Severance & Benefits Cost Estimator: How HR Can Accurately Budget for Layoffs

IIf you’ve ever been tasked with planning a workforce reduction, you know how complicated the math can get. It’s not just severance pay—you need to account for PTO payouts, employer taxes, benefits continuation, outplacement, and administrative costs. Miss a piece, and your budget projections could be off by tens (or hundreds) of thousands of dollars.

That’s where a Severance & Benefits Cost Estimator comes in. Instead of wrestling with manual spreadsheets, you upload employee data, set your severance policy (e.g., weeks per year, caps), and choose whether to include PTO, COBRA, employer taxes, or outplacement.

The tool instantly calculates a bold top-line total, shows a chart breaking down each component, and provides a per-employee table you can export to PDF or CSV.

Let’s look at how severance works, what’s included in total separation costs, and how HR teams can use an estimator to budget with confidence.

What Is Severance Pay?

Severance pay is compensation offered to employees when their employment ends due to circumstances such as layoffs, position eliminations, or workforce reductions.

While not required under U.S. federal law, many employers provide severance as both a goodwill gesture and a risk-management strategy. Offering severance can reduce the likelihood of lawsuits, negative publicity, or damage to employer branding.

It also helps maintain morale among remaining employees, who see that their colleagues were treated fairly.

Common severance structures include:

  • Tenure-based formula: One to two weeks of pay per year of service, often with minimum and maximum limits.

  • Flat packages: A set number of weeks (e.g., four or six) regardless of how long the employee worked.

  • Executive-level packages: More generous, sometimes several months of pay, bonus treatment, equity handling, and extended benefits.

Key takeaway: Severance pay is a bridge that supports employees during transition while protecting employers. But cash payments are just one piece of the overall cost puzzle.

What’s Included in a Severance Package?

When people talk about a “severance package,” they usually mean the full suite of benefits offered during offboarding—not just a paycheck. A well-rounded package signals professionalism, compassion, and legal foresight.

Typical components include:

  • Severance pay: Lump sum or salary continuation for a defined period.

  • PTO payout: Accrued vacation or sick leave, depending on state law and company policy.

  • COBRA/benefits continuation: Employer subsidies for health insurance premiums to soften the immediate impact of losing coverage.

  • Outplacement services: Career coaching, resume writing, and job search support. Providers like TurboTransitions combine AI-powered coaching (via PruE AI) with human support to accelerate reemployment.

  • Legal/admin costs: Payroll processing, drafting/reviewing agreements, and HR staff time.

Key takeaway: A severance package should be viewed holistically. The “true cost” often goes beyond severance pay to include benefits, compliance steps, and hidden administrative expenses.

Why You Need a Severance & Benefits Cost Estimator

Budgeting for a reduction in force (RIF) is rarely simple. Finance needs precise cost projections, HR needs visibility into employee-level impact, and Legal needs assurance that policies are applied consistently. A severance cost estimator brings these pieces together.

Key advantages:

  • Automates calculations: Apply company policies across an entire workforce instantly.

  • Visualizes impact: Breaks costs into buckets (severance vs. PTO vs. COBRA vs. taxes).

  • Models scenarios: Compare “what if” options (e.g., 1 week vs. 2 weeks per year, with/without COBRA subsidy).

  • Employee-level detail: Ensures accuracy for contracts and compliance.

  • Exportable results: Create PDF reports for leadership presentations or CSVs for Finance tracking.

Key takeaway: Instead of guesswork, a calculator provides a data-backed plan that HR and Finance can confidently present to leadership.

How to Calculate Severance Pay

For HR teams without a dedicated tool, calculating severance requires a manual, step-by-step approach:

  1. Determine base pay: Annual salary ÷ 52 weeks or hourly rate × weekly hours.

  2. Apply policy formula: Example—two weeks of pay per year of service, with caps if applicable.

  3. Add PTO payout: Based on state law and internal policy.

  4. Include payroll taxes: Federal, state, Social Security, and Medicare apply to severance just as they do to wages.

  5. Account for benefits costs: COBRA premiums × duration of coverage the company agrees to subsidize.

  6. Factor in outplacement services: Per-employee cost if included.

  7. Add administrative/legal costs: Often overlooked but still a real expense.

Key takeaway: While this can be done manually, calculations quickly become complicated at scale. An estimator reduces errors and saves hours of work.

Are Severance Payments Taxable?

Yes. Severance pay is treated as taxable income by the IRS and most states.

  • Federal withholding: Lump-sum severance is typically taxed as “supplemental wages,” subject to a flat 22% withholding. Larger amounts (over $1M) may be taxed at 37%.

  • Payroll taxes: Employers must still withhold and pay their share of Social Security and Medicare.

  • State taxes: Many states impose additional withholding requirements.

Employees may also face different net amounts depending on whether they receive a lump sum or salary continuation.

Key takeaway: Payroll taxes and withholding significantly increase the employer’s total cost. Always factor them in to avoid under-budgeting.

Severance vs. Unemployment Benefits

One of the most common employee questions is how severance impacts eligibility for unemployment insurance.

  • Some states delay benefits: Employees cannot collect unemployment until the severance pay period ends (e.g., if severance is paid as salary continuation).

  • Other states allow overlap: Employees can receive unemployment even while collecting severance, especially if it is paid as a lump sum.

  • Employer communication matters: Confusion about eligibility can frustrate employees. Including an FAQ in the separation packet helps manage expectations.

