Car Maintenance Cost Calculator

Estimate routine maintenance and wear-and-tear costs based on vehicle category (sedan, SUV, truck, luxury, EV), vehicle age, and annual miles driven.

Calculation Results

Vehicle Maintenance Budgeting Model

Annual Maintenance = (Annual Miles × Base Cents/Mile × Age Multiplier) / 100
  • Class Base Rates: Sedans (~7.2¢/mi), SUVs (~8.8¢/mi), Trucks (~10.5¢/mi), Luxury (~12.8¢/mi), EVs (~5.1¢/mi).
  • Age Multipliers: 0-2 yrs (1.0x factory warranty), 3-5 yrs (1.35x), 6-9 yrs (1.75x), 10+ yrs (2.2x).
  • Monthly Reserve = Annual Maintenance / 12.

Step-by-Step Worked Example

Scenario: Budgeting maintenance for a 5-year-old midsize SUV driven 12,000 miles/year

Calculation Steps:

  1. Effective Rate per Mile = 8.8¢ × 1.35 = 11.88¢ per mile
  2. Estimated Annual Maintenance = (12,000 × 11.88¢) / 100 = $1,425.60 / year
  3. Monthly Sinking Fund = $1,425.60 / 12 = $118.80 / month
  4. Recommended Emergency Fund = $1,069.20
Result: Budget $118.80 per month ($1,425.60/year) to cover routine servicing and unexpected wear items.

Frequently Asked Questions

Do electric vehicles really require less maintenance?

Yes. Electric cars have no motor oil, spark plugs, timing belts, alternators, or exhaust systems. Regenerative braking also extends brake pad life to over 70,000–100,000 miles, reducing routine maintenance expenses by 35% to 45% compared to gas vehicles.
