How severance is usually calculated
Severance has no statutory formula — but corporate America has converged on one:
Severance = (years of service) × (weeks of pay per year) × (weekly pay)
The typical inputs:
- Weeks per year of service: 1–2 is standard; 4+ is generous; executives often get months-per-year instead of weeks.
- Caps: many plans cap total severance (26 weeks is a common ceiling) no matter how long you served.
- Minimums: some plans guarantee 2–4 weeks even for short-tenured employees.
- Tenure credit: usually counts completed years; some plans prorate partial years.
On top of the base formula, a real package usually includes unused PTO payout (where required) and continued benefits — most often the employer keeps paying its share of your health premiums for a few months instead of cutting you to COBRA immediately.
Worked example: $104,000 salary, 5 years, 2 weeks/year
| Component | Math | Amount |
|---|---|---|
| Weekly pay | $104,000 ÷ 52 | $2,000 |
| Severance weeks | 5 yrs × 2 wks/yr = 10 (under 26-wk cap) | 10 wks |
| Base severance | 10 × $2,000 | $20,000 |
| Unused PTO (40 hrs at $50/hr) | 40 × $50 | $2,000 |
| Continued health benefits (3 mo × $800) | 3 × $800 | $2,400 |
| Total package value | $24,400 | |
| Est. federal withholding on severance (22%) | $20,000 × 22% | $4,400 |
The $4,400 withholding is not the final tax — it's the supplemental-wage withholding your employer applies. Your return reconciles it at your actual marginal rate.
What moves the number
- Tenure. The formula is linear in years — but caps blunt it. Twenty years at 2 weeks/year is 40 weeks on paper, 26 under a typical cap.
- The multiplier. The difference between 1 and 2 weeks per year doubles everything. This is the single most negotiated term.
- The cap. Always ask what the cap is before doing the math — it's where long-tenured employees lose the most.
- Benefits continuation. Three months of employer-paid premiums at $800/month is $2,400 of real value most people forget to count. COBRA without it runs $600–$800+/month for single coverage.
- What's excluded. Final paycheck wages, earned bonuses, and vested retirement money are yours already — they're not severance, and shouldn't be framed as generosity.
Negotiation levers beyond the formula
Severance agreements are contracts, and contracts are negotiable — especially before you sign the release:
- More weeks. Ask. The worst answer is no, and employers often have 10–20% of flex.
- Extended benefits. Pushing employer-paid health coverage from 3 to 6 months can be worth thousands.
- Outplacement services. Career coaching is cheap for them, valuable for you.
- Reference terms. Get the neutral-reference language in writing.
- Non-compete scope. If the agreement includes or extends a non-compete, that's worth real money — price it accordingly.
- The 21-day clock. If you're over 40, federal law (OWBPA) gives you 21 days to consider and 7 days to revoke after signing. Use them.
Tax treatment in one paragraph
Severance is supplemental wages (IRS Publication 15, 2026): 22% federal withholding on the standard portion, full FICA (6.2% Social Security to the $184,500 wage base, 1.45% Medicare), state withholding per your state's supplemental rate, and 37% federal on cumulative supplemental wages over $1M/year. A large lump sum can also push you into a higher marginal bracket for the year — another reason the withholding and the final liability differ.

Data sources
- WARN Act: 29 U.S.C. §§2101–2109 — 60 days' notice for covered mass layoffs/plant closings (employers with 100+ employees).
- OWBPA: Older Workers Benefit Protection Act — 21-day consideration / 7-day revocation for workers 40+.
- Tax: IRS Publication 15 (2026), supplemental wages; SSA 2026 FICA figures.
- Formula conventions: 1–2 weeks/year with caps reflects standard US employer practice (no single statutory source — practices vary).
Frequently asked questions
Is my employer legally required to pay severance?
Generally no. No federal law requires severance pay — it's a matter of company policy, employment contract, or negotiation. The exception is the federal WARN Act, which requires 60 days' written notice (or pay in lieu) for mass layoffs and plant closings at employers with 100+ employees, but that's notice, not a severance formula.
What is a typical severance formula?
The most common formula is 1–2 weeks of pay per year of service, often with a cap (e.g., 26 weeks) and sometimes a minimum (e.g., 2–4 weeks regardless of tenure). Executives and long-tenured employees often negotiate more. There is no standard — everything about severance is negotiable until you sign the release.
How is severance taxed?
Severance is supplemental wages: employers typically withhold federal tax at the flat 22% rate (37% on cumulative supplemental wages over $1M/year, per IRS Publication 15, 2026), plus full FICA and state withholding. Your actual tax is settled at filing — the 22% is withholding, not your final rate.
Lump sum or salary continuation — which is better?
A lump sum gives you cash now and a clean break; salary continuation keeps you on payroll (and usually on the health plan) longer, which can delay COBRA costs and sometimes extends the tenure used for vesting. Tax-wise they're similar. Continuation can complicate unemployment benefits in some states, since you're technically still employed.
Should I sign the severance agreement right away?
Don't rush. Agreements almost always include a release of legal claims, and workers over 40 get special protections (the Older Workers Benefit Protection Act requires 21 days to consider and 7 days to revoke). Use the time to negotiate: extra weeks, extended benefits, outplacement help, and a neutral reference are all commonly granted.
Does severance affect unemployment benefits?
It depends on the state and the payment structure. Some states reduce unemployment benefits by severance amounts; others don't count lump-sum severance at all. Check your state unemployment agency's rules before assuming either way.
