Fuel costs depend on three simple inputs: how far you drive, how efficient your vehicle is, and the price per litre. Even small improvements in fuel efficiency can make a noticeable difference over a year.
How to estimate annual fuel cost
Multiply annual kilometres by litres per 100 km, divide by 100, then multiply by the fuel price per litre.
What affects fuel spend
- Vehicle size and efficiency
- City traffic versus highway driving
- Petrol versus diesel pricing
- Commute length and weekly driving patterns
Practical budgeting tip
Convert your annual total into weekly or monthly numbers. That is much easier to budget for than thinking only in per-litre prices.
Use the Fuel Cost Calculator to estimate yearly cost, monthly budget and one-off trip fuel spend.
