  • 1.1% — your multiplier at age 62+ with 20+ years (the upgrade that doubles for some retirees)
  • 3 years — the high-3 period that defines your pension
  • 5 years — minimum continuous FEHB enrollment to keep coverage in retirement
  • 57 — the Minimum Retirement Age for anyone born 1970 or later
