Federal Employee Severance Pay Calculator (2026)
If you are facing a Reduction in Force (RIF) or other involuntary separation, you may be entitled to severance pay under 5 U.S.C. § 5595. Federal severance pay is calculated using a formula that gives more weight to longer service and older employees — but it is capped at 52 weeks of basic pay over your lifetime and is terminated if you are reemployed by the federal government before it runs out. This calculator shows your basic severance allowance, your age adjustment, total severance pay, and the biweekly payment schedule.
Not eligible for severance: employees who accept VERA, VSIP, or who resign voluntarily; employees on temporary or term appointments; employees who decline a reasonable offer of another position.
How federal severance pay is calculated
Federal severance pay under 5 U.S.C. § 5595 is computed in two steps: a basic severance allowance and an age adjustment.1
Step 1: Basic severance allowance
Count your full years of creditable civilian service, plus any full 3-month periods beyond your last full year:
- First 10 years of service: 1 week of basic pay per year (and 25% of 1 week per full quarter beyond the final full year).
- Service beyond 10 years: 2 weeks of basic pay per year (and 25% of 2 weeks per full quarter beyond the final full year).
- Example: 22 years and 7 months = 10 × 1 week + 12 × 2 weeks + 2 quarters × 0.5 week = 35 weeks basic allowance.
Step 2: Age adjustment factor
For every full 3-month period you are older than 40, add 2.5% of your basic allowance. This rewards longer-tenured, older employees who face a harder job market.
- Age 45 → 20 full quarters over 40 → 50% increase
- Age 50 → 40 full quarters over 40 → 100% increase (doubles the basic)
- Age 55 → 60 full quarters over 40 → 150% increase
- Age 60 → 80 full quarters over 40 → 200% increase (but the 52-week cap usually applies here)
Lifetime 52-week cap
The total severance you can receive over your entire federal career — across all separations — is capped at 52 weeks of basic pay.2 For a $120,000 employee, that cap is $120,000. If you previously received severance pay, that amount is deducted from your remaining lifetime balance.
How severance pay is paid
Unlike a VSIP buyout, federal severance is not a lump sum. It is paid bi-weekly, at your regular pay rate, as if you were still on payroll — except that you are no longer employed. Each bi-weekly payment continues until your total severance is exhausted.
Critical rule: recoupment on reemployment. If you are reemployed by a federal agency covered by 5 U.S.C. § 5595 while receiving severance pay, your payments stop immediately. When you leave that position again, you get the remainder of your original severance balance — your lifetime cap is not reset. If you are reemployed by a non-covered employer (state government, private sector, contractor), severance continues uninterrupted.
Severance is subject to:
- Federal income tax withholding (based on your W-4, same as regular wages)
- Social Security tax (6.2% up to the 2026 wage base of $184,500)3
- Medicare tax (1.45%, plus 0.9% Additional Medicare Tax if income exceeds $200,000 single/$250,000 MFJ)
FERS retirement contributions are NOT deducted from severance — you have already separated from service.
Severance pay vs. retirement: which should you take?
If you are facing a RIF and you are also eligible for an immediate retirement, you have a critical choice to make. You cannot receive both severance pay and a FERS annuity simultaneously for the same separation. OPM will terminate severance if you are also eligible for and elect an immediate retirement.
| If you are... | Typically better option | Why |
|---|---|---|
| Age 55+ with 20+ years (VERA eligible) | Retirement | Lifetime annuity + FEHB continuation + FERS supplement (if at MRA+20) far exceeds 52 weeks of severance. See the VERA/VSIP Calculator. |
| Age 60+ with 20+ years (immediate retirement) | Retirement | Immediate unreduced annuity + FEHB from day one. Severance is a lump-stream of ~$50-100K; annuity is $40,000-$100,000 per year forever. |
| Age 50-54, not VERA eligible, under MRA+10 | Severance | No immediate retirement option. Severance buys time. Consider MRA+10 deferred retirement as a future backstop — see MRA+10 Guide. |
| Under 10 years of service | Severance (if eligible) | Severance provides immediate income. FERS vesting is 5 years for a deferred annuity at 62 — modest for short-service employees. |
The key question: can you get an immediate retirement? If yes, use the FERS Retirement Calculator to compare your lifetime annuity value against your capped severance total. For most career federal employees near retirement age, the annuity wins decisively.
What severance pay does NOT include
- Annual leave lump sum: You receive your unused annual leave balance as a separate lump-sum payment. This is in addition to severance pay, not part of it. The annual leave payout is ordinary income (wages), subject to FICA. Use the Annual Leave Payout Calculator to estimate this amount.
- TSP balance: Your TSP stays yours. You may leave it in TSP, roll it to an IRA, or take distributions. If you separate at age 55 or older, the Rule of 55 allows penalty-free TSP withdrawals. See the TSP Rollover vs. IRA Guide.
- FEHB continuation: FEHB ends when your employment ends. You can continue coverage for 18 months under Temporary Continuation of Coverage (TCC) at 102% of the full premium, or enroll in an ACA marketplace plan. If you later accept VERA, FEHB continues under the retirement rules (5-year rule).

Model your full RIF scenario with a specialist
Severance pay is one piece of a RIF decision. The calculator can't integrate your full picture: your specific retirement eligibility date, annual leave balance, TSP balance and Rule of 55 timing, FEHB 5-year rule status, any deferred retirement option, and whether you have a private-sector opportunity. A federal benefits specialist can model the full scenario and help you decide whether to accept separation, contest it, or request a different position offer.
