Gross is not the same as net

In Germany when you sign a work contract for employment subject to social security contributions, your contract states your gross salary. But gross is not the same as net. It means that you will receive less than what is stated in your work contract. 

For example: in 2015, the average gross salary for all salary categories together for men was just under 4,400 euros a month. Women, who tend to work more part-time and in service professions where pay low, earned an average 3,500 euros a month. In the case of employees in jobs subject to social security contributions, employers automatically deduct income tax, the “solidarity surcharge” (Solidaritätszuschlag) and the statutory social security contributions. The advantage is that your social security contributions mean that you are financially insured if you lose your job, fall ill, or are in need of care, and in old age. The employers even take over some costs. The amounts deducted may vary depending on your income, federal state, tax bracket, health insurance fund and family status. In 2015, an unmarried woman or unmarried man in tax bracket I in the western German states received an average net salary of 2,166 euros or 2,596 euros respectively.
