What does your Tampa commute really cost?
A Tampa commute is more than gas. Driving adds parking — often around $90/month — plus per-mile wear and depreciation, while a HART monthly transit pass costs about $65. This calculator compares the true monthly cost of each so you can pick the cheaper option.
How it works
Driving cost combines fuel, IRS-rate wear, and parking; transit is the flat pass price:
roundTripMiles = oneWayMiles * 2
monthlyMiles = roundTripMiles * commuteDays
fuelPerMile = gasPrice / mpg
drivingCost = monthlyMiles * (fuelPerMile + irsWearRate) + parking
transitCost = hartPass
savings = drivingCost - transitCost
The IRS per-mile rate captures maintenance and depreciation that gas alone misses, which is why driving frequently costs more than it appears. The transit pass is a single fixed number regardless of distance.
Tips and example
For a 12-mile one-way commute, 21 days a month, at 3.30/gal and 28 MPG with 90 parking and an IRS wear rate of 0.21/mile: monthly driving miles total 504, fuel runs about 59, wear adds 106, and with parking the driving cost is roughly 255/month. The 65 HART pass saves about 190.
If you have free parking and a short drive, the math can flip toward driving — adjust the parking and distance inputs to see your break-even.
