Hey Product Hunt 👋 I’m Marc — I built Cashcolt because I was tired of fragile Excel spreadsheets for real-world loans. Handling multiple credits, calculating complex "Sondertilgungen" (extra repayments), and answering the one big question — "When am I actually debt-free?" — shouldn't be a manual struggle. 🚀 Try it first (No signup required) Get a live amortization schedule + interactive chart while you type: 👉 cashcolt.kumiko.rocks/rechner 🛠️ What’s inside? If you create an account, you get 30 days of full access to all Pro features: Portfolio Dashboard: All your loans in one clean overview. Repayment Optimizer: Not sure where to put your extra cash? We show you which loan to pay off next to save the most interest. Goal Calculator: Set a date and see exactly how much you need to pay extra to hit it. Data Control: Full CSV exports whenever you need them. 🎯 What it is vs. what it isn't It IS: A high-precision planning tool for households and financial advisors. It ISN'T: A bank rate comparison site or a broker workflow. No "Open Banking" fluff — just pure planning power. 🔒 Built for Privacy & Tech Enthusiasts We built this with a "Privacy First" mindset: Transparent Tech Stack: Finance data on K3s + Pulumi, event-sourced loan writes in Postgres. GDPR by Default: Hosted in Germany, self-service account deletion, and zero analytics cookies. No Tracking Theater: Just a small team focused on building a great tool. 💬 I’d love your feedback! What features are still missing compared to your current spreadsheet? EU/DACH users: Does our amortization logic match the official statements you get from your bank? Thanks for checking us out — I’ll be here all day to answer your questions in the thread! 🐴
