Use Coastful purely offline. ---------------------------------------- FREE - the personalized calculator PERSONALIZED SAFE WITHDRAWAL RATE A real-return SWR built from your actual asset mix - not a generic 4%. Sample portfolio: Base 4.0% becomes Personal 3.1%, a more honest FIRE number. Set an expected return per asset and tune your own inflation assumption.
