Example Data Table
| Scenario | Annual Distance | Fuel Cost | Depreciation | Total Annual Cost | Cost Per Kilometer |
|---|---|---|---|---|---|
| Sample commuter sedan | 15,000 | $1,500.00 | $3,400.00 | $9,290.00 | $0.6193 |
| Higher-use family vehicle | 22,000 | $2,250.00 | $4,100.00 | $12,780.00 | $0.5809 |
| Lower-use city car | 10,000 | $900.00 | $2,600.00 | $7,150.00 | $0.7150 |
Formula Used
Fuel Cost = (Annual Distance ÷ Fuel Efficiency) × Fuel Price
Depreciation = (Purchase Price − Expected Resale Value) ÷ Ownership Years
Annual Parking = Monthly Parking × 12
Annual Tolls = Monthly Tolls × 12
Fixed Cost = Depreciation + Insurance + Registration + Parking + Finance Cost + Washing
Variable Cost = Fuel + Maintenance + Repairs + Tires + Tolls
Total Annual Cost = Fixed Cost + Variable Cost
Monthly Cost = Total Annual Cost ÷ 12
Cost Per Kilometer = Total Annual Cost ÷ Annual Distance
Future Year Cost = Current Annual Cost × (1 + Inflation Rate)
Use the same distance system throughout. If you enter miles and mpg, the cost per distance still works correctly.

FAQs
1. What costs are included here?
This calculator includes fuel, depreciation, insurance, registration, maintenance, repairs, tires, parking, tolls, washing, and finance cost. It combines fixed and variable expenses for a fuller ownership estimate.
2. Does the calculator include depreciation?
Yes. Depreciation is calculated from purchase price, expected resale value, and ownership years. This helps reflect value loss, which is often one of the largest real car ownership costs.
3. Can I use miles instead of kilometers?
Yes. You can use miles and mpg, or kilometers and km/l. Keep both distance and fuel efficiency in matching units so the per-distance result remains accurate.
4. Why is cost per kilometer useful?
Cost per kilometer helps compare vehicles, routes, or commuting choices. It also supports delivery pricing, reimbursement estimates, and better driving budget decisions.
5. Are parking and tolls fixed or variable?
Parking is treated as a fixed recurring cost here. Tolls are grouped with variable costs because they often rise with driving frequency and travel patterns.
6. How is the projection calculated?
The projection starts with your current annual total cost. Each later year is increased by the inflation rate you enter, producing a simple forward-looking ownership estimate.
7. Can this help compare two vehicles?
Yes. Enter one vehicle’s values, record the results, then repeat with the second vehicle. Comparing annual cost and cost per kilometer can reveal the better budget choice.
8. Do I need financing to use it?
No. If your car is fully paid off, enter zero for annual finance cost. The calculator still works for depreciation, fuel, maintenance, and other ownership expenses.
