Car Servicing Budget Calculator
Estimate your annual car servicing budget from your average service cost and how often your vehicle needs servicing.
Your results
Calculation breakdown
- Annual servicing
- Annual servicing = cost per service × (12 / interval in months)
- Total budget
- Total budget = annual servicing + unexpected repair allowance
Worked example
A $350 service every 12 months plus a $500 unexpected repair allowance gives a recommended annual budget of $850.
Assumptions
- Service intervals vary by manufacturer, model and driving conditions.
- Unexpected repair allowance is a discretionary buffer amount.
- This annualises a time-based interval only. If the logbook also sets a kilometre interval, budget using whichever limit your driving is likely to reach first.

How this calculator works
Divide your typical service cost by your servicing interval to estimate an annual budget for routine car maintenance. Add an allowance for unexpected repairs to get a more realistic yearly running cost figure to set aside.
Frequently asked questions
How often should I service my car?
Check your manufacturer's logbook or owner's manual, as intervals vary by make, model and whether it's time-based, distance-based or both.
Should I include tyres in this?
You can add an allowance for tyres, brakes and other wear items into the unexpected repair allowance if they aren't part of your standard service cost.
Does dealer servicing cost more than independent mechanics?
Prices vary. Servicing by a qualified independent repairer does not remove your Australian Consumer Law consumer-guarantee rights. Manufacturer warranty conditions generally require the maintenance schedule and service standards to be met, while an optional extended warranty may have additional terms, so check the relevant documents when comparing quotes.
