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calculator tools out there are either: ❌ US-only (useless for UK workers) ❌ Buried behind a sign-up wall ❌ Based on outdated formulas So I built something better.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?
