• Basic Monthly Salary Range: Statutory monthly basic pay for Assistants in grade AST 3 ranges from €4,806.17 (Step 1) to €5,437.91 (Step 5).
• Take-Home Remuneration Exceeds Base Pay: Expatriation (16%) and family allowances routinely increase net take-home pay to between €3,818 and €6,297 per month in Brussels.
• Automatic Seniority Progression: Officials advance automatically by one step every two years under Article 44 of the Staff Regulations, while advancement to AST 4 occurs via the annual promotion exercise.
• Purchasing Power Indexing: Your net earnings are adjusted by local Correction Coefficients, ranging from 66.1% in Sofia to 130.7% in Dublin relative to Brussels.

Assistants in grade AST 3 carry out technical, administrative, financial, and project management responsibilities across all 79 European Union institutions, bodies, and decentralized agencies.

Your total monthly compensation as an AST 3 assistant is determined by three factors: your seniority step (1 through 5), your personal family situation, and your duty station. Under the official salary scales established in Article 66 of the Staff Regulations, basic monthly gross pay begins at €4,806.17 for entry-level AST 3 Step 1 and rises to €5,437.91 at Step 5. On top of base pay, eligible staff can receive several statutory allowances, including expatriation allowance (16%), household allowance, and dependent child allowances (€527.06 per child).

This guide provides the official salary scale for AST 3 assistants, a detailed breakdown of statutory allowances and deductions, sample net pay calculations for typical Brussels scenarios, and the basic pay calculations according to country-by-country Correction Coefficients.

Basic salary vs. full remuneration package

A frequent mistake among candidates applying for EPSO assistant competitions is confusing nominal basic salary with final net bank deposits. Basic monthly salary acts solely as the statutory calculation baseline before compulsory additions and deductions are applied.

Depending on whether you qualify for the expatriation allowance and family benefits, your net salary can range from roughly 80% to over 130% of your nominal basic pay. Furthermore, staff stationed outside Brussels or Luxembourg have their pay weighted by an official purchasing power index called the Correction Coefficient.

Unlike Contract Agents, permanent officials (fonctionnaires) enjoy statutory tenure under the Staff Regulations and do not pay unemployment insurance contributions.

Official Salary Scale for Assistants AST 3 (Compared to AST 1–AST 5)

Under Article 66 of the Staff Regulations, basic monthly salaries are uniform across all EU institutions.

The table below sets out the official monthly basic gross salary scale for AST grades 1 through 5 across all five steps:

Allowances and Benefits

Staff of EU institutions can be entitled to several allowances and other benefits:

• Expatriation Allowance (16%): Granted under Article 4 of Annex VII to staff who are not nationals of the host country and have not resided or carried out their main work there during the five years prior to recruitment. It equals 16% of the total of basic salary plus household allowance and dependent child allowance (with a statutory minimum of €714.89 per month).
• Foreign Residence Allowance (4%): Granted if you do not qualify for the full expatriation allowance but lived or worked outside your country of origin.
• Household Allowance: Calculated as a flat amount of €241.21 plus 2% of basic salary for married staff, registered civil partners, or single staff with dependent children.
• Dependent Child Allowance: A flat rate of €527.06 per month per child, payable up to age 18 (or up to age 26 if in full-time education or vocational training).
• Education Allowance & European Schooling: Children of EU staff are guaranteed free enrollment in a European School, or receive an education allowance where no European School is located near the duty station.
• Annual Travel Grant: A flat-rate annual allowance based on the geographical distance between your duty station and your recognised place of origin.
• Installation and Daily Subsistence Allowances: Newly recruited staff relocating to take up duties receive a daily subsistence allowance during probation, plus an installation allowance of one to two months’ basic salary upon settling.

Sample Calculations: AST 3 Step 1 Net Take-Home Pay

Most new staff will enter EU institutions at grade AST 3 start at Step 1, where the gross basic salary is €4,806.17. However, this is not your take-home pay.

Below is a breakdown of estimated monthly net take-home pay across four standard scenarios in Brussels (without an applied Correction Coefficient):

Impact of the Correction Coefficient Across EU Duty Stations

To guarantee equal purchasing power across the European Union, basic salaries and allowances are adjusted by a statutory Correction Coefficient under Article 64 of the Staff Regulations. Brussels and Luxembourg serve as the reference base at 100.0%.

The table below illustrates how the nominal basic pay of an AST 3 Step 1 (€4,806.17) is adjusted across major EU duty stations, including EU agency headquarters:
