Re FIRE, I built this model some time ago: https://docs.google.com/spreadsheets/d/1E6TjJyowYowexkSvNV8tNCXNvtOGNeYfYUoCmTqFH0E/edit#gid=25893825 https://docs.google.com/spreadsheets/d/1E6TjJyowYowexkSvNV8t... Sorta more or less models and validates the 4% rule. And I have another sheet to track all my investments, etc using the GOOGLEFINANCE function to update with the market. I've also looked at using something like Plaid to import banking/credit card data, but it was all too complicated. So I now get a daily balance update via email that I scrape into my sheet using a Python script... Keeps me from needing to manually update the balances myself.
