Labour cost is the largest expense category for most healthcare practices. It includes clinical staff, administrative staff, and in many cases the practice owner's effective compensation. The percentage of revenue consumed by labour determines a great deal about practice profitability, scalability, and resilience.
This post covers benchmark ranges for labour cost as a percentage of revenue across major healthcare specialties, what drives variation, and what to do when your number falls outside typical patterns.
What's Included in Labour Cost
The basic calculation is straightforward but worth being precise about scope.
Total labour cost typically includes wages and salaries paid to all staff, payroll taxes (employer portion), benefits (health insurance, retirement contributions, paid time off), and any contractor or temporary staff costs. For practices with associates compensated on percentage structures, the associate's compensation is included. For owner-operated practices, the owner's normalized compensation (what an associate would earn for similar clinical work) is typically included for benchmarking purposes — though some practices exclude owner compensation when calculating labour cost ratios for internal management purposes.
Total labour cost as a percentage of revenue is then total labour cost divided by total practice revenue over the same period.
The treatment of owner compensation is the most consequential calculation choice. Including owner compensation produces a higher labour cost percentage that's directly comparable to corporate-owned or DSO-style practices where the equivalent clinical work is done by employed practitioners. Excluding owner compensation produces a lower percentage that reflects only non-owner staffing costs but isn't comparable across different ownership structures.
Benchmark Ranges by Specialty
Published practice management sources describe labour cost ranges that vary considerably by specialty. The numbers below include normalized owner compensation and represent total clinical and administrative labour cost as a percentage of revenue.
General dental practice. Total labour cost commonly falls in the 50 to 60 percent range for solo general dental practices. Wages and benefits for hygienists, dental assistants, and front office staff typically run 25 to 35 percent of revenue. The clinical practitioner component (owner normalized to associate compensation) typically runs 25 to 30 percent. Practices with multiple associates show different distributions but similar aggregate ranges.
Dental specialty practices. Specialty practices often show slightly lower labour percentages than general practice because revenue per visit is higher. Total labour cost commonly runs 45 to 55 percent for endodontic, oral surgery, and orthodontic practices.
Physiotherapy and rehabilitation. Total labour cost commonly runs 50 to 65 percent for physiotherapy practices, with significant variation based on whether the practice uses physiotherapy assistants and how clinical care is structured. Practices with higher assistant ratios typically show lower per-visit labour cost.
Mental health practices. Mental health practices often have the lowest support staff requirements per provider. When normalized owner compensation is included, total labour cost commonly runs 60 to 75 percent of revenue, reflecting that the practitioner's compensation represents most of the cost. Practices that don't normalize owner compensation appear to have much lower labour costs but are operating with the implicit assumption that owner take-home equals practice profit, which understates actual labour economics.
Optometry practices. Total labour cost commonly runs 35 to 50 percent for optometry practices. Optical retail revenue typically dilutes the labour percentage relative to a clinical-only practice because the optical revenue contributes to the denominator without proportional labour cost.
Audiology practices. Similar to optometry, audiology practices with significant hearing aid sales show diluted labour percentages because the hearing aid revenue contributes to the denominator. Total labour cost commonly runs 35 to 50 percent.
General medical practice. Total labour cost varies considerably by country and practice model. Canadian fee-for-service primary care typically runs 50 to 65 percent total labour cost. US practices vary based on insurance contracting and ancillary services. Some specialties show higher percentages reflecting more support staff requirements.
Medical aesthetic and IV therapy. These practices typically show lower labour cost percentages because revenue per visit is high relative to staffing requirements. Total labour cost commonly runs 30 to 45 percent.
What Drives Variation
Two practices in the same specialty can show meaningfully different labour cost percentages. Several factors typically explain the variation.
Staff utilization. Practices with high clinician utilization (full schedules, minimal idle time) typically show lower labour cost percentages because the same labour cost spreads across more revenue. Practices with significant idle clinical capacity show elevated labour percentages.
Support staff ratios. Practices using more clinical assistants and support staff typically have higher labour costs but may produce more revenue per clinician hour, sometimes producing similar percentage outcomes through different cost structures.
Compensation levels. Practices in higher-cost markets pay higher wages, contributing to higher labour costs. The revenue per visit may be correspondingly higher, but the labour percentage often runs above lower-cost markets even with higher revenue.
