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 more than 4,800 WARN notices covering more than 930,000 workers as of March 2026; these tools turn those public rules into quick, no-sign-up answers. See our methodology for sourcing.

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.
