About us

Built for real people, not accountants

PayCalcTools is a free collection of pay calculators built for workers, freelancers, and HR managers in the US and UK. We built these tools because pay calculations are genuinely confusing — and the stakes are real. Getting overtime wrong, setting your freelance rate too low, or not knowing your notice period can cost you money. Every calculator on this site is based on official employment law — the US Fair Labor Standards Act for American workers, and UK employment legislation for British workers. No guesswork. No outdated formulas. Just accurate, reliable calculations you can trust.

Common questions

FAQ

Are these calculators accurate?

Yes. Every calculator uses the official formulas set out in employment law — the US Fair Labor Standards Act (FLSA) for American workers, and UK employment legislation for British workers. We review and update every tool whenever the law changes. Results are for guidance — if your situation is complex, always confirm with your employer or HR department.
