Drawdown Projection · measuring whether the water runs deep enough
Soundings is the decumulation companion to Landfall. Where Landfall projects the portfolio growing, Soundings projects it being drawn down: you stop adding and start living off it. Set a withdrawal as a fixed monthly figure or a portfolio percentage (each shows the other), and see whether the portfolio sustains the draw, keeps growing despite it, or runs aground, and if so, in which year.

Withdrawals are drawn proportionally across the pool's assets each month, so the mix holds roughly steady. Returns are your assumptions, compounded monthly. A portfolio earning more than you draw survives; drawing faster than it earns depletes it. This is deterministic: it excludes volatility and sequence-of-returns risk, which matter most in early retirement.
