Dental practice startup costs: the itemized 2026 guide

How much does it cost to open a dental practice in 2026?

This is usually the first question, and many of the answers online are a single number with no math behind it. Here is the math. The table below is the Alithos planning model: the same formula behind the cost estimator on the homepage, run for 3 to 10 operatories in leased space. It is planning math, not a survey of what other offices spent and not a quote. The full method, plus the ground-up columns, is on the 2026 dental office cost benchmark page.

Each range is the model's point estimate plus or minus 5%. "All-in" means build-out, equipment, imaging, cabinetry, IT and furniture, soft costs and $85,000 of working capital. It does not include land, and it does not include the costs covered later in this guide that sit outside a project budget.

How does that compare with what others publish? An ADA News expert column says opening a practice often takes $500,000 at minimum.^[2] That is a floor, not a typical figure, and the model's smallest case sits above it. A 2026 guide from Dental & Medical Counsel, a California dental law firm, puts a typical build-out budget at $300,000 to $600,000 or more for construction, equipment, technology, millwork, MEP, medical gas and permits.^[3] That scope leaves out working capital and most soft costs, so it should land below an all-in number, and it does.

The point of the table is not that your office will cost $933,500. The point is that you can see which lines produce the total and which of them you control. The rest of this guide takes them one at a time. If you are still deciding whether to open at all, start with how to open a dental practice, which puts these costs in order on a timeline.

What are the line items in a dental startup budget?

The model breaks every project into eight lines. The table shows each one for a 5-operatory office in leased space, at standard finish and at premium finish with CBCT. These are the model's point estimates. The published ranges add and subtract 5%.

Two things stand out. First, the build-out family (construction, cabinetry and soft costs) is $518,500 of the $933,500 standard budget, about 56%. Second, the premium column is $302,500 higher, and $125,000 of that is construction finish, $80,000 is equipment and $70,000 is CBCT. Finish level is a choice. So is CBCT. Those are the two biggest levers you hold before a single quote comes in.

Here is what each line covers, with a link to the page that goes deeper.

Space. Square footage sets construction, cabinetry and soft costs all at once, so it is the first number to get right. The model uses 500 sq ft per operatory for 3 to 5 ops, 450 for 6 to 7, and 425 for 8 or more. The operatory square footage calculator and how much space you actually need walk through it.

Construction. The tenant build-out: walls, plumbing to every chair, electrical, HVAC, medical gas, ceilings, flooring and finishes. It is the largest line. See dental office build-out cost.

Equipment. Priced per operatory in the model. It is the line where independent quotes matter most. See dental equipment cost.

Imaging. A fixed package, not a per-op number. Standard is sensors and a panoramic unit. Premium adds CBCT. See whether CBCT belongs in a startup.

Cabinetry. Operatory and sterilization casework, modeled at 10% of construction. It moves with the size of the build-out.

Soft costs. Everything you pay for that is not built or bolted down. Covered below and in the costs nobody bids.

IT and furniture. A base of $45,000 plus $3,000 per operatory for the network, computers, phones, reception and staff furniture.

Working capital. Cash to run the practice before collections catch up. Covered below and in working capital for a dental startup.

How much does the build-out cost?

In the model, construction in leased space runs $170 per square foot at standard finish and $220 at premium. On 2,000 square feet that is $340,000 to $440,000 before cabinetry and soft costs. On 2,500 square feet it is $425,000 to $550,000. Those rates sit inside the dental leasehold range of $150 to $350 per square foot published by Dental & Medical Counsel in 2026, toward the lower half.^[3] If your market, your landlord's shell or your design runs expensive, your rate can land well above the model's.

You will also see a much larger number in national reports. JLL's 2026 benchmark puts the national average all-in fit-out for medical outpatient space at $412 per square foot, starting from a warm white box, with hard costs of $226.^[4] That figure is for medical outpatient space in general, not dental, and "all-in" there includes soft costs, furniture and technology. Do not compare it directly with a dental hard-cost rate. It is useful as a reminder that once everything is counted, the per-square-foot number gets large.

