How Sick Leave Conversion Works
Federal employees can convert unused sick leave hours into additional service credit when calculating their FERS pension. This conversion uses the official USGS conversion chart based on OPM guidelines.
- 1 work year = 2,087 hours
- 1 month = 174 hours (2,087 / 12)
- 1 day ≈ 5.8 hours (174 / 30 days per month)
- Result shows years, months, and days of additional service credit
Example: 441 hours of sick leave converts to 2 months and 16 days of additional service credit.
Important: This calculator shows how sick leave adds to your years of service for pension calculations. It does NOT show the dollar value impact - use the FERS Pension Calculator to see how this affects your pension amount.
