Estimate a severance package, what it nets after tax, and how long it will actually last you.
Your details
Severance is almost never legally required in the US — the formula is whatever your employer's policy or your contract says.
Adjustments

Runway
Varies by state, and severance can delay eligibility in some of them. Enter zero if unsure.
Once employer coverage ends you pay the full premium plus a 2% administration fee.

What this means
- The gross figure of $26,308 is not what arrives. Severance is treated as supplemental wages and withheld aggressively — commonly a flat 22% federal rate on top of payroll and state tax — leaving roughly $17,889.
- Adding your $18,000 in savings gives about 7.4 months at $4,850 a month including COBRA. Health coverage is the cost people forget: the employer's share disappears, so the premium often triples.
- Severance is rarely required by law in the United States, which means the initial offer is usually a starting position rather than a fixed policy. Signing typically waives your right to sue, and that release has value — it is what gives you something to negotiate with.
How the severance pay calculation works
Severance in the United States is almost never a legal entitlement. Outside of a written contract, a collective agreement, or a mass layoff triggering WARN Act notice requirements, an employer generally owes nothing beyond wages already earned. What you are offered comes from company policy, from a desire to protect reputation, and above all from wanting a signed release of claims. That last point is the important one, because it means the first offer is a negotiating position rather than a fixed calculation.
The most common formulas are one or two weeks per year of service, often with a floor for short-tenured employees and a cap for long-serving ones. Senior roles frequently do better, and packages sometimes include a prorated bonus, accelerated equity vesting, extended health coverage, or outplacement services. These non-cash items are often easier for an employer to concede than additional weeks of pay, which makes them worth asking for specifically.
The number that matters is not the gross. Severance is taxed as supplemental wages, which in practice means aggressive withholding — commonly a flat twenty-two percent federal rate on top of Social Security, Medicare and state tax. A package presented as six months of salary lands as considerably less, and planning around the gross figure is how people run short.
Health insurance is the expense that most often surprises people. Employer-sponsored coverage typically has the employer paying seventy percent or more of the premium, and that contribution stops. COBRA lets you keep the same plan but at the full cost plus a two percent administrative fee, which frequently means a premium three or four times what was coming out of your paycheck. Marketplace plans are worth pricing against it, since a drop in income may qualify you for substantial subsidies.
Frequently asked questions
Am I entitled to severance pay?
In the US, usually not. Absent an employment contract, a union agreement or a WARN Act situation, severance is discretionary. It is offered mainly to obtain a signed release of legal claims, which is precisely why there is normally room to negotiate.
How much severance is typical?
One to two weeks per year of service is the common range, often with a minimum of a few weeks and a cap at the top end. Executive packages are frequently far more generous and negotiated individually rather than set by policy.
Why is so much tax taken out of severance?
It is classified as supplemental wages, which are typically withheld at a flat twenty-two percent federal rate up to a million dollars, plus Social Security, Medicare and state tax. This is withholding rather than final liability — if it overshoots your actual rate, the difference comes back at filing.
Can I collect unemployment while receiving severance?
It depends on your state and on how the severance is paid. Some states treat a lump sum as wages that delay eligibility, others do not; salary continuation is more likely to postpone benefits than a single payment. File promptly regardless and let the agency determine it.
Should I negotiate my severance?
Usually yes, politely and in writing. You are being asked to sign away legal claims, which has value to the employer. Beyond weeks of pay, ask about extended health coverage, accelerated vesting, keeping equipment, outplacement help and the wording of any reference — these often cost the company less and are conceded more readily.
