About Total Cost of Car Ownership Calculator
The Total Cost of Car Ownership Calculator computes the true 5-year financial impact of owning a vehicle by aggregating depreciation, loan interest, insurance, fuel, scheduled maintenance, and registration fees into an annualized and per-mile cost.
Formula & Mathematical Calculation
5-Year Total Cost = Depreciation + Loan Interest + Fuel Costs + Insurance + Maintenance & Repairs + Taxes/Fees
Cost per Mile = 5-Year Total Cost / ( Annual Miles × 5 )
Calculation Example
$32,000 Car (15k Miles/Yr): Depreciation ($14k) + Financing ($4k) + Insurance ($7.5k) + Fuel ($9k) + Maintenance ($3.5k) = $38,000 5-Year Cost ($7,600/year or $0.51 per mile).
