PayCalcTools
Free pay calculators for workers & employers — US & UK
PayCalcTools gives workers, freelancers & HR managers free instant pay calculators — overtime, shift differentials, freelance day rates & notice periods. Built on official US FLSA & UK employment law. No sign-up. No paywall. Just the right number.
Hey Product Hunt! 👋
I built PayCalcTools because pay calculations are genuinely confusing
— and getting them wrong costs real money.
Most free calculator tools out there are either:
❌ US-only (useless for UK workers)
❌ Buried behind a sign-up wall
❌ Based on outdated formulas
So I built something better. PayCalcTools covers both US federal law
(FLSA) and UK employment legislation — completely free, no account
needed, no data stored.
Right now you can calculate:
⚡ Overtime pay (including California daily OT rules)
⚡ Shift differential pay (with overtime overlap handled correctly)
⚡ Freelance day rates (accounts for tax, holidays & dry months)
⚡ UK notice periods (statutory + contractual)
More calculators launching soon — holiday pay, redundancy, salary
sacrifice, IR35, take-home pay.
Would love your feedback — especially from anyone in HR or who
freelances. What calculator would you find most useful next?
