CalcFi

CalcFi is a free financial decision platform with 330+ calculators for money decisions like mortgages, debt payoff, taxes, salary, retirement, savings, business finance, and cost of living. I built it to solve a simple problem: most calculator sites give users one isolated number, but people usually need to understand what that number actually means. CalcFi combines source-cited financial formulas, live data, AI-powered result analysis, and cross-calculator Financial Picture analysis so users can connect income, debt, housing, tax, savings, and retirement decisions into one clearer view. Users can run calculators for free, get AI explanations of their results, save outputs, compare scenarios, and see how multiple money decisions affect each other. The goal is to make financial math easier to understand before making a decision. The site is built as a fast web app with a large calculator library, SEO-focused calculator pages, live financial data integrations, AI result analysis, and a clean user interface designed for quick decisions.
