Calculator Inputs
This page uses a single-column page flow. The form itself switches to three columns on large screens, two on medium screens, and one on mobile.
Example Data Table
This sample uses the default example inputs included in the calculator.
| Purchase Price | Years Owned | Annual Miles | Monthly Cost | Yearly Cost | Cost Per Mile | Estimated Resale |
|---|---|---|---|---|---|---|
| $32,000.00 | 5.0 | 12,000 | $963.27 | $11,559.23 | $0.96 | $15,053.66 |
Formula Used
1) Loan payment
Monthly Payment = P × r ÷ (1 − (1 + r)^−n)
Here, P is loan principal, r is monthly interest rate, and n is total loan months.
2) Depreciation
Resale Value = Purchase Price × (1 − Depreciation Rate)^Years Owned
Depreciation Cost = Purchase Price − Resale Value
3) Fuel cost
Total Miles = Annual Miles × Years Owned
Fuel Gallons = Total Miles ÷ MPG
Fuel Cost = Fuel Gallons × Fuel Price Per Gallon
4) Total mobility cost
Total Cost = Depreciation + Interest + Upfront Taxes and Fees + Fuel + Insurance + Maintenance + Repairs + Parking + Tolls + Cleaning + Subscriptions + Registration and Annual Taxes
5) Benchmark outputs
Monthly Cost = Total Cost ÷ (Years Owned × 12)
Yearly Cost = Total Cost ÷ Years Owned
Cost Per Mile = Total Cost ÷ Total Miles

FAQs
1) What does this calculator measure?
It estimates the full cost of keeping and using a vehicle over your ownership horizon. It combines depreciation, financing interest, fuel, insurance, maintenance, repairs, parking, tolls, subscriptions, taxes, and fees into one view.
2) Why is depreciation included?
Depreciation reflects how much value your vehicle loses while you own it. Even if you paid cash, the vehicle typically becomes worth less over time, so depreciation is a real ownership cost.
3) Does the total include loan principal?
No. The economic total uses depreciation plus financing interest rather than the full loan payment stream. That avoids double counting the vehicle’s value and focuses on the real cost of owning and using it.
4) What if I do not finance the car?
Set APR to zero and make the loan amount zero by entering the full purchase through cash, down payment, or trade-in. The calculator will still estimate depreciation and operating costs correctly.
5) How should I estimate depreciation?
Use a conservative annual percentage based on vehicle age, brand, mileage, and market conditions. Newer vehicles often depreciate faster in early years, while older cars may lose value more slowly.
6) Can I use this for comparing two vehicles?
Yes. Run the calculator once for each vehicle using the same ownership period and mileage assumptions. Then compare monthly cost, yearly cost, cost per mile, depreciation, and financing interest.
7) Why does cost per mile matter?
Cost per mile converts ownership and usage expenses into one easy comparison number. It helps when deciding between commuting options, fleet vehicles, reimbursement rates, or keeping an older car longer.
8) Are taxes and parking optional?
Yes. Leave any optional item at zero if it does not apply to your situation. The calculator is designed to work with simple or detailed inputs without breaking the overall cost estimate.
