AgentCalc

Hi Product Hunt! I’m JJ, the founder of AgentCalc. What started as a side project has grown into the world’s largest collection of online calculators — now over 3,000 and counting. From the serious (mortgages, health, business) to the whimsical (alien zoo habitat designer 🛸🐒), AgentCalc is built on the belief that every calculation deserves a calculator. Why we made this: People constantly Google “X calculator” — but most sites only cover finance or science. We wanted a single, clean, fast hub where you can calculate anything. Each calculator includes not just the math, but a clear explanation so you understand why the answer makes sense. Highlights: 📊 3,000+ calculators across finance, science, health, travel, and more. 🌍 Available in multiple languages (English, Spanish, Portuguese… more soon). ⚡ Lightweight, mobile-friendly, ad-supported but distraction-free. 🎨 Some calculators are even playful like a digital abacus or a terraforming planner. We’d love your feedback: 👉 Which calculators would you like to see next? 👉 How could we make AgentCalc more useful in your daily life? Thanks for checking out AgentCalc. We’re just getting started.
