What is Federal Use or Lose Leave?
“Use or lose” annual leave is the amount of accrued annual leave that is over an employee’s maximum carryover limit at the end of the leave year. For most federal employees working within the United States, the maximum amount of annual leave they can carry over from one leave year to the next is 240 hours. Any leave balance above this 240-hour ceiling is forfeited if not used by the final day of the leave year.
The policy exists to encourage employees to take regular vacations and avoid excessive leave accumulation. The leave year for federal employees begins on the first day of the first full biweekly pay period in a calendar year and ends on the day right before the first day of the first full biweekly pay period in the following calendar year. It’s crucial for employees nearing the 240-hour limit to plan and use their excess leave to prevent forfeiture. This federal use or lose leave calculator helps you forecast your balance precisely.
The Formula for Calculating Use or Lose Leave
The calculation is straightforward. It involves your current leave balance, the leave you’ll earn for the rest of the year, the leave you plan to take, and your maximum carryover ceiling.
Use or Lose Hours = (Current Balance + Future Accruals – Planned Leave) – Leave Ceiling
If the result is a positive number, that’s the number of hours you stand to lose. If it’s zero or negative, you are safely under the carryover limit.
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Current Balance | Your current annual leave balance. | Hours | 0 – 400+ |
| Future Accruals | Total leave earned for the rest of the year (Rate x Remaining Pay Periods). | Hours | 0 – 208 |
| Planned Leave | Annual leave you have scheduled or plan to use. | Hours | 0 – 400+ |
| Leave Ceiling | Maximum hours you can carry over. | Hours | 240 (standard), 360, 720 |
Practical Examples
Example 1: Mid-Career Employee
An employee with 10 years of service is approaching the end of the leave year.
- Inputs:
- Current Leave Balance: 230 hours
- Leave Accrual Rate: 6 hours (3-15 years service)
- Remaining Pay Periods: 4
- Planned Leave: 16 hours
- Leave Ceiling: 240 hours
- Calculation:
- Future Accruals: 4 pay periods * 6 hours/pp = 24 hours
- Projected End Balance: 230 + 24 – 16 = 238 hours
- Use or Lose Hours: 238 – 240 = -2 hours
- Result: The employee will have 0 use or lose hours and will carry over 238 hours.
Example 2: Senior Employee with High Balance
A senior employee with over 20 years of service has not taken much vacation.
- Inputs:
- Current Leave Balance: 280 hours
- Leave Accrual Rate: 8 hours (15+ years service)
- Remaining Pay Periods: 3
- Planned Leave: 24 hours
- Leave Ceiling: 240 hours
- Calculation:
- Future Accruals: 3 pay periods * 8 hours/pp = 24 hours
- Projected End Balance: 280 + 24 – 24 = 280 hours
- Use or Lose Hours: 280 – 240 = 40 hours
- Result: The employee must use an additional 40 hours of leave to avoid forfeiture.

Key Factors That Affect Use or Lose Leave
- Years of Service: Your length of service directly impacts your accrual rate, determining how quickly you accumulate leave.
- Leave Planning: Proactively scheduling and using leave throughout the year is the most effective way to avoid forfeiture.
- Leave Year End Date: The leave year does not align perfectly with the calendar year. Knowing the exact end date is crucial for last-minute leave usage.
- Special Leave Ceilings: Certain employees, like those in the Senior Executive Service (SES) or those serving overseas, have higher carryover limits (e.g., 720 or 360 hours).
- Restored Leave: In some situations, such as an exigency of public business, forfeited leave can be restored, but this requires that the leave was scheduled in writing well in advance.
- Leave Without Pay (LWOP): Taking extended LWOP can affect your leave accrual for a given pay period, slightly altering your year-end total.
Frequently Asked Questions (FAQ)
What is the maximum annual leave I can carry over?
For most federal employees in the U.S., the maximum is 240 hours. This can be higher for certain groups like overseas employees (up to 360 hours) or SES members (up to 720 hours).
When does the federal leave year end?
It ends on the day immediately before the first day of the first full biweekly pay period of the next calendar year. This date changes annually. For example, in 2024 it might end in early January 2025.
What happens if I forfeit my leave?
The leave is permanently lost unless you qualify for leave restoration. Restoration is typically only granted if you were unable to take scheduled leave due to an urgent need of public business or sickness.
Does sick leave count towards the “use or lose” limit?
No. Sick leave is separate from annual leave. There is no limit to how much sick leave you can accumulate and carry over from year to year.
Can I get a cash payout for my use or lose hours?
No. You cannot receive a lump-sum payment for excess annual leave that you forfeit at the end of the year. Payouts for annual leave are only made when you separate from federal service.
How is the accrual rate for part-time employees calculated?
Part-time employees earn leave on a prorated basis. For example, an employee with less than 3 years of service earns 1 hour of annual leave for every 20 hours in a pay status.
Does military service count towards my leave accrual rate?
Yes, for non-retired members, full credit for honorable uniformed service is generally given for the purpose of determining your annual leave accrual rate.
What if I scheduled my leave but it was cancelled by my supervisor?
If you scheduled your leave in writing before the deadline (typically three pay periods before the end of the leave year) and it was cancelled due to an exigency of business, you can apply to have the forfeited leave restored.
