Public transport fares in the Île-de-France are set using a system of concentric fare zones radiating from central Paris, and are implemented with a mixture of paper and electronic tickets. Prices are determined by the regional autorité organisatrice de transports ("Regional Transport Organisational Authority"), which for Île-de-France is the Syndicat des transports d'Île-de-France (STIF).
In 1900, a second-class Paris Métro ticket cost 15 centimes of the old franc, and a first-class ticket 25 centimes. In 1960, it cost 37 centimes of the new franc. Six hundred million Métro tickets were sold that year, an average of around 1,500 a minute.

The fare zones were put in place after the ticket fare structure had been decided. These concentric zones, numbered 1 to 8 (until 1 July 2007), are centred on Paris, with zone 1, the most central, covering the commune of Paris, zone 2 surrounding it, and so on. Zone 8 is the most distant from the centre, and was only used in the south-east of the Île-de-France.
