Do You Need a Single Family Office, or Is That Overkill?
A Family officeA private organisation that manages the money and affairs of one wealthy family (single-family) or several (multi-family). (SFO) is a private company that runs one family's money and affairs. Running one costs roughly $1m a year or more, whatever the family's wealth. For most families, the sums only start to work above about $250m of investable assets, unless complexity or a wish for control and privacy justifies it.
Families usually reach this question from a feeling, not a calculation. Their advisers don't talk to each other, nobody has the whole picture, and the family wants control. All fair. But an SFO is an operating business, so the question to answer is whether your family's complexity justifies running one.
What does an SFO actually cost?
Cost is driven by headcount, not by assets. You're hiring a small company's worth of people, and that's where the money goes.
A minimal professional team looks like this:
- A principal executive or CIO (chief investment officer, the person who runs the investments) with genuine investment credibility.
- An operations and reporting lead.
- Administrative support.
- Outsourced legal, tax, audit and custody (custody means a bank or firm holding your assets safely).
Then add premises, technology (consolidated reporting, portfolio and document systems) and insurance, including D&O (directors' and officers' liability cover). Add regulatory permissions where investment advice is given to family members, plus audit and payroll administration.
In major financial centres, that minimal team is rarely under $1m a year fully loaded. "Fully loaded" means salaries plus everything else it costs to employ them. A more complete office, with an investment team, in-house counsel and direct-investment capability, runs to several million.
Pay is the biggest line. It's competitive with the market the family is hiring from, because you're bidding against banks and funds for the same people.
Where does the break-even point sit?
Compare the SFO with its alternative. A well-negotiated multi-family office or private-bank discretionary arrangement (where the bank makes investment decisions for you) typically runs 0.4% to 0.8% of assets all-in, falling with scale.
That's why the conventional threshold sits somewhere above $250m of investable assets. Families below it who run an SFO are usually paying for control and privacy rather than efficiency. That's a perfectly valid purchase. Just make it knowingly.
When does complexity justify it?
Some families below the usual threshold genuinely need an office because of what they own, not how much. There are five common triggers:
- Operating businesses still held by the family, needing board representation and oversight.
- Direct investments and co-investments (buying into companies or deals directly). They need sourcing, diligence and monitoring, and they are the single biggest driver of real headcount.
- Multi-jurisdiction property portfolios, with management, tax filings and capital projects to look after.
- Large family membership across several countries, which brings distributions, education funding and governance requirements.
- Philanthropy run as a programme rather than as donations.
Compare two families. One has $150m in liquid securities and needs far less. The other has $150m spread across four operating businesses in three countries.
Where are the grey areas?
Most of this article is arithmetic, but a few points depend on judgement or on rules that vary by country. They're worth knowing before you commit.

What are the options between "nothing" and an SFO?
You don't have to pick between doing nothing and building a full office. There are four middle routes.
title: The four middle routes compared
| Model | What it is | Trade-off |
|---|---|---|
| Embedded office | One trusted professional (a family CFO) coordinating outside providers, with no separate entity. Costs a single salary. | Solves the coordination problem, which is often the real complaint. |
| Multi-family office | Institutional infrastructure shared across families. | Loses bespoke attention; gains reporting, consolidated custody and negotiating power. The right answer for a large share of families in the $50–250m band. |
| Virtual family office | A coordinator plus a deliberately assembled panel of specialists, with clear reporting lines and one consolidated report. | Lower fixed cost, but you depend heavily on the coordinator. |
| Hybrid | A small internal team for governance, reporting and direct investments, with public-market management fully outsourced. | In our experience, the most common landing place for families between $150m and $400m. |
What must an SFO have to be worth it?
If you do go ahead, the office fails without these five things.
- A written investment policy statement, approved by the family, setting out objectives, constraints, liquidity needs and permitted asset classes. Without it, the CIO is guessing and the family is unhappy in every drawdown (a fall in the portfolio's value).
- Governance separated from ownership. That means a family council or board with defined decision rights, so the office isn't run by whoever calls most often.
- Independent oversight. External audit and independent performance reporting. Self-reported performance is how family offices lose money without anyone noticing.
- Segregation of duties in cash movement. Most family office fraud is one person controlling both the instruction and the reconciliation (the check that the books match the bank).
- Succession and key-person planning for the office itself.
What if it doesn't work out?
Almost nobody asks this up front. Employment contracts, leases, regulatory permissions and custody arrangements all cost money to unwind. Dismantling an office is also publicly visible within the family, which makes for awkward Christmases.
So decide in advance what the review point looks like. A three-year assessment against defined objectives is typical.
FAQs
What is the realistic minimum for an SFO?
Below roughly $250m of investable assets, the economics rarely work. The exceptions are a family deliberately buying control and privacy, or one with unusually high complexity.
Can an SFO be based offshore?
It can, but the office must be where the people actually are. A "Dubai family office" run from London is a substance and tax problem, not a saving.
Do we need regulatory permissions?
Often yes. It depends on the jurisdiction and on whether the office advises or manages for family members and related entities. Several jurisdictions have specific family-office exemptions with conditions.
How do we pay people?
Competitively, with a long-term incentive tied to the family's objectives rather than to short-term performance. Underpaying produces turnover, which is the most expensive outcome.
