Scale of Assessments

The Scale of Assessments is the schedule by which the United Nations General Assembly distributes financial responsibility for the regular budget across its 193 member states. Its legal foundation lies in Article 17, paragraph 2 of the UN Charter, which provides that "the expenses of the Organization shall be borne by the Members as apportioned by the General Assembly." The guiding principle — capacity to pay — was articulated by the Assembly in resolution 14(I) of 1946 and has been reaffirmed in every triennial review since. The Committee on Contributions, a body of 18 experts established under General Assembly resolution 14(I) and now governed by rules 158–160 of the Assembly's Rules of Procedure, recommends the scale to the Fifth Committee (Administrative and Budgetary), which negotiates the final figures for plenary adoption.

The methodology proceeds in defined steps. The Committee on Contributions begins with each member's Gross National Income (GNI) averaged over a base period — currently six and three years, with the two averages then themselves averaged to smooth volatility. GNI figures are converted to United States dollars using market exchange rates, with Price-Adjusted Rates of Exchange (PAREs) substituted where market rates produce excessive distortion. From this raw share, two adjustments are applied: a debt-burden adjustment, which deducts a portion of external debt stock, and a low per capita income adjustment, which reallocates assessments downward for states whose per capita GNI falls below a defined threshold (calibrated to the world average per capita GNI), with a gradient coefficient of 80 percent. The resulting shares are then bounded by a ceiling of 22 percent (held by the United States since 2000) and a floor of 0.001 percent, with a separate ceiling of 0.01 percent for least developed countries.

The scale is fixed triennially. The current scale, adopted by resolution 76/238 of December 2021, governs assessments for 2022–2024; its successor was negotiated in the autumn 2024 session of the Fifth Committee for the 2025–2027 period. Separate but related scales apply to the peacekeeping budget — derived from the regular scale but with surcharges imposed on the five permanent members of the Security Council (Levels A and B under resolution 55/235 of 2000, as periodically updated) and discounts granted to developing states grouped into Levels C through J. International tribunals, the capital master plan, and the Working Capital Fund are assessed on the regular scale; specialized agencies such as WHO, ILO, and UNESCO maintain their own scales derived from but not identical to the UN's.

In practice the scale produces concentrated dependency. For 2022–2024 the United States is assessed at the ceiling of 22 percent; China at approximately 15.25 percent, having overtaken Japan during the previous scale; Japan at roughly 8 percent; Germany at about 6 percent; and the United Kingdom and France each near 4.4 percent. Together the top ten contributors fund more than 67 percent of the regular budget. The Fifth Committee negotiations in New York — led traditionally by the Group of 77 and China, the European Union, JUSCANZ (Japan, United States, Canada, Australia, New Zealand), and CANZ subgroups — routinely run past their December deadline, with the 2021 round concluding only on 24 December after disputes over the low per capita income adjustment's gradient and the treatment of Venezuela's GNI data.

The Scale of Assessments must be distinguished from voluntary contributions, which fund UNHCR, UNICEF, WFP, and most operational activities and which are not governed by Article 17 at all. It is also distinct from the peacekeeping scale, which applies surcharges and discounts unavailable in the regular scale, and from arrears, which are governed by Article 19 of the Charter (loss of vote in the General Assembly when arrears equal or exceed assessed contributions due for the preceding two full years). The scale determines what is owed; Article 19 determines the consequence of nonpayment.

Controversies recur. The United States Congress has repeatedly capped its peacekeeping contribution below the assessed rate — most notably under the Helms-Biden agreement of 1999 and subsequent National Defense Authorization Acts — generating chronic arrears that triggered Article 19 procedures in 1999. China's rapid ascent up the scale, from 1.5 percent in 2000 to over 15 percent today, has shifted the political center of gravity within the Fifth Committee. Member states with collapsed currencies or sanctioned economies — Venezuela, Syria, Afghanistan since 2021 — present recurring methodological problems for the Committee on Contributions in selecting reliable GNI data. Proposals to raise the ceiling above 22 percent, lower the floor, or revise the debt-burden adjustment surface in every triennial review and are routinely deferred.

For the practitioner, the Scale of Assessments is the financial architecture beneath every multilateral initiative pursued in New York. A mission planning a Security Council-mandated operation, a desk officer drafting talking points for ECOSOC, or a researcher tracking institutional reform must understand that budgetary leverage is unevenly distributed and procedurally constrained: the United States cannot unilaterally reduce its assessment, but it can withhold payment; the G-77 cannot raise the ceiling, but it can block scale adoption. Mastery of the scale's mechanics — base periods, conversion rates, adjustment gradients, ceiling and floor — is indispensable for anyone negotiating in the Fifth Committee or interpreting Secretariat budget proposals.
