Hey Product Hunt community! 👋 I’m the maker behind NetMarginHub. As an e-commerce seller and freelancer myself, I always found it frustrating to calculate actual profit margins after platform fee hikes. It felt like every time I turned around, a marketplace slipped in another percentage cut. When I looked for online calculators to check my math, I noticed a frustrating trend: almost all of them forced me to enter my email address or create an account just to see the results. So, I decided to build a simple, clean solution for the community. NetMarginHub is a suite of hyper-accurate fee and profit calculators designed specifically for TikTok Shop, Etsy, Shopify, and freelancers. Why I made it this way: • 🚫 No Sign-Up / No Emails: You just open the page, type your numbers, and see your exact take-home pay instantly. • ⚡ Complete Transparency: It maps out the exact breakdown of referral fees, payment gateways, and hidden cuts. • 📱 Mobile Friendly: Check your margins quickly on the go. The site is 100% free with zero registration barriers. I want this to be a genuinely helpful utility bookmark for solo creators and independent professionals everywhere. I’d love to hear your thoughts, feedback, or any feature requests. What platform fees or specific local country taxes should I add to the code next? Thank you for checking it out! 🙏
