Once the commuter leaves the station, they need another ticket for another trip. There is a flat single fare (Unitário) R$ 4.60 as of March 2020 regardless of distance. Single Journey with bus extension (Metrô na Superfície in Portuguese): Metro Rio operates a bus service from some of its stations, which acts as an extension of the metro service. No additional fee is charged for this service; however, when buying the ticket the traveller must ask for a Metrô na Superfície card. Cards can be bought directly on the Metrô na Superfície bus.

The fare costs R$4.35 as of April 2014, and the ticket can be purchased on the subway or when boarding select buses.
