What This Calculator Does
This dental overhead percentage calculator analyzes your practice expenses across all major cost categories and compares them to 2026 dental industry benchmarks. It breaks overhead into staff costs (benchmark: 25% to 30% of collections), supplies and lab fees (benchmark: 6% to 8%), facility costs (benchmark: 4% to 7%), and other operating expenses. The tool calculates your total overhead percentage, net income, and identifies the annual savings potential if overhead is reduced to the 60% benchmark target. The 2026 national average for dental practice overhead is 60% to 65% of collections, with top-performing practices maintaining overhead below 55%.
The Formula
Total operating expenses include all costs of running the practice before the dentist owner takes compensation. This includes staff salaries, benefits, dental supplies, lab fees, rent, utilities, insurance, marketing, technology, and miscellaneous expenses. The overhead percentage represents how many cents of every collected dollar go toward running the business. The remaining percentage is available for doctor compensation and profit.
Step-by-Step Example
Enter monthly collections
Your practice collects $85,000 per month after adjustments and write-offs.
Enter staff costs
Salaries: $20,000. Benefits and taxes: $4,500. Total staff: $24,500 (28.8% of collections).
Enter supplies, lab, and facility costs
Supplies: $3,200. Lab fees: $2,800. Rent: $4,500. Utilities: $900. Insurance: $700. Total: $12,100.
Review overhead analysis
Total overhead: $41,100 (48.4%). Net income: $43,900 (51.6%). This is well below the 60% benchmark, indicating strong cost management.
Real-World Use Cases
Practice Purchase Due Diligence
Evaluate a practice acquisition by analyzing its overhead structure. Practices with overhead above 65% may have hidden inefficiencies or inflated costs that affect valuation.
Annual Budget Planning
Use the category breakdown to set spending targets for each expense area and identify categories that exceed benchmarks.
Cost Reduction Initiatives
Identify the largest overhead categories and benchmark them against industry standards to prioritize cost reduction efforts where they will have the greatest impact.
Common Mistakes to Avoid
Including doctor compensation in overhead calculations. Overhead represents all expenses except the owner dentist pay. Associate dentist compensation, however, is included in staff costs.
Using production instead of collections as the denominator. Overhead should be measured against collected revenue, not billed production, since write-offs and uncollected fees do not generate cash.
Ignoring seasonal variations. Some expenses like marketing, CE courses, or equipment purchases create monthly spikes. Use 3-month or 12-month rolling averages for accurate benchmarking.
Not separating fixed and variable costs. Understanding which costs scale with production (supplies, lab fees) versus those that remain constant (rent, insurance) is critical for growth planning.
Cutting lab fees at the expense of quality. Switching to the cheapest lab can increase remakes and patient dissatisfaction, ultimately costing more than the savings.
