Every plan in the register carried against what it closed, what it earned and what it costs to keep drawn, permitted and merchandised. A plan that closes four homes a year is not free to keep.
Reference scale, grade Derived. Not a forecast for your business. This figure describes what a decision of this shape has been worth at this scale of operation, drawn from the evidence named in section 02. No payback, return or year-one figure appears in this brief — no fee has been quoted, so those numbers cannot exist yet. They are computed against a signed quote and stated with the fee beside them.
A plan stays in the portfolio because someone still sells it and nobody is arguing to kill it. The cost of keeping it spreads across engineering, permitting, estimating, marketing and the studio, so no single line ever looks big enough to act on.
Killing a plan is a visible decision with a name attached. Keeping one is invisible and free.
The register tells you how many plans you carry. It does not tell you what the tail costs. The model joins closings and margin by plan to carrying cost per plan and sorts the portfolio.
The bottom of that list is often a quarter of the plans and a rounding error of the closings. Retiring it releases estimating and studio capacity before it releases any cash.
The rest of this model — the data sets it runs on, the cause split, the working behind the reference figure and a sample output — goes out by email. Two fields, nothing else.
