The following is a question submitted by a Federal Times readers about retirement and other issues facing the federal workforce. It is answered by Reg Jones, a charter member of the senior executive service and a Federal Times columnist since 1995.<\/i><\/p>\n\n\n\n

Question<\/b>: I still didn\u2019t get my numbers corrected with OPM. They did send me their calculations but it doesn\u2019t add up to what I calculated before retirement. Also, both the annuity and FERS supplement are less than what was on my final eRetire. I sent my calculations again and my Social Security page and earnings at age 62. Their figures are much less than what is shown on the SS website for my earning at 62. Any ideas what I can do? Now, my SS page is showing an even higher number for my age 62 earnings. Will my FERS supplement be re-adjusted with that new, higher number?<\/p>\n\n\n\n

Reg\u2019s Response<\/b>: The final calculation provided by OPM will often differ from the estimate provided by your agency, though it\u2019s less common for the difference to be substantial. It\u2019s possible that some period of service your agency thought was creditable isn\u2019t or that something that was creditable didn\u2019t show up in the file received by OPM. You can ask OPM to provide you with the data and methodology they used.<\/p>\n\n\n\n
