How it is calculated
Tyres per year = set price × annual distance ÷ lifespan. Parking per year = monthly × 12.
Annual total = sum of all items. Cost per distance = total ÷ annual distance.
Worked example
Using the calculator’s example values:
- Annual distance: 12,000 km/year
- Annual insurance: $450.00
- Annual road tax: $100.00
- Roadworthiness test (yearly average): $40.00
- Servicing and oil per year: $300.00
- Price of a set of tyres: $400.00
- Tyre lifespan: 40,000 km
- Repair reserve per year: $200.00
- Parking or garage per month: $0.00
- Other yearly costs (washes, tolls…): $60.00
Result: Annual cost of keeping the vehicle — $1,270.00 (monthly cost: $105.83; cost per distance (excl. fuel): $0.106/km; tyres per year: $120.00).
Money-saving tips
- Shop around for insurance before each renewal.
- Follow the manufacturer’s service schedule to avoid bigger repairs.
- Check pressures and alignment: they extend tyre life.
Frequently asked questions
Does it include fuel?
No, so you can compare it across cars. Add it with the monthly fuel calculator.
What about depreciation?
Not either. It is real but hard to estimate; you can add it under “other costs”.
How much should I reserve for repairs?
It depends on the car’s age and condition. Use what you spent in previous years as a guide.
