How does salary conversion affect my pension?

A salary conversion gives you less pension. Per year per 100 € that is about 1 € less pension.
(e.g. salary conversion for 3 years with 50€ per month each corresponds to 1.50€ less pension; this is offset by a higher net salary of 900€ within the 3 years)
Of course, you can compensate for this difference much more effectively by depositing into your private retirement provision.
