Severance pay is calculated using your salary, length of employment, and sometimes your age or position — but the formula varies by employer and state

There is no federal law that requires severance or sets a standard formula. What you receive depends on what your employer's severance policy says, what your employment contract states, and sometimes what state law requires in your industry. Most employers use one of three methods: a flat amount, a multiple of your weekly or monthly pay, or a formula based on years of service.

The most common approach is weeks or months of pay per year of service. For example, an employer might offer one week of pay for each year you worked there. Someone who worked five years at $1,000 per week would receive $5,000. Another employer might offer two weeks per year, which would double that amount. A few employers use a flat amount — say, $5,000 regardless of tenure — but this is less common for full-time staff.

Your actual severance check will be reduced by taxes, and sometimes by deductions for health insurance continuation (COBRA), unpaid loans, or other items your employer is legally permitted to withhold. The gross amount your employer calculates is what matters for understanding the formula; the net amount is what lands in your account.

Key Takeaways

  • Most severance formulas multiply your weekly or monthly salary by the number of years you worked, though some employers use a flat amount instead.
  • Your employer's written severance policy or employment contract is the document that controls what you receive — not state law or industry standard.
  • Severance is reduced by federal and state income tax, and sometimes by COBRA premiums or other lawful deductions before you receive it.
  • Some states require severance only in specific situations, such as mass layoffs or plant closures, while others do not require it at all.
  • Your job title, salary grade, and reason for separation can all affect whether you receive severance and how much it is.

The three main severance formulas employers use

Weeks or months per year of service is the most transparent formula. Your employer states the rate — for example, "one week of pay per year of employment" — and multiplies it by your tenure. If you earned $2,000 per week and worked there for eight years, you would receive $16,000 gross. This method rewards longer tenure and is straightforward to calculate.

A multiple of your final salary works similarly but uses a lump percentage instead of a per-year rate. An employer might offer "three months of salary" or "50% of your annual salary." If you earned $60,000 per year, a three-month severance would be $15,000 gross. This method is simpler for employers to administer but does not differentiate between someone who worked two years and someone who worked twenty.

A flat amount is less common but does occur, especially in smaller companies or for certain roles. The employer offers the same severance to all departing employees in a category — for instance, $3,000 for any full-time employee. This method is the least generous to long-tenured staff but the easiest to budget.

Some employers combine methods. They might offer one week per year of service, with a minimum of four weeks and a maximum of twelve weeks. This protects newer employees from receiving almost nothing while capping the liability for very long-tenured staff.

How your salary, position, and tenure affect the amount

Your base salary is the foundation of most severance calculations. Severance is almost always calculated on your regular hourly wage or annual salary, not on bonuses, commissions, or stock options. If you earned $50,000 per year as a base salary plus $10,000 in annual bonuses, most employers will calculate severance on the $50,000 only. Check your severance letter to confirm what your employer included.

Your length of employment directly increases severance under per-year formulas. An employee with ten years of service receives twice the severance of one with five years, assuming the same salary and formula. Some employers cap tenure at a certain number of years — for example, "maximum of 20 years of service credited" — which means a 30-year employee receives the same severance as a 20-year employee.

Your job title or pay grade can create different severance formulas for different roles. Executives sometimes receive more generous packages than individual contributors. A company might offer managers "two months per year of service" while offering staff "one month per year of service." This is legal and common in larger organizations.

Your reason for separation matters in some severance policies. Layoffs and plant closures often trigger severance, while resignation or termination for cause may not. Some employers offer reduced severance for voluntary departures. Read your severance letter to see whether it notes a reason, because that reason may explain why your amount differs from what a coworker received.

What happens to severance after taxes and deductions

Severance is taxable income. Your employer will withhold federal income tax, Social Security tax (6.2% up to the annual wage cap), and Medicare tax (1.45%) from your severance check. Your state may also withhold state income tax. The amount withheld depends on your tax bracket and your W-4 form on file with your employer.

If you are covered by a group health insurance plan through your employer, you may be offered COBRA continuation coverage. If you elect COBRA, your employer may deduct the premium from your severance or final paycheck. COBRA premiums are often substantial — sometimes $500 to $1,500 per month for family coverage — so confirm whether your severance is being reduced by this cost.

