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.
