Building Financial Tools Without Being a Financial Advisor

There's a specific discomfort in building a loan calculator, a compound interest tool, or anything touching money: the gap between "this shows you the math" and "this tells you what to do." I'm not a financial advisor, and every tool on Hilmost that touches money says so explicitly, not as legal boilerplate but because it's true.

The line I try to hold is: show the mechanism, never the recommendation. A mortgage calculatorcan show you exactly how much of your payment goes to interest in year one versus year twenty — that's just arithmetic, and arithmetic doesn't need a disclaimer to be trusted. What it shouldn't do is tell you whether a 15-year or 30-year mortgage is "better" for you, because that depends on things a calculator can't know: your job stability, your risk tolerance, what else you'd do with the difference.

This is also, honestly, the easier position to build from as a solo founder. I don't have to get financial advice right. I have to get the math right, and let people draw their own conclusions from numbers they can verify themselves. That's a narrower promise, but it's one I can actually keep.
