Startup budgets, buildout, credentialing, and working capital: what a launch really costs, and where physicians most often miscalculate.
Key Takeaways
- Plan on $70,000–$100,000 as the floor for a lean launch and $500,000 or more for equipment-heavy specialties.
- Space and buildout are the largest controllable costs, so negotiate them before you commit to anything else.
- Start payer credentialing at least 120 days before opening or plan to see patients you cannot bill for.
- Working capital covering six months of operating expenses belongs in the startup budget, not in a footnote.
Ask five advisors about the cost to start a medical practice and you will get five different numbers. Most are defensible, and none of them will match your situation exactly, because the real answer depends on specialty, market, and how much planning happens before the lease gets signed. What follows are the ranges that hold up under scrutiny, the line items that blow up budgets, and the two costs that almost never make it into the spreadsheet.
What It Actually Costs to Start a Medical Practice
Wolters Kluwer’s practice-formation guidance puts the typical cost of starting a medical practice at $70,000 to $100,000, with staffing, office space, and EHR and equipment as the key drivers. That figure describes a lean launch. DoctorsManagement, a practice-management advisory firm, publishes a wider and more realistic band for 2026: roughly $70,000 for a spare solo primary care launch, climbing past $500,000 for specialty practices that need imaging or procedure rooms.
The spread is the point. A solo internist subleasing space with a cloud EHR and two staff members lives at the bottom of the range. An orthopedic or gastroenterology startup with a procedure suite lives at the top. Before you price anything, decide which practice you are building, because every downstream number follows from that choice.
The Line Items That Blow Up Budgets
Three categories account for most of the variance between the plan and the final invoice.
- Space and buildout. Per DoctorsManagement’s 2026 startup guidance, typical practices need 1,500 to 3,000 square feet at $2,000 to $8,000 per month, and buildout or renovation can run $50,000 to $250,000. Buildout is where first-time owners get hurt: change orders, code requirements for exam-room plumbing, and lead-lined walls for imaging all land after the budget is set. Negotiate a tenant-improvement allowance before signing, not after.
- Equipment. Initial general equipment purchases alone typically require $10,000 to $15,000 before any specialty-specific equipment, per DoctorsManagement. Phase what you can. A practice does not need every instrument on day one; it needs the ones that generate revenue in month one.
- Recurring operating costs. Telecom, EHR licensing, medical waste, janitorial, and software subscriptions run $1,000 to $3,000 per month before payroll. These are small individually and relentless collectively.
- Staffing. Wolters Kluwer names staffing among the largest cost drivers of any launch, and the timing is what stings: your first hires start weeks before the first patient arrives, for training, systems setup, and scheduling. Budget at least two months of full payroll before opening day, and resist the urge to overstaff for the volume you hope to have in year two rather than the volume you will have in month two.
The launch budgets that fail are rarely wrong about the rent. They are wrong about the six months after the doors open.
Credentialing Is the Silent Budget Killer
No line item destroys more launch plans than payer enrollment. Credentialing commonly takes 90 to 120 days per payer, with full ranges of 60 to 180 days depending on payer and state, according to analysis by Neolytix, a revenue-cycle services firm. The same analysis pegs the cost of an uncredentialed provider at roughly $1,000 to $5,000 per day in unbillable or delayed revenue, and that money is largely unrecoverable because payers rarely grant retroactive effective dates.
The planning rule, echoed in NGA Healthcare’s payer-by-payer credentialing guidance, is to start credentialing at least 120 days before your opening date. Medicare, Medicaid, and each commercial payer run on separate clocks, so file everything in parallel the moment you have an entity, an NPI, and an address. An opening day with a full schedule and no participating contracts is a bad week that lasts a quarter.
Working Capital Is a Startup Cost
Here is the number nobody budgets: the cash required to operate before collections catch up. Even with clean claims and completed credentialing, the first payer checks arrive weeks after the first visits, and the patient panel takes months to fill. Rent, payroll, malpractice premiums, and those $1,000 to $3,000 in monthly recurring costs are all due on schedule regardless.
Treat six months of operating expenses as part of the startup number, financed alongside the buildout and equipment. Lenders respect a launch plan that names this figure explicitly. Owners who skip it end up funding payroll from personal savings in month four, which is a poor position from which to make any decision.
From the Field
A solo internist in the Southeast came to Guidestone eight months before her planned launch with a lease shortlist and no budget. We built the full launch model, capped the buildout at $85,000 by negotiating a tenant-improvement allowance, phased $40,000 of equipment into the second year, and filed credentialing with all seven target payers 140 days before opening. The practice opened on schedule with every major contract effective on day one, total launch spend of $162,000 against a $175,000 plan, and enough working capital to reach break-even in month nine without a bridge loan.
Work Backward From Opening Day
Sequence beats spending. A launch that runs in the right order costs meaningfully less than the same launch run in the wrong order. Twelve months out: form the entity, secure financing, and lock the full budget including working capital. Nine months out: sign the lease and start buildout with penalties for contractor delays. At least 120 days out: file every credentialing application. Ninety days out: hire and train core staff, stand up the EHR, and test the billing workflow with dummy claims. Sixty days out: open scheduling and begin community outreach so the first month’s template is not empty.
Every reversal of that order costs money. A lease signed before financing weakens your negotiating position. Staff hired before the EHR is configured means paying people to wait. Credentialing filed after opening converts your best early patients into charity care.
On financing itself: lenders compete for physician startup loans, which means you can and should shop the terms. Bring a complete package to at least three banks, including the full budget, the working-capital reserve, and a monthly cash-flow projection through break-even. The projection matters more than the collateral. A lender who sees that you understand the revenue lag will price the loan better, and the exercise of building the projection will surface every weak assumption in your plan while corrections are still free.
Your First Launch Does Not Have to Look Like One
Most physicians start one practice in a career. The learning curve is steep, the tuition is real money, and every mistake in this article is one someone paid to discover. That is the case for borrowing experience instead of buying it: an operator who has sequenced multiple launches will spot the missing line item, the soft lease term, and the credentialing gap while they are still cheap to fix. The startup budget is the one document where a second set of executive eyes pays for itself before the doors open.
