FIRE Tax Optimization Calculator
A sophisticated Federal tax planning calculator designed for the Financial Independence / Retire Early (FIRE) community with side-by-side comparison of up to three tax scenarios.
The Challenge
The Excel file was a sprawling multi-tab workbook where users had to manually copy formulas across scenario sheets, each tracking 15+ income categories with complex tax bracket calculations.
The Solution
We built a multi-scenario web application with card-based layouts for each tax scenario. Users can input income sources across all categories and instantly see calculated tax obligations.

The FIRE community embraced the calculator, generating over 10,000 unique users in the first six months through word-of-mouth sharing in financial independence forums and subreddits.
