How to Use the Car-Free vs. Car Ownership Cost Compare Calculator
When people weigh going car-free against owning a car, they usually focus on the sticker price and forget the recurring costs that quietly add up every month. This calculator lets you enter your transit and rideshare spending alongside a car's insurance, registration/tax, fuel, parking, and depreciation, then compares the two paths side by side so you can see exactly which one costs more per year — and by how much.
Transit costs vary enormously by city — a monthly unlimited pass runs around $132 in New York City, while other metro areas charge quite a bit less or more, so swap in your own city's fare before relying on the result. Car ownership costs split into fixed expenses like insurance and registration that you owe regardless of mileage, and variable costs like fuel and parking that scale with how much you actually drive. Adding depreciation — the value a car loses each year just by aging — captures a real cost that never shows up as a monthly bill but affects your net worth all the same.
If you split your trips between transit and the occasional rideshare, just add both monthly amounts into their respective fields. When the two totals land close together, it's worth thinking beyond the dollar figure — commute-time transit crowding, flexibility for last-minute errands, and how much you value not driving in traffic can all tip the decision one way or the other.
Frequently Asked Questions
Yes, if you want an accurate comparison. A car loses value every year, and that loss is a real cost of ownership even though you don't write a check for it. If you don't know the amount, leave it at 0 and compare the other costs first.
If the costs are similar, factor in non-financial things like convenience, how crowded transit is during your commute, and how often you need to travel on short notice.
