Choose your model
Start with the financial decision in front of you.
Each spreadsheet is designed for a specific job, with the structure already built so you can focus on assumptions and next steps.
FI Architect Spreadsheet
Best for: people who want to model a long-term FI path and keep full control of the file.
Test savings, spending, portfolio, and retirement assumptions in a reusable planning workbook.
Debt Payoff Planner
Best for: comparing snowball and avalanche strategies before committing to a payoff plan.
See the tradeoffs, choose an approach, and track progress without rebuilding the math yourself.
Money Map Budget Tracker
Best for: keeping budget categories and net worth visible in one repeatable monthly workflow.
Track the financial signals that help you stay oriented without turning every review into a new project.
