Total Cost of Car Ownership Calculator

Depreciation is often one of the largest vehicle costs, even though it is less visible than fuel or insurance. Excluding it can make ownership appear cheaper than reality. Including a reasonable depreciation estimate improves full-cost comparison across vehicles.

It is a planning estimate based on the annual cost categories you enter. Accuracy improves when you use realistic mileage, insurance, and maintenance values from your own records. Treat it as a decision metric, then refine as real costs emerge.

Yes. Running ownership scenarios before purchase can prevent budget surprises. Compare at least two vehicles with different fuel economy and depreciation assumptions. This often reveals that lower monthly payment does not always mean lower total ownership cost.

Not directly unless you include it in your annual cost assumptions. This tool focuses on ownership burden across major categories. For loan-specific analysis, pair it with a payment and amortization calculator to separate financing effects from operational costs.

Start with a conservative annual average and test a higher scenario for out-of-warranty years. Maintenance costs are uneven over time, so scenario ranges are more useful than a single precise estimate. Re-run annually with actual spend.

Yes. Run one case for your current vehicle and one for the replacement option. Use consistent mileage and price assumptions across both. The annual and per-mile outputs make replacement tradeoffs easier to evaluate objectively.
