Members pay an annual contribution which is based on the costs that follow from the annual budget of the GPM Association. Each year, the Executive Committee summits a proposal for the amount of the annual contribution to the General Meeting. The General Meeting determines the amount of the contribution for the ongoing financial year.
The annual contribution is determined on the basis of, inter alia, the Gross National Income (GNI) and the population of the city of the member concerned, following the table below:
|Population/Gross National Income per capita||0-1,035 USD||1,03-4,085 USD||4,086-12,615 USD||12,616 USD|
