Automotive calculator FAQ
- What does it really cost to own a car?
- Beyond the payment, ownership includes fuel, insurance, maintenance, and depreciation. Use the fuel cost, auto insurance, vehicle maintenance, and car depreciation calculators together for a full picture.
- How is a car lease payment calculated?
- A lease payment combines depreciation (capitalized cost minus residual value, spread over the term), a finance charge based on the money factor, and sales tax. The car lease calculator shows each part.
- How do I calculate fuel cost for a trip?
- Divide the distance by your vehicle's fuel economy to get gallons or liters used, then multiply by the fuel price. The fuel cost calculator handles the math, including round trips.
