When you leave federal service, one of the biggest “wait…how much will I actually get?” questions is your federal employee leave payout. That annual leave check can be a few hundred dollars…or many thousands. The problem is most people guess, use the wrong rate, or forget taxes. Then the deposit hits and it’s not what they expected.
Here’s the good news: the math is knowable, and you can plan around it. In this guide, I’ll show you the rules, the simple formula, and real examples with dollar amounts. And if you want the easiest way to get your exact number fast, use this free tool: Annual Leave Lump Sum Calculator.
Background: What a federal leave payment really is (and isn’t)
A federal annual leave payout federal employees get at separation is called a lump-sum payment. It’s money for unused annual leave that you already earned.
A few key basics:
Annual leave vs. sick leave
- Annual leave: Paid time off you can cash out when you separate. This is what the lump sum is based on.
- Sick leave: Usually not paid out in cash. For most retirees, unused sick leave can increase your retirement service time for your annuity calculation. (Good, but different.)
OPM explains lump-sum annual leave rules here: OPM lump-sum payments fact sheet.
When you get paid
Most agencies pay the lump sum after you separate (often within 1–2 pay periods, but timing varies). It’s treated like wages, so it has tax withholding.
What rate is used
Your lump sum is based on the pay you would have received if you stayed on the rolls and used that leave. That means:
- Your hourly rate matters.
- Some pay items can count (like locality pay). Some usually do not (like per diem).
- If a pay raise happens during the period your leave would have covered, your payout can reflect it.
If you want the official rule language, start at OPM.gov and your agency HR guidance.
Carryover limits still matter
Most federal employees can carry over 240 hours of annual leave into the next leave year. Some groups (like overseas or SES) can have different limits. If you’re near retirement, carryover rules affect how much leave you can “bank” before separation.
Main Content 1: Federal employee leave payout formula (with a simple breakdown)
Let’s break the federal leave payment math into plain steps. Your agency payroll system does this, but you should still estimate it yourself.
The core formula
Annual leave lump sum = (unused annual leave hours) × (hourly rate of pay)
Then payroll subtracts:
- Federal tax withholding
- Social Security and Medicare (FICA) in most cases
- State tax (if your state has it)
- Other normal deductions may or may not apply (depends on your situation)
How to find your hourly rate
For GS employees, a quick estimate is:
- Take your annual salary (base + locality, if applicable).
- Divide by 2,087 hours (standard work hours in a year).
Example hourly rate
- GS-12 step 5 in DC locality (example salary): $115,000/year
- Hourly rate estimate: $115,000 ÷ 2,087 = $55.10/hour
Step-by-step payout example (basic)
Say you retire with 180 hours of annual leave.
- Hours: 180
- Hourly rate: $55.10
- Gross lump sum: 180 × $55.10 = $9,918
That $9,918 is before taxes.
The easiest way to get your exact number
The math gets messy fast if you have:
- A raise coming up
- A step increase
- Different localities
- Night differential or other pay rules
That’s why the annual leave lump sum calculator is so helpful. It saves time and helps you sanity-check what payroll will do.
Main Content 2: Timing strategies (retirement dates, raises, and leave year rules)
The “when” can change your annual leave payout federal employees receive. Here are the big timing issues.
Strategy 1: Separate after a pay raise (when possible)
If a general schedule pay raise starts in January, and you separate after it takes effect, your hourly rate may be higher. Since the lump sum acts like you stayed employed and used the leave, a higher rate can mean a bigger payout.
Simple comparison
- Hourly rate before raise: $50.00
- Hourly rate after raise: $51.50
- Leave hours: 240
- Difference: 240 × ($51.50 − $50.00) = 240 × $1.50 = $360 more gross
Strategy 2: Watch the leave year carryover cap
If you’re sitting on 300 hours in December and your cap is 240, you could forfeit 60 hours if you don’t use it (unless you’re in “use-or-lose” restoration situations).
If you plan to retire soon, it may make sense to:
- Schedule leave so you don’t lose hours, or
- Move your separation date so you can keep building leave without forfeiting
Strategy 3: Know what happens to benefits
Your lump sum is wages. It is not a retirement annuity payment.
If you’re retiring and keeping FEHB, read the official FEHB rules at OPM FEHB info. For TRICARE rules, start at TRICARE. For VA health care, see VA.gov.
Also, if you’re dealing with an on-the-job injury issue, OWCP rules live at DOL OWCP.