Benefits structure. Practices providing comprehensive benefits (health insurance, retirement contributions, generous paid time off) carry higher total labour costs than practices offering minimum benefits packages.
Clinical practice model. Premium service models with longer appointments and more thorough patient interactions typically have higher labour cost percentages because the same staffing produces lower volume. Volume-focused models show different patterns.
Owner involvement in operations. Owners who actively manage operations and reduce administrative labour requirements through their own time can show lower formal labour costs but are absorbing the labour cost personally through reduced clinical time or extended working hours.
Reading Your Own Number
The benchmark ranges are most useful as a calibration tool against your specific practice.
If your number is meaningfully above benchmark. Worth investigating. Common causes include over-staffing relative to current volume, below-target clinician utilization, premium compensation packages without offsetting revenue capture, or revenue underperformance making fixed labour costs appear large as a percentage. Each cause has a different remediation path.
If your number is at the low end of benchmark. Often a sign of efficient operations but worth checking that the practice isn't under-staffed in ways that create operational fragility. Practices running at minimum staffing levels can be vulnerable to single-employee absences, turnover, or growth that the staffing model can't absorb.
If your number is significantly below benchmark. Verify the calculation methodology. Sometimes very low numbers reflect excluded categories (owner compensation not included, contractor costs not captured) rather than genuinely low labour cost. Adjusting the calculation to match how the benchmark is typically calculated produces a comparable number.
The Specific Levers
Practices working to optimize labour cost typically have several specific levers available.
Clinical scheduling efficiency. Reducing gaps in clinician schedules, balancing scheduling templates against actual demand patterns, and adjusting appointment lengths to match true clinical time required — these produce direct labour cost improvement without changing staffing.
Cross-training staff. Staff who can perform multiple roles (front desk who can assist clinically, clinical staff who can support administration) reduce the total number of staff required for full operational coverage.
Right-sizing for current volume. Matching staffing to actual current volume rather than aspirational future volume. Practices that staff for 90 percent capacity but operate at 70 percent capacity carry excess labour cost.
Compensation structure review. Periodic review of compensation against market and practice economics. Some practices have compensation that drifted upward over years without corresponding productivity changes. Adjusting through attrition or formal review can reduce excess cost.
Process improvement. Operational improvements that reduce time required for routine tasks — documentation efficiency, billing process automation, scheduling system optimization — can reduce required administrative labour without affecting clinical capacity.
Volume growth. Often the most effective labour cost optimization is growing revenue while holding labour cost relatively flat. The percentage improves through revenue growth rather than cost reduction. This typically produces better staff and patient outcomes than cost reduction approaches.
Where Cost Cutting Goes Wrong
Several patterns commonly produce worse outcomes when practices try to reduce labour costs.
Cutting clinical support staff. Reducing dental assistants, hygiene support, or clinical assistance often slows clinician productivity more than the labour savings recover. The clinician produces less revenue with less support, sometimes producing worse total economics than the original staffing.
Reducing front desk capacity. Front desk staffing affects patient experience, scheduling efficiency, and revenue capture. Cuts here often show up later as patient acquisition and retention issues.
Compensation cuts that drive turnover. Reducing staff compensation below market often produces departures of best staff first. Replacement costs (recruiting, training, lost productivity during transition) often exceed the savings.
Premature outsourcing. Outsourcing functions like billing, marketing, or administrative work can reduce nominal labour cost but introduces other complications. Outsourcing should be evaluated on total cost and operational fit, not just labour cost reduction.
The Real Insight
Labour cost as a percentage of revenue is most useful as a diagnostic metric rather than as a target to optimize directly. A practice running materially above benchmark labour cost has something to investigate — staffing levels, productivity, revenue capture, or operational efficiency. The investigation typically surfaces the actual issue, which may or may not be addressed primarily through labour cost actions.
Practices that successfully manage labour cost typically focus on operational efficiency, productivity, and revenue capture rather than on staff compensation reduction. Sustainable labour cost ratios reflect well-functioning operations more than they reflect aggressive cost management.
The Profitability Calculator models how operating expenses interact with revenue across different capacity levels. Inputting your monthly operating expenses (which include labour cost as the largest component) shows how the practice's profitability scales as revenue grows. The Performance Benchmarks tool lets you compare practice metrics including margin and revenue patterns against published reference ranges.
