From my pension information:
You can assume that the calculated old-age pension of X.XXX,XX EUR will actually be higher due to future pension adjustments. However, we cannot predict the development either. Therefore, we have calculated two possible variants for you without taking inflation into account. If the annual adjustment rate is 1.5 percent, this would result in a monthly pension of Y.YYY EUR from the age of 65. With an annual adjustment rate of 2.5 percent, this would result in a monthly pension of approximately Z.ZZZ EUR.
Ehm. Sorry, but if you really dream of a 1.5 percent or 2.5 percent pension adjustment per year, then you really cannot predict the development at all ...
