Spain in numbers
Spain has a population of 47.9 million (2025) and a GDP of 1.69 trillion euros (about 1.91 trillion US dollars) in 2025.
Paying everyone €500 a month would cost 287 billion euros a year (about 325 billion US dollars), or 17.0% of GDP. That equals 50.0% of central government expense (2023), 57.4% of its revenue (2024), and 114% of its tax revenue (2024).
Children only (under 18: 7.59 million) would cost 45.5 billion euros a year (2.7% of GDP); adults only (18 and over: 40.3 million), 242 billion euros (14.3%).
Default amount: €500 a month is a round figure chosen by the editors for this calculator. For comparison, the World Bank's poverty line of $3.00 a day is about €55 a month here; paying that to everyone would cost 1.9% of GDP.
How to read this
This is the gross cost: the total paid out. The real net cost depends on which taxes fund it, which benefits or tax breaks it replaces and whether the payment is taxed. The population, budget and GDP figures are not all from the same year (see the sources).
