About the Car Maintenance Cost Calculator
This car maintenance cost calculator builds a realistic maintenance budget from the services your car actually needs. For each item — oil changes, tyre rotations, tyres, brakes, filters, the 12-volt battery and fluid services — enter how many miles it lasts and what your shop charges, and the calculator spreads each cost over the miles you drive in a year. Add a reserve for unexpected repairs to get a yearly, monthly and per-mile figure.
Use it to set aside a monthly amount for car upkeep, to compare the running cost of two vehicles, or to understand what each mile really costs you beyond fuel. Rideshare and delivery drivers can use the per-mile result in their earnings maths, and families can plug the yearly total into a household budget.
The defaults are typical for a mainstream gasoline car but are placeholders — check your owner’s manual for the recommended intervals and get local prices. Set an item’s interval to 0 to leave it out (for example, oil changes on an electric car). Costs are spread evenly, so a $800 tyre purchase every 50,000 miles counts as $0.016 per mile even though you pay it all at once.
With the default inputs, the yearly maintenance cost is $1,053.00. Change any value above to recalculate instantly.
How to use the car maintenance cost calculator
- 1Enter how many miles you drive in a year.
- 2Check each service interval against your owner’s manual and adjust it.
- 3Enter what your shop or dealer charges for each item.
- 4Add a yearly reserve for unexpected repairs.
- 5Review the yearly, monthly and per-mile cost and the item breakdown.
Formula and method
Each service item is converted into a yearly cost by working out how many times you will need it at your annual mileage (miles ÷ interval, which can be a fraction) and multiplying by the price. This spreads infrequent big-ticket items like tyres, brakes and batteries evenly across the years you drive, which is how you should save for them.
The repairs reserve is a flat yearly amount for things that are not on a schedule (a water pump, sensor or suspension part). The projection sums the yearly total over your chosen number of years, increasing it each year by the price-increase rate. Time-based services (such as a battery that ages out regardless of mileage) can be approximated by entering the miles you typically drive in that time.

Worked examples
Typical sedan driven 12,000 miles a year
Oil changes ($120), rotations ($50), tyres ($192), brakes ($135), filters ($56), battery ($50) and fluids ($50) total $653 a year. Adding a $400 repair reserve gives $1,053 — $87.75 a month or 8.8¢ a mile. Over five years with 3% price increases that is about $5,591.
High-mileage commuter, 20,000 miles a year
At 20,000 miles every item comes around more often: scheduled maintenance rises to about $1,088 a year. With an $800 repair reserve for an older car the total is $1,888, or 9.4¢ per mile, and $5,665 over three years.
Electric car with no oil changes
Removing oil and fluid services and doubling brake life (regenerative braking does much of the work) cuts scheduled maintenance to $415.50 a year. With a $300 reserve, budget about $60 a month.
Frequently asked questions
How much should I budget for car maintenance each year?+
It depends heavily on the car, its age and your mileage. With this calculator’s mainstream-car defaults, 12,000 miles a year works out to about $650 of scheduled maintenance plus a $400 repair reserve, roughly $1,050 a year or $88 a month. Plug in your own intervals and shop prices for a figure that fits your car.
How do I calculate maintenance cost per mile?+
Add up everything you expect to spend on maintenance and repairs in a year and divide by the miles you drive. For example, $1,050 over 12,000 miles is about $0.09 per mile.
Do electric cars cost less to maintain?+
Usually, yes. EVs have no oil changes, spark plugs or exhaust, and regenerative braking makes brake pads last much longer. Tyres can wear faster because EVs are heavy, and cabin filters and coolant still need service.
Does maintenance cost go up as a car ages?+
Yes. Scheduled items stay similar, but unscheduled repairs become more common after warranties end and as parts wear out. Increase the repairs reserve for cars over about 8 years old or past 100,000 miles.
How often should I change my oil?+
Follow your owner’s manual or the car’s oil-life monitor. Many modern cars using synthetic oil specify 5,000–10,000 miles between changes, with shorter intervals for severe use such as towing, short trips or dusty conditions.
