What comes off the gross salary

Two blocks sit between gross and net: taxes and social insurance. Taxes are borne by the employee alone, social insurance is split between employer and employee.

DeductionWho pays it
Income taxEmployee, depending on tax class and allowances
Solidarity surchargeEmployee, only above an exemption threshold
Church taxEmployee, only if a church member; rate varies by state
Health insuranceSplit evenly – including the fund-specific supplementary rate
Long-term care insuranceSplit evenly, with a surcharge for the childless and reductions from two children
Pension insuranceSplit evenly
Unemployment insuranceSplit evenly

The calculator above applies all rates as of today – the exact amounts appear in the result breakdown.

Why calculators disagree

The most common reason is the health insurance supplementary rate. Every fund sets it individually, it currently ranges from below 2% to above 4%, and it can change mid-year. Calculators that use an average are therefore systematically off. This one uses the rate of your fund as of today.

FAQ

Frequently asked questions

Taxes come off the gross salary first – income tax by tax class, plus solidarity surcharge and church tax where applicable. Then the employee shares of health, long-term care, pension and unemployment insurance. What remains is the net pay. Contribution assessment ceilings cap the social insurance side.
