Hey Product Hunt! 👋 I built WorkCalc because I kept Googling the same freelance calculations — "how much should I charge per hour?", "how much will I owe in taxes?", "what should I put on this invoice?" — and every tool I found was either behind a paywall, required an account, or was built for W-2 employees, not freelancers. So I built a free suite that handles the math freelancers actually need: 1. **Rate Calculator** — factors in self-employment tax, business expenses, vacation days, and savings goals to find your true hourly floor 2. **Tax Calculator** — estimates both income tax + the 15.3% SE tax, with deduction support 3. **Invoice Generator** — fill it out, download as PDF, done. No account, no watermark 4. **Salary Converter** — for those "they offered me $X, what's that per hour?" moments 5. **Time Zone Converter** — compare 5+ zones at once (because remote work means 9am for you is... when?) 6. **Project Pricer** — scope out a project and get a quote-ready price Everything runs 100% in-browser. Your financial data never leaves your device. No signup, no paywall, no "upgrade to Pro." I also published a [Freelance Rates Report](https://workcalc.app/blog/freela...) with rate benchmarks across 30+ professions if you want to see how your pricing compares. Happy to answer any questions! What tools would you want added next?
