How the pass break-even is calculated
The LIRR prices a ticket by the fare zone you start in and the zone you end in. There are eight zones in use: 1, 3, 4, 7, 9, 10, 12 and 14. Zone 1 is the Manhattan and Brooklyn terminals, Penn Station, Grand Central Madison and Atlantic Terminal, together with the stations nearest them. The zone numbers climb as you travel east, so a longer trip crosses more zones and costs more.
Peak fares apply on weekday trains scheduled to arrive at a New York terminal between 6:00 and 10:00 AM, or to leave one between 4:00 and 8:00 PM. Every other train, and every train on a weekend or holiday, is off-peak. Trips that stay entirely within zones 4 to 14, with neither end in the city, cost the same on every train.
Tickets are sold in the MTA TrainTime app, at station ticket machines and windows, and on board. Buying on board costs more than buying before you get on. Senior, disabled and Medicare fares are reduced and are not valid on weekday morning peak trains into New York. Weekly and monthly tickets cover unlimited travel between two zones for the period and are the usual choice for a five-day commute. The monthly pass break-even shown on each trip page is that pass price divided by the one-way peak fare, rounded up.
