A concierge practice can spend $800 to acquire a member and still be doing fine. A med spa spending $800 to acquire a facial client is on fire. Same number, completely different meaning, and that gap is exactly why most concierge medicine patient acquisition cost benchmarks you find online are useless to you.
The number that matters isn’t what you paid per lead. It’s what you paid per member, measured against what that member is worth over the years they stay enrolled. Concierge membership is a recurring-revenue business wearing a stethoscope. And recurring-revenue businesses get to spend more up front than anyone selling a one-time service.
Here’s the short version: A reasonable concierge medicine patient acquisition cost is one that stays under roughly one-third of a member’s first-year membership revenue, and pays itself back within 12 months. For a practice charging $2,400/year, that means a CAC in the $400 to $800 range is defensible. At $5,000/year memberships with multi-year retention, CAC north of $1,200 can still be profitable. The panel cap matters more than the CAC number.
This checklist walks you through what you need to measure before you can even say whether your acquisition cost is reasonable, then gives you a scoring framework at the end. Work through it with your actual numbers open in front of you. Guessing defeats the point.
Who This Checklist Is For (And When to Run It)
You should run through this if you’re a concierge or membership-model practice (concierge internal medicine, DPC, functional medicine with a membership tier, executive health) and one of these is true:
- You’re spending on marketing and can’t confidently say what a member costs you to acquire
- An agency just quoted you a monthly retainer and you want to know if the math works before you sign
- Your panel isn’t filling as fast as your pro forma assumed
- You’re about to convert from insurance-based to concierge and need to model the transition
This is not for you if you haven’t launched yet and have zero conversion data. In that case, skip to the modeling section and build assumptions instead. You’ll replace them with real numbers in six months.
One thing worth saying up front, because you’ve probably been pitched otherwise: nobody has a credible published industry-wide CAC benchmark for concierge medicine. The segment is small, practices don’t share data, and the ones that do are mostly large national brands with economics nothing like a solo or three-provider practice. Anyone who hands you a confident “the industry average is $X” number pulled it from a blog post that pulled it from another blog post. What follows are ranges we see in practice plus the math that lets you build your own benchmark, which is the only benchmark that matters.
Checklist One: The Numbers You Need Before You Can Benchmark Anything
You can’t evaluate acquisition cost without the denominator. Most practices track spend and stop there. Get these nailed down first.
- [ ] Fully loaded monthly marketing spend. Not just ad spend. Include agency fees, website hosting, CRM, the part-time coordinator’s salary allocated to marketing, event sponsorships, print. Verify it by pulling three months of card statements and categorizing every line. Most practices undercount by 30 to 40 percent because they forget internal labor.
- [ ] New members enrolled per month, by source. Not inquiries. Not consults. Signed, paid members. If you can’t attribute a member to a source, that member goes in an “unknown” bucket and you note how big that bucket is. If unknown is over 40 percent, your attribution is the problem, not your CAC.
- [ ] Annual membership fee, per tier. If you run couples pricing, family pricing, or an executive tier, calculate a blended average rather than using your headline rate. The blended number is usually lower than practice owners assume.
- [ ] Average member tenure in years. If you’ve been open long enough, calculate actual attrition. If not, use your annual renewal rate and take the inverse. An 85 percent renewal rate implies roughly 6.7 years of average tenure. A 70 percent rate implies about 3.3. That difference changes everything about what you can afford to spend.
- [ ] Ancillary revenue per member per year. Labs, supplements, IV therapy, aesthetics, cash-pay procedures. In functional medicine practices this can rival membership revenue. Leaving it out makes your CAC look worse than it is.
- [ ] Your panel cap and current fill rate. How many members can each provider hold, and how full are you? This is the number that overrides everything else, and I’ll explain why in a minute.
Verification test for this whole section: can you produce a single number for cost per enrolled member for last quarter, and defend where every input came from? If you’re reaching for estimates on more than one line, you’re not ready to benchmark.
What Counts as a Reasonable Concierge Medicine Patient Acquisition Cost?
Now the math. Lifetime value for a concierge member is straightforward compared to most healthcare verticals, because the revenue is contractual and recurring.
LTV = (annual membership fee + annual ancillary revenue) × average tenure in years × gross margin
Gross margin in a concierge practice is high but not 100 percent. Use 60 to 70 percent as a working assumption unless your accountant has a better number, since panel size caps how much incremental cost each new member adds.
