What Does It Cost to Open a Dental Practice?

This is an editorial worked case, not a client outcome, market average, lender quote or recommended budget. The opening amounts and cash assumptions match the example in the Dental Second Location Decision Kit. The detailed allocation within each category below is illustrative. Published sources support the planning method and specific operational considerations, not these dollar amounts.

First practice, second location and acquisition are different budgets

A first-time owner still needs premises, equipment, a team and a collections ramp, but has no established office to support early deficits. Personal living costs and any income given up also need a separate cash plan. Do not import the first-site contribution used in this expansion example into a first-practice forecast.

An established owner may reuse administrative systems and management experience, but opening another office can reduce the original office's collections or require replacement clinical coverage. Here, that site's monthly cash contribution falls from $25,000 to $17,000 once the new office opens. An acquisition is different again: an operating practice has a purchase price, transition risks and existing collections to diligence. Use the practice acquisition guide rather than substituting an acquisition asking price for this startup worksheet.

The itemized $500,000 opening allocation

For a real budget, attach a quote, payment date, payer and confirmed funding source to every line. Identify deposits and contingency separately from expenses: they consume or tie up funding, but are not all accounting expenses. The table assumes a leased site, not a real-estate purchase.

The construction contract includes rough-ins, specified casework, data cabling and contractor final connections. Equipment pricing must exclude those same connections; otherwise installation is counted twice. The construction-cost guide reconciles this $240,000 allocation to normalized contractor bids and compares it with a shell-site alternative.

The $15,000 contingency is allocated within the $500,000, not extra free operating cash. For the simplified forecast, the entire opening allocation is treated as spent or unavailable at month zero. Actual unspent contingency can be tracked separately until released. This case omits a property purchase, acquisition price, later capital spending, taxes and lender fees beyond any amounts entered in launch costs; add applicable costs rather than assuming the example covers them.

Reconcile sources, remaining project cash and retained cash

Opening gap = opening uses − available opening sources. Here it is $500,000 − $600,000 = −$100,000: no unfunded opening allocation, with $100,000 left. That says nothing by itself about whether the later cash low is acceptable. Confirm entity, loan and other restrictions before assuming retained first-office cash is available to support a second entity.

What the monthly runway must pay for

Runway is the cash consumed while receipts trail obligations, not an arbitrary percentage of construction. Use cash collections received rather than scheduled production. This case uses the following explicit assumptions:

• Loan: an assumed $500,000 fixed-rate loan at 9% over 120 months; fully amortizing payment approximately $6,333.79 each month, starting in month 1. This is a modeling input, not an offered or published market rate.
• Before opening: the existing office contributes $25,000 per month before owner draw; the new site incurs $10,000 monthly carrying costs and receives no collections.
• After opening: the existing office contributes $17,000 per month before draw, reflecting a net $8,000 coverage/collections reduction. That net change already includes the assumed coverage effect; do not subtract an associate cost again.
• New-office operations: $45,000 monthly fixed cash costs once open, including assumed recurring staffing and occupancy, plus variable costs equal to 25% of collections. The $45,000 replaces, rather than adds to, the $10,000 pre-opening carrying cost.
• Owner draw: $15,000 per month across the combined business from month 1, not $15,000 from each office.
• Base opening/ramp: open in month 4. Collections rise linearly over six open months: $14,166.67, $28,333.33, $42,500, $56,666.67, $70,833.33 and $85,000; then remain $85,000 per month.
• Downside: open in month 6 and collect 20% less at every ramp stage, reaching $68,000 in month 11. The first site continues its $25,000 contribution until that later opening, then falls to $17,000.

Monthly change in combined cash = first-site contribution + new-site collections − variable costs − fixed or carrying costs − debt payment − owner draw. Starting cash is last month's ending cash. For base month 4, the change is $17,000 + $14,166.67 × 75% − $45,000 − $6,333.79 − $15,000 = approximately −$38,708.79. Small differences from adding displayed monthly figures come from rounding; results below use unrounded payments and ramp values.

