Calculated: How much your salary actually decreases if you reduce hours. How much salary is left if you cut hours? Whether switching to part-time is worthwhile for you personally depends on various factors - including gross salary, tax class and working hours.
A shorter hourly week usually means less salary, although the reduction is often not as significant as you might think. If you switch from a 40-year week to a 30-hour week, you would receive 25 percent less gross salary. But it doesn't mean the same for the net salary because the taxes are progressive.