The condition of the suite matters more than any rate. Second-generation space that already has dental or medical plumbing, power and HVAC can cost far less to finish than a cold shell. One contractor estimates the saving on previously medical space at 30% to 50%.^[5] Treat that as one firm's view, not a rule. A tenant improvement allowance from the landlord can also offset part of construction, though it is usually paid back through rent. Use the TI allowance calculator to see what an allowance is worth on your square footage, and read how TI allowances work before you sign a letter of intent.

Construction input prices also move. The U.S. Bureau of Labor Statistics tracks them in its Producer Price Index, which includes indexes for inputs to construction.^[6] A per-square-foot rate from last year is a starting point, not this year's price. For the full breakdown by finish level, see dental office build-out cost and construction cost per square foot.

How much does dental equipment cost per operatory?

The model allows $42,000 per operatory at standard and $58,000 at premium. For a 4-op office that is $168,000 to $232,000, and for a 5-op it is $210,000 to $290,000. Imaging is a separate line: $60,000 for sensors and a pano, or $130,000 for a package with CBCT. The standard figures are consistent with the $100,000 to $200,000 that Dental & Medical Counsel publishes for equipment on a standard build.^[3]

CBCT is the single biggest equipment decision. Vendor-published prices for a new dental CBCT run roughly $40,000 to $150,000, depending on field of view, features and brand.^[7][8] Installation, shielding, software and service plans are usually extra. The model's $130,000 premium imaging package, which includes sensors and a pano, sits inside those ranges. Whether CBCT belongs on day one depends on what you will use it for, and the CBCT decision covers that question on its own.

Equipment prices are negotiable. The practical rule is to get two or three line-item quotes and compare them against one list, item by item, before you sign anything. A single bundled number, especially one attached to a free design, tells you very little. That is the job of an independent quote review: comparing quotes line by line against the budget, without a commission on the outcome. More in dental equipment cost.

Tax rules can change when equipment is deducted, not what you pay for it. For tax years beginning in 2026, the federal Section 179 limit is $2,560,000, reduced dollar for dollar once qualifying purchases exceed $4,090,000, according to IRS Revenue Procedure 2025-32.^[9] California's own limit is much lower: $25,000, phasing out above $200,000 of qualifying purchases, and California does not follow federal bonus depreciation, per the Franchise Tax Board's 2025 instructions.^[10] Other states set their own rules. This is general education, not tax advice. Confirm your situation with your CPA. The Section 179 calculator shows the mechanics.

What do soft costs include?

Soft costs are the fees that come with a project but are not construction or equipment. In a dental startup that usually means architectural design, mechanical, electrical and plumbing engineering, permits and plan-check fees, attorney review of the lease and other contracts, accounting and entity setup, and loan fees charged by the lender. The model sets soft costs at 12% of construction. On a 5-op standard build that is $51,000. On a 5-op premium build it is $66,000.

A percentage is a planning shortcut. In real life, some soft costs behave like fixed fees (an attorney's lease review may cost about the same for 2,000 or 2,800 square feet), and some grow with the size and complexity of the job (design and engineering). Permit fees depend on your city. Loan fees depend on your lender and the loan amount. Ask every professional for a written fee before you engage them, and add each one to the budget as it comes in.

Soft costs are easy to under-budget, because nobody puts them in a single bid. The contractor prices construction. The dealer prices equipment. Nobody prices the permit, the lease review and the loan fee together unless you do. The costs nobody bids lists them.

How much working capital does a dental startup need?

The model sets working capital at $85,000 for every scenario. It is cash, held in reserve, to pay rent, payroll, loan payments, supplies and your own living costs while the schedule fills and insurance payments catch up with the dentistry you have already done. Insurance collections lag production by weeks, so a new office pays its bills for a while before the money from its first patients arrives.

I set this line first, before construction or equipment, for one reason. When a build runs over, working capital is the line that gets quietly cut, because it is the only line nobody is selling you. A beautiful office with no reserve is the riskiest version of the project. Decide the reserve, protect it, and make the other lines fit around it.

