Denver Driving vs Transit: What a Commute Really Costs

Cost example updated November 4, 2026

The short answer: transit wins on cash, by $7,536 a year.

Driving the example Denver commute costs $8,592 a year, about $716 a month, at full cost. The same commute on RTD costs $1,056 a year, $88 a month, on a monthly pass. Even counting fuel and parking only, driving costs $3,458.40 a year, still more than the pass. What driving buys is time and flexibility, which this page does not price.

This page is the commute comparison. The Denver city door is the whole car.

The Denver city door prices a $42,000 pickup in Denver over 5 years: $71,620. This page answers a narrower question for Denver commuters: driving to work against riding RTD, on the same trip, priced per year.

The example commute, stated up front

Every input is stated here so you can check the math and swap in your own numbers:

Round trip: 30 miles (15 miles each way).
Days: 5 days a week, 48 weeks a year, or 240 commute days.
Commute miles: 30 times 5 times 48 is 7,200 miles a year.
Driving rate: 86 cents a mile, AAA's 2026 average for a typical new car, via the cost per mile page.
Parking: $10 a day, a stated example assumption, not a surveyed Denver rate. Parking varies a lot by garage and neighborhood, so swap in your own daily parking cost and the rest of the math still works.
RTD Monthly Pass: $88 a month, standard fare, from RTD's own fares page, checked November 4, 2026.
Denver gas: $4.41 a gallon, the Colorado state average on October 24, 2026, from the Denver city door.
Example sedan: 30 miles per gallon, a stated example. The pickup variant uses 19 miles per gallon, from the Denver city door.

Driving: the full cost

Driving cost: 7,200 miles times 86 cents is $6,192 a year.

Parking cost: $10 a day times 240 days is $2,400 a year.

Total: $6,192 plus $2,400 is $8,592 a year.

Split by period, the same total reads:

Per day: $25.80 of driving plus $10 of parking, $35.80.
Per week: $129.00 of driving plus $50 of parking, $179.00.
Per month: $8,592 divided by 12, $716.00.
Per year: $8,592.

Transit: the RTD side

RTD's standard fares, from RTD's own fares page: a 3-Hour Pass is $2.75, a Day Pass is $5.50, and a Monthly Pass is $88. RTD has two fare zones, Local and Airport, so a regular Denver commute pays the flat local fare. With Tap-n-Ride or a MyRide account, fares are capped: 3-Hour Passes automatically convert to Day and Monthly Passes, so a rider never pays more than the Day Pass in a day or the Monthly Pass in a month.

For this commuter, the Monthly Pass is the cheaper path: $88 a month times 12 is $1,056 a year, or $4.40 per commute day. Paying per ride would cost $5.50 a day, capped at the Day Pass, which is $1,320 over 240 days, so the pass saves $264 a year against paying per ride. Discount fares run $27 a month for a Monthly Pass, or $324 a year, for seniors 65 and older, riders with disabilities, Medicare recipients, and LiVE enrollees. Against the $8,592 driving total, the discount pass leaves a gap of $8,268 a year. Youth 19 and under and active-duty military ride free.

The gap

Driving at full cost, $8,592 a year, against RTD on a Monthly Pass, $1,056 a year, leaves a gap of $7,536 a year. That is $628 a month and $31.40 a day ($35.80 driving minus $4.40 transit). The pass costs about 12% of the driving total.

Formula

The example commute is a 30 mile round trip, 15 miles each way, 5 days a week, 48 weeks a year, or 240 commute days, which is 7,200 miles a year. Driving cost is 7,200 miles times 86 cents, which is $6,192 a year. Parking cost is $10 a day times 240 days, which is $2,400 a year. The total is $6,192 plus $2,400, which is $8,592 a year.

The RTD Monthly Pass is $88 a month times 12, which is $1,056 a year, or $4.40 per commute day. Driving at full cost, $8,592 a year, against RTD on a Monthly Pass, $1,056 a year, leaves a gap of $7,536 a year, which is $628 a month and $31.40 a day. The break-even point is 16 days a month: $88 divided by $5.50. A 5-day-a-week commuter rides about 20 days a month, so the pass wins: 20 times $5.50 is $110, against $88 for the pass. A 3-day-a-week commuter rides about 12 days a month, so paying per ride wins: 12 times $5.50 is $66, against $88 for the pass.

Monthly pass or pay per ride?

The break-even point is 16 days a month: $88 divided by $5.50. A 5-day-a-week commuter rides about 20 days a month, so the pass wins: 20 times $5.50 is $110, against $88 for the pass, a saving of $22 a month. A 3-day-a-week commuter rides about 12 days a month, so paying per ride wins: 12 times $5.50 is $66, against $88 for the pass, a saving of $22 a month the other way. Count your own commute days and pick the cheaper side.

If you already own the car

The full-cost view charges the commuter for insurance and value loss the owner pays whether the car commutes or sits in the driveway. The fuel-only view counts just what the commute itself adds: fuel plus parking.

Sedan at 30 miles per gallon: 7,200 miles divided by 30 is 240 gallons. At $4.41 a gallon, fuel is $1,058.40 a year. Add $2,400 of parking for $3,458.40 a year. Against the $1,056 pass, transit still wins by $2,402.40 a year.

Pickup at 19 miles per gallon: at $4.41 a gallon, fuel is $1,671.16 a year. Add $2,400 of parking for $4,071.16 a year. Against the $1,056 pass, transit wins by $3,015.16 a year.

So even for a driver who already owns the car, the pass is cheaper on cash in this example. The car still wins on schedule freedom and on trips transit does not serve well, which this page does not price.

What this leaves out

Time. Transit may take longer door to door than driving, or shorter at rush hour. This page prices cash only, so check your own route times on both sides.
Route coverage. Not every Denver commute has a good RTD route. Check your own route and schedule before counting the pass saving.
Parking is an assumption. The $10 a day is stated so the example is checkable, not a claim about what parking costs in your part of Denver.
The 86 cents is a national average. It is AAA's average for a typical new car, not a Denver-only figure. The Denver city door prices a car in Denver itself, at $71,620 over 5 years for the $42,000 pickup example.
Airport trips. Trips to or from Denver International Airport need an Airport Day Pass at $10, but the $88 Monthly Pass already includes airport travel.
Denver drivers already fund RTD. The Denver sales tax on a car includes 1% for RTD, which is $420 on a $42,000 car. That is part of the purchase tax, not part of the commute math above.

Questions people actually ask

In Denver, does driving beat transit on cost?
