How to Value a Multi-Family Office (MFO) in 2026

Let me draw a clear line before we go any further. A single family office— one family, their internal investment team, a general partnership that exists to manage the family's capital — is not a business. It's a cost center with no enterprise value. What we're talking about today is the multi-family office (MFO): a commercial business serving 15-200 ultra-high-net-worth client families, charging AUA-based advisory fees, and generating real cash flow that institutional buyers will write checks for.

The MFO market has been in a prolonged consolidation wave. Cerity Partners, Pathstone, Tiedemann Advisors (now Alti Global), Rockefeller Capital Management, Hightower, Mercer Advisors, and Creative Planning have all been active acquirers. The deals are getting richer, not cheaper, as RIA aggregators compete for a limited pool of high-quality MFO platforms.

The AUA Fee Model

MFOs get paid as a percentage of assets under advisement. Fee schedules are tiered — typically 100 basis points on the first $5-10M, declining to 30-50 bps on capital above $50M, with fully-negotiated flat fees above $250M. The blended yield across a mature MFO book usually runs 35-65 basis points.

For a $5B AUA firm with a 50 bps blended yield, that's $25M in annual advisory revenue. Subtract operating costs — advisor compensation, investment team, operations, compliance, technology, rent — and you typically get an EBITDA margin of 25-40% for well-run MFOs. Larger platforms with scale advantages can push EBITDA margins above 40%.

Unlike hedge funds or private equity firms, MFOs don't have carried interest or performance fees to muddle the valuation math. The revenue is clean, recurring, and priced on EBITDA multiples — much more like a traditional services business.

What RIA Aggregators Pay

MFO transactions in the current market price on EBITDA multiples that look rich compared to most other services businesses. The reason is simple: AUA-based fees are extraordinarily sticky. Ultra-high-net-worth clients don't shop around on price, they rarely fire their advisors, and client retention rates at established MFOs consistently run 95-98% annually.

Typical multiples by profile:

• Small MFO ($500M-$1.5B AUA): 7-10x EBITDA. Too small to be a platform for an aggregator, valuable primarily as an add-on.
• Mid-sized MFO ($1.5-5B AUA): 10-14x EBITDA. The sweet spot for aggregators looking for bolt-on acquisitions with regional presence.
• Platform MFO ($5-15B AUA): 13-17x EBITDA. Large enough to serve as a regional hub, with institutional infrastructure and brand.
• Marquee MFO ($15B+ AUA): 15-20x+ EBITDA. Rare, highly prized by aggregators competing to become the next Mercer or Creative Planning.

Public market data points help triangulate. Focus Financial Partners' 2023 take-private by Clayton Dubilier & Rice at $7B valued the holding company at roughly 14x EBITDA. Hightower's recapitalizations with Thomas H. Lee Partners have implied platform multiples in the 14-17x range. Creative Planning's minority sale to General Atlantic priced the firm at approximately 16-18x EBITDA. Mercer Advisors has changed hands multiple times at progressively higher multiples with each recapitalization.

Advisor Retention Is Everything

The central risk in any MFO acquisition is advisor flight. When a lead advisor leaves and starts their own firm, anywhere from 60-90% of their book follows them within 24 months. That's why buyers spend more time on employment agreements and non-solicitation clauses than on any other diligence item.

The gold standard deal structure includes:

• 5-7 year employment agreements for lead advisors with meaningful equity rollover (20-40% of proceeds rolled into buyer equity).
• 24-36 month non-solicitation covenants with liquidated damages provisions.
• Earn-outs tied to client retention measured at 12, 24, and 36 months post-close.
• Retention bonuses for second-tier advisors and relationship managers.

Deals without strong retention structures trade at 2-4 turns of EBITDA below the market. A $3B AUA MFO with rock-solid advisor lockups might transact at 13x. The same firm with advisors willing to leave might get 9-10x.

The best-run MFOs institutionalize client relationships so that no single advisor controls a client. Clients work with a team — a lead advisor, a tax specialist, an estate planning attorney, an investment strategist. When the relationship spans four people instead of one, advisor departures do much less damage. Buyers will pay premium multiples for team-based service models.