The right number for you depends on two things the model cannot know: your monthly overhead and how fast your schedule fills. The useful way to think about it is gross versus net. The gross reserve is months of overhead times your monthly overhead. The net need is the gross reserve minus the collections you realistically expect during those months. The $85,000 model line is a default, not a recommendation for your office. For a lender's view, one dental lender writing in ADA News in 2026 cites a cash reserve at closing often in the $50,000 to $75,000 range, in an acquisition context.^[11] A startup has no existing patient base, so I would not plan on the low end. Work it through in working capital for a dental startup.

What costs are left out of most startup estimates?

A project budget prices the office. It does not price everything you will spend between signing a lease and seeing a full schedule. These are costs that are easy to leave out, and the Alithos model leaves them out too.

None of these is exotic. They are left out because each belongs to a different party, and no single party is responsible for adding them up. Some can be folded into the working-capital reserve. Others, like land, need their own budget. The full list is in the costs nobody bids, and the order in which they hit is in the dental practice startup checklist.

How do costs differ for a lease, a condo and a ground-up build?

The project path changes the construction rate more than anything else. In the model, ground-up construction runs $340 per square foot at standard and $420 at premium, double or nearly double the leased rates. Because cabinetry and soft costs are a percentage of construction, they double too. Equipment, imaging, IT and working capital stay the same, since a chair costs the same in any building.

The model's ground-up rates are on the conservative side of published ranges. Dental & Medical Counsel puts ground-up construction at often $400 or more per square foot.^[3] Your market may run higher than the model, and the model does not include land.

Lease is the lowest capital commitment and usually the fastest route to opening. You fund the finish-out, possibly offset by a TI allowance, and pay rent that builds no equity. Ground-up is the largest commitment: land, site work, shell and finish-out, with the longest timeline. In exchange you own the building. A condo, where you buy your suite in a shared building, sits between the two. You own the suite and skip the land purchase, but you pay association dues and have less control over the building. The model does not price condos, because the purchase price depends entirely on the local market. A condo budget is the suite price plus the finish-out, which behaves much like a leased build-out.

The right path is the one whose monthly cost your practice can carry, not the one with the nicest building. Build, lease or condo covers the three-path comparison, and building a dental office covers the ground-up route in detail. If you are weighing a startup against buying an existing practice, read startup vs. acquisition as well.

How does cost change with the number of operatories?

Total cost rises with every operatory, but cost per operatory falls. In leased space at standard finish, a 3-op office plans at about $212,000 per operatory and a 10-op at about $152,000.

Two things cause the drop. The first is fixed lines. Imaging ($60,000), the IT base ($45,000) and working capital ($85,000) add up to $190,000 whether you build 3 operatories or 10. Spread over 3 chairs that is about $63,000 each. Over 10 it is $19,000.

The second is the core rooms. Every office needs a reception area, a front desk, sterilization, a lab, a mechanical room for the compressor and vacuum, a staff room, restrooms and an office for the doctor. Those rooms do not shrink much when you drop an operatory, so small offices carry more square feet per chair. That is why the model uses 500 sq ft per op for 3 to 5 ops, 450 for 6 to 7 and 425 for 8 or more. You can see the step at 6 ops, where space per op drops from 500 to 450 and cost per op falls by about $16,700.

A lower cost per chair does not mean you should build more chairs. An empty operatory still costs money every month. Size the office to the staff you will actually have in the first few years, plus room to add chairs later. Roughing in plumbing and power for a future operatory during the build is usually simpler than opening walls to add it later.

What monthly loan payment does a startup budget imply?

The Alithos estimator assumes a 15-year loan at 8.25%. At that rate, each $100,000 borrowed costs about $970 a month. The formula is the standard loan payment: amount × r ÷ (1 − (1 + r)⁻¹⁸⁰), where r is 0.0825 ÷ 12. If the full midpoint budget were financed, the payments would look like this.

