Unused Sick Leave Isn’t Lost — It Becomes Pension
Emily A. Hall ·
Federal employees burn sick leave in their final years because they believe it disappears. Under FERS it does not disappear — it becomes pension.
How the conversion works
For FERS separations on or after January 1, 2014, employees receive credit for 100% of their unused sick leave balance in the annuity computation. Between October 28, 2009 and the end of 2013 the credit was 50%. Before that, FERS employees received no credit at all.
The balance is not paid out as cash. It converts to additional creditable service using OPM's 2,087-hour conversion chart — roughly 2,087 hours equals one year of service credit, and about 174 hours equals one month. There is no cap on how much can be credited.
What that is worth
Each additional year of service adds roughly 1% of your high-3 to your annual annuity — 1.1% if you retire at 62 or later with at least 20 years.
On a high-3 of $90,000, a year of converted sick leave is worth roughly $900 or more per year, for the rest of your life, with cost-of-living adjustments applied on top. Over a long retirement that is a meaningful sum built entirely from leave you already earned.
Two limits worth knowing
- It counts for computation, not eligibility. Sick leave cannot help you reach the years of service needed to retire in the first place. It only increases the annuity once you qualify.
- It does not affect your high-3. The conversion adds service time, not salary.
The situation where you lose it entirely
This is the part that surprises people. An employee who leaves federal service before qualifying for an immediate annuity, and takes a deferred retirement instead, generally forfeits the unused sick leave credit. It does not carry forward to the deferred annuity computation.
So an employee with 1,800 hours of sick leave who resigns short of immediate eligibility loses roughly ten months of service credit permanently. If they later return to federal service, the balance is recredited — but if they never do, it is gone.
The practical takeaway
Use sick leave when you are sick. That is what it is for, and no one should work through illness to protect a pension calculation.
But burning a large balance in your final year simply because you assume it evaporates is a costly misunderstanding. Check your balance on your leave and earnings statement, and know what it converts to before you spend it.
General education, not financial advice. Verify your balance and computation with your servicing HR office and OPM.
