Severance Runway Calculator

July 1, 2026 • By the Investor Sam Editorial Team • Reviewed by Berly Sam Varghese, Editor
Severance is not just a lump sum — it is time. This calculator converts your package into a real job-search runway by netting out COBRA health insurance, factoring in unemployment insurance, and drawing down your emergency fund. Knowing your true runway in months changes how you search — and what you are willing to accept.

Example: Severance received (after tax): 30000 $ · Monthly living expenses: 5000 $ · Emergency fund available: 20000 $ · Monthly unemployment insurance benefit: 1800 $ · Monthly COBRA premium: 700 $

Total runway (months)12.82
Comfortable search window (70% of runway)8.97
Total resources available$50,000
Net monthly burn rate$3,900

Worked example

A $30,000 after-tax severance plus $20,000 emergency fund = $50,000 total. Monthly expenses of $5,000 plus $700 COBRA minus $1,800 unemployment = $3,900 net monthly burn. Runway: 50,000 / 3,900 = 12.8 months. Comfortable search window: 9 months. That is enough time to be selective — not desperate — which typically leads to higher offers.

Frequently asked questions

Is severance pay taxable?

Yes — severance is ordinary income, subject to federal income tax, state income tax, and payroll taxes (FICA). Employers typically withhold at the supplemental wage rate of 22% for federal, but your true marginal rate at filing varies. Use the Windfall Tax Calculator to estimate your specific bill.

How does COBRA work after a layoff?

COBRA lets you continue your employer health plan for up to 18 months after termination. You pay the full premium — both the employee and employer share — plus a 2% administrative fee. Average family COBRA costs roughly $1,700–2,200 per month; compare with ACA marketplace plans in your area, which may be subsidized based on your reduced income.

Should I negotiate severance before signing?

In most cases, yes. Severance packages are negotiable, particularly for employees with long tenure or performance documentation. One to two weeks per year of service is a common baseline, but companies often go higher for senior roles or when legal risk is present. You typically have 21–45 days to consider and 7 days to revoke a signed agreement.

Does unemployment insurance reduce my severance?

Rules vary by state. Some states disqualify you from unemployment benefits while you are receiving severance; others allow concurrent collection. Check your state's unemployment website immediately after separation, as filing early preserves your eligibility date.
