Updated August 3, 2026. Quick answer: there is no net-worth number that switches the answer on, and the figures circulated as thresholds are marketing conventions rather than findings. The defensible version is a range with conditions: below roughly the eight-figure mark almost nobody is served by a single-family office, the multi-family route is where most families who genuinely need the function land, and above it the deciding variable is still what the balance sheet looks like, not what it totals.
Why the published thresholds do not agree
Because they are describing different things. Some quote the level at which a single-family office is cost-rational against buying the same functions; some quote the minimum a particular multi-family office accepts; some are simply repeating the last number they read. None of them is measuring your situation, and the spread between the commonly quoted figures is wide enough to be useless as guidance.
The variables that move the answer more than the total
- Is there an operating business? This is the single biggest swing factor. It brings tax, succession, governance and liquidity problems simultaneously.
- Is the wealth concentrated or diversified? A concentrated position is a risk-management project, not an administrative one.
- How many households and jurisdictions? Each one multiplies filings, and cross-border adds a whole compliance layer.
- Illiquid holdings? Property, private funds and capital calls generate continuous administration regardless of total value.
- How many adults must agree? Governance cost scales with people, not dollars.
The three rungs, in the order families actually climb them
One: a coordinated adviser relationship, where one party owns the whole picture. Two: a multi-family office, buying the function without employing it — where most families who need this genuinely belong. Three: a single-family office, which is starting a company. Families usually discover they needed rung two while shopping for rung three.
A better question than the threshold one
Not “have I got enough,” but “what is currently going wrong.” Missed filings, unexecuted estate documents, a trust nobody funded, siblings negotiating without a forum, a concentrated position nobody has hedged — those are the symptoms that justify the structure. Absent them, the number on the statement is not itself a reason.
Start one rung lower than you think, and make them put it in writing.
Most families shopping for an office discover they wanted coordinated advice. Ask two or three firms what they would take responsibility for at your asset level, in writing, and what would remain yours to run.
Before you start, what actually happens. The matching service is run by WiserAdvisor, an independent advisor-matching company. It opens on their site, asks for your ZIP code and a few questions, and matches you with 2 to 3 vetted advisors. It is free to you.
WiserAdvisor states the service is built for portfolios of $250,000 and above. By submitting, you consent to emails, phone calls and text messages from WiserAdvisor and up to three advisors, so expect to be contacted. Clear Money Guide is paid when you complete the form, whether or not you ever hire anyone.
Compare fees, scope, conflicts, credentials and fiduciary duty before you hire anyone. This is not the only way to find an adviser, and it is not a family-office search.

What the tier below actually charges, and what a written quote should contain: private wealth management fees. The same question one rung down: are private banks worth it. And the structural piece almost every family at this level gets wrong: what you give up either way.
