Being financed exclusively by membership fees, the Círculo carries out its activities entirely independently. The membership amounts to 226 on July 1, 2018.
The revenue budget for 2018 amounts to 1.86 million Euro from fees. The fees run in various tranches between 2,000 and 35,000 Euro per year, primarily according to the number of employees of the companies with whom the members are connected.
An amount (18,150 Euro) must be added to this income, assigned to sponsorship of the Barometer of the Círculos, the publication of which is shared with the Círculo de Economía and the Círculo de Empresarios Vascos. This consists of ring-fenced sponsorship provided by Ferrovial.
