Severance Pay Calculator
Estimate severance from the terms of your employer’s policy or offer, or from the federal formula if you are a federal employee. Optional checks cover WARN Act back pay after a short-notice mass layoff and the review periods for workers 40 and older. Free, and calculated in your browser.
Federal law does not require private employers to pay severance, so the formula comes from your employer. Enter the terms from the policy, handbook, contract or offer letter.
Estimate
- Weekly pay used: $1,153.85
- Service counted: 5 years
- 10 weeks of pay at $1,153.85 a week
WARN Act notice check (optional)
The federal WARN Act requires 60 days’ written notice before certain plant closings and mass layoffs. If notice was short, a court can award back pay and benefits for each day of the shortfall. This part applies only if both statements below are true.
The WARN estimate appears only when both statements are checked. Exceptions (for example a faltering company, unforeseeable business circumstances, a natural disaster, or a temporary project) can also change the result.

Is Severance Pay Required?
Usually not. The U.S. Department of Labor states that there is no requirement in the Fair Labor Standards Act for severance pay, and that severance is a matter of agreement between an employer and an employee. When a private employer pays it, the amount comes from its own policy, a contract, a union agreement, or an offer made at separation.
That is why the main calculator asks for your employer’s terms instead of applying a legal rate. A common structure is a number of weeks of pay per year of service, sometimes with a minimum or a cap. Read the policy for how it counts a partial year, since that can change the result by a week or more.
Federal civilian employees are different: 5 U.S.C. 5595 sets a formula. OPM’s fact sheet describes it as one week of basic pay per full year of service through 10 years, two weeks per full year after that, 25% of the applicable amount for each full 3 months beyond the last full year, plus an age adjustment of 2.5% of that basic allowance for each full 3 months of age over 40. The lifetime total cannot exceed 52 weeks. OPM’s own example ($1,500 a week, 20 years 4 months of service, age 45 years 8 months) produces $70,912.50, and the calculator reproduces it.
Not every separated federal employee is covered. The statute excludes, among others, an employee who at separation has fulfilled the requirements for an immediate annuity or is entitled to other severance pay from the Government, and OPM’s fact sheet adds an employee who declines a reasonable offer of another position. The calculator gives no figure if you tick the immediate-annuity box.
WARN Act Back Pay
The Worker Adjustment and Retraining Notification Act requires an employer to give 60 days’ written notice before a covered plant closing or mass layoff. It covers an employer with 100 or more employees not counting part-time workers, or 100 or more employees who together work at least 4,000 hours a week, not counting overtime. A plant closing means 50 or more employees losing their jobs at one site within 30 days; a mass layoff means at least 500 employees at a site, or 50 to 499 who are at least 33% of the site’s workforce.
When notice is short, 29 U.S.C. 2104 makes the employer liable for back pay for each day of violation, at the higher of the employee’s average regular rate over the last 3 years or final regular rate, plus benefits. The period is capped at 60 days and never more than half the days the employee was employed by the employer. The amount is reduced by wages paid for the period and by voluntary, unconditional payments the employer was not legally required to make.
Courts disagree on how to count the days, but most federal appeals courts that have decided the question count only work days within the violation period: the Fifth Circuit (Carpenters District Council v. Dillard Dept. Stores, 15 F.3d 1275), followed by the Sixth, Tenth and Eighth Circuits (Breedlove v. Earthgrains Baking Cos., 140 F.3d 797, which describes working days as the majority rule). The Third Circuit counts every calendar day (United Steelworkers v. North Star Steel Co., 5 F.3d 39). The calculator shows the work-day figure first and the calendar-day figure second. The Department of Labor notes that it has no enforcement role in seeking these damages; workers or their representatives enforce it by suing under 29 U.S.C. 2104, and some states have their own plant-closing laws.
Signing a Release at 40 or Older
Severance offers often come with a release of claims. For a release of federal age discrimination claims to be valid for a worker 40 or older (the ADEA’s age threshold), the Older Workers Benefit Protection Act in 29 U.S.C. 626(f) requires, among other things, at least 21 days to consider the agreement (45 days when the offer is part of a group exit program), written advice to consult a lawyer, and 7 days after signing to revoke it.
Under 29 CFR 1625.22, material changes to the final offer restart the 21 or 45 days, and an employee may sign sooner if the choice is knowing and voluntary. The EEOC adds that no agreement can stop you from filing a charge or taking part in an EEOC investigation.
Worked Example
A $60,000 salary is about $1,153.85 a week. Under a policy of 2 weeks per year of service, 5 years 6 months pro-rated is 11 weeks, or $12,692.31 before taxes. If the policy counts full years only, it is 10 weeks ($11,538.46); if a partial year counts as a full one, 12 weeks ($13,846.15). The weekly figure divides the annual pay by 52.
What This Calculator Does Not Do
- Decide what an employer must pay. For private employers the policy or agreement controls; the tool only applies the terms you enter.
- State severance or plant-closing laws. Some states have their own notice laws; they are not modelled here.
- WARN coverage and exceptions. Whether WARN applies depends on headcounts, the 90-day aggregation rule and exceptions such as a faltering company, unforeseeable business circumstances or a natural disaster. The WARN figure also leaves out benefits.
- Taxes, unemployment benefits and continued health coverage. Results are before tax and do not address how severance affects other benefits.
- Official federal computations. Creditable service and the weekly rate for variable schedules are set by your agency under 5 CFR 550.707.
Frequently Asked Questions
Does federal law require severance pay?
Not for private employers. The Department of Labor says there is no requirement in the Fair Labor Standards Act for severance pay and that it is a matter of agreement between employer and employee. Federal civilian employees have a statutory formula under 5 U.S.C. 5595.
How is severance usually calculated?
Private employers set their own formula, often a number of weeks of pay per year of service, sometimes with a minimum and a maximum. Enter those terms to see the result. The policy or offer letter is what counts.
What does the WARN Act pay if I did not get 60 days’ notice?
If WARN covers the employer and the layoff, the employer is liable for back pay and benefits for each day of the violation, up to 60 days and never more than half the days you were employed, reduced by wages and certain payments made for that period. Most federal appeals courts count only work days in that period; the Third Circuit counts calendar days. The calculator shows both, work days first.
How long do I have to consider a severance agreement if I am over 40?
For a valid waiver of federal age discrimination claims, at least 21 days, or 45 days if the offer is part of a group exit or layoff program, and then 7 days after signing to revoke. The agreement does not take effect until the revocation period ends.
How much severance do federal employees get?
Under the OPM formula, one week of basic pay per full year of service through 10 years, two weeks per year after that, a partial-year credit, and an age adjustment for employees over 40, capped at 52 weeks over a lifetime. Choose the federal option in the calculator.
