How to Value a Functional Medicine Practice in 2026

Functional medicine practices trade at the highest multiples in small healthcare. I've seen well-run FM clinics sell at 4-5x SDE — double what a comparable primary care practice would fetch — and the reason is straightforward. These are premium cash-pay businesses with subscription revenue, high average patient values, supplement retail, and an increasingly professionalized buyer pool.

Here's how these practices actually get priced, and what separates the clinics that sell at 3x from the clinics that sell at 5x.

Why Functional Medicine Commands Premium Multiples

A typical insurance-based primary care practice generates $200-350 per patient visit, sees 20-30 patients per day, and runs at 8-14% net margin after billing overhead and write-offs. The buyer pool is other PCPs and hospital systems, and multiples sit at 3-5x EBITDA at the practice level.

A functional medicine practice looks completely different. New patient intakes run $450-1,500 depending on the market and the physician's credentials. Follow-up visits are $200-500. Patients often sign up for 6-12 month programs with upfront commitments of $3,000-$12,000. Add supplement and lab markup, and average revenue per patient per year routinely hits $2,500-$6,000 — three to five times what a PCP captures.

That revenue profile supports higher multiples. Independent FM practices under $2M in revenue typically sell at 3.0-5.0x SDE. Larger practices with institutional-quality management and $500K+ EBITDA can transition to EBITDA-based pricing at 5-8x, with PE-backed platforms paying at the high end for tuck-in acquisitions.

The Multiples Breakdown

• 3.0-3.5x SDE: Solo MD or DO, cash-pay but no membership structure, limited supplement revenue, owner sees every patient.
• 3.5-4.0x SDE: Solo physician with a nurse practitioner or health coach leveraging patient time, some membership revenue, supplement dispensary at 15-25% of revenue.
• 4.0-4.5x SDE: Multi-provider practice, established membership program generating meaningful MRR, supplement revenue 25%+, lab markup as a real line item, retained staff.
• 4.5-5.0x SDE: Premium practices with strong MRR from memberships, documented clinical protocols, transferable physician brand, and growth trajectory. These are the practices institutional buyers compete for.

A practice generating $1.2M in revenue with $380K SDE will typically sell somewhere between $1.1M and $1.9M. The range is wide because the quality differences between FM practices are larger than in almost any other healthcare category.

The Membership Model: Why It Matters So Much

The single biggest driver of premium multiples in functional medicine is the membership or concierge structure. Practices that charge $200-500/month for ongoing access — typically including a set number of visits, messaging access, and discounts on supplements and labs — generate genuinely recurring revenue that buyers value like subscription businesses in other industries.

A practice with 300 active members at $300/month is generating $1.08M of annual recurring revenue before a single lab or supplement sale. That MRR is what pushes the multiple from 3x to 5x, because buyers can underwrite it directly. Pull a report from your EHR or membership platform showing active member count, MRR, churn rate (monthly and annual), and average member tenure. That report is the single most important document in your sale.

If you're not running a membership model, you should seriously consider adding one 18-24 months before sale. Even partial conversion — say, 40% of your active patients on a membership — materially changes your exit value.

Lab Partnerships and Markup

Functional medicine practices work with specialty labs — Genova Diagnostics, DUTCH (Precision Analytical), Vibrant America, Diagnostic Solutions, Great Plains, Doctor's Data, SpectraCell, and others. Most practices mark these labs up 50-200% from their direct-bill cost and either bill the patient directly or bundle labs into their program pricing.

Lab markup is real revenue and buyers pay for it, but they want it structured cleanly. Key questions:

• Is markup legal in your state? Several states (California, New York, Pennsylvania, and others) restrict or prohibit lab markups. Practices that have been quietly doing it anyway face real exposure at sale.
• Is it transparent to patients? Bundled program pricing that includes labs is cleaner than separate markup line items.
• Are the direct-bill agreements transferable? Most specialty lab direct-bill accounts are tied to the physician's NPI or a specific corporate entity. Buyers need these reassigned at closing.

