About WHO

Assessed contributions

WHO’s Programme Budget is financed through a mix of assessed and voluntary contributions. Assessed contributions are the dues countries pay in order to be a member of the Organization. The amount each Member State must pay is calculated relative to the country's wealth and population.

Assessed contributions have declined as an overall percentage of the Programme Budget and have, for several years, accounted for less than one quarter of the Organization’s financing. The balance is mobilized through voluntary contributions.

However, assessed contributions remain a key source of financing for the Organization, providing a level of predictability, helping to minimize dependence on a narrow donor base, and allowing resources to be aligned to the Programme Budget.

WHO assessed contributions are due and payable as of 1 January from all WHO Member States and Associate Members (currently 194 Member States and 2 Associate Members). Where the total annual assessed contribution for a Member State is USD 200,000 or greater, that Member's contributions are assessed half in United States dollar and half in Swiss francs, otherwise, contributions are assessed in United States dollars only. WHO accepts Voluntary Supplementary Assessed Contributions (VAC).

Member States that wish to contribute to VAC are encouraged to do so and advised to make payments to the bank accounts included in the invoice indicating 'Supplementary AC' in the payment advice.
