Boy that seems low if she hits her rule of 88, years of service + age = 88. You are penalized for retiring before you hit your rule of 88. So say you only taught 25 years but want to retire at 55, the earliest you can under IPERS, then she would pay a penalty for those years that she was under 30 years. You can log on to the IPERS website and it will show you how much penalty it is for each year. I think it was around 6.0% per year under 30.
They also have a rule of 20 + 62 = a full pension.
There should be a total buyout listed on the top of the 3rd page I think it was.
My statement said if had retired in May, I would be at 89, and would receive right at $2890 a month,.If I chose option one. I have 31 years in and I am 58. The most I ever made teaching was right at 60K for a year.
