Choosing the right retirement date

Eligibility is not only about reaching a minimum age. Federal retirement timing requires alignment between age, service credit, and special provisions that may apply to your position. Use this tool to identify your earliest date, then test nearby dates to understand the tradeoff between leaving sooner and locking in a larger annuity.

  • Check special category service flags if you are LEO, firefighter, or air traffic controller.
  • Compare dates around birthdays and service anniversaries because thresholds can change outcomes.
  • Use the result as a planning anchor, then validate in your full annuity projection workflow.

Frequently asked questions

Can I retire as soon as I become eligible?

In many cases yes, but the financially optimal date may be later depending on service milestones and pension multipliers.

What if my agency records differ?

Always reconcile discrepancies with your HR office and official service history before making final decisions.
