When to use this calculator
Use this cost of ownership calculator to estimate the monthly cost of having a vehicle beyond the loan or lease payment. It is useful for comparing cars by real budget impact instead of sticker price alone.
Formula
Monthly ownership cost = payment + insurance + fuel or charging + maintenance + fees
- Payment is the monthly loan or lease amount.
- Insurance, fuel, maintenance and fees are monthly estimates.
- The result combines recurring ownership costs into one monthly total.
Worked example
With a $650 payment, $180 insurance, $220 fuel, $120 maintenance and $80 in fees, the calculator estimates total monthly vehicle ownership cost.
Common mistakes
- Budgeting only for the car payment.
- Underestimating maintenance for older or high-mileage vehicles.
- Ignoring parking, tolls, registration or seasonal tire costs.
