Federal Severance Pay Calculator
Updated August 2026 · Free · No sign-up
Calculate federal employee severance pay using the official OPM formula: the basic severance allowance, the age adjustment for employees over 40, and the one-year (52-week) cap — for involuntary separations and RIF.
Quick answer: Federal severance = 1 week of basic pay per year of service (first 10 years) + 2 weeks per year beyond 10, multiplied by an age factor: +2.5% for each full quarter-year of age over 40 — capped at 52 weeks total. A 48-year-old with 15 years earning $2,000/week gets about $36,000.
The OPM Severance Formula, Step by Step
Federal severance pay (5 U.S.C. 5595, administered by OPM) has three parts:
- Basic severance allowance: 1 week of basic pay per year of civilian service for the first 10 years, plus 2 weeks per year beyond 10. Partial years count in 3-month blocks (25% of a week per full quarter).
- Age adjustment: multiply by 1 + (2.5% × each full 3-month period of age over 40). At age 48 that's 32 quarters → ×1.8.
- Cap: total severance cannot exceed 52 weeks of basic pay (a career-lifetime cap — prior federal severance received counts against it).
"Basic pay" here means your rate including locality pay, but excluding bonuses, overtime, and allowances.
Worked Examples
Example 1 — mid-career RIF. Age 48, 15 years of service, $104,000 salary ($2,000/week): basic allowance = 10 + (5 × 2) = 20 weeks; age factor = 1 + (32 × 0.025) = 1.8 → 36 weeks × $2,000 = $72,000... capped check: 36 < 52 ✓ → $72,000 paid in biweekly installments.
Example 2 — young employee. Age 33, 6 years, $78,000 ($1,500/week): 6 weeks × 1.0 (no age factor under 40) = $9,000.
Example 3 — the cap in action. Age 58, 30 years, $130,000 ($2,500/week): allowance = 10 + 40 = 50 weeks; age factor 1 + (72 × 0.025) = 2.8 → 140 weeks → capped at 52 weeks = $130,000. Long-tenured 55+ employees hit the cap almost automatically — but most with 20+ years qualify for discontinued service retirement instead, which usually beats severance.
Who Qualifies (and Who Doesn't)
| Requirement | Detail |
|---|---|
| Involuntary separation | RIF, abolished position, declining relocation outside commuting area — not misconduct removals |
| 12+ months continuous service | Current continuous employment immediately before separation |
| Not retirement-eligible | If you qualify for an immediate annuity (including discontinued service retirement), severance is off the table |
| Not declining a reasonable offer | Refusing an equivalent-grade position in the commuting area forfeits severance |
| Appointment type | Career/career-conditional and similar; most temporary appointments excluded |
How Federal Severance Is Actually Paid
Not a lump sum: OPM severance pays as continued biweekly paychecks at your former rate until the entitlement runs out. Consequences worth planning around: payments stop immediately if you take another federal position; they're taxed as ordinary wages per check (normal withholding, not the 22% supplemental hit — compare with the severance tax calculator); and the biweekly drip interacts with state unemployment rules differently than a lump sum — several states delay benefits during severance weeks. Your last regular check also carries the usual items: unused annual leave pays out as a lump sum (that one does hit like a lump sum — size it with the PTO payout calculator), while sick leave converts only toward retirement, not cash.
RIF Context: Severance Is the Last Resort, Not the First
In a reduction in force, severance is what remains after the alternatives: discontinued service retirement (age 50 + 20 years, or any age + 25 years — usually better than severance), VERA/VSIP early-out and buyout offers (VSIP caps at $25,000 and, notably, replaces severance eligibility), placement programs (CTAP/ICTAP priority for other positions), and the "reasonable offer" mechanics that can relocate you instead. Order matters: accepting a $25k VSIP when your severance entitlement was $70k+ is a real and common mistake — run this calculator before signing anything in a RIF window.
Severance vs the Alternatives — Quick Comparison
| Option | Amount | Catch |
|---|---|---|
| Severance (this calculator) | Up to 52 weeks of pay, biweekly | Stops on federal re-employment; not if retirement-eligible |
| VSIP buyout | Max $25,000 lump | Waives severance; 5-year federal rehire repayment rule |
| Discontinued service retirement | Immediate annuity for life | Age/service requirements; usually beats both above |
| Unemployment (UCFE) | State-dependent weekly benefit | May be delayed during severance weeks — state rules vary |
Private-Sector Equivalent
Nothing this generous exists by right in the private sector — corporate severance is policy or negotiation, typically 1-2 weeks per year (see the standard severance calculator). The federal formula's age weighting and 52-week ceiling make it one of the strongest statutory severance schemes in the US — worth understanding precisely before any RIF decision, and worth citing if negotiating an exit from a quasi-governmental employer that mirrors OPM rules.
Frequently Asked Questions
How is federal severance pay calculated?
One week of basic pay per year for the first 10 years of service, two weeks per year after 10, multiplied by an age factor (+2.5% per quarter-year over age 40), capped at 52 weeks total.
What is the age adjustment in federal severance?
For each full 3-month period you are over age 40, the allowance grows 2.5%. Age 45 = 1.5x, age 48 = 1.8x, age 50 = 2.0x — it roughly doubles severance by the early 50s.
What is the maximum federal severance pay?
52 weeks (one year) of basic pay — a lifetime cap across your federal career; severance received in the past counts against it.
Is federal severance a lump sum?
No — it continues as biweekly paychecks at your former rate until exhausted, and stops immediately if you take another federal job.
Who is eligible for federal severance pay?
Employees involuntarily separated (RIF, abolished positions) with 12+ months of continuous service, who are not eligible for an immediate annuity and did not decline a reasonable offer.
Do I get severance if I take the VSIP buyout?
No — accepting a VSIP (max $25,000) waives severance eligibility. If your severance entitlement exceeds $25k, the buyout is usually the worse deal; compute both before signing.
Does severance stop if I get another job?
It stops only for federal re-employment. Private-sector employment does not stop federal severance payments.
Is federal severance taxable?
Yes — as ordinary wages through normal biweekly withholding (income tax + FICA), unlike private lump sums that use the 22% supplemental rate.
What counts as basic pay for severance?
Your rate of basic pay including locality adjustment, excluding overtime, bonuses, and allowances.
What happens to my annual and sick leave in a RIF?
Unused annual leave pays out as a lump sum with your final check; sick leave has no cash value but credits toward retirement if you later qualify.
