Who funds international organizations?

Three ways money is counted

Where does the money go?

These are selected examples, not a complete list of U.S. payments to every organization. The table uses each organization’s reported contributions. It does not claim that all figures are cash paid in the same year.

WHO: what changed after those contributions?

On January 22, 2026, the U.S. government announced that it had completed its withdrawal from WHO. Its later fact sheet says U.S. membership, participation in governance and funding contributions ended.

The WHO row above describes 2022–2023, before that change. It should not be read as an amount the U.S. continues to give each year. WHO’s January 24 response said the withdrawal raised issues for its governing bodies to consider.

Twenty years of contributions to WFP

Every calendar year from 2005 through 2025. The same organization and donor measure are used throughout. Figures are millions of U.S. dollars at the time—not adjusted for inflation. For example, 1,000 means $1 billion.

This is a history of WFP contributions only. It is not total foreign aid or total United Nations funding. The European Commission is an EU institution, not a country.

Source: WFP annual donor tables, retrieved October 17, 2026. Each source has its own revision date. We use the first donor table’s total contributions column; “of which” amounts are already included. WFP changed its multi-year classification in 2025; the table here uses total contributions, not that subcategory. Recorded contributions can cover work over more than one year.

Read the change carefully

WFP recorded about $2.07 billion from the United States in 2025, compared with $4.45 billion in 2024. The U.S. share of WFP’s all-donor total in 2025 was about 31.7%.

A change can reflect budgets, crises, grant timing and reporting revisions. The table alone does not tell us which policy caused every rise or fall. It also does not show how many people each dollar helped.

How much development aid do other countries give?

This broader comparison includes aid delivered directly and through organizations. It is not a table of payments to international organizations alone. ODA means official development assistance: aid mainly meant to support development and well-being. Military aid is excluded. Some costs of hosting refugees inside a donor country can be included.

The OECD measures grants and the gift-like part of eligible loans. That is called a grant equivalent. It is not the same as cash sent abroad. GNI means a country’s total national income; the percentage helps compare countries of different sizes.

Released April 9, 2026. Figures are preliminary; final detailed 2025 data were scheduled for December 2026. No complete 2026 annual total is shown. This selected-country table is not a worldwide ranking. The EU’s institutional aid is excluded here to avoid adding it to member-country totals without explaining overlaps.

What about NATO?

NATO is a defense alliance. Its shared budgets pay for joint headquarters, command systems and infrastructure. A member’s spending on its own military is a separate figure; it is not a payment into NATO’s bank account.

A ceiling is a maximum allowed amount. The three listed amounts total about €5.15 billion; they need not use the full overall planning limit. Do not add that limit to the other rows.

These percentages show the agreed split of shared costs, not cash payments received and not shares of all allied military spending. All 32 members contribute under the formula.

NATO: all 32 cost shares and 2026 budgets · 2026 overall funding limit. These are budget plans, not completed 2026 spending. Euros are not U.S. dollars.

What is outside these tables?

The UN regular budget, peacekeeping, the World Bank and other development banks have separate accounts. A member’s assessed bill, an unpaid balance, a multi-year pledge and a loan should not be combined as if they were the same payment.

For more organizations, the UN system donor database reports revenue by government donor. Its accounting rules and changing organization coverage need to be checked before making a long-term comparison. The WFP history above keeps one organization consistent.
