Ideas a builder, maker or community group could start on:

  1. A web-based interactive calculator that models the net-pay impact of adjusting pre-tax vs. post-tax contributions based on the user's specific tax bracket.
  2. A decision-tree tool that asks users about their current age, expected retirement income, and current tax bracket to recommend an optimal contribution split.
  3. A simplified educational dashboard that visualizes the long-term growth difference between traditional and Roth contributions for specific salary levels.
