Outpatient Clinic Break-Even: About $63K Monthly Revenue
An outpatient clinic needs about $63,100 in monthly break-even revenue in the Year 1 base case Here’s the quick math: $52,383 fixed monthly costs divided by an 83% contribution margin equals $63,112 At the forecast $74,750 monthly revenue, the clinic has about $11,638 of monthly revenue cushion before operating losses The model reaches break-even in Month 2, but minimum cash still falls to $208,000 in Month 12, so cash planning still matters

Which outpatient clinic expenses are fixed, and which move with patient volume?
Cost classification
Break-even gets reliable when rent, software, and insurance stay fixed while supplies, lab inputs, referrals, and marketing move with revenue. Misclassifying payroll or lab spend can make Month 2 break-even look safer than it is.

Break-Even Treatment
Common Mistake
Clinic Lease Payment
Fixed
Use $15,000 per month across the relevant planning range.
Tying rent to visits instead of capacity.
EHR & Scheduling Software Licenses
Fixed
Use $1,200 per month unless license terms change.
Spreading it per patient as if fully variable.
Professional Liability Insurance
Fixed
Use $3,000 per month in monthly overhead.
Dropping it from break-even because it is not clinical labor.
Administrative Wages
Semi-fixed
Start with $27,083 per month in the first year, then step up as FTE hiring changes by year.
Treating all payroll as fixed forever.
Medical Supplies Consumed
Variable
Model as a revenue-linked percentage, from 6.0% in the first year to 5.0% in Year 5.
Using one flat dollar amount despite higher patient volume.
Laboratory & Diagnostic Reagents
Variable
Model as revenue-linked usage, from 4.0% in the first year to 3.5% in Year 5.
Treating all lab spend as fixed overhead.
External Lab Services & Referrals
Variable
Use the referral-linked rate, from 3.0% in the first year to 2.5% in Year 5.
Ignoring outside lab leakage in contribution margin.
Patient Acquisition Marketing
Variable
Model as revenue-linked spend, from 4.0% in the first year to 3.0% in Year 5.
Calling all marketing fixed when demand still needs paid acquisition.
How does break-even shift from lean launch to full clinic scale?
Scenario table
Lean launch is close to break-even because Year 1 revenue only slightly clears fixed overhead. By Year 3 and Year 5, higher capacity use and more clinical roles spread the lease and staff base across much more revenue, so the cushion grows fast.
Planning case only; results will move with volume, staffing, and payer mix.

What breaks first if visits run light or costs run hot?
Stress test
Year 1 clears break-even by only $11,638 a month, so the cushion is thin. Stay above about 560 billable encounters, because a small demand miss, early payroll, or higher supply and lab costs can erase that margin fast.

What should the founder verify before signing the lease and locking the clinic build-out?
Founder checklist
Do not lock the lease or build-out until Year 1 volume, staffing, and launch timing all fit the $63,112 monthly break-even revenue target. If any one slips, the fixed-cost load can outrun the opening clinic base fast.
1Capital Load$815K + $15K/mo
Verify the $815,000 build-out, equipment, furnishings, IT, EHR, security, and lab spend still leaves the $15,000 lease inside the break-even plan.
2Demand Proof660/mo
Check that Year 1 demand really supports 660 monthly treatments across the five service lines, because mature-year demand does not pay opening rent.
3Billing ReadyPre-acq
Finish payer credentialing and the billing workflow before paid acquisition starts, or the clinic can burn cash on visits that do not convert cleanly to revenue.
4Unit Margin83% CM
Verify each visit keeps about 83% after medical supplies, lab reagents, external lab referrals, and patient acquisition marketing, so volume can cover payroll and rent.
5Staffing Ramp65% cap
Confirm 2 primary care physicians, 1 diagnostic technician, 1 specialist physician, 1 minor procedure nurse, and 2 medical assistants can cover the 65% capacity plan before adding more FTEs.
6Cash Buffer$208K M12
Keep cash above the $208,000 minimum in Month 12 and delay extra FTEs if visits lag, because that is where the model’s cash trough lands.
