Introduction
Most dentists know their gross production number. Far fewer know what percentage of it disappears into overhead before they see a dollar of profit. The ADA Health Policy Institute reports that dental practice overhead averages between 59% and 65% of gross collections, with high performers managing overhead at 55% or below. Every percentage point matters. A practice collecting $900,000 per year at 62% overhead nets $342,000. Bring overhead to 57% and that same revenue produces $387,000, a $45,000 difference without a single additional patient. This calculator takes your total expenses by category (staffing, lab, supplies, facility, marketing, and other fixed costs) and divides them by your gross collections to return your overhead percentage, broken down by cost center so you can identify where the leaks are.
What This Calculator Does
This calculator takes your expense inputs across major dental practice cost categories and your gross collections for the same period, then returns your total overhead percentage and the percentage contribution of each cost category. It supports monthly, quarterly, or annual analysis. The output tells you which expense categories are within benchmark ranges and which are running above norms, giving you a specific target for cost reduction rather than a vague instruction to "cut expenses."
The Formula
Total expenses include all practice operating costs: staff wages and payroll taxes, dental supplies, lab fees, facility costs (rent, utilities, maintenance), marketing, equipment leases, insurance, and administrative costs. Gross collections is the actual cash received, not production. Dividing total expenses by gross collections and multiplying by 100 gives the overhead percentage. Track each expense category as a percentage of collections to benchmark against industry norms.
Step-by-Step Example
Gather your expense data by category
Pull your P&L for the period from your accounting software (QuickBooks, Xero). Separate expenses into: staff costs (wages + payroll taxes + benefits), dental supplies, lab fees, facility (rent + utilities), marketing, and other (software, CE, professional fees). Example monthly figures: staff $28,000, supplies $4,500, lab $5,200, facility $6,800, marketing $2,100, other $1,800 = total $48,400.
Enter your gross collections for the same period
Gross collections is actual cash received in the period, from insurance payments and patient payments. Example: $82,000 collected in the month.
Calculate overhead percentage
Total overhead = $48,400 / $82,000 = 59.0%. This is within the typical industry range but above the high-performer target of 55%. The calculator returns both total overhead and each category as a percentage of collections.
Compare each category to benchmarks
Staff: $28,000 / $82,000 = 34.1% (benchmark: 24-30%, flagged as high). Lab: $5,200 / $82,000 = 6.3% (benchmark: 7-12%, within range). Supplies: $4,500 / $82,000 = 5.5% (benchmark: 5-7%, within range). Staff cost is the priority reduction target.
Real-World Use Cases
Pre-Purchase Due Diligence on an Acquisition
A dentist evaluating a practice for purchase receives three years of P&L statements. Running the overhead calculator on each year reveals that staff costs have climbed from 27% to 36% of collections over three years, while production has been flat. This signals overstaffing or wage creep and becomes a negotiation point in the purchase price and a day-one operational priority if the deal closes.
Benchmarking After Adding an Associate
Six months after hiring an associate, the owner runs the overhead calculator to assess impact. Lab fees jumped from 8% to 11% because the associate prefers an external lab for all crowns. The calculator quantifies the lab cost increase at $2,400 per month and prompts a conversation about in-house milling or in-network lab relationships.
Planning a Fee Schedule Increase
A practice at 61% overhead wants to improve net income without cutting staff. The calculator shows that a 7% fee increase on services not covered by insurance would add approximately $3,200 monthly to collections. At current expense levels, that drops overhead to 58.1%, adding nearly $38,000 to annual net income.
Comparison
| Expense Category | Industry Low | Benchmark Target | High (Action Needed) |
|---|---|---|---|
| Staff (wages + payroll taxes) | 22% | 24% - 30% | >33% |
| Dental Supplies | 4% | 5% - 7% | >8% |
| Lab Fees | 6% | 7% - 12% | >13% |
| Facility (rent + utilities) | 4% | 5% - 8% | >10% |
| Marketing | 1% | 2% - 5% | >6% |
| Total Overhead | 50% | 55% - 62% | >65% |
Common Mistakes to Avoid
Using gross production instead of gross collections as the denominator. Production includes services billed but not yet collected. Collections is actual cash received. Using production inflates the denominator and makes overhead appear lower than it actually is, masking a cash flow problem.
Excluding the doctor's own salary or owner draw from the overhead calculation. If the owning dentist produces and does not include their compensation in expenses, overhead appears artificially low. For accurate benchmarking, include a market-rate doctor compensation as an expense line even if the owner takes it as a draw.
Analyzing overhead annually without monthly tracking. Annual figures smooth over seasonal spikes. A month with high lab costs from a big cosmetic case or a month with two staff members on leave will distort annual averages and obscure the actual pattern. Monthly tracking catches trends early.

Accuracy and Disclaimer
This calculator provides overhead percentage estimates based on the expense and collections inputs you provide. Results are for internal practice management analysis and do not constitute financial, tax, or business advice. Overhead benchmarks vary by specialty, region, practice size, and market conditions. Consult a dental-specific CPA or practice management consultant for financial planning and strategic decisions.
Conclusion
Overhead management is where practice profitability is won or lost. A 5% overhead reduction in a $1 million practice adds $50,000 in net income without a single additional procedure. Once you know your overhead rate and which categories are over benchmark, use the Dental Production Per Hour Calculator to see whether a production increase or an expense reduction is the faster path to your profit target, and run the Dental Insurance Write-Off Calculator to quantify how insurance adjustments are affecting your net collections baseline.
