Concierge Medicine Financial Model: How Profitability and Cash Flow Change as You Grow Your Patient Panel

A concierge practice with 200 members at $350/month generates $840,000 in annual revenue and shows $253,000 in net income. Profitable by any measure. But after estimated taxes and a modest startup loan, only $153,000 stays in the bank. The P&L and the bank account are telling two different stories — and most physicians planning a transition never see the second one.

Key Takeaway: Every concierge practice has two break-even points — one for the P&L (134 members at $350/month) and one for cash flow (143 members). The 9-member gap between them is where taxes and debt consume your profit. Understanding both numbers before you sign a lease is the difference between a successful transition and a cash crisis in Year 1. Try the interactive simulator →

We built a Concierge Medicine Financial Simulator that lets you model this yourself. Adjust membership fees, patient volume, physician salary, and startup loan — and watch both your P&L waterfall and cash flow waterfall update in real time.

This article walks through the model, explains the assumptions, and shows you exactly where the money goes at every stage of growth.

The Two Numbers Every Concierge Physician Needs Before Signing a Lease

Most concierge practice startup guides give you one number: how many patients you need to cover your overhead. That is your P&L break-even. It is necessary. It is not sufficient.

The number that actually determines whether you can make payroll, pay your quarterly estimates, and service your startup loan is the cash flow break-even — and it is always higher than the P&L break-even.

Here is why. Your P&L measures revenue minus expenses. It tells you whether the practice earned more than it spent. But it does not account for:

• Estimated quarterly taxes (roughly 30% of net income for an S-Corp physician)
• Startup loan payments (principal + interest on the $100K-$175K you invested to launch)
• Working capital needs (cash tied up between when you pay staff and when memberships clear)

At a $350/month membership fee with South Florida operating costs, the math works out to:

The 9-member gap between P&L and cash flow break-even does not sound dramatic. But each member at $350/month is $4,200/year. That gap represents $37,800 in annual revenue that your income statement says is profit — but your bank account never sees.

This is the same profit-cash disconnect we find in imaging centers, law firms, and marine service businesses. The mechanism is identical. Only the inputs change.

What a Concierge Practice P&L Actually Looks Like (South Florida, 2026)

We modeled a standard concierge practice in the Broward County / Palm Beach corridor — the area the American Academy of Private Physicians (AAPP) identifies as one of the highest concentrations of concierge physicians in the country, anchored by MDVIP's founding in Boca Raton.

Fixed Monthly Operating Costs: $19,750

These are not national averages. They reflect actual costs in premium South Florida medical office markets where concierge practices cluster — zip codes where a standard commercial medical lease runs $28-$42 per square foot.

Variable Costs: $33 per Member per Month

Every patient on your panel adds incremental cost:

• Medical supplies: $8/member (POC testing supplies, exam consumables)
• Lab / diagnostics: $12/member (in-house basic labs, send-out coordination)
• Patient portal / communications: $3/member (EHR per-patient licensing)
• Payment processing: 2.9% + $0.30/transaction (standard merchant processing)

At $350/month, the variable cost per member is approximately $33.45. That gives you a contribution margin of $316.55 per member — meaning each new patient after break-even contributes $316 per month directly to the bottom line.

This is the operating leverage that makes concierge medicine financially attractive. Once you clear your fixed costs, the marginal economics are extraordinary — nearly 90% of each additional membership dollar flows to income.

The Cash Flow Gap: Why 134 Members Breaks Even on the P&L but Not in the Bank

Here is the cash flow waterfall at 200 members, $350/month:

Monthly P&L:

The P&L says you are making $21,133 per month — $253,596 per year. Solidly profitable.

But the cash flow waterfall adds three more lines:

Your bank account grows by $12,793 per month — not $21,133. The $8,340 difference vanishes into taxes and debt service. These obligations are real. They hit your checking account every month. But they never appear on the income statement.

This is precisely the pattern we document in every cash flow analysis we run. One imaging center we analyzed showed 702 claims to break even on the P&L but 922 claims to break even on cash flow. Different industry, identical mechanics.

Try it yourself: Open the Concierge Medicine Financial Simulator and slide the member count from 134 to 143. Watch the cash flow waterfall go from red to green. That 9-member window is where most physicians get surprised in Year 1.

Four Practice Models, Four Financial Realities

The financial picture changes dramatically based on your fee structure and panel size. Here is how four common models compare at their typical operating points:

Assumes $250K physician salary, $2K/month startup loan, 30% estimated tax rate, South Florida costs.

Three things jump out:

DPC is cash flow negative at 400 members. The $175/month fee generates strong volume but thin margins. At $146.63 contribution margin per member, you need 288 members just to break even on the P&L — and the model does not become cash flow positive until roughly 310 members. This is viable, but the runway is longer. Read our full comparison of concierge vs. insurance-based models for the trade-offs.

Standard Concierge is the sweet spot for most South Florida physicians. At 250 members and $350/month, you clear both break-even thresholds with comfortable margin. Total physician compensation of $576K compares favorably to the $200K-$400K range in traditional practice.

