Why this path exists
Everything that makes accumulation simple stops being true when you start spending. Order of returns starts to matter. Taxes stop being an annual annoyance and become a sequencing problem. Health costs arrive as lumps, not averages. And the person operating the portfolio is, on a thirty-year horizon, guaranteed to become worse at operating it.
This is the longest path on the site because decumulation is where the most tools live and where reading without calculating is close to useless. Each tool appears immediately after the chapter that tells you what its output means.
