Organizational Chart

Financing the United Nations

The budget covers the costs of United Nations programmes in areas such as political affairs, international justice and law, international cooperation for development, public information, human rights and humanitarian affairs.

The main source of funds for the regular budget is the contributions of member states. The scale of assessments is based is the capacity of countries to pay. This is determined by considering their relative shares of total gross national product, adjusted to take into account a number of factors, including their per capita incomes.

In addition to the regular budget, member states are assessed for the costs of the international tribunals and, in accordance with a modified version of the basic scale, for the costs of peacekeeping operations.
