Severance Pay Calculator

There is no federal law requiring severance pay in the US, but most companies with 100+ employees offer it as a standard practice to protect against wrongful termination claims and preserve employer reputation. The standard formula ranges from 1 week of pay per year of service (common for entry-level and hourly workers) to 3+ weeks per year (senior executives and specialized professionals). Some companies offer a flat amount regardless of tenure — typically 2–6 months of base pay — and tech companies during mass layoffs often apply a flat minimum (e.g., 16 weeks base + 2 weeks per year of tenure) that benefits short-tenured employees disproportionately.

Severance is almost always calculated on base salary only, excluding bonuses, commissions, and equity unless explicitly negotiated otherwise. Executives with employment contracts typically have pre-negotiated severance terms (often 12–24 months of total compensation) triggered by specific conditions like termination without cause or change-of-control events. The WARN Act requires 60 days advance notice for mass layoffs at companies with 100+ employees, and employers who skip that notice period typically pay 60 days of salary in lieu. Some states (including California, New York, and New Jersey) have additional notice requirements beyond the federal minimum.

Everything in a severance package is negotiable, and employers build in room to negotiate because they'd rather resolve the departure quickly and cleanly than face a lawsuit or drawn-out negotiation. The highest-leverage negotiation areas (in rough order of value) are: extending the severance period by 2–8 additional weeks, employer-paid COBRA health continuation for 3–12 months (worth $500–$2,000/month in real terms), outplacement services ($2,000–$10,000 value), stock vesting acceleration on unvested RSUs or options, favorable reference letters and rehire-eligibility commitments, and removing or narrowing non-compete and non-solicitation clauses that would limit your next job search.

Employees over 40 receive 21 days to review any severance offer under the OWBPA (Older Workers Benefit Protection Act) and 7 days after signing to revoke, which creates meaningful negotiation time. Use that window to consult an employment lawyer — a one-hour consultation ($300–$500) often uncovers $10K+ in negotiation opportunities by identifying weak points in the company's release agreement. Push back respectfully and in writing, and propose specific counter-terms rather than just asking for "more." Companies rarely walk away from a negotiation over severance because the alternative (an employment dispute) is always more expensive.

Severance pay is taxed as ordinary income in the year you receive it, and receiving a lump sum can easily push you into a higher marginal tax bracket for that year. Federal withholding on severance typically uses the 22% supplemental rate (or 37% on amounts over $1M), plus state income tax and FICA (Social Security and Medicare), meaning the actual take-home on a $50K severance is often $32K–$35K after all taxes. Importantly, the 22% withholding is often lower than your actual marginal rate, meaning you may owe additional tax at year-end — plan for that underpayment rather than being surprised at tax time.

Specific strategies reduce the tax hit: ask about spreading payments across two tax years (receiving half in December and half in January keeps you in lower brackets), contribute the maximum to a traditional 401(k) before the termination date to offset the income spike, or negotiate for non-taxable benefits (employer-paid COBRA, outplacement services) instead of additional cash since these provide real value without tax liability. If you're near Medicare eligibility (age 65), also consider how severance affects IRMAA Medicare premium surcharges two years later — a large one-year income spike can trigger higher Medicare Part B and Part D premiums in the year you actually enroll.
