Challenge
People underestimate how much taxes and account choice change long-term investing outcomes, and most online calculators are black boxes you have to take on faith. The brief was a tool that makes the math visible and provable, not a widget bolted onto a page.
Approach
We built a single-page app where every input recomputes instantly in the browser, with charts comparing taxable, Roth, and Traditional outcomes year by year. The calculation engine is its own tested module, checked for cent-level precision and verified against a reference model. Education sections and an FAQ explain the assumptions, with clear notes that it is not tax advice.
Outcome
A fast, self-contained tool that runs fully client-side with no backend to maintain. The math is transparent and test-covered, and it stays under the operator's control end to end.
