Your retirement date depends on your date of birth, the day your insurance began, your number of premium days and which insurance branch you worked under (4A SSK, 4B Bag-Kur, 4C civil servant). Instead of relying on hearsay, you can enter these details into the Social Security Institution's (SGK) own tools and see the likely date for your own situation.
In this guide we first show how to gather the details you need from your service record, then how to fill in the calculation screens on e-Devlet and on SGK's e-SGK portal. As SGK itself warns, these calculations are for information only and cannot be used in official procedures; for retirement, the Institution's records are what count.
