Family office cost calculator

What does it really cost to run a family office your size?

Answer three sets of questions about the office, the portfolio and what the family keeps in-house. We return the annual cost of running it — by expense line, with the range we see in practice. No sign-up required.

The family office

Size, seat and the number of people the office actually serves. These four answers set the floor for everything that follows.

What you pay to invest usually exceeds what you pay to run the office.

The figure above covers people, providers, systems and structure. It does not cover manager fees, embedded fund costs, custody, trading, selection, or carried interest — and for most families those add up to more than the office itself.

We prepare that second analysis for your own numbers and send it by email. It is not shown here, and it is not something we publish.

Method

Where these figures come from, and why we give you a range.

Built from mandates, not surveys

The model reflects offices we have set up, reset and run alongside families since 2013 — compensation levels, provider fees and structural costs as they are actually paid, in each of the jurisdictions listed.

The range is the honest part

Two families of identical size can differ by half again in cost, on decisions no model can see: seniority of the hires, the standard the principal expects, how much the office absorbs that nobody wrote down. The spread carries that.

An estimate, not a budget

Use it to test whether what you pay today is defensible, and to frame the conversation with your principals. A real budget needs the office in front of us. We do not publish the underlying assumptions.

Questions we are asked

Before you trust a number.

For most single family offices the answer sits between 70 and 140 basis points of assets under management a year — a range wide enough that the average is of little use to you. Composition matters more than size: an office that keeps oversight, execution and accounting in-house costs a multiple of one that buys them.

If the number surprised you, that is worth an hour of a partner's time.

We take on a small number of mandates each year. Tell us what you are looking at and we will tell you what we see, including what you may not want to hear.
