many updated webpages of marinas and fuel bunkers, which continuously report the existing fuel prices day by day. (You can also check at

The fuel consumption formula


What we are looking for is the expense of fuel we will have during our cruise.

Now that we have all the information we need for the yacht fuel calculation, and so:

  • Total nautical miles;
  • Engine consumption;
  • Cruising speed;
  • The market price of gas;

We can proceed with the real boat fuel calculator using our formula. 

Firstly, we need to know our charter’s travel time; I’m referring to the cruise duration. The formula to obtain the cruise duration is determined by dividing the number of nautical miles by the number of knots (the boat’s cruising speed). 


For example, if the nautical miles we are planning to navigate are 150 nm and the cruising speed of our yacht is 18 knots:

150 nm / 18 kn = 8,333 hr 

So if we want to cruise in a total of 150 nautical miles with a cruising speed of 18 knots, we will take about 8,333 hours. You will always have to consider the sea and weather conditions, which will influence the engines’ consumption.

And now that we have the “time,” the “duration” of our charter? How to calculate the yacht fuel cost? 

If the engine of our boat consumes 250 lt/hr, we have to multiply the time of our cruise, so in this case, 8,333 hr by the boat fuel consumption, so by 250 lt/hr:

8,333 hr / 250 lt/hr = 2.082,50 lt

2.082,50 are the liters we consume cruising for 8,333 hr with engine consumption of 250 lt/hr. Now we have to multiply the number of liters just obtained by the market price of fuel, that we can suppose at 1,50 Euro/lt:

2.082,50 lt x 1,50 Euro = 3.123,75 Euro


Let’s resume the “magic formula” for yacht fuel calculation. If your sailing itinerary contemplates 150 nautical miles at a constant cruising speed of 18 knots, 250 lt/hr consumption, and marine diesel cost of 1,50 Euro/lt, at the end of our yacht charter, we will have a bill of 3.123,75 Euro.

The calculations of boat fuel cost are always approximate and depend on sea and weather conditions and atmospheric and natural events.
