I'm Robert, the founder of CapitalCalcs. I built it because most financial calculators online are either buried in ads, locked behind a sign-up, or hand you a single number with no explanation of how they got there. I wanted one place where anyone could run the real numbers on an everyday money decision, for free, and actually understand the result. CapitalCalcs covers mortgages, auto and student loans, credit card payoff, high-yield savings, retirement and 401(k), debt payoff, home affordability, rent vs. buy, and more. Each calculator runs instantly in your browser, shows the math behind the result with clear charts, and links to a plain-English guide that explains what's going on. No sign-up, no paywall, and everything is framed as education, not advice. It's a solo project, so I'd genuinely value your feedback — what's confusing, what's missing, or which calculator you'd reach for first. And if there's a money decision you wish had a clear, free calculator, tell me and I'll look at building it. Thanks for taking a look. Robert
