Enter your ownership and travel assumptions
Fill in the fields below to compare annual car ownership cost against a travel alternative such as ride-hailing, rentals, transit, or a mix.
Example data table
This sample shows one realistic ownership scenario and the calculated crossover point between owning a car and using travel alternatives.
| Scenario | Purchase price | Resale value | Ownership years | Fuel efficiency | Alternative cost per mile | Break-even mileage |
|---|---|---|---|---|---|---|
| Urban commuter example | $30,000 | $15,000 | 5 | 30 mpg | $0.85 | 8,638 miles per year |
| Higher parking city | $30,000 | $15,000 | 5 | 30 mpg | $0.85 | 10,028 miles per year |
| Efficient hybrid case | $33,000 | $18,000 | 6 | 48 mpg | $0.90 | 7,401 miles per year |
Formula used
1) Annual depreciation
Annual depreciation = (Purchase price − Expected resale value) ÷ Ownership years
2) Annual capital cost
Annual capital cost = Average vehicle value × Finance or opportunity cost rate
3) Ownership variable cost per mile
Ownership variable cost per mile = (Fuel price ÷ MPG) + Variable maintenance per mile + Tire cost per mile
4) Total annual ownership cost
Total annual ownership cost = Annual fixed ownership cost + (Ownership variable cost per mile × Annual mileage)
5) Total annual alternative cost
Total annual alternative cost = Alternative fixed annual cost + (Alternative cost per mile × Annual mileage)
6) Break-even mileage
Break-even mileage = (Annual fixed ownership cost − Alternative fixed annual cost) ÷ (Alternative cost per mile − Ownership variable cost per mile)
If the denominator is zero or the result is negative, a practical positive break-even mileage may not exist.
How to use this calculator
- Enter your vehicle purchase price, expected resale value, and how many years you plan to keep it.
- Add annual fixed ownership costs such as insurance, registration, parking, and other recurring items.
- Provide fuel efficiency, fuel price, mileage-based maintenance, and tire cost per mile.
- Enter your expected yearly mileage so the tool can compare annual totals at your real usage level.
- Add the average cost per mile of your travel alternative plus any fixed annual subscription or pass cost.
- Click the calculate button to see the break-even mileage, yearly savings, monthly costs, and the comparison graph.
FAQs
1) What does break-even mileage mean?
It is the yearly mileage where total ownership cost equals the cost of using alternatives. Above or below that point, one option becomes cheaper than the other.
2) Which alternative works with this calculator?
You can compare ownership against ride-hailing, rentals, transit, car-sharing, or a blended travel plan. Just estimate one combined alternative cost per mile and any annual membership cost.
3) Why include depreciation?
Depreciation is usually one of the largest ownership costs. Even if you pay cash, the vehicle loses value over time and that loss should be counted.
4) Why is capital cost included?
Capital cost reflects financing interest or the opportunity cost of money tied up in the car. It helps make the ownership estimate more realistic.
5) What if the calculator says no practical break-even exists?
That means one option stays cheaper across normal positive mileage. Parallel or unfavorable cost lines can prevent a realistic crossover point.
6) Should I include parking and toll subscriptions?
Yes. Any recurring ownership cost should be included. Parking, permits, roadside cover, and subscriptions can materially change the break-even result.
7) Can I use kilometers instead of miles?
Yes, but keep every distance field in the same unit. If you use kilometers, fuel efficiency and per-distance costs must also match kilometers consistently.
8) How often should I update the inputs?
Update the calculator whenever fuel prices, insurance, parking, or resale expectations change. Revisiting assumptions every few months keeps comparisons accurate.
