"My car payment is only $380 a month" is the sentence that gets most car owners into trouble, because a loan payment is maybe 40% of what a car actually costs. AAA's annual "Your Driving Costs" study puts the full cost of owning a new midsize sedan — loan, insurance, fuel, maintenance, tires, depreciation, and fees — at roughly $12,000 a year, or about $1,000 a month, for someone driving 15,000 miles annually. A monthly transit pass in most major U.S. cities costs $70-$130. That's not a rounding error, it's an $800-$900/month gap. Here's how the two options actually stack up, line by line.
The Full Cost of Car Ownership (Often Underestimated)
Most people mentally budget only the loan payment and gas. Here's what a typical new-car owner driving 12,000-15,000 miles/year actually pays across a full year, based on 2026 AAA and Edmunds cost data:
| Cost Category | Monthly (avg.) | Annual |
|---|---|---|
| Loan payment (5-yr, new car) | $525 | $6,300 |
| Insurance | $165 | $1,980 |
| Fuel | $155 | $1,860 |
| Maintenance & repairs | $95 | $1,140 |
| Depreciation (beyond loan) | N/A* | N/A* |
| Registration, fees, parking | $65 | $780 |
| Total (excl. depreciation loss) | ~$1,005 | ~$12,060 |
*Depreciation is baked into the loan-to-resale-value gap; a new car loses 20-30% of its value in year one alone, which functionally adds thousands more to the true cost of ownership beyond monthly cash outflow.
The Cost of Public Transit
Transit pricing varies a lot by city, but unlimited monthly passes cluster in a predictable range:
- New York City (OMNY/MetroCard): $132/month
- Chicago (CTA): $105/month
- Washington D.C. (SmarTrip, capped fares): ~$120/month for regular commuters
- Mid-sized metro systems (Portland, Denver, Minneapolis): $60-$100/month
- Smaller city bus systems: often $40-$70/month
Even at the top end (NYC's $132), a transit rider spends roughly $1,584/year — about 13% of what full car ownership costs. At the lower end of the range, the gap widens even further.
What You Give Up (and What You Don't)
Cost comparisons that stop at dollars miss half the picture. Transit riders trade convenience and flexibility for savings — but they also gain commute time back (reading, working, or resting on a train instead of watching traffic) and avoid the stress of parking in dense downtowns. On the other side, car owners gain door-to-door flexibility, which matters enormously for irregular schedules, families with young kids, or areas genuinely underserved by transit.
A realistic middle path many households land on: drop to one car per household instead of two, and use transit plus occasional rideshare for the second set of trips. Going from two cars to one typically saves $8,000-$10,000/year in avoided ownership costs, even after adding $50-$100/month in rideshare spending.
When a Car Still Wins
The math doesn't always favor transit. If you already own a paid-off, reliable car with cheap insurance and low annual mileage, your marginal cost of continuing to drive it can be lower than switching to transit plus rideshare for occasional car needs. Car ownership also tends to win economically in areas with sparse transit coverage, where "transit" effectively means long walks plus infrequent buses plus multiple transfers — at that point the time cost outweighs the dollar savings for most people.
4 Questions to Answer Before You Decide
- How many of your regular trips does transit actually cover? If it's under 60-70% of your weekly trips, you may end up paying for both transit and rideshare, eroding the savings.
- What's your car's real resale/trade-in value right now? Selling a car you rarely use converts a depreciating asset into cash you can invest or use to pay down debt.
- How much is your time worth on your specific commute? A 45-minute transit commute vs. a 25-minute drive is a real cost, even if it's not a dollar figure on a receipt.
- Could one household car work instead of two? This is usually the single biggest lever — going from two cars to one often saves more than eliminating cars entirely would if it made your life meaningfully harder.
