CalcFi

What is CalcFi?

CalcFi is a free financial calculator platform built for clarity and trust. Every formula cites a federal or primary source — BLS, BEA, Census, FRED, Freddie Mac PMMS — with visible methodology, transparent provenance, and zero fabricated advice. The library covers 90+ calculators across mortgage affordability, paycheck take-home, retirement readiness, tax brackets, debt payoff, salary comparison, cost of living, and more. State and city variants auto-inject local tax rates, median rents, and regional price parities so outputs reflect your actual market, not a national average. No accounts required, no paywalls, no affiliate push — results, PDF reports, and email exports are free. Embeddable widgets let anyone drop a calculator into their own site. Built for individuals, advisors, creators, and teachers who need fast, sourced, honest numbers without signing up or being sold something. Editorial standards, methodology, and corrections process published openly. Reviewed by the CalcFi Edi