Your employer may also deduct outstanding loans (such as a 401(k) loan), unpaid advances, or overpaid wages from your severance. These deductions are legal if your state permits them and if your employment agreement or severance policy disclosed them. Ask your employer or HR department for an itemized breakdown of any deductions before you receive your check.

The gross severance amount — before taxes and deductions — is what you should use to understand your severance formula. The net amount is what you actually receive. If your severance letter shows $20,000 gross but you receive $14,500 after taxes and COBRA, the formula was based on the $20,000.

State laws that require or limit severance

Most states do not require severance at all. Employers in these states can offer no severance, and it is not illegal. However, a few states have specific rules for certain situations.

California does not require severance for ordinary layoffs, but it does require employers to pay accrued, unused vacation time when an employee is terminated. This is sometimes confused with severance but is a separate obligation.

New York requires severance only for mass layoffs affecting 500 or more employees at a single location, or 1,000 or more employees statewide. The amount is one week of pay per year of service, up to a maximum of 26 weeks.

Illinois requires severance for mass layoffs of 75 or more employees at a single location. The amount is one week of pay per year of service, with a minimum of two weeks.

Connecticut requires severance for plant closures affecting 75 or more employees. The amount is one week of pay per year of service, with a minimum of two weeks.

If your employer is offering severance, it is almost always because of a company policy or your employment contract, not because of state law. Check your employee handbook or severance agreement to see what your employer's policy states. If your state has a mass layoff law and you are affected, your employer must meet that minimum even if their policy offers less.

How to verify your severance calculation is correct

Request a written breakdown from your employer or HR department. Ask them to show you the formula they used, your salary amount, your tenure, and any adjustments or caps they applied. A correct breakdown will look like this: "Base salary: $60,000 per year. Tenure: 5 years. Formula: 1 week per year of service. Calculation: ($60,000 ÷ 52 weeks) × 5 = $5,769.23 gross."

Check your employment contract and employee handbook for the severance policy. If your severance letter does not match the policy you have on file, ask HR to explain the difference. Sometimes policies change, or exceptions are made, but you are may have access to to an explanation.

Verify your tenure dates. Confirm the start date and end date your employer used. Some employers count only full years of service, while others count partial years. If you worked from January 2015 to June 2024, that is 9.5 years. Some employers would credit you with 9 years, others with 10. Ask which method they used.

If you believe your severance is incorrect, contact your state's labor department or a local employment attorney. Many attorneys offer free initial consultations and can review your severance letter and policy in minutes. Severance disputes are common enough that many attorneys handle them routinely.

Frequently Asked Questions

Does severance include unused vacation or sick time?

Not usually. Severance and accrued paid time off are separate. Your employer must pay out accrued vacation in most states, but that is not severance — it is compensation for time you earned. Severance is a separate payment based on your tenure and salary. Your severance letter should itemize both amounts if you are receiving both.

Can my employer reduce my severance if I sign a non-compete agreement?

Yes. Some employers offer severance only if you sign a non-compete, non-solicitation, or confidentiality agreement. If you refuse to sign, they may reduce or eliminate severance. This is legal in most states, though a few states limit the enforceability of non-competes. Review any agreement before signing and ask HR what happens if you decline.

Is severance different from a severance package?

A severance package usually includes severance pay plus other benefits, such as extended health insurance, outplacement services, or a reference letter. The severance pay is the cash portion. When you see "severance package," ask HR to itemize what is included so you understand what is cash and what is a service.

What if I was fired for cause — do I still get severance?

It depends on your employer's policy. Some policies exclude severance for termination for cause, while others do not. Your severance letter will state whether cause affects your amount. If you believe you were wrongfully terminated, consult an employment attorney, as that is a separate legal question from severance calculation.

Can severance be paid in installments instead of a lump sum?

Yes, if your employer offers it. Some employers pay severance over several months or as part of your regular paycheck schedule. Ask your HR department whether you can request installment payments and whether that affects the total amount you receive. Some employers reduce the total if you request installments, while others do not.
