If you're on AFPS75 then the maximum pension you can earn is 37 years -
B Word,
I'm on AFPS75 and just tried the pension calculator on the basis of working until 60. The maximum level of pension it came up with was to a limit of 34 years. Where did you get the 37 number from?
Also noted the 2nd IBN which gives 28 days for individuals to decide if they wish to extend their career, for those in the first batch. If 28 days is the norm for everyone else to decide whether to extend, that is one hell of a short timescale to make a decision when there are still so many unknowns with items like pensions!
