See When Cooperative Share Money Pays for Itself
A Berlin housing cooperative asks for share money before it hands you a key, usually between about 800 and 3,000 euros set by floor area, and that money stays with the cooperative for as long as you live there. Put in the flat size, the cooperative’s rent and the rent you would otherwise sign, and this plots both routes across twelve years and marks the month the share money has earned itself back.

Everyone in Berlin gets told to try the Genossenschaften and nobody is told what it costs to walk in. It is not a deposit. You buy shares in the cooperative, the amount is set by the floor area of the flat rather than by what you earn, and for a normal Berlin flat that is somewhere between about 800 and 3,000 euros paid before you are handed a key. The share money then sits there. Under the older cooperatives’ rules you give two years’ notice to the end of a financial year and the settlement is worked out from that year’s balance sheet, so deciding to leave in spring means seeing the money about three years later. That is the real trade, and it is worth doing the arithmetic before you wire anything. Put in the size of the flat, what the cooperative charges per square metre, and what you would pay on the open market for the same flat, and this draws both routes across twelve years. The crossing point is the month the cheaper rent has repaid the share money. Use the rent from the listing you are actually looking at rather than the city average, because that is where the gap really opens.