The benchmark most membership businesses converge on is LTV:CAC of 3:1 or better, with CAC payback inside 12 months. Payback matters more than ratio for a practice that’s cash-flow sensitive, because a 5:1 ratio that takes four years to pay back will still strangle you.
| Annual membership fee | Assumed tenure | Rough LTV (membership only, 65% margin) | Defensible CAC range | Payback window |
|---|---|---|---|---|
| $1,500 (DPC-style) | 4 years | ~$3,900 | $250 – $500 | 2-4 months |
| $2,400 | 5 years | ~$7,800 | $400 – $800 | 2-4 months |
| $3,600 | 5 years | ~$11,700 | $600 – $1,200 | 2-4 months |
| $5,000 | 6 years | ~$19,500 | $900 – $1,800 | 2-4 months |
| $10,000+ (executive health) | 6 years | ~$39,000 | $1,800 – $4,000 | 4-6 months |
Those ranges assume membership revenue alone. Add meaningful ancillary revenue and the top of each range moves up. A functional medicine practice where the average member spends another $1,800/year on labs and protocols is running a different business than a pure DPC practice at the same membership price.
Notice what’s missing from that table: cost per lead. Cost per lead is a vanity metric in this category. Concierge sales cycles run long, the consult is the real conversion event, and a $40 lead that never shows up to the meet-and-greet costs you more than a $200 lead who enrolls. Benchmark cost per enrolled member. Everything upstream is diagnostic, not decisive.
Checklist Two: Auditing Where Your Acquisition Cost Actually Goes
Once you know your number, find out what’s driving it. Run these checks channel by channel.
- [ ] Separate paid, organic, and referral CAC. Blended CAC hides everything. A practice with a $600 blended CAC might be running $250 on referrals and $1,400 on paid search. Verify by tagging each enrolled member with a primary source at intake, asked by a human, not a dropdown on a form.
- [ ] Calculate your physician-referral CAC honestly. Referral relationships feel free. They’re not. Lunches, time, a liaison’s salary. Divide that cost by referred enrollments. Practices we’ve worked with are often surprised that their “free” referral channel costs more per member than their Google Ads do, and that’s fine, because referred members tend to stay longer. Just know the number.
- [ ] Check consult-to-enrollment conversion rate. This single metric moves CAC more than ad spend does. If you’re converting 40 percent of meet-and-greets and could get to 60 percent, your CAC drops by a third without touching the marketing budget. Verify by counting scheduled consults versus signed agreements over the last 90 days.
- [ ] Check inquiry-to-consult show rate. A prospect who inquires and never gets on the calendar is pure wasted spend. Anything below 50 percent means your follow-up process is leaking, not your marketing.
- [ ] Time your speed to first contact. Pull ten recent inquiries and measure minutes from form submission to a human reaching out. If the answer is measured in hours, that’s your cheapest available CAC improvement. Concierge prospects are shopping two or three practices simultaneously.
- [ ] Audit what happens on days 3 through 30 after an inquiry. Most concierge prospects don’t sign on the first touch. They’re evaluating a $3,000 annual commitment. If there’s no email sequence, no second call, no invitation to a practice event, you’re paying to generate interest and then abandoning it.
- [ ] Confirm your CRM actually records enrollment date and source together. Verification: run a report right now that shows members enrolled last month grouped by source. If you can’t produce it in five minutes, fix this before you spend another dollar on ads.
The Panel Cap Rule Most Benchmark Articles Ignore
Most CAC analysis breaks when it’s transplanted from SaaS into concierge medicine. Your growth is capped. A concierge physician holds 300 to 600 members depending on model. Once the panel is full, additional acquisition spend has nowhere to go.
That changes the entire logic of what’s “reasonable.” If you’re at 40 percent panel fill, an above-benchmark CAC is often the right call. Every empty slot is lost revenue that compounds. Paying $1,200 to fill a slot worth $7,800 in lifetime value is a good trade even if the textbook ratio says you overpaid, because the alternative is no member at all.
If you’re at 90 percent fill, the calculus inverts completely. At that point your marketing budget should shift toward retention, waitlist building, and raising prices, not acquisition. I’d argue most concierge practices at high fill rates are overspending on acquisition by a wide margin and underspending on the member experience that determines whether tenure is three years or eight.
Use this as a quick decision matrix:
| Panel fill rate | What CAC target to run | Where the budget should go |
|---|---|---|
| Under 50% | Aggressive. Up to 40-50% of first-year revenue is defensible | Paid search, community events, referral partner development |
| 50-75% | Standard. Target 25-33% of first-year revenue | Balanced acquisition plus conversion rate work |
| 75-90% | Selective. Target under 25%, prioritize high-fit members | Referral channels, reputation, consult conversion |
| Over 90% | Minimal. Waitlist mode | Retention, price increases, adding a provider |
The practices that get this wrong tend to get it wrong in one direction: they underspend when the panel is empty because acquisition cost “feels high,” then keep spending out of habit once they’re full. Both mistakes cost real money.
