How We Calculate: Methodology & Data Sources

Our formulas are not guesswork. Each calculator follows published government rules:

Federal overtime: Based on the Fair Labor Standards Act (FLSA): non-exempt employees earn at least 1.5× their regular rate after 40 hours in a workweek, as published by the U.S. Department of Labor.
California overtime: Follows California Labor Code Section 510: 1.5× pay after 8 hours in a day, 2× after 12 hours, plus the seventh-consecutive-day rules from the California Department of Industrial Relations.
Overtime tax deduction: Our "no tax on overtime" estimates follow IRS guidance on the federal deduction for qualified overtime compensation (tax years 2025–2028).

Every formula is checked against official examples and covered by automated tests before release. When the rules change, we update the affected calculator and its guide.

Primary sources we rely on

Results are estimates for information only — not legal, tax, or payroll advice.
