Hey Product Hunt community! 👋 I'm the maker behind CalcYield. As a builder and digital professional, I got tired of the friction caused by chaotic, bloated Excel sheets and ugly online calculators whenever I needed to make quick, critical financial decisions. I wanted something fast, private, and brutally efficient—like a premium, minimal financial terminal dedicated solely to my daily margins. So, I built CalcYield. It’s a lightweight, blazing-fast SPA designed around strict tactical grids, giving you zero-bloat engines to model your math instantly. For our launch today, we are shipping three core modules: 1. 📈 Ad Spend & ROAS Modeler – Model optimal ad budgets against conversion targets to forecast exact net margins. 2. 🧮 Compound Interest Engine – Simulate exponential portfolio growth across dynamic compounding intervals. 3. 🛡️ Freelance Rate & Tax Shield – Calculate your true hourly rate factoring in real overhead, safe dry-spells, and projected tax buffers. Plus, I built an interactive interface that lets you switch between a clean "Day Trade" view for high-focus daylight deep-dives and a dark "Night Vault" theme for private late-night forecasting. CalcYield is 100% free and ready to use right now. I would absolutely love to hear your feedback, feature requests, or thoughts on the design system! What financial engine should we build next? Let me know in the comments! 🚀
