Dental Practice Overhead Calculator

A typical dental practice overhead breakdown splits into four main categories. Staff and payroll is the largest, usually 25–35% of collections, covering all salaries, benefits, and payroll taxes. Facility and occupancy — rent, utilities, and phone — accounts for 5–10%. Clinical costs including dental supplies and lab fees make up 12–18%. Business and admin expenses such as marketing, software, and malpractice insurance round out the remaining 5–10%. Together, a well-run practice keeps total overhead at or below 65% of gross collections.

The average dental practice overhead percentage in the US sits between 60–70% of gross collections, with the industry benchmark target being 55–65%. General dentistry practices tend to land around 62–65%, while specialty practices like orthodontics often run lower (50–58%) due to fewer supply and lab costs. Practices with high lab-intensive restorative work can see overhead climb to 70%+. If your overhead exceeds 75%, it signals a profitability problem that needs immediate attention.

Healthy dental practice overhead percentages break down as follows: staff costs should sit between 25–35% of collections (anything above 38% is a red flag), facility costs at 5–10%, clinical supplies and lab fees combined at 12–18%, and business and admin costs at 5–10%. Your net profit margin — what you keep after all expenses including your own compensation — should be 25–35%. Use these benchmarks alongside the calculator above to identify which specific category is pulling your overhead above the target range.

To reduce dental practice overhead, start with your largest cost category — staffing. Audit your team-to-revenue ratio and ensure hygienists and chairs are fully scheduled before adding headcount. For lab fees, renegotiate contracts with your lab or bring simple cases in-house. For supplies, join a group purchasing organization (GPO) to access volume pricing. On the revenue side, improving case acceptance rate and reducing no-shows increases your top line, which automatically lowers your overhead percentage even if expenses stay flat. A 5% improvement in case acceptance can move overhead by 3–4 percentage points without cutting a single cost.

The ideal dental practice overhead percentage is between 55–60% of gross collections, leaving a net profit margin of 40–45% before owner compensation. Most advisors consider anything under 65% healthy and sustainable. Practices consistently running below 55% typically have strong case acceptance, low staff turnover, efficient scheduling, and in-house lab capabilities. While achieving sub-55% overhead is possible, chasing it by cutting staff or marketing below sustainable levels can backfire — the goal is profitable growth, not just expense reduction.
