Single Family Office vs Multi-Family Office (SFO vs MFO)
How dedicated SFOs and shared MFOs differ on cost, control, services, and the right asset threshold.
Single Family Office (SFO)
A private, dedicated organization that serves one ultra-wealthy family, with full control over staff, strategy, and privacy. Typically requires $250M+ in investable assets.
Multi-Family Office (MFO)
A firm that serves multiple families and shares infrastructure, talent, and best practices. Lower cost of entry — often viable from $25–50M per family.

| Annual operating cost | $3M – $10M+ | 0.25% – 1% of AUM |
| Control and customization | Full — bespoke to one family | Shared standards across clients |
| Privacy | Highest — closed organization | High but shared service model |
| Talent depth | Limited to in-house team | Pooled specialists across families |
| Speed to set up | 12–24 months | Weeks to a few months |
| Best for | Generational wealth, complex assets | Cost-efficient comprehensive services |
Verdict
Choose a Single Family Office when assets exceed roughly $250M and the family demands full control, deep privacy, and bespoke services. Choose a Multi-Family Office when you want comparable sophistication at a fraction of the cost — typically the right answer below $250M.
