UNRWA is funded almost entirely by voluntary contributions. The only exception is a very limited subsidy from the Regular Budget of the United Nations, which is used exclusively for administrative costs. UNRWA's work could not be carried out without sustained contributions from state and regional governments, the European Union and other government partners, which represented 90 per cent of all contributions in 2015.
In 2015, 37 per cent of the Agency’s total pledges of US$ 1.25 billion came from EU member states, who contributed US$ 466 million, including through the European Commission. The United States and the European Commission were the largest individual donors, contributing a cumulative 41 per cent of the Agency’s overall funding. The United Kingdom, Saudi Arabia and Germany were also among the top five donors.
