Hey Product Hunt! 👋 I'm Nirmala, the builder of CalcNovaHub. I've been a software engineer for 20 years and built this because I was tired of calculator sites that just give you a number with no explanation. Every calculator shows the formula, walks through a real example, and explains common mistakes — the way a knowledgeable friend would. The feature I'm most proud of: 14 legal calculators covering workers comp, wrongful termination, overtime pay, and more. These searches get tens of thousands of monthly queries but the only results are law firm lead-gen pages. CalcNovaHub gives people the actual formula and a real estimate. Happy to answer any questions about the build!
