UNRWA is funded almost entirely by voluntary contributions, outside of a very limited subsidy from the Regular Budget of the United Nations, which is used exclusively for administrative costs. UNRWA's work, in close collaboration with host governments and other partners could not be carried out effectively without the sustained generous contributions received from states and regional governments, the European Union, and other partners, which represent over 92 per cent of all contributions.
In 2013, 43.7 per cent of the Agency’s income of 1.18bn came from EU member states, who contributed US$ 517.6 million, including through the European Commission. The United States and the European Commission were the largest individual donors, contributing a cumulative 42.6 per cent of the Agency’s overall funding. The United Kingdom, Germany and Sweden were also among the top five donors.
