Membership fees

All members except for honorary members pay an annual membership fee. The financial year of IAPS lasts from September 1st until August 31st. Please note that your payment should also cover the transaction costs.

National committees

The NC membership fee is based on the country’s Gross National Income. It is calculated by the following formula:

An equation: min(d x (75+2 x cube root of G), 400)

where d=1 for developed countries, and d=0.5 for other countries. The developed countries are defined by the latest UN WESP Classification. The result of the expression is the fee in euros.

The developed countries include: Australia, Austria, Belgium, Bulgaria, Canada, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Japan, Latvia, Lithuania, Luxembourg, Malta, Netherlands, New Zealand, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, United Kingdom and United States.

G is the Gross National Income (GNI) of the country in millions of US dollars, from the most recent World Bank figures.

If a National Committee consists of more than one country, the membership fee is based on the combined GNI of the countries.

Local committees

The membership fee for an LC is 1/3 of what the fee would be for an NC in that country.

Individual members

The individual membership fee is 10 euros.


New committees from countries or institutions which have not had a representative committee during the last 3 financial years have a 50% discount on the membership fee for the financial year of their application and a 25% discount for the following financial year.
