Cashcolt — Loan- Calculator
Personal Finance, Loan Calculator, Financial Planning
Cashcolt helps you understand and plan loan repayments — from a single mortgage to your whole household portfolio. Privacy-first: hosted in Germany, GDPR by design, no analytics cookies, no third-party scripts. Planning calculator only — no bank rate feed or broker workflow.
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! 🐴
