WARN Act Tools & Calculators
Practical, no-sign-up calculators built around the federal WARN Act and what it means for workers, eligibility, the value of the notice period, and layoff risk by sector.
According to the U.S. Department of Labor, the federal WARN Act has required 60 days’ advance notice of mass layoffs since 1988. PlainLayoffs has compiled 8,798 WARN notices covering 1,411,142 workers; these tools turn those public rules into quick, no-sign-up answers. See our methodology for sourcing.
WARN Eligibility Checker
Does a planned layoff trigger the federal WARN Act 60-day notice? Test it from employer size, workers affected, and share of the site workforce.
Open tool →WARN Notice & Severance Estimator
Value the 60-day WARN notice period in pay, plus a typical severance range for your tenure, to sanity-check an offer after a layoff.
Open tool →Layoff Impact Risk Checker
See how WARN Act layoff activity in your industry and company-size band compares to the national pattern.
Open tool →Why it matters
These calculators run on the same public WARN-Act record this site tracks, every threshold and notice-period rule below is drawn from real filings, not estimates.

About these tools
Each tool runs entirely in your browser, nothing you enter is sent anywhere or stored. They are educational aids built on the public rules of the federal WARN Act and observed WARN filing patterns, and they are not legal or financial advice. For the law itself and what it means in practice, see our WARN Act guide and methodology.
Where to start
Three quick checks if you've received, or expect, a WARN notice.
- Confirm whether your situation is even covered by the WARN Act's 100-employee / 50-worker thresholds. WARN eligibility checker
- Estimate the notice pay you may be owed if the required 60-day warning was skipped. WARN pay estimator
- Gauge the wider impact of a layoff round and your next financial steps. Layoff impact checker
These tools apply the federal WARN Act rules; many states have stricter mini-WARN laws with lower thresholds, so confirm your state's rules too.
