UN Budget and Funding Politics
How the United Nations is funded, why budget negotiations are intensely political, and what happens when major contributors withhold their dues.
How the UN Is Funded
The UN regular budget, which funds core operations of the Secretariat and principal organs, is approximately $3.4 billion per year, remarkably small for a global organization. It is funded through assessed contributions calculated based on each member state's capacity to pay, measured by gross national income. The United States is the largest contributor at 22 percent, followed by China at roughly 15 percent, Japan, Germany, and the UK.
Peacekeeping operations have a separate budget of roughly $6.5 billion, with a different assessment scale that places a higher burden on Security Council permanent members. The US pays about 27 percent of the peacekeeping budget. Beyond these assessed budgets, much of the UN system runs on voluntary contributions. Agencies like UNICEF, UNHCR, and UNDP depend almost entirely on voluntary donations, which creates both flexibility and vulnerability: donors can direct money to their preferred causes and withdraw funding when priorities change.