A well-structured lab program contributes 10-25% of revenue at 50-60% margin in many FM practices. Done wrong, it becomes a diligence problem that kills the deal.

Supplement Revenue (and Why It's Different Here)

Like naturopathic clinics, FM practices generate meaningful supplement revenue through Fullscript, Wellevate, or direct dispensary sales. But in functional medicine the numbers are typically larger because average patient spend is higher and protocols often include 5-10 supplements per patient.

A mature FM practice doing $1.5M in clinical revenue will often generate $300K-$600K in supplement sales on top at 35-45% margin. Buyers treat the auto-ship portion as recurring revenue and pay accordingly. The walk-in portion is treated as transactional and discounted. Break these out clearly in your financials before going to market.

Who Buys Functional Medicine Practices

The buyer pool is more sophisticated than for any other small healthcare category I cover. Realistic buyers include:

• Other MD/DO functional medicine physicians looking to own or expand. SBA 7(a) loans work for deals up to ~$5M enterprise value.
• PE-backed integrative medicine platforms actively rolling up FM practices with $500K+ EBITDA. Expect 5-7x EBITDA with 20-30% equity rollover and 3-5 year earnouts.
• National concierge medicine operators occasionally adding FM capabilities.
• Regional integrative health groups building out multi-specialty platforms.

Unlike acupuncture or TCM, institutional buyers are real and competitive in this space. If your practice is large enough to attract them, run a proper process with a healthcare-focused M&A advisor. The difference between a negotiated sale to a single buyer and a competitive process among institutional acquirers is often 25-40% in total consideration.

What Kills Value in FM Practices

The physician brand IS the practice. Many FM practices are built around a physician who has a book, a podcast, or a social media following. Patients come specifically for that person. If the brand doesn't transfer — and it usually doesn't — buyers price in 30-50% attrition and discount accordingly. The fix is adding associate providers 18-24 months before sale and transferring patient relationships deliberately.

Weak membership retention. If your membership churn is above 3-4% per month, your MRR isn't really recurring — it's a leaky bucket. Buyers will discount MRR with high churn down to near-zero value. Fix retention before you sell.

Compliance grey areas. Off-label prescribing, compounded hormones without proper pharmacy relationships, peptide prescribing in states where it's restricted, IV therapy without clear standing orders, lab markup in states that prohibit it — all of these show up in diligence and either kill deals or force big price reductions. Clean up compliance before you go to market.

Books that mix personal and practice expenses. Physicians running S-corps or LLCs often run car leases, travel, continuing education, and personal supplements through the practice. Add-backs are fine and expected, but they need to be documented and defensible. SDE add-backs that can't be proven get rejected in diligence.

Preparing Your FM Practice for Sale

The 24-month playbook for maximizing FM practice value is intensive but rewarding. Launch or grow a membership program with clear MRR reporting. Bring on at least one associate provider — NP, PA, or another physician — to prove the practice runs without you. Clean up any compliance grey areas, especially around lab markup, compounded medications, and IV protocols. Get professional financials prepared: three years of reviewed P&Ls, clean add-back schedules, and separate reporting for clinical, membership, supplement, and lab revenue.

Finally, start conversations with institutional buyers 12 months before you want to close. These processes take time, and the diligence is heavier than a typical small healthcare deal. But the payoff is real — I've seen FM practices sell for 40-60% more through a competitive process than through a negotiated sale to the first interested buyer.

The Bottom Line

Functional medicine is the highest-multiple category in small healthcare because the business model is genuinely differentiated: cash-pay, recurring through memberships, high patient lifetime value, meaningful ancillary revenue, and a growing institutional buyer pool. A $1.5M FM practice with $450K SDE can reasonably sell for $1.6M-$2.2M, which is structurally higher than what any insurance-based primary care practice could achieve. Getting to the top of that range requires treating your practice as a business from day one and preparing it for sale years in advance.
