That's if you work full time. If you work on a part-time basis, you spend a proportionate amount of time working for your pension – so if you work 50%, it's half a day per week. That is still quite a lot. Pension is an important secondary employment condition. It’s also the most expensive one. Every month, your pension ‘costs’ 30.5% of your pensionable salary, of which you pay 7.5% and your employer pays 23%. Is it profitable? Yes it is, because for every euro you pay into the pension fund, you'll get 2.5 times that amount in return when you retire, for the rest of your life – even if you reach the age of 100. And if you pass away, your partner will get a pension as well. And so will your children, if you have any.
