About this tool
Going car-free has become realistic for many city-dwellers. This tool gives you a side-by-side cost comparison so you can decide whether your monthly miles justify a car payment, insurance, gas, and parking - or if rideshare is cheaper.
How it works
Car = Payment + Insurance + Gas + Maintenance
Lower mileage favors rideshare. Higher mileage with cheap parking favors ownership. Don't forget time, convenience, and emergencies in your decision.

Frequently asked questions
At what mileage does owning a car beat rideshare?
It depends on rideshare prices, but generally above 600 to 1,000 miles per month, owning a car becomes cheaper. Below 400 miles per month, rideshare often wins, especially in cities with parking costs.
Does this include car depreciation?
Include depreciation in your monthly car payment if you own outright. Cars typically depreciate $200 to $500 per month for the first 5 years. Lease payments already include depreciation.
What about parking costs?
In major cities, parking can add $200 to $700 per month. Add this into your insurance/maintenance line. Parking is typically free in suburbs.
Should I include a buffer for emergencies?
Add 10-15% to maintenance for unexpected repairs. Cars over 5 years old should have a higher buffer ($150+ per month) since major repairs become more frequent.
