Severance Pay Estimator

Severance pay is one of those employment topics that most workers understand vaguely until the day it becomes urgently relevant — which is exactly the wrong time to learn that what you thought was standard is actually discretionary, what you thought was negotiable was already the maximum, and what you thought was taxed lightly is ordinary income subject to your full marginal rate. Understanding how severance is calculated, what affects the amount, how it's taxed, and what you might be able to negotiate before or at termination gives you significantly more control over the financial transition than most departing employees exercise.

The Severance Agreement and the Release

Employers typically require you to sign a separation agreement — including a release of all legal claims against the employer — before paying severance. This release means you're agreeing not to sue for wrongful termination, discrimination, wage theft, or other employment claims in exchange for the severance payment. The ADEA (Age Discrimination in Employment Act) requires that employees 40 and older receive at least 21 days to consider the agreement and 7 days to revoke after signing — protecting older workers from rushed decisions.

Read the release carefully before signing. It may include non-disparagement clauses (you can't publicly criticize the company), non-compete provisions (which limit where you can work afterward), non-solicitation provisions (you can't recruit former colleagues or solicit former clients), and confidentiality requirements. Non-competes in particular vary enormously in enforceability by state — California generally doesn't enforce them, while Florida and many other states do. Understanding what you're agreeing to before signing is more valuable than rushing to receive the payment.

How Severance Is Calculated

There's no federal law requiring severance pay in the United States — it's entirely at employer discretion except where contractually promised. The most common formula: one to two weeks of pay per year of service, often with a cap at 26 weeks. One week per year is the industry minimum; more generous employers offer two weeks per year. Executive-level positions commonly receive one to three months per year of service.

For a 7-year employee earning $78,000 per year at one week per year: 7 weeks × ($78,000 ÷ 52 weeks) = 7 × $1,500 = $10,500 gross. At two weeks per year: $21,000 gross. Some companies add a lump sum for benefits continuation or specific roles (particularly sales, where commission on deals in progress may be owed). Others calculate based on regular pay only, excluding bonuses and commissions from the calculation even though those were part of regular compensation — creating a point of potential negotiation.

Tax Treatment of Severance Pay

Severance is ordinary income — taxed at your marginal federal and state rates, subject to Social Security (up to the wage base, if not already exceeded) and Medicare taxes. Your employer withholds taxes from severance at either the supplemental wage withholding rate (22% for amounts up to $1 million in 2024) or at your regular withholding rate. The supplemental rate often causes underwithholding for people in higher brackets: if your marginal rate is 32%, withholding at 22% means you'll owe the additional 10% when you file your taxes.

Kate, 42, in Boston, Massachusetts received $38,000 in severance after 9 years at her company. Her employer withheld 22% federal ($8,360) plus 5% Massachusetts state tax ($1,900) = $10,260 total withholding. Her marginal federal rate is 24% and Massachusetts taxes at 5%. Actual federal tax on $38,000: 24% = $9,120. She owes $760 more than withheld in federal tax — she should either adjust estimated tax payments or be prepared for a tax bill when she files. For people in the 32% or 35% brackets receiving large severance packages, the underwitholding gap can be $5,000 to $15,000.

What Affects Severance Amount: Negotiable Factors

Even at companies with standard formulas, there are often negotiable elements around termination that affect total departing compensation. COBRA continuation: COBRA (continuation of employer health benefits) typically costs $600 to $2,200 per month for self-only coverage and $1,500 to $4,500 for family coverage — dramatically more than the employee-share contribution. Negotiating 2 to 6 months of COBRA premium coverage as part of the departure package is common and can add significant value.

Unvested stock or equity: depending on company policy and departure circumstances, negotiating accelerated vesting of unvested stock options or RSUs is sometimes possible, particularly for senior employees or in situations where the employer is downsizing (suggesting the termination is company-driven rather than performance-based). At a startup where your unvested options represent significant value, this negotiation can dwarf the cash severance in total value.

Commission on deals in progress: sales professionals terminated mid-quarter often have deals that will close after their departure. Many severance agreements attempt to exclude commission on these deals. Negotiating commission owed on sales you originated or materially advanced, even if they close after termination, is legitimate and often worth fighting for specifically.

When to Consider an Employment Attorney

If your termination involved potential discrimination, retaliation for protected activity (reporting illegal conduct, filing workers' compensation claims, taking FMLA leave), or violation of an employment contract, your legal claim may be worth more than the offered severance — meaning signing the release could cost you significant money. An initial consultation with an employment attorney typically costs $150 to $350 and can clarify whether your situation has merit that changes the negotiation calculus. Many employment attorneys work on contingency for discrimination and wrongful termination cases.

Even without a specific legal claim, an employment attorney can review your severance agreement for provisions that are unusually restrictive, illegal in your state, or negotiable — particularly non-compete language, commission treatment, and equity provisions. For executives and senior professionals receiving severance packages exceeding $50,000, professional review of the agreement costs far less than the value it can protect.
