Example Scenario
Seaman Smith
  • Performed 5 days of ADT in February 2008
  • Volunteered for 180 Days of active duty service (ADOS) from 1 June 2008 to 30 November 2008
    • 127 days performed in FY 2008
    • 62 days performed in FY 2009
  • All of the active duty time performed could not be credited toward reduced retirement age eligibility because it was Active Duty Time performed under circumstances permitted under the new law (i.e., orders for voluntary service, 10 U.S.C. § 12301 (d))
  • Credited time must total 90 days or multiples of 90 days in the aggregate per fiscal year in order to correspondingly reduce his retirement age by 3 months, or multiples of 3 months
  • Reduced his retirement age by 3 months (for FY 2008)
  • If he performed 53 additional days of active service after January 28, 2008 and prior to going on active duty June 1, 2008, he would have served on Active Duty for 180 days in the aggregate in FY 2008.  This would have made him eligible to reduce his retirement age by 6 months instead of 3.
  • Served on Active Duty 61 days in FY 2009.  No early retirement adjustment.
    • Would need and additional 29 days in FY 2009 in order to reduce his retirement date by 3 months.
For FY15 NDAA and Forward, eligible service is calculated across 2 Fiscal Years.

Note: The calculation of NDAA eligibility will be conducted during the retirement (to the Gray Area) and again in the With Pay processes Only. Courtesy calculations will not be entertained.
