The level of salary and pensions for the EUI as for all EU Institution and EU agencies is normally updated on an annual basis (unless there is an intermediate update due to high inflation), based on a non-discretionary automatic methodology comprising two elements:

a. The first element is basic salary, it represents the net evolution of purchasing power of national civil servant from a basket of 10 Member States, representing at least 75% of the EU GDP.

b. The second element - Joint Index (JI) accounts inflation in Brussels/Luxembourg. This criterion, defined as "weighting," ensures, through correction coefficients, that staff members maintain equal purchasing power regardless of their place of employment.

The sum of these two parameters determines the value of the adjustment, which has always been positive over the last 25 years, with three exceptions where salaries were reduced. The application of this method is linear and depends on the parameters provided by Eurostat.

Should the EU institutions make a corresponding positive or negative update to the remuneration and pensions of the officials and former officials of the European Union in order to rectify the value of an annual update, this same rectification shall take effect at the Institute forthwith, but may not be retroactive.

Salaries are adjusted each year by a Decision of the President on basis of the annual update of remunerations and pensions of officials and other servants of the European Union, and take effect on the dates laid down in art 2 (1) of Annex XI, in accordance with the periods of stagger set out therein.
