Payroll & HR

Payroll and HR calculations are one of the niches where getting the answer wrong has legal consequences. FLSA overtime violations carry back-wages plus liquidated damages. Miscalculated withholding puts the employer on the hook for the shortage. Late WARN Act notices trigger statutory penalties. The tools in this category aim to make the underlying rules legible and the math honest, without pretending that a web calculator is a substitute for an employment lawyer or a CPA when the answer actually matters.

Every tool in this cluster is built on a named regulatory source. Overtime pay follows the Fair Labor Standards Act (FLSA) at 29 CFR Part 778, with state-specific overrides where they differ (California's daily overtime rules, for example). Withholding estimators use the IRS Publication 15-T percentage method and reference the current tax year's published brackets. PTO accrual follows standard payroll practice rather than a single binding rule, since PTO is largely contractual. WARN Act checks follow the plain text of 29 USC 2101-2109.

These tools are for small-business operators, HR generalists, and workers who want to sanity-check a paycheck or a notice. They are not for anything that goes on a government filing or a lawsuit exhibit. For those, use professional payroll software or consult counsel. Where a regulation has recently changed (tax brackets for a new year, state minimum wage indexing, WARN threshold adjustments), the tool's "last reviewed" date tells you when it was last verified against the current rules.

Every calculation happens in your browser. Wages, tax amounts, and employee counts you enter never leave your device and are not stored. No signup, no email gate, no follow-up marketing. The privacy policy has the full detail on what data the site handles.

The cluster is built out one tool at a time, with editorial review between each. If a calculator you need is missing, see the contact page and describe the scenario and the regulatory source you would follow. Tools grounded in a named federal or state statute get prioritized over generic "what if" scenarios.
