Commuter rail fares are on a zone-based system, with fares dependent on the distance from downtown. Rides between Zone 1A stations – South Station, Back Bay, most of the Fairmount Line, and eight other stations within several miles of downtown – cost $2.40, the same as a subway fare with a CharlieCard. Fares for other stations range from $5.75 from Zone 1 (~5–10 miles from downtown) to $14.50 from Zone 10 (~60 miles). All Massachusetts stations are Zone 8 or closer; only T.F. Green Airport and Wickford Junction in Rhode Island are Zone 9 and 10.

Interzone fares – for trips that do not go to Zone 1A – are offered at a substantial discount to encourage riders to take the commuter rail for less common commuting patterns for which transit is not usually taken. Discounted monthly passes are available for all trips; 10-ride passes at full price are also available for trips to Zone 1A. All monthly passes include unlimited trips on the subway and local bus; some outer-zone monthlies also offer free use of express buses and ferries. A cash-on-board surcharge of $3.00 is added for trips originating from stations with fare vending machines.

Starting in spring 2022, the MBTA began installing fare gates at North Station, South Station, and Back Bay station as part of its "Fare Transformation" project. These three stations are the start and end points of the vast majority of Commuter Rail trips, and the gates eliminate the possibility of passengers boarding without tickets or without having a single-use ticket invalidated (though conductors will still manually verify passengers leave the train in the zone they paid for). A common complaint from monthly pass holders was that on-board conductors would sometimes fail to check any tickets for their car, giving a free ride to single-ride and cash-on-board passengers. The new gates have scanners for bar codes on paper tickets, the mTicket app, Amtrak tickets, and military IDs. They also have a reader for tappable CharlieTickets (and CharlieCards, to prepare for potential future use on the Commuter Rail).
