Use this tool to estimate the critical “wear and tear” portion of your vehicle’s cost of ownership, which primarily includes depreciation and non-routine maintenance, calculated on a per-mile basis.
Wear and Tear Cost Per Mile Calculator
Wear and Tear Cost Per Mile Calculator Formula
The calculation focuses on the non-fuel-related expenses of operating a vehicle.
$$\text{Cost per Mile} = \frac{(\text{Initial Cost} – \text{Resale Value}) + \text{Total Maintenance Cost}}{\text{Total Miles Driven}}$$
Variables Explained
- Initial Purchase Price: The price paid for the vehicle.
- Estimated Resale Value: The projected value of the vehicle at the end of the ownership period.
- Total Maintenance & Repairs: The estimated cumulative cost of oil changes, tires, non-routine repairs, and standard service during the ownership period.
- Total Expected Miles Driven: The total mileage accumulated on the vehicle over the ownership period (e.g., 3 years and 45,000 miles).

What is Wear and Tear Cost Per Mile?
Wear and tear cost per mile is a crucial metric that quantifies the expense of operating a vehicle, excluding variable costs like fuel and insurance (which often have their own specific per-mile calculations). This cost is primarily driven by two components: **Depreciation** (the loss of vehicle value over time and use) and **Maintenance** (the costs incurred to keep the vehicle operating due to mechanical wear). Understanding this number allows individuals and businesses to make more informed purchasing decisions and accurately budget for transportation expenses.
For example, a luxury vehicle might have a very high initial cost and a steep depreciation curve, resulting in a high wear and tear cost per mile, even if its actual repair costs are average. Conversely, an economical vehicle with low depreciation and minor repair needs will have a significantly lower per-mile cost, making it financially cheaper to drive over the long term. This metric is indispensable for budgeting, tax reporting (for business use), and comparing the long-term financial feasibility of different vehicles.
How to Calculate Wear and Tear Cost Per Mile (Example)
Let’s use a hypothetical example to demonstrate the calculation steps:
- Determine Total Depreciation: A car is bought for $40,000 and is expected to be sold for $18,000. $$\text{Depreciation} = \$40,000 – \$18,000 = \$22,000$$
- Calculate Total Non-Fuel Costs: Add the total estimated maintenance costs (e.g., $3,500) to the depreciation. $$\text{Total Cost} = \$22,000 + \$3,500 = \$25,500$$
- Determine Total Miles: The owner expects to drive the vehicle 75,000 miles during the ownership period.
- Solve for Cost Per Mile: Divide the total cost by the total miles. $$\text{Cost per Mile} = \frac{\$25,500}{75,000 \text{ miles}} = \$0.34 \text{ per mile}$$
Frequently Asked Questions (FAQ)
TCO is a comprehensive figure that includes all costs: depreciation, maintenance, fuel, insurance, licensing, and financing interest. Wear and Tear Cost typically focuses only on depreciation and maintenance/repairs, which are directly related to the vehicle’s usage and age.
Does this calculator include gas costs?No. This calculator is specifically designed to isolate the non-fuel-related expenses associated with the vehicle’s physical degradation (depreciation and repairs). Fuel costs are highly variable and are usually calculated separately.
How can I estimate my Resale Value?You can use online valuation tools (like Kelley Blue Book or Edmunds) and search for comparable vehicles with similar mileage and age in your local market. Be conservative with your estimate to avoid underestimating your true cost.
What if my Resale Value is higher than my Initial Cost?While rare (usually only happening with collector or limited-edition vehicles), the formula handles this: a negative depreciation (or appreciation) results in a lower, or even negative, wear and tear cost per mile, indicating a profitable ownership experience.
