What Are Correction Coefficients?

EU staff salaries are set using Brussels as the reference point, where the correction coefficient is 100.0. When an EU employee works in a different location, a correction coefficient adjusts their basic salary to reflect the local cost of living.

A coefficient above 100 means the location is more expensive than Brussels — your salary is adjusted upward. A coefficient below 100 means it is cheaper — your salary is adjusted downward.

Example: If your basic salary is €5,076/month (AD 5 Step 1) and you work in Copenhagen (coefficient 127.2), your adjusted salary becomes €5,076 × 1.272 = €6,457/month. The same salary in Warsaw (coefficient 75.0) becomes €5,076 × 0.750 = €3,807/month.

The purpose is to ensure equivalent purchasing power for EU staff across all duty stations. Coefficients are proposed by Eurostat based on cost-of-living surveys and adopted annually by the Council of the European Union.

How It Works — Worked Examples

Let us take an AD 5 Step 1 official with a basic monthly salary of €5,076 and see how the correction coefficient changes their pay in different locations:

Duty Station Coefficient Adjusted Monthly Salary Difference vs Brussels
Copenhagen127.2€6,457+€1,381
Stockholm120.2€6,101+€1,025
Paris116.4€5,908+€832
Dublin115.3€5,853+€777
Brussels100.0€5,076--
Madrid96.3€4,888-€188
Lisbon89.6€4,548-€528
Warsaw75.0€3,807-€1,269
Budapest74.3€3,771-€1,305
Sofia62.5€3,173-€1,903

The difference between the highest and lowest coefficient location is €3,284 per month for the same grade and step. Over a year, that is nearly €40,000 in gross salary difference.

What the Coefficient Covers

The correction coefficient applies to the basic salary only. Other components of the remuneration package are handled differently:

  • Basic salary — Fully adjusted by the correction coefficient.
  • Expatriation allowance (16%) — Calculated on the corrected basic salary, so it is indirectly affected.
  • Household allowance — Also calculated on the corrected salary.
  • Dependent child allowance — Fixed amount, not adjusted by coefficient.
  • Education allowance — Fixed ceiling, not adjusted.
  • Pension contributions — Based on the Brussels (uncorrected) salary. This is important: your pension accrues at the Brussels rate regardless of where you work.
Pension implication: Working in a high-coefficient location (e.g., Copenhagen) means you earn more but your pension is calculated on the Brussels salary. Conversely, working in a low-coefficient location (e.g., Sofia) means lower current pay but the same pension entitlement.

Places Without a Standard Coefficient

Not all EU duty stations use the standard correction coefficient system:

EU Delegations (EEAS)

Staff posted to EU Delegations in third countries (e.g., Washington, Beijing, Nairobi) use a separate "weighting" system that also accounts for hardship, security risk, and living conditions. These weightings can be substantially higher than EU-internal coefficients.

JRC Sites

The Joint Research Centre has sites in Ispra (Italy), Karlsruhe (Germany), Geel (Belgium), Petten (Netherlands), and Seville (Spain). Each has its own specific coefficient based on the local area rather than the national capital.

Strasbourg

European Parliament staff working in Strasbourg use the French coefficient, but the cost of living in Strasbourg differs from Paris. Some staff find the Strasbourg coefficient less favourable relative to actual local costs.