Key takeaway: Severance doesn’t automatically disqualify employees from unemployment, but the rules vary by state. HR should provide general guidance and direct employees to their state unemployment agency.

COBRA and Benefits Costs After Layoffs

COBRA continuation is often one of the most expensive and overlooked parts of a layoff. Under federal law, employees may continue group health coverage for up to 18 months, but at their own expense. Employers sometimes subsidize part of this cost to ease the transition.

  • Average employer cost: According to the Kaiser Family Foundation, family coverage averages $23,968 annually ($1,997/month).

  • Cost example: If an employer covers two months of premiums for 50 employees, that’s nearly $200,000 in COBRA costs.

  • Additional benefits: Life insurance, disability, and retirement contributions may also carry continuation costs depending on policy.

Key takeaway: Benefits continuation can rival or even exceed severance pay. Include it in every cost projection to avoid surprises.

Using a Severance & Benefits Cost Estimator

Here’s how HR teams typically leverage these tools during planning:

  1. Upload employee data: Salary/hourly rate, tenure, PTO balance, benefits status.

  2. Set company policy: Define severance formulas, caps, and executive exceptions.

  3. Add optional costs: PTO payout, COBRA subsidy, employer taxes, outplacement.

  4. Generate report: Produces both a high-level cost summary and detailed breakdowns.

  5. Export and share: PDFs for leadership presentations; CSVs for Finance tracking.

Key takeaway: A structured estimator ensures HR, Finance, and Legal work from the same assumptions. It turns a stressful, error-prone process into a clear plan backed by data.

How to Budget for a Reduction in Force (RIF)

RIF costs go beyond severance packages. To budget correctly, consider:

  • Direct costs: Severance, PTO, COBRA, outplacement.

  • Indirect costs: Legal, compliance, admin time.

  • Opportunity costs: Morale and retention impact on survivors.

Using a cost estimator helps quantify direct costs accurately, so leadership can focus on managing indirect and cultural impacts.

Key takeaway: You can’t manage what you don’t measure. Start with accurate direct cost estimates.

FAQ: Severance & Benefits Cost Estimation

How do I calculate severance pay?

Start with the employee’s base salary or hourly rate and apply your company’s severance policy formula (e.g., two weeks per year of service).

Then add other required or optional costs: payout of accrued PTO or vacation, employer payroll taxes (Social Security and Medicare), COBRA or other benefit subsidies, and any outplacement or administrative costs. This ensures you capture the “true cost” rather than just the paycheck portion.

What’s included in a severance package?

A complete package often goes beyond cash. Standard components include severance pay, PTO payout, continuation of health insurance or other benefits, and sometimes outplacement support like coaching or resume services. Employers should also account for less obvious costs such as legal review of agreements, payroll processing, and HR administration time.

Are severance payments taxable?

Yes. Severance is considered supplemental wages under IRS rules. Federal income tax withholding usually applies at a flat rate (currently 22% for lump sums), and Social Security and Medicare taxes must also be withheld.

Employers must pay their share of payroll taxes on severance as well, which can add significantly to the total cost. State income tax withholding may apply too, depending on jurisdiction.

Do severance and unemployment benefits affect each other?

It depends on the state. In some states, severance is treated as continued wages, and employees may need to wait until the severance period ends before unemployment benefits start.

In other states, employees can collect unemployment while also receiving severance, especially if the payment is structured as a lump sum. Employers should be prepared for employee questions and provide state-specific guidance when possible.

How much does COBRA cost after a layoff?

COBRA continuation coverage allows employees to remain on their health plan for up to 18 months, but at full cost. The average monthly premium for family coverage is about $1,997 according to Kaiser Family Foundation data. If an employer agrees to subsidize one, two, or three months of premiums for multiple employees, costs can add up quickly and should be included in layoff budgets.

What’s typical severance by years of service?

Most employers use tenure-based formulas like one to two weeks of base pay per year of service. Some apply caps—commonly 12 to 26 weeks—to limit liability. Executives and senior leaders often receive more generous packages that may include several months of salary, bonus eligibility, or equity treatment, especially when contracts or retention agreements are in place.

What’s the difference between severance and notice pay?

Severance is compensation provided after employment ends, usually as a goodwill gesture or legal protection. Notice pay, by contrast, is wages provided in place of advance notice if the employer cannot give the required lead time (for example, under WARN or a state mini-WARN law).

While both involve payments during separation, notice pay is a legal compliance issue, whereas severance is usually discretionary.

How do I budget for RIF costs?

Use a severance and benefits estimator or spreadsheet to calculate the direct financial costs across all affected employees: severance pay, PTO, COBRA, payroll taxes, and outplacement. Then factor in legal review, HR time, and cultural considerations such as the potential impact on morale and employer brand. Presenting both the hard numbers and the “soft costs” gives leadership a realistic picture of the full impact of a reduction in force.


Wrapping Up

Layoffs are never easy, but budgeting for them doesn’t have to be guesswork. A Severance & Benefits Cost Estimator gives HR and Finance teams a clear view of the total cash impact—severance, PTO, taxes, COBRA, outplacement, and admin.

By turning complex spreadsheets into a simple dashboard with totals, charts, and per-employee tables, you save time and reduce errors. Even more importantly, you walk into executive meetings with confidence that your numbers are solid.

And when paired with career transition support like TurboTransitions, employees leave with more than a paycheck—they leave with tools, coaching, and confidence for what’s next.

Key takeaway: Accurate cost estimation is the foundation of responsible workforce planning. A reliable estimator helps HR lead with clarity and credibility.
