Creator
Built by Luis Gonzalez
I'm a web developer who enjoys making financial calculations easier to understand and use. I started building tax and finance tools after realizing how hard it was to get a straight answer from existing calculators — too many asked for an email before showing results, or hid the math behind a black box.
TaxFacet grew out of that frustration. Every calculator shows its formula, works instantly without sign-up, and covers real scenarios across all 50 states. I also built Retirement Budget, a free retirement planning site with calculators, state comparisons, and a Plan Builder.
My goal with both sites is the same: make the numbers approachable so you can ask better questions and make decisions that fit your life.
