Q.  I am a CSRS/FERS offset employee with 31 years and I have been offered the  VERA/VISP.  I would like to know how my retirement would be calculated for a VERA/VISP and how will it affect my retirement.  How do I find out what the numbers will look like for a retirement check before I decide to take the buyout?  I also have been depositing the max in my TSP account and I see that the government is not required to match it. Is it the agency you work for that decides if the government matches the TSP or not?…
