About ProCalc
Our Story
ProCalc started as a simple hobby project. Ayush Jain, a tech enthusiast based in Bangalore, India, found himself constantly building small calculators for personal use — whether it was figuring out SIP returns, estimating YouTube ad revenue, or projecting career salary growth. Spreadsheets worked, but they were clunky, hard to share, and not very fun to use.
So he decided to build something better: a clean, fast, and completely free website where anyone could run the same calculations instantly — no sign-ups, no downloads, no data collection. What began as a handful of personal tools quickly grew as friends, colleagues, and online communities started using and sharing them.
Today, ProCalc offers dozens of calculators and predictors spanning finance, the creator economy, artificial intelligence, business metrics, cryptocurrency, career planning, education, real estate, fitness, e-commerce, and more. And we're just getting started.
Our Mission
We believe that everyone deserves access to powerful financial and analytical tools — without paywalls, without complicated interfaces, and without giving up their personal data. Our mission is simple:
- Make complex calculations accessible — Whether it's compound interest, API cost estimation, or creator monetization, we turn intimidating math into instant, understandable results.
- Keep everything free and private — Every calculator on ProCalc runs entirely in your browser. We don't collect your data, we don't require accounts, and we never will.
- Empower better decisions — From a first-time investor calculating their SIP returns to a startup founder modeling break-even scenarios, we want our tools to help people make smarter, data-driven decisions.
