Error in financing?

Maybe do it or alternatively take a longer fixed term of up to 30 years.

I have now simply put the cart before the horse. With a loan of 405,000.- and a constant payment of 1,253.-, I get an interest rate of 0.73% over the entire term for a duration of 30 years (remaining debt = 0). So something must be wrong, which your feeling tells you immediately...

where did you get this bill from, that would be nice Unfortunately, it doesn't even work with €1,500

google search credit calculator and then the link Zinsen-berechnen... You can calculate everything there, possible loan amount, interest, installment, term, etc...

yes...oh no...I already understand that. In this case, it is about the concrete construct with concrete values described above...

Actually, the topic is totally simple in terms of calculation, but every financial service provider makes a huge science out of it and I don't understand that in return.

15 years fixed with a lot of repayment and then a large uncertain amount is not an option, as I want as much interest rate security as possible and now want to know what I would have to pay in the worst case.

if it’s simple, then calculate it yourself.... hm
