The United Nations budget represents the financial framework approved by its Member States to support the Organization’s diverse activities, which include peacekeeping, human rights promotion, development initiatives, humanitarian aid, and political mediation. Budget discussions often expose differing views among Member States on spending priorities, administrative efficiency, and the appropriate scope of UN functions.

The UN’s budgetary debate encompasses more than just the total amount of funding. It also addresses which Member States are responsible for financing the budget, the timing of their payments, and the distinction between the budgeted amounts and the actual cash available to the organization.

According to Article 17 of the United Nations Charter, the expenses of the Organization are to be borne by Member States as apportioned by the General Assembly. However, Member States do not independently determine their contribution amounts. Instead, the General Assembly adopts a scale of assessments based on recommendations from the Committee on Contributions, which primarily considers each country’s capacity to pay.

For the 2025–2027 period, the minimum assessment rate for a Member State is set at 0.001%, while the ceiling for the least developed countries is capped at 0.01%. The overall ceiling for any single Member State’s contribution is 22%. These limits differ from those applied to fund UN peacekeeping operations, which have separate calculations and adjustments.

It is important to note that assessed contributions are considered financial obligations rather than voluntary donations. They are distinct from voluntary funding that governments may provide to specific UN programs, funds, or agencies.

The budget formulation process begins with the UN Secretary-General preparing a proposed budget. This proposal is then reviewed by the relevant committee responsible for administrative and financial matters. After negotiations and revisions, the committee forwards its recommendations to the General Assembly, which holds final authority over budget approval.

In a recent procedural change, the United Nations transitioned from a biennial budget cycle to an annual budget cycle starting in 2020, allowing for more frequent adjustments to address evolving financial needs.
