Dental Practice Overhead: What the Percentage Really Tells You

Overhead is total operating expense divided by collections, expressed as a percentage. Operating expense includes staff compensation, lab fees, supplies, rent or mortgage interest, equipment, marketing, insurance and utilities, and the denominator should be collections, the cash the practice actually keeps, rather than production, the amount billed.

The production-to-collections distinction matters because adjustments and uncollected balances sit between the two. A practice that tracks overhead against production can look healthier than it is. The Pagac Dental Financial Funnel follows the flow from production through adjustments, collections, variable costs, fixed overhead, compensation strategy and taxable income, and the overhead percentage belongs in the middle of that flow, measured against collections.

ADA Health Policy Institute survey data has commonly placed typical general practice overhead near 61 to 62 percent of collections, with staff compensation the largest single overhead category, often reported around 25 to 30 percent of collections. Specialty practices, location and practice structure all move the number, so there is no universal correct percentage.

The more useful comparison is the practice against itself: what was overhead last year, what is it this year, and what changed. A practice running at 58 percent that is drifting toward 66 percent has a problem even if both numbers look reasonable, and a practice at 65 percent that is investing in a new associate or a second location may be making a deliberate trade. The trend and the reason behind it matter more than the single number.

Staff compensation is usually the largest category, so scheduling, overtime, benefit structure and whether each provider is producing enough to support their cost deserve the closest look. Lab fees and supplies track production volume and should be reviewed against fee schedules and vendor pricing. Facility cost, rent or ownership, is fixed and should be tested against the square footage the practice actually needs.

Marketing is the category where spending often runs ahead of measurement. The question is not just what the practice spends, but what it costs to acquire a new patient and whether the mix of procedures and payers is improving. Each category should be reviewed as part of the monthly financial package, not once a year at tax time.

Use overhead as a starting point for decisions, not a report card. A rising percentage may signal falling production, rising costs or both, and the fix is different in each case: more production from existing capacity, a fee schedule review, a payer mix change or a cost reduction. The analysis should separate what the owner controls from what is driven by the market.

Because the number depends on the practice's own facts, specialty, location and structure, an owner should review it with an advisor who understands dental practice economics rather than comparing to a generic benchmark. The goal is not to hit a target percentage; it is to understand the practice's cost structure well enough to make better decisions about staffing, scheduling, fees and growth.
