So it was recommended to me because I don't urgently need the money, because it just lies around in the checking account earning no interest, and because it is better off in the building savings contract.
The topic of investing money is not everyone's thing, but one should still deal with it repeatedly and critically question investments or look out for alternatives. If you use a well-known comparison portal and enter the term Tagesgeld, you will receive a risk-free "investment" at 1%. It would be even better if you could exclude fees and if this 1% is actually 1% effective. With your current investment, you will have a credit interest rate of 0.1%. 1% > 0.1%. Although this 0.1% is not really 0.1%, since you paid a connection fee of €1000 beforehand and annual account management fees of €12. You will earn more interest on your €10,000 in the Tagesgeld than on your €27,000 building savings balance. 1% of €10,000 = €100 before taxes (you might still have some of your €801 saver allowance) 0.1% of €27,000 = €27 - €12 annual fee = €15 But yes, put the money into your building savings contract.
