The World Health Organization (WHO) is funded by its Member States and other partners. Its two main funding sources are assessed contributions—membership dues paid by countries—and voluntary contributions from governments, UN organizations, intergovernmental organizations, philanthropic foundations, private-sector partners and other donors.
WHO funding supports its work on global health, disease prevention, emergency response, health systems and international health standards.
Assessed contributions are the mandatory membership dues that WHO Member States pay to support the organization.
The amount each country is required to contribute is calculated using an agreed assessment scale that takes factors such as national income into account. The contributions are approved by Member States through WHO's governing processes.
Assessed contributions provide a relatively predictable source of funding and help WHO plan its work. However, they have historically covered less than 20% of WHO's total budget, meaning the organization relies heavily on voluntary contributions for the rest.
Voluntary contributions are funds that donors choose to provide in addition to mandatory membership dues.
They come from sources such as:
National governments
Other UN organizations
Intergovernmental organizations
Philanthropic foundations
Private-sector organizations
Other institutional donors
Voluntary contributions make up the majority of WHO's financing. Some are flexible and can be directed toward WHO's agreed priorities, while others are earmarked for a specific programme, country or activity.
This distinction matters. Flexible contributions give WHO greater freedom to allocate resources where they are most needed, whereas earmarked donations are tied to the donor's specified purpose.
WHO funding supports a wide range of global health activities, including:
Disease surveillance and outbreak response
Vaccination and immunization programmes
Maternal and child health
Health emergency preparedness
Health-system strengthening
Research and evidence-based health guidance
International health regulations
Noncommunicable disease prevention
Health promotion and universal health coverage
Technical support to national health authorities
WHO also coordinates international responses to public health emergencies and works with governments to improve access to essential health services.
WHO is a specialized agency of the United Nations, but it has its own budget and funding structure. Its finances do not come entirely from the UN's central regular budget.
Instead, WHO receives assessed contributions from its Member States and voluntary contributions from a broad range of partners.
WHO may also receive funding for emergency activities through specific appeals or joint humanitarian financing mechanisms, depending on the crisis and programme.
The WHO Foundation is an independent grant-making foundation that mobilizes support for global health. It works with individuals, the public and corporate partners to support health initiatives.
It is legally independent from WHO, although it supports WHO's mission and global health priorities. It is one part of a much broader funding landscape, not the sole funder of the organization.
WHO's work spans nearly every area of public health, from routine technical guidance to emergency responses to outbreaks and humanitarian crises.
Voluntary funding allows donors to support particular priorities, but a heavy reliance on earmarked contributions can also make it harder for WHO to direct money toward less visible or underfunded needs.
WHO has therefore emphasized efforts to broaden its donor base and increase the predictability and flexibility of its funding.
The ranking of WHO donors changes by budget period and depends on whether the comparison covers assessed contributions, voluntary contributions or total funding. Governments and major philanthropic and institutional donors have all played important roles.
For accurate rankings, consult WHO's official contributors and funding information rather than relying on an outdated list.
WHO is funded mainly by Member State contributions and voluntary donations from governments and other partners. Assessed contributions provide a predictable base, while voluntary contributions finance most of its programmes. These resources support WHO's global health work, including disease prevention, health-system development and emergency response.