Practical Examples: Real annual leave lump sum numbers (GS and military scenarios)
These examples use round numbers so you can follow the math. Your real payout depends on your exact pay table, locality, and separation date.
Example 1: GS-9 with 120 hours of leave
- Annual pay (example): $70,000
- Hourly rate: $70,000 ÷ 2,087 = $33.55
- Leave hours: 120
- Gross payout: 120 × $33.55 = $4,026
If 22% federal withholding applies (varies), that’s about $886 withheld just for federal income tax withholding. Your actual tax bill depends on your full-year income.
Example 2: GS-13 with 240 hours (max carryover) at retirement
- Annual pay (example): $140,000
- Hourly rate: $140,000 ÷ 2,087 = $67.08
- Leave hours: 240
- Gross payout: 240 × $67.08 = $16,099
If you’re planning cash flow for the first months of retirement, that $16k gross can be a big bridge.
Example 3: “I’m separating mid-year with 60 hours and a raise hits next pay period”
Let’s say:
- Current hourly: $48.00
- New hourly next pay period: $49.20
- Leave hours: 60
If your separation date is before the raise is effective, estimate:
- 60 × $48.00 = $2,880
If you can separate after the raise (and everything else is equal):
- 60 × $49.20 = $2,952
Difference: $72. Not huge, but it’s real money.
Example 4: Military member vs. federal employee (don’t mix the rules)
Military members often ask this because they’ve heard about selling leave. The military has its own rules for selling back leave, caps, and special situations. Start with Military OneSource and Military.com for practical explainers.
If you’re a service member transitioning into a GS job, just remember:
- Military leave rules ≠ federal civilian annual leave rules.
- Your federal lump sum is based on civilian annual leave hours and civilian pay.
Example 5: Tax “surprise” example (why your net is smaller)
Say your gross lump sum is $10,000.
Possible withholdings (example only):
- Federal withholding: $2,200
- FICA (7.65%): $765
- State withholding: $400
Estimated net: $10,000 − $2,200 − $765 − $400 = $6,635
That doesn’t mean you “lost” $3,365 forever. Withholding is a prepayment. Your final tax depends on your full tax return.

Common mistakes and misconceptions (that cost people money)
Here are the big ones I see:
- Mixing up sick leave and annual leave. Sick leave usually won’t be paid out as cash.
- Forgetting the 240-hour cap. If you’re near the end of the leave year, “use-or-lose” can bite you.
- Using the wrong hourly rate. Base pay vs. base + locality can change the estimate a lot.
- Assuming the lump sum is “tax-free.” It’s wages. Expect withholding.
- Thinking the payout boosts your high-3. Your high-3 is based on your rate of basic pay, not a one-time leave payout.
For more news and real-world examples, you can also follow outlets like Federal Times, GovExec, and FedWeek. They often cover pay raises and leave-year changes.
Step-by-step: How to calculate your annual leave lump sum (and plan your date)
Use this as your checklist.
Step 1: Confirm your annual leave hours
Look in your timekeeping system or last LES.
- Use annual leave balance (not sick leave).
- Include any projected leave you’ll earn before separation, if your system shows it.
Step 2: Find your pay rate
Grab your current salary (base + locality for most GS employees). If you’re not sure, your SF-50 and pay tables can help.
Step 3: Estimate your hourly rate
- Hourly rate ≈ annual salary ÷ 2,087
Step 4: Multiply hours × hourly rate
That’s your gross federal employee leave payout.
Step 5: Estimate taxes (roughly)
Everyone’s tax situation is different, but a quick planning range helps:
- Federal withholding could be around 22% for supplemental wages in many cases
- Add 7.65% for FICA if it applies
- Add state tax if you have it
Step 6: Check timing “what ifs”
Ask:
- Is a pay raise or step increase coming soon?
- Am I at risk of forfeiting use-or-lose leave?
- Do I need the cash in a certain month?
Step 7: Use the calculator for the fast, personal answer
If you want to skip spreadsheet headaches, run your numbers through the free annual leave lump sum calculator. It’s the quickest way to see your personal estimate and test different retirement dates.
Key takeaways / Bottom Line
Your federal employee leave payout is usually your unused annual leave hours multiplied by your hourly pay rate, paid as a lump sum after you separate. The big drivers are your leave balance, your pay rate (often including locality), and your separation timing around raises and the leave-year cap.
Plan for taxes, and don’t confuse annual leave with sick leave. If you’re deciding between two retirement dates, even a small pay change can move your payout by hundreds of dollars.
