Hey Product Hunt 👋 I built Wanjaaro because every time I needed a specific calculator — Coast FIRE, a debt avalanche comparison, a mortgage points break-even — I'd end up on a site plastered with ads, forced to sign up, or missing the exact scenario I needed. So I built 70+ calculators covering growth, retirement, mortgages, debt, insurance, tax, budgeting, and investing — all in one consistent, fast interface. Everything runs 100% in your browser. No server ever sees your numbers. A few things I'm proud of: Niche tools most sites skip (Kelly Criterion, Coast FIRE, CD Ladder, Backdoor Roth IRA) Every calculator has history, CSV/Excel export, and shareable links Fully responsive, dark mode, zero tracking of your inputs Would love your feedback — especially which calculator you use most, and what's missing. Building the next batch based on what this community asks for.
