Editable example

An example is filled in. Replace it with your own data to calculate.

Enter total distance, kilometers per liter and fuel price per liter.

Enter trip distance (km), for example 300. Use the displayed unit; replace the example with your own value.
For 15 km/L enter 15. This is not liters per 100 km.
Enter fuel price (twd per litre), for example 30. Use the displayed unit; replace the example with your own value.

Example result

Estimated fuel cost

750TWD

Add both legs of a return trip. Tolls, parking, rental fees and extra fuel while idling are excluded.

Estimated fuel use25 L

Enter fuel economy in km/L and fuel price in TWD/L yourself.

Method and scope

Litres required equals kilometres divided by kilometres per litre. Multiply by the entered fuel price for estimated cost.

Fuel efficiency here means distance per litre, not litres per 100 km. A larger efficiency value means less fuel for the same trip.

The price is your input rather than a live quote. Tolls, parking, rental charges, idling and changing road conditions are excluded.

What this helps you do

Estimate fuel needed and fuel cost for a route. Enter the complete trip distance, including the return journey if relevant.

What to enter

Start with trip distance (km), then fill the other relevant fields in the units shown. The field hints explain the required format and examples.

How the calculation works

Litres required equals kilometres divided by kilometres per litre. Multiply by the entered fuel price for estimated cost.

Worked example

A 300 km trip at 15 km per litre needs 20 litres. At TWD 32 per litre, fuel costs TWD 640.

Understanding the answer

Fuel efficiency here means distance per litre, not litres per 100 km. A larger efficiency value means less fuel for the same trip.

Scope and limitations

The price is your input rather than a live quote. Tolls, parking, rental charges, idling and changing road conditions are excluded.
