Compare Transport Costs
Enter your car ownership costs and public transport usage to compare monthly expenses. Fill out at least basic car and public transport numbers to get started.
The car vs transit cost debate hits different when you run actual numbers. A coworker of mine sold her Honda Civic after realizing she spent $847 per month just to park at work—on top of insurance, gas, and maintenance. Six months into a $127 metro pass plus occasional Uber rides, she's banking $400 per month and wondering why she waited so long.
But here's where people slip up: they compare the transit pass to their car payment and call it a day. That ignores insurance you pay even when the car sits idle, registration fees, oil changes, tires, and the depreciation nobody thinks about until trade-in day. On the flip side, going car-free sounds cheap until you add rideshares for airport runs, grocery Ubers, and late-night rides home. This calculator pulls those hidden lines into one comparison so you see the real gap.
Which Side Wins for Your Numbers?
Car ownership typically costs $600 to $1,200 per month when you add every line item: payment or depreciation, insurance, fuel, maintenance, parking, and registration. Public transit plus rideshare usually runs $150 to $500 depending on city pass prices and how often you call an Uber.
The break-even point often sits around 15,000 miles per year in cities with decent transit. Drive less and transit wins; drive more (or live where transit doesn't reach your job) and the car may justify itself. Parking costs in dense cities can single-handedly tip the scale.
Get Your Result in Three Steps
Enter Your Car Costs
Monthly payment (or set to $0 if owned outright), insurance premium, estimated fuel based on miles and MPG, maintenance budget, parking fees, and registration divided by 12.
Enter Your Non-Car Costs
Monthly transit pass price, per-ride fares for trips outside the pass, rideshare frequency and average cost, plus any bike-share or scooter rentals you use.

Fixed Costs That Tip the Scale
Most people underestimate car ownership because they focus on variable costs like gas. But fixed costs—insurance, registration, parking—hit your wallet every month whether you drive one mile or one thousand.
Insurance: $100 to $300 per month depending on coverage, driving record, and location. Young drivers and urban zip codes pay more.
Parking: $0 in suburbs with free lots, $150 to $400 per month in city centers. Residential permits add another layer.
Registration & taxes: Divide your annual fees by 12. Some states charge property tax on vehicles too.
A car sitting in a garage untouched still costs you insurance, registration, and depreciation. Transit passes and rideshare have no equivalent idle cost—you only pay when you ride.
Real Scenario: Chicago Commuter
Setup: Marcus lives in Lincoln Park and works downtown. He currently drives but is considering ditching the car for CTA.
Current Car Costs:
- Car payment: $380/month
- Insurance: $145/month
- Gas (600 miles at 28 MPG, $3.80/gal): $81/month
- Maintenance: $75/month average
- Downtown parking: $280/month
- Registration: $25/month
- Total car: $986/month
Transit Alternative:
- CTA monthly pass: $105/month
- Uber/Lyft (8 rides at $18 avg): $144/month
- Divvy bike-share: $17/month
- Total non-car: $266/month
Result: Going car-free saves Marcus $720 per month—$8,640 per year. The car costs 3.7 times more than transit plus rideshare. Even if he doubled his Uber budget for convenience, he'd still save $576 monthly.
Situations That Flip the Winner
Suburban sprawl with no transit
If the nearest bus stop is two miles away and runs once an hour, rideshare costs explode. A paid-off car with cheap insurance may win.
Free employer parking
Remove a $200 parking line and the car gap shrinks fast. Some employers subsidize transit passes too—check both sides.
High-mileage sales jobs
If you drive 25,000 miles per year for work, fuel and depreciation climb but the car may still be essential. Factor in mileage reimbursement if offered.
Electric vehicle with home charging
EVs cut fuel costs by 60 to 80 percent. If you own an EV outright and charge at home, the car side gets much cheaper.
Surge pricing zones
Living in an area where Uber regularly surges 2x to 3x can double your rideshare budget. Track a few weeks before committing.
Trimming Either Side of the Ledger
If you keep the car:
- Shop insurance annually—rates vary wildly by company.
- Negotiate or hunt for cheaper parking. A lot two blocks farther may cost $100 less.
- Drive a fuel-efficient vehicle. Jumping from 20 MPG to 35 MPG cuts fuel cost nearly in half.
If you go car-free:
- Buy annual transit passes when discounted—some cities offer 10 to 15 percent off.
- Use scheduled rides over on-demand to avoid surge pricing.
- Combine errands to reduce total rideshare trips.
Top Questions
Should I include depreciation if I own my car outright?
Technically yes—your car loses value every year whether you have a payment or not. But for a practical month-to-month comparison, focus on cash costs. Depreciation matters more when deciding to sell.
What about time costs?
This calculator focuses on money. Commute time varies by route and mode. Some people value the productivity of reading on a train; others value the flexibility of driving.
Can I combine both—keep a car but use transit for commuting?
Yes. Run the numbers with reduced car mileage and lower rideshare use. You still pay fixed car costs, but fuel and parking may drop significantly.
How do I estimate maintenance costs?
AAA publishes annual driving cost studies. A rough rule: budget $0.06 to $0.10 per mile for maintenance on a typical sedan. Older cars trend higher.
Does this work for motorcycles or scooters?
Plug in your actual costs—insurance, fuel, maintenance—and compare. Two-wheelers often have lower fixed costs but similar parking challenges in cities.

Frequently Asked Questions
Common questions about monthly transport cost comparison.
Does this tool use real fuel or ticket prices?
No. This tool does not use real fuel prices, transit fares, or any live data. It uses the numbers you enter yourself. You need to look up current fuel prices, transit pass costs, and ridehailing rates in your area and enter them into the calculator. The tool then performs simple math based on your inputs.
Why might my real costs be different from these estimates?
Many factors can affect actual costs: fluctuating fuel prices, seasonal transit pass discounts, surge pricing for ridehailing, unexpected car repairs, changes in your driving or transit usage, parking rate changes, insurance rate changes, and many other variables. This tool provides a snapshot comparison based on the numbers you enter at one point in time. Real costs will vary month to month and year to year.
Does this include car depreciation or resale value?
No. This tool does not account for car depreciation, resale value, or the long-term financial impact of owning a car. It only compares monthly operating costs (payment, insurance, fuel, maintenance, etc.) versus monthly public transport and ridehailing costs. For a complete financial picture, you would need to consider the total cost of ownership over time, including depreciation, which this tool does not calculate.
How can I make a more accurate comparison with my own data?
To make a more accurate comparison, gather your actual numbers: recent fuel receipts to calculate average fuel cost, your actual car payment and insurance statements, maintenance records, parking receipts, your transit pass cost or recent ticket purchases, and recent ridehailing receipts. Enter these real numbers into the calculator. Keep in mind that even with accurate data, costs can change, and this tool is still only an educational comparison, not financial advice.
What if I only use one option (car or public transport)?
You can still use this tool by entering zero for the option you don't use. However, the comparison will be incomplete. The tool will show a warning if one side has all zeros. For a meaningful comparison, try entering realistic estimates for both options based on what you might use if you switched.
Does this account for time savings or convenience?
No. This tool only compares monetary costs. It does not account for time savings, convenience, flexibility, environmental impact, or other non-monetary factors. A car might be faster for some trips, while public transport might allow you to work or relax during your commute. These factors are important but outside the scope of this cost comparison tool.
