Car Maintenance Cost Calculator
How much does car maintenance cost per year? This car maintenance cost calculator estimates your yearly spend from two things that matter most: how much you drive and how old the car is. Results are ranges from illustrative U.S. budget assumptions — not quotes.

Estimate basis & methodology
Estimate basis: cost figures are illustrative U.S. budgeting assumptions. A dated source table has not been verified for these ranges; they should not be treated as current national averages. Actual costs vary by vehicle, location and shop. Get a written quote before authorizing any repair.
How the estimate works: a ~5-year-old car driven 12,000 miles/year is the $600/year reference point (midpoint of the assumed budget range). Newer cars scale down (0.7×), aging cars scale up (1.4–1.8×), and mileage scales proportionally. The ±25% band is an illustrative allowance, not a measured confidence interval.
Key figure
Model reference: $600/year at 12,000 miles equals 5¢/mile. This is a planning assumption for routine maintenance and wear, not an independently verified national average or a complete ownership-cost estimate.
Worked example (you can verify by hand)
Input: 15,000 miles/year, 9-year-old car.
- Mileage factor: 15,000 ÷ 12,000 = 1.25
- Age factor (8–11 yr band): 1.4
- Midpoint: 600 × 1.25 × 1.4 = $1,050
- Range: $1,050 × 0.75 – $1,050 × 1.25
Expected output: $788–$1,313 per year (estimate).
Limitations — what this cannot do
- Covers routine maintenance and common repairs only — not fuel, insurance, depreciation or financing.
- Exotic, electric-only and very high-mileage (>200k mi) vehicles fall outside the reference band.
- A single bad year (transmission, engine) can exceed the annual range; the calculator smooths costs across years.
- The mileage-only scaling returns zero at zero miles and omits time-based service costs that can still apply.
FAQ
How much should I budget yearly for car maintenance?
For a mid-life car at average mileage, budget roughly $600–$900/year as a planning figure; newer cars less, cars over 8 years old more. Use the calculator above with your own mileage and age.
Does this include tires?
The reference budget includes an allowance for tire wear; it does not predict tire life for your vehicle. For a separate tire budget, divide your quoted set price by an explicit mileage-life assumption and multiply by your annual miles. Label that assumption and revise it using actual wear and the tire and vehicle manufacturers’ guidance.
Why a range instead of one number?
Parts, labor, vehicle requirements and shop location can change a quote. The displayed band reflects model assumptions and is not a measured confidence interval; compare written quotes for the work your vehicle needs.
Is an older car always more expensive to maintain?
On average, yes after about year 7–8, when wear items (suspension, cooling, seals) start failing together. But a well-kept older car can still beat a neglected newer one — service history matters more than age alone.
