Is a 60/40 fee split sustainable?

It depends on one computable thing, not on which article you read: whether the 40 percent the practice keeps clears that clinician's share of overhead with margin left. A clinician collecting $10,000 a month leaves the practice $4,000. Against a $2,500 overhead share, that's $1,500 of margin and the split works; against a $3,600 share, it's $400 and the same split is quietly failing. The people who call 60/40 the sweet spot and the people who call it ruin are both describing real practices, with different overhead.

The sustainability condition

Practice keep = collections × the practice’s share of the split. The split is sustainable for a seat when that keep exceeds the seat’s overhead share plus its seat-borne costs (benefits, supervision, per-clinician software), with enough left to clear a real margin. Two lines of arithmetic, three numbers you either know or can build in an afternoon. Anyone arguing about 60/40 without those three numbers is arguing about their own practice, not yours.

Worked, both ways

At $10,000 of monthly collections: the practice keeps $4,000. Overhead share $2,500 and seat costs $400 leave $1,100, an 11 percent margin on the seat, above the 10 percent line the engine treats as thin. Same clinician, same split, but overhead share $3,600: the seat nets $0 after seat costs, and every one of those sessions runs at breakeven while looking fine on the revenue report. The split percentage never changed; the practice around it did.

What actually moves the answer

Three levers, in order of force: the clinician’s collections (a fuller caseload raises the keep with the same split), the overhead share (which is why mixed-hours rosters need an honest split of overhead, not a flat per-head charge), and only then the percentage itself. Owners reach for the percentage first because it is the visible number in the contract; the arithmetic says it is usually the third most powerful lever.

Where these numbers come from. The keep-versus-share condition is the engine’s seat-hurdle check, the thin line is its 10 percent margin flag, and both run in every group Snapshot.
