The MBTA has various fare structures for its various types of service.
The CharlieCard electronic farecard is accepted on the subway and bus systems, but not on commuter rail, ferry, or paratransit services.
Passengers pay for subway and bus rides at faregates in station entrances or fareboxes in the front of vehicles; MBTA employees manually check tickets on the commuter rail and ferries.

Since the 1980s, the MBTA has offered discounted monthly passes on all modes for the convenience of daily commuters and other frequent riders.
One-day and seven-day passes, intended primarily for tourists, are available for buses, subway, and inner harbor ferries.

The MBTA has periodically raised fares to match inflation and keep the system financially solvent.
A substantial increase effective July 2012 raised public ire including an "Occupy the MBTA" protest.
A transportation funding law passed in 2013 limits MBTA fare increases to 7% every two years.
A 5% fare increase effective July 1, 2014 was implemented.