Checklist Three: Compliance and Claims Checks Before You Scale Spend
Raising your acquisition budget means more people see your advertising, which means more regulatory surface area. Run these before you pour money into a channel.
- [ ] Review every outcome claim in your ads and landing pages. Language implying guaranteed health results, or that membership will produce specific clinical outcomes, is a problem in most states. Verify by having someone outside your marketing team read your top five landing pages and flag anything that sounds like a promise.
- [ ] Confirm your testimonials meet FTC endorsement standards. Real, unpaid or disclosed, representative of typical experience. Patient testimonials about clinical results carry extra scrutiny under state medical board advertising rules.
- [ ] Check your state medical board’s advertising regulations directly. They vary a lot. Some states restrict before/after imagery, some require specific disclaimers, some regulate how you describe board certification. Your attorney or compliance counsel should sign off, not your agency.
- [ ] Verify membership agreement language matches your marketing. If your ads promise 24/7 physician access and your agreement says business hours with an answering service, that gap becomes a complaint. Read them side by side.
- [ ] Make sure you’re not implying insurance replacement. Concierge and DPC practices need to be precise here. Describe what membership includes without suggesting it substitutes for coverage, since that framing draws regulatory attention in several states.
We’re a marketing agency, not your counsel. Every practice should have their own compliance review on advertising claims before scaling, especially when adding a new channel.
Score Yourself: Is Your Acquisition Cost Reasonable?
Count the boxes you could honestly check across all three sections above. Then score the four questions below, since these are the ones that determine whether you have a CAC problem or a different problem wearing a CAC costume.
Question 1: Is your cost per enrolled member under one-third of first-year membership revenue? (Yes = 3 points, within 50% = 1 point, above that = 0)
Question 2: Does CAC pay back within 12 months of enrollment? (Yes = 3, 12-24 months = 1, longer = 0)
Question 3: Is your consult-to-enrollment rate above 50 percent? (Yes = 2, 35-50% = 1, below = 0)
Question 4: Can you attribute at least 70 percent of new members to a specific source? (Yes = 2, 50-70% = 1, below = 0)
8-10 points: Your acquisition economics work. Your constraint is volume, not efficiency. Spend more, and focus energy on whether your panel can absorb it.
5-7 points: You have one broken link, usually conversion or attribution rather than cost. Fix that before increasing budget. Adding spend to a leaky funnel just makes the leak more expensive.
Under 5: Don’t scale yet. You’re either measuring wrong or your funnel is losing people somewhere you can’t see. Both are fixable in 60 to 90 days, and both get worse if you throw money at them first.
And if you scored high on the math but your panel still isn’t filling, the problem is demand, not acquisition cost. Concierge medicine only works in markets with enough households willing and able to pay out of pocket for access. That’s a positioning and market question, and we’ve written separately about how functional and concierge practices build local demand. The short version: if you’re the fourth concierge practice in a market that can support two, no CAC target will save you.
What to Do in the Next 30 Days
Pick the smallest fix with the biggest effect. In our experience with concierge and functional medicine clients, that’s almost always one of three things.
If your speed to lead is over an hour, fix that first. It costs nothing and it’s the single most reliable way to lower cost per enrolled member. Assign one person, set a 15-minute standard, measure it weekly.
If your consult conversion is under 40 percent, the problem is the consult itself. Most concierge meet-and-greets are too clinical and not enough about what daily life with the practice feels like. Rewrite the agenda around access, response time, and what happens at 9pm on a Sunday.
If you genuinely can’t attribute members to sources, spend 30 days building that before touching anything else. You cannot improve a number you can’t see, and every recommendation here depends on it.
Then re-run this checklist in a quarter. CAC moves. A number that was reasonable when your panel was half empty stops being reasonable at 85 percent fill, and the practices that stay profitable are the ones that re-benchmark instead of setting a target once and defending it forever.
Get a Real Number for Your Practice
If you got through this and realized you can’t confidently fill in half the inputs, that’s the most common outcome. It’s also the fastest thing to fix.
Book a free patient acquisition audit and we’ll build your actual cost per enrolled member, map where inquiries are dropping out between first contact and signed agreement, and tell you whether your CAC is reasonable for your panel fill rate. No obligation, no pitch deck, and if your numbers already work we’ll tell you that and send you on your way.
