Membership Fees

All member committees and individual 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 Committee

The NC membership fee is based on the country’s Gross National Income and is calculated using 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 Country Classification.

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

G is the Gross National Income (GNI) of the country. The reference is taken from the most recent figures released by the World Bank and evaluated by the Atlas method. Please note that in the fee formula the value G should be put in as the GNI in millions of US Dollars.

The result of the expression is the fee in Euros.

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

Local Committee

The membership fee for an LC is one-third of what the fee would be for an NC in that country.

Individual Membership

The individual membership fee is 10 euros.


New committees from countries, research or higher education institutions which have not had a representative committee during the last three financial years are granted a 50 % discount in the membership fee for the financial year of their application and a 25 % discount on the following financial year.
