How it works
Enter your full-time gross salary and weekly hours, then your own hours. The calculator scales the gross salary with the hours and works out the net salary of both situations in the same way as the Germany salary after tax calculator. The result shows what you give up in gross and net pay.
Formula and worked example
Part-time gross = full-time gross × your hours ÷ full-time hours. Net pay is calculated for both.
For 30 of 40 hours on 4,000 € in tax class I:
- Gross salary at your hours: €3,000.00
- Net salary full-time: €2,605.50
- Net salary at your hours: €2,054.42
- Net salary you give up: €551.08
Frequently asked questions
How much net pay do I lose when I go part-time?
Less than the share of hours you give up. Cutting hours by 25 % lowers gross pay by 25 %, but net pay falls by less, because tax and contributions fall faster than pay.
Why does net fall by less than gross?
German income tax is progressive – the lower part of your income is taxed less. When your pay falls, the highest-taxed euros disappear first.
How is the part-time gross salary calculated?
Full-time gross salary times your hours divided by the full-time hours. For example 30 of 40 hours is 75 % of the full-time salary.
Does tax class matter?
Yes, and a change of class can matter more than the hours. The calculator uses the class you select for both salaries.
Is part-time pay below a minijob or midijob limit different?
Yes. Very low salaries fall under special rules for minijobs and the transition zone. This calculator uses the regular rules for every salary.
Does this include benefits that depend on net pay?
No. Benefits that depend on your net salary or income, such as parental allowance, are not calculated here.
