Defaults: 21 workdays a month and 25 MPG are our assumptions; change them. Gas is EIA's Florida average for the week of Oct 19, 2026. Tolls default to $0 because Turnpike and I-95 Express tolls vary by route and time: enter yours from the Turnpike or 95 Express. See AAA for today's pump prices.

Since October 1, 2026, a Tri-Rail one-way ticket costs $3 to $10 depending on zones traveled: 1 zone $3, 2 zones $4, 3 zones $6, 4 zones $7, 5 zones $8, 6 zones $10. A monthly pass is $121, a regional monthly pass with Miami-Dade Transit is $165 and a weekend/holiday day pass is $5.
How do I count Tri-Rail zones?
Count every zone you pass through, including the zone you start in and the zone you end in. Boca Raton (zone 3) to MiamiCentral (zone 6) is 4 zones, so $7 one way.
What is the IRS mileage rate for 2026?
76 cents a mile for business use from July 1 to December 31, 2026 (72.5 cents from January 1 to June 30). It covers gas, wear, insurance and depreciation, but not tolls or parking. We use it as a full-cost benchmark; the IRS does not allow a deduction for ordinary commuting.
Is Tri-Rail parking free?
At most stations, yes. Boynton Beach, Fort Lauderdale Airport/Dania Beach, Pompano Beach, Miami Airport and the Lake Worth Beach auxiliary lot are pay-to-park, but registered riders get 12 hours a day free. 24-hour parking is not allowed (SFRTA Tariff Policy §8.15).
How is this calculated?
Driving at the IRS rate = miles × 2 × 76¢ + tolls + parking. Gas only = miles × 2 ÷ MPG × gas price + tolls + parking. Tri-Rail = the round-trip fare × workdays, capped at the $121 monthly pass. Brightline = 2 rides a workday at the per-ride price of the 40-ride SMART pass; your real cost depends on which passes you buy and how long they last. Driving miles are approximate station-to-station routes from OpenStreetMap (OSRM). Year = month × 12.
