Total Annual Cost = Annual Fuel Cost + Insurance + Maintenance + Registration + Depreciation

These formulas help you understand the financial impact of your vehicle ownership.

Worked Example

Let's calculate the annual cost of a personal vehicle:

Purchase price: $25,000
Annual mileage: 15,000 miles
Fuel efficiency: 25 miles per gallon
Fuel price: $3.50 per gallon
Insurance: $1,200
Maintenance: $500
Registration: $200
Depreciation: $1,500

Using the formulas above, the total annual cost would be approximately $3,375 for fuel, plus $3,400 for other expenses, totaling $6,775 per year.
