Medical practice overhead: Benchmarks and how to keep costs under control

You added a third provider last year. Revenue grew 28%. But your take-home barely moved. The new provider brought patients, but she also brought a medical assistant, higher supply costs, a renegotiated office lease for additional exam rooms, and an EHR license upgrade. Revenue increased by $320,000. Expenses increased by $295,000. Your practice grew by 28%, and your profit grew by $25,000.

This is the overhead trap that catches growing medical practices. Revenue growth masks expense growth until the practice owner looks at the margin and realizes the business is working harder but not earning proportionally more. The problem is not the growth itself. It is that overhead scaled faster than revenue because nobody was tracking it at the category level as the practice expanded.

Medical practice overhead is every operating expense excluding provider compensation. Controlling it does not mean cutting indiscriminately. It means understanding what each cost category should look like as a percentage of collections and identifying the categories where your practice is spending more than it should.

The overhead benchmarks every medical practice should know

The following ranges, consistent with MGMA practice benchmark data, apply to most primary care and multi-specialty practices with annual collections of $1 million to $5 million.

Total overhead target: 55% to 65% of net collections. This leaves 35% to 45% for provider compensation and practice profit. Practices above 65% are either in early growth phases where revenue has not caught up to infrastructure investment, or they have expense categories that exceed benchmarks.

Support staff compensation: 20% to 25%. This is typically the largest overhead category. It includes medical assistants, front desk, billing, office management, and any other non-provider employees. Payroll taxes and benefits are included. A practice at 28% staff cost is carrying either too many staff for its patient volume or staff whose compensation exceeds market rates.

Rent and facility: 5% to 8%. Lease payments, utilities, property taxes, maintenance, and common area charges. Medical office space commands premium rates due to buildout requirements, but the benchmark still holds. Above 8%, evaluate whether your space utilization justifies the square footage or whether you are paying for rooms that sit empty.

Medical supplies and clinical costs: 4% to 6%. Exam room supplies, clinical disposables, medications administered in-office, and small equipment. This excludes major capital equipment. Practices with in-house labs or imaging services charge higher rates, which is expected if those services generate proportional revenue.

Billing and collections: 4% to 7%. Whether handled internally or outsourced, the cost of submitting claims, posting payments, working denials, and collecting patient balances. Internal billing teams (staff, software, clearinghouse fees) and outsourced billing (typically 5% to 8% of collections) should be compared on a total-cost basis.

Technology and EHR: 2% to 4%. Practice management software, EHR licensing, IT support, cybersecurity, telehealth platforms, and hardware. This category has grown steadily as practices adopt more digital tools.

Insurance: 2% to 3%. Malpractice (often allocated to provider compensation), general liability, property, workers' compensation, and cyber liability.

Marketing: 1% to 3%. Patient acquisition costs include website, SEO, online reputation management, and community engagement.

All other: 2% to 4%. Professional services (legal, accounting, consulting), continuing education, licenses, memberships, and miscellaneous.

Medical practice overhead benchmarks at a glance

The three overhead categories that derail medical practices most often

Not all overhead categories carry equal risk. Three categories account for most of the variance between practices with healthy overhead and those with bloated cost structures.

Staff costs that outpace patient volume growth. A practice seeing 80 patients per day with 12 support staff is running a different efficiency ratio than one seeing 60 patients per day with the same 12 staff. The metric that matters is patient visits per FTE of support staff. For most primary care practices, 12 to 16 patient visits per support staff FTE per day is a reasonable target. Below that ratio, the practice is carrying excess labor capacity.

Calculate this quarterly. When you add staff, verify that patient volume has increased or is projected to increase proportionally. A medical assistant added to support a new provider should be justified by the provider's ramp-up schedule and expected patient volume, not by a general sense that the office feels busy.

Billing costs that exceed collection improvement. Whether internal or outsourced, billing costs should be justified by the collection rate they generate. An internal team costing $180,000 that maintains 94% collection may be outperformed by an outsourced service at $120,000 achieving 96%. On $2 million in expected reimbursement, that 2% difference is $40,000 in additional revenue at a lower cost. Track your accounts receivable aging by payer to verify that collections are arriving on schedule, not just that claims are being submitted.

Review billing cost relative to collection rate annually. If billing exceeds 7% with collection below 95%, the function is both expensive and underperforming.

