Hi Product Hunt! 👋
I’m the maker behind BizCalcLab.
As someone who has spent years navigating the tech and freelance space, I realized how often we rely on clunky Excel spreadsheets just to figure out simple things—like our true hourly rate, self-employment taxes, or break-even points.
Worse, most online calculators out there are either hidden behind expensive accounting SaaS paywalls or demand an email signup before giving you an answer.
So, I decided to build BizCalcLab to solve this. It’s a suite of 12 financial calculators specifically built for solopreneurs and small business owners.
A few things I’m proud of:
⚡️ Zero Frameworks: Built entirely with Vanilla JS for instant, lag-free calculations.
🔒 Privacy First: All math happens client-side in your browser. No data is stored or sent to any server.
💸 100% Free: No sign-ups, no paywalls. Just open and calculate.
I would absolutely love your feedback on the UX, the accuracy of the tools, or any requests for new calculators you'd like to see added next.
Thank you so much for checking it out! 🚀
