Medical practice payroll reserve: when visits are not cash
Build a medical practice payroll reserve from completed visits, realized fees, fixed staffing and collection delays in a two-clinician outpatient scenario.
Published by StartFigures · Editorial standards · Correction guidance
The StartFigures two-clinician medical-practice case needs about 24 completed visits per day to cover operating costs, but it still budgets $450,000 of opening operating cash. That reserve carries the initial appointment ramp, payroll before collections arrive, and an additional buffer. A break-even month does not mean that the clinic has recovered its opening investment or collected all the fees it earned.
The case is a physician-led outpatient primary-care office with four exam rooms, one paid physician owner, one nurse practitioner, two medical assistants, a manager/billing lead and a receptionist. It serves a mixed patient panel through primary care, chronic-condition follow-ups and preventive visits. It excludes a hospital, surgery center, subscription practice and any assumed specialist expansion.
The financial figures below are an authored U.S. planning scenario in constant 2026 dollars. They are business calculations, not clinical guidance, a national clinic average or a representation of a purchased product's example returns. The complete Medical Practice case holds the same opening budget and operating inputs.
Protect the paid calendar before selling appointments
The two clinicians each budget 32 patient-facing hours and eight nonvisit hours per week. The latter covers results, documentation, messages, referrals and other duties; owner-management demands also need to fit the paid schedule. The appointment model cannot spend those hours twice.
The mature case completes 14 visits per clinician per average operating day. Across five days, that gives 140 completed visits per week, or 606.2 per month under the site's 4.33-week convention. A planning ceiling of 18 visits per clinician per day gives 779.4 monthly slots. The mature case therefore uses 77.8% of that practical capacity.
| Resource | Capacity and use | Revenue role |
|---|---|---|
| Physician owner | 18 daily slots; 14 completed visits | $185 realized fee per visit |
| Nurse practitioner | 18 daily slots; 14 completed visits | $155 realized fee per visit |
| Two medical assistants | Paid rooming and support coverage | No separate encounter revenue |
| Four exam rooms | Two rooms per clinician for workflow | No room-based revenue multiplier |
At the planning ceiling, 32 patient-facing hours spread over 90 weekly slots imply about 21.3 minutes per slot. The mature 70 completed visits per clinician leave more room for longer encounters and ordinary scheduling gaps. Actual appointment lengths must reflect the patient and service mix; neither number is a treatment-duration recommendation. Holidays, staff leave and cancellations need a dated calendar, with the relief allowance and utilization adjusted to avoid assuming a fully staffed year that cannot be delivered.
Medical assistants perform important clinical and administrative support work. That does not mean each rooming or specimen task creates an independently billable visit. The BLS medical-assistant profile describes this support role. This model assigns one encounter to one clinician revenue stream and keeps support labor in payroll.
Replace the fee schedule with a collectible-fee estimate
The model uses a $170 blended realized fee: equal visit counts at $185 for physician encounters and $155 for NP encounters. These are authored amounts after expected contractual reductions and noncollection. They are not posted list charges, coding advice or guaranteed payer allowances.
One observed pricing reference shows why the distinction matters. HonorHealth's published self-pay schedule lists $132.86 for an established-patient moderate-complexity prompt-pay visit and $188.53 for a high-complexity one. New-patient moderate and high prompt-pay prices are $173.65 and $231.74. Those are one Arizona provider's published terms, accessed October 2, 2026; they do not establish an insured practice's average receipt. HonorHealth primary-care pricing.
Medicare also does not provide one universal fee for a primary-care visit. Its Physician Fee Schedule uses service-level relative values, geographic adjustments and conversion factors. The actual services, setting and practitioner status matter. A commercial contract or a different patient mix can produce a different result. CMS 2026 Physician Fee Schedule final rule.
For each important visit type, document the applicable allowed amount, expected patient responsibility, adjustments, noncollection and receipt timing. Obtain actual participation dates and fee schedules; an enrollment application is not a confirmed contract. AAFP's credentialing policy supports access to the fee schedule after credentialing, but that policy does not guarantee this clinic's enrollment. AAFP third-party credentialing.
Pay the owner before calculating surplus
The annual base payroll is $744,000. It includes $250,000 for the physician owner, $140,000 for the NP, $48,000 each for two medical assistants, $64,000 for the manager/billing lead and $45,000 for the receptionist. The resulting $595,000 wage base receives a selected 20% employer-cost allowance and $30,000 for paid relief.
Those are staffing assumptions. For context, BLS reports May 2025 national medians of $244,180 for family-medicine physicians, $132,300 for nurse practitioners and $45,690 for medical assistants. The local recruiting market, benefits, paid leave, employer taxes and replacement coverage still need quotes and a complete employment budget. BLS physicians, BLS nurse practitioners, BLS medical assistants.