Client Quality Matters More Than Client Count

Two MFOs with identical $3B AUA can be worth very different amounts depending on how that AUA is distributed across the client base.

Client concentration is the single biggest risk factor. If your top 5 clients represent 40%+ of AUA, the loss of any one is a material event. Buyers discount concentrated books aggressively — often 20-30% off the standard multiple. Diversified MFOs with no single client above 3-4% of AUA command premium pricing.

Average client size drives operating leverage. An MFO serving 150 clients averaging $20M AUA produces the same $3B AUA as one serving 500 clients averaging $6M, but the former is dramatically more profitable. Fewer clients means lower servicing costs, fewer compliance touches, and higher EBITDA margins.

Multi-generational client relationships are the gold standard. Families you've worked with for 20+ years, where you're advising the second and third generation, are much stickier than newer relationships acquired in the last 5 years. Buyers love to see 60%+ of AUA in clients of 10+ year tenure.

Service complexity affects both stickiness and margin. MFOs that handle bill pay, tax preparation, estate coordination, philanthropic advisory, and alternative investment administration create much higher switching costs than investment-management-only firms. The deeper the service bundle, the higher the retention and the higher the multiple.

What Destroys Value

Founder-led client relationships with no succession. If the founding advisor personally manages 50%+ of the AUA and the next generation of advisors doesn't have established client relationships, the firm has no transferable franchise value. Buyers will require a 5-7 year founder lockup and still apply a concentration discount.

Outdated technology infrastructure. MFOs still running on Excel, legacy portfolio accounting systems, and manual reporting processes get valued lower because buyers know they'll need to invest $2-5M upgrading systems post-close.

Compliance issues. Past SEC enforcement actions, Form ADV disclosures of disciplinary history, or outstanding arbitration claims materially reduce marketability. Buyers either walk or require indemnities that eat into founder proceeds.

Non-fee revenue. MFOs that rely heavily on product commissions, insurance sales, or platform revenue shares get valued at much lower multiples than pure fee-only firms. The shift to fee-only has been a consistent industry theme and buyers pay premiums for fiduciary-only business models.

Weak operating margins. An MFO with sub-25% EBITDA margins signals that either pricing is too low or cost structure is bloated. Buyers will underwrite their own margin improvement plan and pay based on their target margin, not your current margin — usually to the seller's detriment.

How to Maximize Your MFO's Value

Institutionalize the service model. Move from founder-led relationships to team-based service. Every client should have a lead advisor, a backup advisor, a technical specialist, and a relationship manager. This single change can add 2-3 turns of EBITDA to your exit multiple.

Deepen the service bundle. Add tax preparation, estate coordination, and bill pay services if you don't offer them. Complex service bundles create switching costs that buyers value at a premium.

Clean up the client book. Politely transition out your smaller, less-profitable accounts 18-24 months before a sale. Buyers value average client size, not headcount.

Upgrade technology and reporting. Invest in modern portfolio accounting, client reporting, and CRM systems. Buyers pay for firms they don't have to rebuild.

Build multi-generational relationships. Actively engage the children of your current clients. Family education programs, next-gen networking events, and dedicated millennial advisors all help lock in the next generation of wealth transfer — which buyers will value at premium multiples.

The Bottom Line

Multi-family office valuations sit at the intersection of AUA mechanics and traditional services business analysis. The aggregators — Cerity, Pathstone, Mercer, Creative Planning, Hightower — will pay premium multiples for well-institutionalized MFOs with diversified client bases, locked-up advisor teams, and deep service bundles. They'll walk or lowball founder-dependent shops without succession plans.

The highest exit multiples I've seen went to firms where the founding generation spent 5-7 years building a team that could function without them. The clients felt the transition as a non-event. The advisors stayed. The AUA grew through the diligence period. That's what a 17-18x EBITDA outcome looks like. Everything else trades at a discount.
