I say ‘in Germany’ because there’s where I reside, a welfare state.
We don’t have 401K here, but public retirement systems, mandatory.
My employer also matches what I put in a small state pension system up to 50 euros. Not really much, better than nothing.
What number do I have to reach for a decent retirement? Retirement age: 67 years old.
Is it enough to save or do I have to invest?
Clearly you must invest a considerable sum (at least 1/10 of your salary) each month , government pensions will continue to decline in value. It’s probably best to spread out your savings with a diversified approach (stocks, pension fund, realty).