The 8.25% figure is a planning assumption, not a quote. It sits between the bank prime rate, which was 7.00% in the Federal Reserve's H.15 release of October 30, 2026,^[12] and the SBA's maximum variable rate on a 7(a) loan over $350,000, which is prime plus 3.0%, or about 10.0% at that prime rate.^[13] Your rate depends on your lender, your credit and the market on the day you lock it.

The term matters as much as the rate. Real loans are often split into pieces with different terms. SBA 7(a) loans generally run up to 10 years for equipment and working capital and up to 25 years for real estate.^[14] At 8.25% over 10 years, each $100,000 costs about $1,227 a month instead of $970. A budget financed on shorter terms has a higher payment than the table shows. Try your own amount, rate and term in the dental loan payment calculator.

How do lenders decide whether the budget works?

Lenders care less about the total than about whether the practice can carry the payment. The main test is the debt-service coverage ratio, or DSCR: the cash flow available to pay debt divided by the debt payments. A DSCR of 1.25× means the practice produces $1.25 of cash flow for every $1.00 of loan payments. Many dental lenders look for a DSCR of at least 1.25, and one lender writing in ADA News in 2026 describes that as a guideline, not a strict minimum.^[11][15] Lenders often look at global DSCR, which also counts your personal debt payments and, at many lenders, your living costs.

The last column of the payment table is the cash flow each budget needs to clear 1.25× on the project loan alone. For a 5-op lease standard office that is about $135,800 a year, before your student loans, your mortgage and your own pay. For a sense of scale, the same ADA News column says overhead in a well-run general practice typically runs 58% to 68% of collections, from a lender's view.^[11] The ADA Health Policy Institute reports average gross billings of $965,660 per private-practice general dentist in 2025.^[16] Billings are not collections, and that average covers dentists at every stage of practice, not startups in their first year. Your projection has to be built on your own expected production and payer mix.

Lenders also look at the structure. The SBA 7(a) program allows loans up to $5 million.^[13] Under SBA SOP 50 10 8, effective June 1, 2025, startups need an equity injection of at least 10% of total project cost on SBA loans, according to a law-firm summary of the rule.^[17] Conventional dental lenders set their own terms. Bank of America Practice Solutions, for example, advertises up to 100% project financing for new office startups, covering design, construction, equipment and working capital, subject to credit approval.^[18] Ask each lender for its own thresholds on credit, liquidity and coverage.

The full financing picture is in dental practice financing. Test your own numbers with the DSCR calculator, and read what lenders want to see before your first meeting.

How do you turn ranges into your own number?

A planning range tells you whether a project is in the right neighborhood. Your number comes from replacing each assumption with a fact about your project. This is the order I work in.

1. Set the operatory count from staffing. Start with the doctors and hygienists you will actually have in the first years, then add room to grow. The op count sets square footage, which sets most of the budget.
2. Choose the path. Lease, condo or ground-up. Price at least two if you are unsure, because the gap can be several hundred thousand dollars before land.
3. Price equipment independently. Get line-item quotes, compare them against one list and against the budget, and decide on CBCT on its merits.
4. Set working capital before construction. Decide the reserve from your overhead and ramp, then protect it when other lines run over.
5. Test DSCR with your lender's numbers. Run the payment at a realistic rate and term, and check that projected cash flow clears the coverage your lender looks for, with your living costs included.

You can do the first pass yourself with the cost estimator. If you want a second opinion before you commit, the Feasibility Check is a $2,500 flat-fee go / no-go screen that covers space and site fit, a high-level equipment budget range and a DSCR pre-check against the 1.25× standard. The fee credits toward the Budget Plan. The Budget Plan is a flat fee of $7,500 to $10,000, with the exact fee and scope set in writing before work starts. It builds the line-item budget, the build vs. lease vs. condo projections and the lender-ready package. For owner-side advisory through opening, Project Navigator starts from $20,000, quoted per project. Availability depends on your project's state and is confirmed before engagement.

I am not a contractor, architect, engineer, real estate broker, lender, attorney or CPA. Your attorney reviews the lease and contracts before you sign, and your CPA confirms the tax treatment. My job is the budget: the numbers each of those people works from. You can see every guide in this series on the guides hub, and look up any term in the glossary.
