Reading Your Practice P&L: Benchmarks by Specialty

Every practice P&L looks the same at first glance: revenue on top, expenses below, net income at the bottom. What separates a healthy practice from one drifting into trouble is not the format of the P&L; it is the ratios inside it. A 60% overhead ratio looks alarming in a dermatology practice and looks normal in a primary care office. Reading a medical P&L means reading it against the right specialty benchmark, not against a generic small-business standard.

For a physician-owner in Idaho Falls, Twin Falls, or Provo, learning to read the P&L quickly each month is one of the highest-leverage skills there is. This piece covers the six ratios that matter most, how they differ by specialty, why trend beats snapshot, and the warning signs worth acting on before the year closes.

The Six Ratios That Matter Most on a Practice P&L

Six ratios do most of the work of reading a medical P&L:

• Provider compensation as a percentage of net collections
• Non-provider staff payroll as a percentage of net collections
• Occupancy (rent, utilities, common area) as a percentage of net collections
• Medical supplies as a percentage of net collections
• Total overhead (everything except provider comp) as a percentage of net collections
• Net operating income before physician distributions as a percentage of net collections

Every specialty has a range for each. The point is not to hit an exact number; it is to know when a ratio has drifted materially outside its normal range for the specialty and to understand why before the drift becomes structural.

How Overhead Differs by Specialty

Overhead percentage is the single most misread number on a medical P&L. General surgery and orthopedics typically run lower overhead because their per-visit revenue is high. Primary care and pediatrics run higher overhead because their per-visit revenue is lower and staff-intensive workflows are the same either way.

Dermatology and dentistry sit differently again, with higher supplies and equipment ratios but often lower staff ratios. Comparing a primary care practice’s overhead percentage to a dermatology benchmark is not useful; comparing it to peer primary care practices is.

Provider Compensation as a Percentage of Revenue

Provider comp is a management ratio, not a cost ratio. What matters is not whether the number is high, but whether the practice is producing the revenue to support it. A provider comp percentage rising while collections are flat is one of the earliest signs that the compensation model has drifted out of alignment with production.

In a physician-owner practice, this number includes the owner’s own take. Reading it monthly forces a conversation about what the practice is actually leaving to reinvest, and whether the current pace of distributions is sustainable through a slow quarter.

Reading Trend, Not Snapshot

A single month’s P&L is noise. Vacations, seasonal patient patterns, and payer timing all move the numbers around. Trend is signal.

The most useful view is a rolling three-month average of each key ratio, laid alongside the same period twelve months prior. A ratio moving 1 to 2 percentage points month over month is normal. A ratio moving 3 to 5 percentage points over a rolling three-month window is a real change and worth an owner conversation.

Practices that read the P&L this way catch drift while there is time to respond. Practices that only look at the annual number see the drift after it has already compounded.

The Warning Signs to Act on This Quarter

Four patterns show up on a P&L before they show up in cash:

Staff payroll rising as a percentage of collections without a corresponding rise in patient volume usually means either wage inflation the practice absorbed without adjusting prices or fee schedules, or an FTE creep that snuck up over a few hires.

Medical supplies rising faster than revenue often means either genuine cost inflation from vendors or a workflow change that shifted the mix toward higher-supply procedures. Both deserve a look.

Occupancy rising as a percentage of revenue is almost always a revenue problem, not a rent problem. Rent is fixed; the ratio moves because the numerator moved.

Net operating income compression without a specific line item cause usually means a slow drift across three or four accounts, none large enough to notice individually. That is the version worth the closest look, because the fix is workflow rather than a single vendor renegotiation.
