Dental Practice Overhead: Where the Money Actually Goes

The Number Most Practice Owners Get Wrong

For the planning case used here, overhead is 55% of collections: 55 cents of each collected dollar goes to the included operating expenses before owner compensation. The 50-65% comparison range and 59% solo versus 52% group examples are retained planning inputs, not verified current ADA percentiles. Practice type, owner compensation, depreciation and the denominator can change the comparison.

What is dental practice overhead? Dental overhead is the defined operating-expense total divided by collections for the same period. In this planning model, overhead is 55% and staff costs are 25-28% of collections. Hygiene contribution, lab spend and monthly ledger review are useful tests, rather than proven traits of a measured below-50% cohort. See how dental practices compare to other healthcare specialties.

Knowing collections alone does not establish contribution. Reconcile the included expenses before using the overhead ratio to make a staffing or purchasing decision.

The Full Expense Breakdown

The following category ranges are planning comparisons. They are not a verified current survey table, and their endpoints should not be added as though each came from the same practice. Start with your ledger and define what each category includes.

Staff Costs: The Biggest Line Item

Staff is the largest modeled expense. The 25-28% loaded-cost range and $152K per employee are planning comparisons, not verified current Overjet cohort estimates. Below $130K per employee is a prompt to check scheduled hours, provider mix, collections and full-time-equivalent definitions. It does not prove overstaffing.

Before adding a hygienist, compare available appointments, demand and complete incremental cost. An 85% scheduled-utilization threshold can be tested as a planning rule, but it is not a universal hiring boundary. Track collected contribution per hygiene hour and the appointments that additional capacity could actually serve.

The table's 25-28% staff line is fully loaded, including benefits. A hypothetical 25% wages-only figure plus 5% benefits would be 30% loaded, above that comparison range. Do not add benefits twice; retain wages and benefits separately within the same total.

Lab Fees: The Margin You're Sending Out the Door

Lab fees at 8-10% are the second-largest variable cost. This line item can vary widely between practices; the ranges here are planning inputs. A practice that sends all crown work to a premium domestic lab might run 12%. One using offshore labs or chairside milling might run 5%.

Fictional comparison: at a $1,200 crown fee, lab costs of $150 versus $350 differ by $200 per unit. On 300 crowns, that is $60,000 of direct lab-cost difference before remakes, shipping, chair time, collections and overhead. It is not a supplier quote or a guaranteed profit gain.

But quality matters. Remakes cost more than the lab fee savings. Track your remake rate by lab and factor that into the true cost per unit.

Facility: The Fixed Cost Trap

Use 6-8% of collections as a facility-cost planning comparison. A result above 8% can reflect rent, low collections, unused capacity or other included costs; it does not identify the cause. A result below 5% does not establish a patient-volume constraint.

If facility cost remains above your defined comparison range, compare lease alternatives, usable capacity and realistic collections before renewing or expanding. A two-year duration alone does not establish that the space is wrong.

Include compressed air systems, vacuum maintenance, nitrous plumbing and water treatment. A $5K-$15K annual allowance can be used in a fictional sensitivity, but use actual service contracts and repair history for the budget.

Supplies: Death by a Thousand Purchases

Dental supplies at 5-7% sounds small until you realize that's $50K-70K on a practice with $1M annual collections. The problem is fragmentation. A fictional 4-6-supplier purchasing setup illustrates why invoice-level and procedure-level comparisons can help; it is not a measured practice count.

The fix is boring but effective: quarterly supply audits, consolidating vendors for volume pricing, and tracking cost per procedure rather than total spend. A 1-point reduction in supply costs on $1.5M collections is $15,000.

Technology: Where Capex Hides as Overhead

The 3-5% technology planning line includes subscriptions, imaging and equipment leases in the table. State whether depreciation is included in your overhead ratio. Cash purchases, debt principal, lease payments and depreciation are different views; do not count the same equipment cost twice.

The Equipment Trap

This deserves its own section because it's where the most money gets destroyed.

For purchase planning, test scanner prices of $80K-$150K, digital impression systems at $30K-$50K and chairside milling at $150K-$180K as illustrative sensitivities, not current vendor quotes. Those low and high endpoints total $260K-$380K before installation, training or finance cost. Obtain an actual quote for the intended equipment.

