Hey Product Hunt! 👋 I built Calcnomics because I was frustrated with financial calculators that either require sign-ups, are cluttered with ads, or don't cover state-level taxes. The most-used calculator is the Paycheck Calculator — it shows your exact take-home pay after federal + state taxes for all 50 states. Just enter your salary and state, and you get a full breakdown instantly. A few things I'm proud of: → URL state — every calculation is shareable via link → Spanish version for all calculators (/es/ routes) → Schema.org JSON-LD on every page for better search visibility → Zero sign-up, zero ads Would love feedback on what calculators you'd want added next. What financial decisions do you find hardest to model?
