About HRCalcs
HRCalcs is a free suite of HR compliance calculators for US employers, payroll specialists, and HR teams. Every tool is built from official US Department of Labor, Internal Revenue Service, and Code of Federal Regulations sources — cited on every result page so you can verify the numbers yourself.
Source-first
Every formula traces back to a specific CFR section or DOL Fact Sheet. Nothing is an opinion — numbers come from rules.
Private by design
Calculators run in your browser. Inputs (salary, hours, bonuses) never leave your device. No account, no tracking of what you compute.
Built for the work
Results are shaped around the question HR is actually trying to answer — not a textbook table of every possible number.
How we build a calculator
- Identify the underlying federal rule (CFR section, DOL Fact Sheet, IRS publication).
- Implement the exact formula in code, with unit tests against worked examples from DOL or IRS publications.
- Surface applicable state-level exceptions (e.g., California daily overtime, restricted states for FWW).
- Cite every source on the result page so users can verify.
- Review annually — or sooner when rules change — against current guidance.
Editorial standards
Calculators and articles are written and maintained by the HRCalcs Editorial Team. We hold ourselves to four rules:
- Primary sources only. Every figure traces to the eCFR, a DOL fact sheet, an IRS publication, or the text of a court order — never to another blog. Each page links the source so you can check it yourself.
- Effective dates are always stated. Wage-and-hour thresholds change often, and outdated figures circulate widely. We date every number.
- Formulas are unit-tested. Each calculator is verified against the worked examples published by the DOL before it ships.
- Corrections are welcome and fast. If you find an error, email info@hrcalcs.com. We correct the page and note what changed.
What we are not. We are not attorneys and we do not practice law. HRCalcs explains what the published rules say and computes the arithmetic they prescribe. Applying those rules to a specific employee, contract, or jurisdiction is a legal judgment that belongs to qualified counsel.
