How useful is the Rürup pension?

“Primarily, everyone with a higher tax burden benefits from a Rürup-Pension, after signing the contract. This basically includes all the well-earners as well as self-employed. When choosing the monthly investment contribution, however, one should remain within the maximum deductible contribution to get the best conveying rate.
We also recommend to set fund-linked tariffs because the performance to be expected is superior to classical products.
A feature of Rürup is that they can only be paid out as as a lifelong pension without the option of capital payment.
The advantage here is the complete hedge of longevity risk (in an above-average life, the paid capital could be used up before one dies).
The Rürup is thus for many people a very lucrative and meaningful supplement or basis compared to the state pension.”
