Hey Product Hunt! 👋 I built this tool because I was planning my own relocation and couldn't find a simple way to compare how different countries' tax rules would affect my investment portfolio. Every calculator I found was either too complex or focused on a single country. Portfolio Tax Simulator lets you test your actual holdings (US ETFs, UCITS funds, bonds, etc.) and see your real after-tax returns across multiple countries. It's free to use, no signup required. What's working: ✅ Real-time calculations for 6+ countries ✅ Multi-currency support ✅ Side-by-side comparisons What I'm working on: Adding more countries (open to requests!) Custom asset support Historical tax scenario analysis I'd love your feedback - especially if you're an expat or thinking about relocating. What features would make this more useful for you? Thanks for checking it out!
