What this calculator does
This calculator compares the monthly cost of commuting in Dallas by transit with the full cost of owning and driving a car — payment, insurance, gas, maintenance, parking and tolls. DART runs the largest light-rail network in Texas, but most Dallas commuters drive, and many use North Texas Tollway Authority roads such as the Dallas North Tollway and President George Bush Turnpike. Paying by TollTag is cheaper than being billed by mail through ZipCash.
How to use it
- Keep the DART 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.
Worked example for Dallas

| Parking | $110 |
| Tolls | $140 |
| Car total | $1,172 |

Transit saves you about $1,016 / month.
What changes the answer in Dallas
Dallas budgets benefit from no state income tax, but tolls, car costs and property tax add up for many households. 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.
