The United Nations’ financing system continues to depend heavily on contributions from a relatively small group of major economies, with the United States carrying the largest assessed share of the organization’s regular budget in 2026.

The current assessment places the U.S. contribution at approximately 22% of the UN regular budget. China follows with around 20%, while Japan and Germany account for approximately 6.9% and 5.6%, respectively.

These figures reflect the UN’s system for allocating regular-budget assessments among member states according to their relative capacity to pay.

How UN Contributions Are Determined

The UN does not divide its regular budget equally among all member states.

A country’s assessment is calculated using a formula that considers factors including national income and other economic indicators. This means larger economies generally carry a greater share of the organization’s assessed financial obligations.

The scale is periodically reviewed and adjusted as countries’ economic circumstances change.

United States Has the Largest Assessment

The United States remains the largest single contributor to the UN’s regular budget.

Its approximately 22% assessment means that developments in U.S. funding policy can have significant implications for the organization’s overall financial position.

China’s share has also become increasingly significant as its economy has expanded and its assessed contribution has risen over successive assessment periods.

Other Major Economies Also Contribute

Japan, Germany and other major economies make substantial contributions to the UN system.

Japan’s regular-budget assessment is approximately 6.9%, while Germany’s share is about 5.6%.

Together with other major contributors, these countries provide a significant portion of the resources used to operate the UN’s core activities.

Peacekeeping Uses a Different Scale

UN peacekeeping operations have a separate financing system.

The assessment for peacekeeping is generally higher for the largest economies than their regular-budget percentages. The United States’ peacekeeping assessment is approximately 26%.

The different scale reflects the special financing arrangements used for UN peacekeeping operations.

Where the Money Is Used

The UN regular budget supports the organization’s core functions, including international diplomacy, political affairs, development-related work, human-rights activities and administrative operations.

Peacekeeping contributions, meanwhile, help finance missions established by the UN to support international peace and security.

The availability of predictable funding is important for maintaining these activities.

Financial Pressure on the Organization

The UN has faced financial pressures when member states delay or reduce payments.

Delayed contributions can affect cash flow and make it more difficult for the organization to meet operational expenses on schedule.

As a result, member-state contributions remain a central issue in discussions about the UN’s financial sustainability.

Changing Global Economy

The distribution of financial responsibility also reflects changes in the global economic landscape.

As economies grow or decline relative to one another, their assessed shares can change. China’s rising contribution, for example, reflects its increased weight in the global economy.

The contribution system therefore evolves alongside changes in international economic power.

Importance of Predictable Funding

For the UN, predictable contributions allow agencies and departments to plan programs, maintain staff and meet operational commitments.

Stable financing is particularly important for activities that require long-term planning, including peacekeeping and international development programs.

The 2026 assessment figures highlight how closely the organization’s financial structure remains connected to the economic strength of its member states.
