Calculation breakdown
- Fuel cost
- (15,000 km ÷ 100) × 8 L/100km × $2.00/L = $2,400.00
- Annual total
- Fuel + fixed costs = $9,990.00
- Cost per km
- $9,990.00 ÷ 15,000 km = $0.67
Assumptions
- All annual costs are entered as estimates and can vary between vehicles, insurers and states.
- Depreciation and finance interest are optional inputs so you can compare running cost with or without ownership costs.
- Fuel price and consumption are user inputs — actual bowser prices vary daily and by location.

How this calculator works
Enter your annual kilometres, fuel economy and pump price along with fixed costs such as registration, CTP, insurance, servicing and tyres. The calculator adds estimated depreciation to show total annual, monthly and weekly running costs, plus an effective cost per kilometre.
Frequently asked questions
Should I include depreciation?
Yes, if you want the true cost of ownership. Depreciation is usually the largest single cost in the first few years, even though you never pay it as a bill.
What fuel economy figure should I use?
Use your real-world litres per 100km from recent fill-ups rather than the manufacturer's combined figure, which is usually optimistic.
Does this include finance repayments?
No. Add loan interest separately using the Car Loan Calculator if your vehicle is financed.
