Formula & Calculation Methodology
Total cost of ownership sums initial vehicle purchase price with recurring operational expenses (fuel volume required per year multiplied by fuel price, insurance premiums, maintenance budgets, and DMV fees) over the ownership tenure.
Worked Example
Purchasing a $16,500 pre-owned sedan for 5 years, driving 12,000 miles/yr at 26 MPG with $3.50 gas, $1,450 insurance, $1,200 maintenance, and $250 registration
Frequently Asked Questions
Why does a used car total cost of ownership frequently double its purchase price?↓
While used cars avoid initial steep depreciation, operating costs (fuel, insurance, tires, brakes, suspension components, and registration) accrue relentlessly every month. Over 5 years, recurring operational expenses typically exceed the purchase price.
How much should I realistically budget for used car repairs annually?↓
For vehicles aged 5 to 10 years, AAA and automotive mechanics recommend budgeting $1,000 to $1,500 annually. As vehicles surpass 100,000 miles, major repairs (alternator, timing belt/chain, suspension bushings, catalytic converter) become common.
Is buying a cheaper older car always more economical?↓
Not necessarily. A vehicle purchased for $5,000 that requires $3,000 in immediate engine or transmission repairs and gets 18 MPG can easily cost more per mile than an $11,000 reliable vehicle requiring $800 in yearly maintenance at 32 MPG.
Does this calculator include resale value at the end of ownership?↓
This calculation reflects gross cash expenditure. To find net cost after resale, subtract the vehicle projected market value (calculated using our Car Depreciation Calculator) from the Total Cost of Ownership.
What limitation should I keep in mind regarding vehicle insurance premiums?↓
Insurance premiums vary significantly by vehicle make, model theft rate, safety ratings, driver age, and postal zip code. Securing insurance quotes before purchasing prevents budget surprises.
