- Each line follows a driver, such as headcount, number of accounts or number of jurisdictions.

- This page quotes no prices, because costs depend on each family.
A single family office budget is the sum of 5 lines, and each line follows a driver the family controls. This guide shows what each line holds, how to measure the total against assets and how to build a budget in 4 steps, as of October 2026. It sits under the single family office guide and serves families in Singapore, ASEAN and Hong Kong. This page is general information, not legal, tax or investment advice.

What are the main lines of a family office budget?
The budget has 5 lines: people, premises and technology, professional fees, insurance and compliance, and a reserve for projects. Together they cover everything from the salary of the head of office to the audit of the accounts. Naming the lines first prevents surprises, because each cost then has a place on the page.
A sixth group sometimes appears in practice: family services such as travel, events or philanthropy administration. Treat it as a separate budget with its own owner. Keeping family services apart from office operations makes it easy to see what the office itself costs and what the family chooses to ask of it.
How do people costs shape the single family office budget?
People form the largest line in most offices. The line holds salaries, bonuses, benefits, recruitment, training and the cost of work passes for staff who relocate. Each role adds a full set of costs, so the number of roles drives the line more than any single salary does.
Plan for the whole cycle: recruitment fees, the first months of onboarding, annual reviews and replacement when someone leaves. A budget that counts only salaries understates the line. Adding a modest allowance for turnover gives the family a more realistic view and avoids mid-year corrections.
Which premises and technology items does a family office budget need?
Premises can range from a shared desk to a private floor, and the choice follows the team size and the privacy the family wants. Technology covers reporting software, data feeds, secure storage, communication tools and devices. Each item has a licence fee, a setup cost and a support cost.
Security belongs in this line. Access control, encrypted backups and staff training protect records that the whole family relies on. Families that review the technology list every year tend to drop unused tools early, and the line stays proportionate to the workload.
How do professional fees and compliance enter the family office cost?
Professional fees cover legal, tax, accounting, audit and sometimes investment advice. The number of jurisdictions and entities drives most of this line, since each entity needs filings, and each filing needs a preparer. A family with 2 companies and 3 accounts has more filings than one with a single account.
Insurance and compliance sit alongside. Insurance protects the office, its directors and its data, while compliance covers records, anti-money-laundering checks and regulatory filings that apply to its activities. Ask your advisers for a calendar of recurring items so the budget reflects the real year.
How can a family measure the cost of a single family office against its assets?
The cost ratio divides the annual budget by the assets the office serves. The ratio tells you how much the structure takes for each unit of wealth it coordinates. Because fixed costs spread across more assets as an estate grows, the ratio usually falls with scale.
Compare the ratio with the fee quoted by shared providers for the same functions. If the private ratio is higher, check whether the extra cost buys control, privacy or coverage that the family values. The comparison turns a feeling about cost into a number that you can discuss.
How can a family keep family office fixed costs proportionate?
Several choices keep fixed costs in line with the workload. Outsource a function with a seasonal peak, such as tax preparation. Share premises or services with a related business. Hire in phases, so each new role starts when a task repeats and a backlog is visible.
Review the budget against activity twice a year. A function that grows deserves a hire, and a function that shrinks deserves a smaller allocation. The family keeps the coordination it needs, and the office stays flexible when the estate changes.
How do you build a 3-year single family office budget?
Use 4 steps. First list the functions the office must deliver. Second assign each function to a person, a provider or both. Third price each item from quotes you collect. Fourth add the reserve and write the assumptions beside the total, so anyone can see what would change it.
Project the figures over 3 years. Mark when each hire starts, when systems renew and when filings peak. A 3-year view shows the family when the budget rises and why. It also gives you a baseline for later comparison with a shared or virtual option.
How can a family test its family office budget with EQOS Asia?
Once the budget exists, test the decision behind it. The EQOS Asia pricing page lists formats that score a decision across 9 life dimensions, including the capacity of the family to carry a commitment over time. The score sits next to your numbers and does not replace them.
A free 30-minute pre-diagnostic helps you frame the question (EQOS Asia private page, 2026). Book it through the contact page and bring your draft budget. You leave with a view on the format that fits and the assumptions to check first.

Frequently asked questions
What does a single family office budget include?
It includes 5 lines: people, premises and technology, professional fees, insurance and compliance, and a reserve for projects. People form the largest line in most offices. Each line follows a driver such as the number of roles, entities or jurisdictions, which lets the family adjust it as needs change.
How do I compare the cost of a private office with a shared one?
Compute the cost ratio: the annual budget divided by the assets the office serves. Then compare it with the fee quoted by a shared provider for the same functions. If the private ratio is higher, check what extra control, privacy or coverage the family receives for it.
Why does this page quote no prices?
Costs depend on the city, the team, the number of entities and the choices of each family, and published averages can mislead. The page gives a method, so you can collect your own quotes and build a budget that reflects your situation as of October 2026.
How often should a family review the office budget?
Review it against actual activity twice a year and rebuild the 3-year projection annually. A growing function may justify a hire, a shrinking one a smaller allocation. Regular reviews keep the structure proportionate to the estate it serves.