Fictional annual-cost model: a $100,000 scanner used for five years contributes $20,000 of annual capital cost. Add $5,000 service, $5,000 financing cost and $10,000 staff and operating cost: $40,000 annually. At 400 scans, the modeled cost is $100 per scan; at 100 scans, it is $400. These are assumptions, not quoted patient prices, referral prices or measured utilization. Do not include loan principal again if capital cost is already included in this economic comparison.

The utilization test for every equipment purchase: Define the incremental benefit per scan from net collections or a referral cost you actually pay and would avoid. Count that benefit once. For example, $40,000 annual modeled cost divided by an assumed $150 incremental benefit requires about 267 scans annually, before any omitted costs. This is a fictional break-even sensitivity, not a universal 60% or 8-12-scans-per-week rule. Compare current eligible volume and an evidence-backed demand forecast.

Compare ownership, leasing and referral arrangements using the same eligible volume and cost definitions. An equipment model can identify a break-even volume; it cannot establish the outcome for every practice.

What Separates 40% Overhead Practices from 60% Overhead Practices

The fictional 40% and 60% endpoints differ by 20 percentage points. The five tests below help diagnose your own records; they are not a measured comparison of the best and worst practices.

1. Hygiene department profitability. Fictional sensitivity: on $1.5M of collected revenue, assume hygiene accounts for 34% ($510K) with complete direct costs and a 47.5% margin, yielding $242,250 contribution. At the same collected revenue and 30% margin, it yields $153,000. The difference is $89,250 before overhead and tax, under these stated assumptions. These assumptions are not a measured practice comparison; production and cash collections must be tracked separately.

2. Production per hour. Test $475-$575 and $700 as planning sensitivities, not verified current ADA average or top-quartile values. Retain procedure mix and available chair hours alongside scheduled production. An unused hour is not automatically $500 of lost collections, and capacity alone does not establish unmet demand.

3. Collection rate. In a fictional same-cohort comparison, 95% versus 98% collections on $1.5M of production differs by $45,000. Define gross production, contractual adjustments, net collectible amount and the observation window before using that ratio. Review actual adjustments and receipts; the difference does not prove a write-off or front-desk cause.

4. Staffing ratios. Test 1.5-2.0 and 2.5 staff per provider as planning sensitivities, with hygienists included consistently as providers. Full-time equivalents, opening hours and procedure mix matter. A staffing ratio does not establish a 58% overhead outcome.

5. Monthly financial reviews. A monthly ledger review provides more frequent opportunities to investigate expense changes than a quarterly review. The actual detection time depends on record completeness, the close and who acts on the findings; a 30-day detection result is not guaranteed.

The Benchmarks That Matter

If you track nothing else, track these four numbers monthly:

A 60% overhead case leaves 40% of collections before items excluded from your overhead definition. Whether that covers owner compensation, debt service and reinvestment depends on the actual dollar amounts and classifications.

Level's healthcare benchmark page presents source-attributed references and planning inputs. It is not a measured Level dental cohort. Compare those definitions with your practice's actual expense classifications.

FAQ

Q: What is a good overhead percentage for a dental practice?

A: There is no universal good percentage without a consistent expense definition. Use the 55% model and 50-65% sensitivities to ask questions, not as measured current percentiles. Compare practice mix, owner compensation, depreciation and collections before diagnosing a category or setting a target.

Q: How do I reduce dental practice overhead without cutting quality?

A: Review staff utilization, lab costs including remakes and supply costs per procedure. Estimate any savings from your own invoices, schedules and eligible alternatives. A 3-5-point reduction is a scenario to test, not a typical result or a promise that quality is unchanged.

Q: Should I invest in a CBCT scanner or digital impression system?

A: Get a current equipment quote, total annual ownership cost and the incremental benefit for an eligible procedure. Then calculate break-even volume. In the fictional model above, $40,000 annual cost divided by $150 benefit is about 267 scans a year. Actual referral economics, demand, financing and clinical suitability can produce a different decision; a weekly scan count alone does not establish payback.

Q: Is a fractional CFO worth it for a dental practice?

A: If your overhead is above 58%, or you can't identify your per-provider production numbers, a review can help identify the actual cost, provider-production or revenue-cycle gap. Results depend on supported practice records; Level does not publish a typical savings figure or first-quarter payback guarantee. See how Level works for healthcare practices.
