* Avg payroll cost per employee per month = wages, wage compensation and other personnel expenses from the income statement (AOP 211: net wages, taxes and contributions on wages including the employer's, and other personnel expenses) / employees / 12. It is not an employee's gross or net salary; reporting errors can move it significantly, and values below 300€ a month are not shown. How we calculate →
Not shown: one company carries more than half of the profit or loss. The aggregate margin is not shown when fewer than 5 companies have one, or when one company carries more than half of the summed profit and loss; use the median margin and the profitable share instead. Profits that cannot be reconciled with revenue and payroll are left out.
The activity title is the code's title in the KD 2010 classification (NACE Rev. 2), which applies to every year shown. The registry now shows titles from the new classification for the same codes, so titles can differ.
