Commuting in Las Vegas looks cheap until you add up everything that driving actually costs. Gas is only one line item — parking, maintenance, insurance, and depreciation all accrue per mile. This calculator puts the RTC monthly transit pass head-to-head against the true all-in cost of driving so you can see which one really saves money each month and each year.
How it works
The calculator runs two parallel cost models in your browser.
Driving cost (monthly):
Fuel = (round-trip miles x commute days / MPG) x gas price Ownership = round-trip miles x commute days x (IRS rate - fuel per mile) Driving total = Fuel + Ownership + Parking
The IRS standard mileage rate (about $0.67/mile for 2024) bundles fuel, maintenance, tyres, insurance, and depreciation into a single per-mile figure. Because you also enter gas and MPG directly, the tool subtracts the fuel-per-mile it already counted from the IRS rate so fuel is never double-charged.
Transit cost (monthly):
Transit = RTC 30-day pass (default $65)
It then compares the two totals and reports the monthly and annual savings of the cheaper option.
Worked example
A commuter drives a 24-mile round trip, 21 days a month, in a 27 MPG car, with gas at $4.10/gal and $50/mo parking:
- Monthly miles:
24 x 21 = 504 - Fuel:
504 / 27 x 4.10 = $76.53 - Fuel per mile:
$0.152 - Ownership:
504 x (0.67 - 0.152) = $261.07 - Parking:
$50.00 - Driving total: about $387.60/mo
Against a $65 RTC pass, transit saves roughly $322/mo — about $3,870 a year — for this commuter.
Notes
- Reduced-fare RTC passes (seniors, students, riders with disabilities) run about half the full-fare price. Edit the pass field to match.
- If you would keep your car regardless of how you commute, the marginal saving is smaller — compare only the per-mile driving cost against the pass.
- Gas prices and parking rates in the Las Vegas Valley vary widely between the Strip, downtown, and the suburbs. Use your own real numbers for the most accurate comparison.