Fixed overhead adds $180,000 annually, including rent, utilities, insurance, software, outreach, professional support and upkeep. Payroll and overhead therefore total $77,000 monthly. Another 12% of earned revenue is allocated to clinical consumables, routine in-scope test costs and variable billing/payment expense.
The simplified operating threshold is $77,000 divided by an 88% contribution margin, or $87,500 of monthly earned revenue. At $170 per completed visit and 21.65 average operating days per month, that is 23.77 daily visits, rounded up to 24. The mature 28-visit case earns $103,054 monthly and produces $13,687.52 of operating surplus before depreciation, interest and income tax.
| Case | Fee / daily visits | Operating result |
|---|---|---|
| Base | $170 / 28 | $13,688 |
| Lower fee | $150 / 28 | $3,018 |
| Fewer visits | $170 / 24 | $732 |
| Combined downside | $150 / 24 | -$8,413 |
These cases keep the 12% variable share and $77,000 fixed cost unchanged; they do not assign probabilities. A different service mix may also change costs. The combined downside illustrates why a reasonable-looking fee and a nearly full paid roster can coexist with a monthly loss. Use the break-even calculator for a sensitivity, then rebuild staffing and capacity if the operating format changes.
Fund the ramp and the receivables separately
The opening scenario starts at 40% of mature visits and adds six percentage points per month until it reaches maturity. Payroll and fixed overhead run throughout. The shared calculation reaches monthly operating break-even in month nine, but the cumulative operating deficit peaks near $173,445 at the end of month eight. Year one still ends with about $135,018 of operating loss.
The clinic also has to wait for earned fees to turn into cash. For a transparent planning stress, this case adds a receivables exposure equal to 45 days of mature earned revenue: $103,054 multiplied by 1.5 months, or $154,581. This is an authored allowance, not a measured days-sales-outstanding ratio. Adding it to the peak operating deficit is a conservative reserve bridge, not a dated simulation of every claim and payment.
| Cash purpose | Amount | Basis |
|---|---|---|
| Peak ramp deficit | $173,445 | Shared monthly operating ramp |
| Collection-delay allowance | $154,581 | 45 days of mature earned revenue |
| Remaining buffer | $121,974 | Reserve less both allocations |
| Total reserve | $450,000 | Authored opening cash allocation |
The remaining buffer is not automatically available for distribution. Denied claims, delayed participation, larger patient balances, taxes, debt payments or more expensive clinical cover can consume it. Replace the allowance with a monthly schedule of claims, expected collections, patient payments, payroll dates, accounts payable and financing before treating the reserve as sufficient.
A useful weekly control separates completed encounters, earned net revenue, submitted claims, cash receipts and overdue balances. A rising appointment count with rising receivables can increase the payroll funding requirement even while the income statement improves.
Keep clinical setup from spending the cash buffer
The total opening allocation is $850,000: $400,000 for clinical setup, deposits, preopening work and contingency, plus the $450,000 operating reserve. The broader $620,000–$1,150,000 range represents different fitted-premises and reserve scopes; it is not a statistical range of U.S. startups.
Equipment alone does not explain the project cost. As a concrete anchor, Booth Medical lists a UMF FusionONE+ powered exam table at $5,971.42, with a shipping quote required. Four listed units total $23,885.68 before freight, tax and options. The $75,000 equipment allowance also covers other exam-room furniture, basic diagnostic and limited testing equipment, delivery and setup; those remaining amounts are authored and need itemized bids. A product listing does not determine whether a proposed room or equipment selection meets its actual accessibility requirements. Booth Medical exam tables.
Specify the test menu before buying equipment. CMS distinguishes facilities performing human-specimen testing from collection-only facilities, with certification requirements tied to the work performed. Do not buy a laboratory scope by implication from a floor plan. CMS getting started with CLIA.

Make the lease decision with one joined operating plan
Before committing, put four pieces together: a paid clinician and support calendar; a service-level fee and payer-participation register; coordinated site and equipment bids; and a monthly cash schedule. If the lower-fee, lower-attendance case cannot be funded, resolve the scope or funding problem before the fixed obligations begin.
The four exam rooms support this delivery plan; they do not multiply the two clinicians into four billable resources. The NP's permitted role and any collaboration or supervision requirements need state-specific verification. AANP state practice environment.
The Medical Practice evidence register explains each input's source boundary. The business plan organizes the clinic's operating decisions, while the financial model provides editable capacity and financial schedules. Their source examples require adaptation to actual services, staff, contracts and funding; neither a template nor an operating surplus establishes a clinical approval or a financing outcome.