Before opening, the business consumes approximately $6,333.79 monthly: $25,000 − $10,000 − $6,333.79 − $15,000. After opening, the larger fixed-cost base arrives before mature collections. This is why dividing remaining cash by rent or payroll alone overstates runway.

Base and downside: where the cash actually bottoms

Both scenarios stay above the chosen floor under these assumptions. The downside has only $29,162.11 of room for an unmodeled overrun, extra delay or weaker existing office. It is not enough to note that the account never reaches zero. Decide in advance whether that margin is acceptable and which commitments can change before the protected floor is breached.

Compare the expansion with keeping one office

Without the project, the hypothetical owner retains the original $280,000 and adds 12 × ($25,000 monthly contribution − $15,000 draw) = $120,000, ending at $400,000. That is $168,630.46 above the expansion base ending balance. In this example the loan exactly offsets the opening allocation, so both choices start with the same combined cash: the difference is the first-year cash-generation gap after new debt service, not a second subtraction of the opening budget. It is not accounting loss, return on investment or a cash-payback period; assets and remaining debt also differ.

At mature base collections, the combined business generates approximately $17,000 + $85,000 × 75% − $45,000 − $6,333.79 = $29,416.21 per month before draw, versus $25,000 from staying one-site. A future $4,416.21 monthly improvement does not erase the first-year cash commitment. The profitability guide develops the incremental economics and collection thresholds; the cost answer here stands without using a calculator.

Build a funding schedule, not just a loan request

Attach dates to deposits, progress invoices, equipment payments, recruiting and payroll starts. Then date the actual lender advances and landlord reimbursements. The monthly model above assumes full funding and all opening allocations at month zero; it does not administer staged construction draws. A reimbursement after completion cannot pay an earlier contractor deposit. The separate construction timing example shows a fully funded allocation with a temporary $99,000 gap.

Compare sources by permitted use, net proceeds, payment start and release conditions. SBA's 7(a) overview lists working capital and equipment among program uses; 504 focuses on qualifying fixed assets and excludes working capital and inventory. Neither establishes eligibility for a particular expense or borrower. Keep equipment-only financing and its debt payment alongside the remaining opening costs rather than treating it as financing for the whole project.

Staffing needs dates too. Separate the $20,000 one-time hiring/training allocation from recurring payroll in fixed costs. ADA Health Policy Institute's April 2026 discussion reports continued hygienist hiring difficulty; it supports checking local candidate availability, not a universal payroll percentage. An operatory plan is not a staffed schedule.

For the operating cash portion, build a dated reserve calculation rather than adding a blanket percentage. For the equipment portion, compare shared systems and per-room purchases before assuming every planned room must be fully equipped at opening. Neither schedule should repeat a cost already included here.

Turn the budget into a decision

Before committing, replace assumptions with site/vendor evidence, verify the first office's cash after replacement coverage and confirm that any cash transfer is permitted. Run later opening and weaker collections together; name the cash-floor trigger at which you phase equipment, renegotiate a milestone, reduce a discretionary draw or defer the project. Do not count an unapproved future credit increase as available funding.

The expansion business plan brings the evidence, operator responsibilities and decision gates together. The ungated Dental Second Location Decision Kit lets you replace the worked case with your inputs and inspect its simplified 12-month cash schedule. For borrowing proposals, use the loan-rate and quote-comparison guide.

Sources and methodology

The SBA startup-cost resource supports separating startup expenses and planning funding and break-even; the program sources support use-of-funds distinctions, and ADA supports the staffing discussion. None is evidence that a dental office should cost $500,000. All case amounts, detailed allocations, opening dates and collections are editorial assumptions; the cash results use the shared planner example. The forecast has no staged draws, tax calculation, balloon payment, later capital spending or independent entity-level liquidity test.
