How we calculate salaries

Short methodology and the data behind these numbers.

  1. 1We collect offersOnly vacancies from open sources where the employer states pay are used.
  2. 2We normalise themA salary range is reduced to one comparable value per vacancy.
  3. 3We compute percentilesMedian, quartiles and the average are calculated from at least 5 offers; otherwise the wider country market is shown.
  4. 4We refresh the numbersStatistics are recomputed as new vacancies appear and closed ones drop out.

Figures are pay as published by employers: taxes, bonuses and seniority inside a grade are not accounted for.
