What this calculator does
This calculator compares the monthly cost of commuting in Atlanta by transit with the full cost of owning and driving a car — payment, insurance, gas, maintenance, parking and tolls. MARTA runs rail and bus service with a $2.50 fare and a $95 30-day pass, but most Atlanta commuters drive. The Peach Pass express lanes on I-75, I-85 and GA-400 charge dynamic tolls.
How to use it
- Keep the MARTA transit cost or change it to your actual fare spend.
- Enter your car payment, insurance and typical parking and tolls.
- Enter commute miles, driving days and other driving.
- Compare the totals and the per-mile cost.
The formula
Monthly car cost = payment + insurance + (monthly miles ÷ mpg × gas price) + (monthly miles × maintenance per mile) + parking + tolls. Monthly miles = daily round trip × days per week × 52 ÷ 12 + other miles. Transit cost = pass or fares + occasional rideshare.

What changes the answer in Atlanta
Atlanta costs less to live in than most big coastal cities, but a car is close to essential, and commutes can be long. Parking is often the swing factor in dense neighborhoods, while in spread-out areas the lack of transit coverage can make a car necessary regardless of cost.
Common mistakes and tips
- Counting only gas as the cost of driving.
- Ignoring depreciation — even a paid-off car loses value every year.
- Forgetting pre-tax commuter benefits: many employers let you pay transit and parking with pre-tax dollars (up to the IRS monthly limit).
- Comparing without counting time; a longer transit trip can still be worth it if you can read or work.
