Assessed contributions
Assessed contributions (AC) are the amounts each of the 196 Members and Associate Members must pay to WHO on an annual basis. The assessment scale is calculated by the United Nations based mainly on the country’s GDP and is adjusted for WHO’s membership. It is approved every two years by the World Health Assembly (refer to the latest approved assessment scale resolution attached here).
Assessed contributions are a key source of financing for the Organization, providing predictable financing, helping to minimize the dependence on a narrow donor base, and allowing resources to be aligned to the Programme Budget. Assessed contributions have declined as an overall percentage of the Programme Budget and have, for several years, accounted for less than 20% of the Organization’s financing. The balance is mobilized through voluntary contributions.