Premium and Executive models reach profitability faster with fewer patients. A premium practice at $650/month breaks even on cash flow at just 75 members. The trade-off is a smaller addressable market — fewer patients can pay $7,800/year — but in affluent South Florida markets (Weston, Boca Raton, Coral Gables, Key Biscayne), the demand exists.

Try It Yourself: The Interactive Concierge Medicine Financial Simulator

We built the Concierge Medicine Financial Simulator to put this analysis in your hands.

What you can model:

• Patient panel: Slide from 0 to 600 members and watch both the P&L and cash flow waterfalls rebuild in real time
• Fee structure: Choose from DPC ($175), Standard ($350), Premium ($650), Executive ($1,000), or enter any custom fee
• Three views: See every number in absolute dollars, as a percentage of revenue, or per member — the same three lenses we use in our fractional CFO engagements
• Advanced controls: Adjust physician salary ($100K-$500K) and startup loan payment ($0-$5K/month) to match your situation

What you will see:

1. A growth curve showing how net income and net cash flow change with each new member — with break-even points clearly marked
2. A P&L waterfall breaking down exactly where your revenue goes: facilities, staff, compliance, marketing, accounting, supplies, and physician salary
3. A cash flow waterfall showing what happens after taxes and debt — the part most financial projections leave out
4. Dynamic insight callouts that warn you when you are in the profit-cash disconnect zone

The model uses South Florida cost assumptions (Broward/Palm Beach/Miami-Dade) and current 2026 benchmarks. The assumptions are fully transparent — expand the "Model Assumptions" section to see every line item and its source.

What the Model Can't Tell You (And What an Accountant Should)

The simulator uses industry benchmarks. It is accurate for planning. But your practice is not a benchmark — and several decisions will materially change these numbers:

Entity structure matters. An S-Corp election with properly set reasonable compensation can save a concierge physician $15,000-$31,000 per year in self-employment taxes. The model assumes S-Corp structure. If you are operating as a sole proprietorship or single-member LLC, your tax line will be significantly higher.

Lease terms vary wildly. A $4,500/month lease in Weston is very different from a $2,800/month lease in Coral Springs — and a physician converting an existing practice may already have favorable lease terms. One physician we spoke with negotiated a 6-month rent abatement during their transition period, which shifted their break-even timeline by 40 members.

Deferred revenue creates complexity. Annual memberships paid upfront create a cash-vs-accrual timing issue that affects both your taxes and your cash position. If 30% of your panel pays annually in January, you have a cash surplus in Q1 and a deferred revenue liability that complicates your tax picture for the rest of the year.

Your actual numbers are in QuickBooks. The simulator shows you what to expect. A Benefique fractional CFO engagement pulls your actual data — your lease, your staffing costs, your collections timing, your tax situation — and builds a model that is not a simulator but a forecast. The kind of analysis that traditional consulting charges $15,000-$35,000 to produce once, we update monthly from your live QBO data.

If you are within 12 months of launching or transitioning to concierge medicine, reach out for a consultation. We will run your actual numbers through the same framework and show you both break-even points — the one on the income statement and the one in the bank.

FAQ — Concierge Medicine Financial Model

How many patients do I need to break even in a concierge practice?

At a $350/month membership fee with South Florida operating costs ($19,750/month fixed), you need approximately 134 members to break even on the P&L and 143 members to break even on cash flow. These numbers change based on your fee, location, and physician salary. Use the Concierge Medicine Financial Simulator to model your specific scenario.

What is the difference between P&L break-even and cash flow break-even?

P&L break-even is when revenue covers all operating expenses and physician salary — the point where net income turns positive. Cash flow break-even adds estimated taxes and debt service. A practice can be profitable on the income statement while the bank account is still shrinking. This is the profit-cash disconnect we document in our cash flow waterfall analysis.

How much does a concierge physician make in South Florida?

Total physician compensation in a South Florida concierge practice ranges from $430,000 to over $1,000,000 depending on fee structure and panel size. At the standard model (250 members, $350/month), total compensation including salary and profit distributions is approximately $576,000 per year. See our full income analysis for detailed scenarios by practice model.

What are realistic operating costs for a concierge practice in 2026?

Our model uses $19,750/month in fixed operating costs for a South Florida concierge practice, including $4,500 for office lease, $8,200 for staff (MA + front desk + benefits), $3,000 for outsourced accounting/tax/CFO services, and $2,100 for technology and marketing. Variable costs add approximately $33 per member per month. See our startup cost breakdown for the full line-item analysis.

Should I choose DPC or traditional concierge?

DPC ($150-$200/month) requires a larger patient panel (288+ members) to break even because the contribution margin per member is lower. Traditional concierge ($350-$650/month) breaks even faster with fewer patients but targets a smaller market. In affluent South Florida markets, standard concierge at $350/month is the most common model. Our financial comparison tool lets you model both scenarios side by side.

What is the contribution margin in concierge medicine?

At $350/month, the contribution margin is approximately $317 per member per month — meaning 90% of each additional membership dollar flows to the bottom line after variable costs. This operating leverage is what makes concierge medicine financially attractive: once you clear your fixed costs, growth is extremely profitable. However, cash flow break-even requires clearing an additional threshold that accounts for taxes and debt.
