So everything related to "Wohnriester" is very abstract... because you can only make "estimates" here.
Whether it makes sense to do a Riester? Everyone should weigh that for themselves and have it calculated.
The advantage is, of course, that you
- can deduct the contributions for tax purposes (but you can also do that with other retirement provisions!)
- you receive state subsidies
In the end, it means that you save some taxes now, which you will probably have to pay in retirement (probably less income = less taxes!).
That does make sense.
But you should also pay attention to the costs of such products... because often sales costs amount to 6-10% of the paid-in capital (i.e. of the savings contributions + state subsidies).
As an example:
max. saving amount + subsidy = €2,100 per year
in 30 years you pay in that much (incl. subsidies) €63,000
and then in the first 5 years, sales costs of €3,780-6,300 flow? That means here you are constantly in the red for the first 10 years... it has already been 10 years before you start building capital...
And sure, Wohnriester has nothing to do with a building savings contract at first, of course you can also withdraw the credit for a self-used property from other "Riesters."
HERE in this CASE it is a building savings contract, where they even reduced the building savings sum so that it is immediately ready for allocation.
So overall:
You should provide for old age! No question.
You should just calculate which makes the most sense for you personally. (And when looking at the offers, take a good look at the fine print with sales costs ;)
