Fuel Cost Calculator

Estimate trip fuel use and travel cost from distance, fuel efficiency and fuel price.

Estimated fuel used
40 L
Estimated fuel cost
$60.00

How it works

Fuel litres = kilometres × litres per 100 km ÷ 100; cost = litres × price.

Worked calculation

A 500 km trip at 8 L/100 km and $1.50 per litre costs $60. For the sample inputs, the calculator displays these results:

Frequently asked questions

How is fuel cost computed?

Distance times consumption (litres per 100 km) gives litres used, which is multiplied by price per litre.

How do I convert from MPG?

L/100 km = 235.215 ÷ MPG (US).

Does it include tolls or wear?

No. Fuel only.