Technology spending that does not improve efficiency. Practices accumulate tools: scheduling, patient communication, reputation management, telehealth, and intake. When these tools do not integrate or staff bypass them, the practice is paying for technology that adds cost without reducing labor.

Audit your technology stack annually. For each tool, ask: Does this measurably reduce staff time, improve collections, or enhance patient experience? If not, cancel it.

How to build an overhead monitoring system

Overhead control is not a one-time project. It is a monthly discipline that takes 30 minutes and prevents the slow creep that erodes margins over the years. For practices that want to build this monitoring capability without adding internal headcount, the guide to outsourcing finance and accounting covers how outsourced CFO and accounting services create the real-time overhead visibility this approach depends on.

Track overhead by category monthly. Your accounting system should produce a monthly profit and loss statement with enough category detail to calculate each overhead component as a percentage of collections. If your chart of accounts lumps "supplies" into one line that combines clinical supplies, office supplies, and cleaning products, break it apart. The granularity is where the insight lives.

Compare each category to the benchmark quarterly. Pull three months of data and compare each overhead percentage to the benchmarks above. Flag any category more than two percentage points above the top of its benchmark range. That is where the investigation starts.

Calculate overhead per provider. Total overhead divided by the number of providers reveals the infrastructure cost each provider must cover before generating profit. If overhead per provider is $280,000 and a provider collects $380,000, the margin per provider is $100,000 minus the provider's compensation. If the overhead per provider is $350,000, that same provider barely breaks even.

Review staffing ratios when adding providers. Not every new provider needs a dedicated medical assistant, front desk person, and billing specialist. Evaluate which existing staff can absorb additional work before adding headcount. A practice adding a fourth provider might need one additional MA, but can likely share front desk and billing resources across all four.

Overhead discipline is what separates growing practices from struggling ones

The medical and healthcare practices that grow profitably are not the ones with the highest revenue. They are the ones where overhead scales at 60% to 70% of the rate that revenue scales. When collections grow 25%, overhead should grow 15% to 18%, not 25%.

That gap between revenue growth and expense growth is where practice profit accumulates. It does not happen automatically. It happens because someone is watching the numbers monthly, challenging every expense against its benchmark, and asking whether each dollar of overhead is producing a return.

Frequently asked questions

What is a healthy overhead percentage for a medical practice?

A healthy overhead range for most primary care and multi-specialty practices is 55% to 65% of net collections. This leaves 35% to 45% for provider compensation and profit. Practices above 65% have at least one expense category operating above its benchmark. The most common culprit is staff costs, which should sit between 20% and 25% of collections. Above 28%, the practice is either overstaffed relative to patient volume or paying above-market compensation without a productivity justification.

What is the difference between gross and net collections in overhead calculation?

Overhead should always be calculated as a percentage of net collections, not gross charges. Gross charges are the amounts billed before contractual adjustments. Net collections are what the practice actually receives after insurance write-offs, contractual discounts, and patient payments. Calculating overhead against gross charges understates the overhead rate and makes the practice look more efficient than it is. Net collections is the only figure that reflects actual revenue the business has to work with.

Why does adding a new provider sometimes not improve income?

A new provider brings revenue but also brings direct expenses: a dedicated medical assistant, higher supply costs, possibly additional space, EHR licensing, and credentialing costs. If those expenses grow at the same rate as the provider's collections, the practice's overhead percentage stays constant and the owner's take-home does not improve. The practices that benefit from adding providers are those that evaluate which overhead costs are truly incremental versus which ones can be absorbed by existing infrastructure before the hire is made.

How do I calculate overhead per provider?

Divide total practice overhead (all expenses excluding provider compensation) by the number of active providers. This reveals the infrastructure cost each provider must cover through their collections before generating profit. If total overhead is $840,000 across three providers, each provider must collect at least $280,000 before their collections contribute anything to provider income. A provider collecting $320,000 generates only $40,000 in margin before their own compensation. That calculation tells you exactly how much provider compensation is affordable at current overhead levels.

When should a medical practice consider outsourcing billing?

Consider outsourcing billing when: your internal billing cost exceeds 6% of collections, your net collection rate is below 95%, denials are taking more than 30 days to resolve, or your billing team spends time on tasks that have no direct impact on claim submission or denial recovery. The comparison should always be total-cost: internal team salary, benefits, software, and clearinghouse fees versus the outsourced fee, evaluated against the collection rate each arrangement produces. A more expensive outsourced solution that adds two percentage points to the collection rate typically generates more revenue than it costs.
