Medical practice financial statements: What every owner-doctor should review monthly

Your accountant emails the monthly financials. You open the P&L, glance at the bottom line, confirm the practice made money, and close the file. The balance sheet goes unopened. The cash flow statement might as well not exist. You spent eight years in medical school and residency learning to interpret lab results, imaging studies, and clinical data with precision. But the three documents that diagnose your business's financial health get a five-second scan at best.

This is not a criticism. Nobody taught you how to read financial statements in the context of running a medical practice. The standard P&L, balance sheet, and cash flow statement were designed for general business. Interpreting them for a practice with insurance AR, provider compensation structures, and payer mix dynamics requires knowing which lines matter, which ratios to calculate, and which trends to watch.

Here is what each statement tells you and exactly how to read it as a practice owner.

Three financial statements at a glance: what each shows and the key number to track

The income statement: Where your money comes from and where it goes

The income statement (also called the P&L or profit and loss) shows revenue, expenses, and net income for the month. For a deeper look at how a P&L is structured and what each line represents, the guide to the profit and loss statement provides detailed coverage. For a medical practice specifically, the standard format needs to be modified to be useful.

Revenue should show net collections, not gross charges. If your P&L shows $480,000 in revenue, that number should represent cash collected, not services billed. Gross charges minus contractual adjustments minus write-offs equals net collections. If your P&L shows gross charges as revenue with adjustments buried further down, the top line overstates the practice's actual income, and every ratio calculated from it will be distorted. For how net collections compare to gross charges across different payer types, and for which collection rates to benchmark, the guide to medical practice collections provides payer-by-payer benchmarks.

Revenue should be segmented by payer category. Break revenue into Medicare, Medicaid, commercial insurance, self-pay, and ancillary services. This reveals your payer mix and lets you track whether collection rates by payer are stable or declining.

Expenses should be separated into clinical and administrative. Clinical expenses (supplies, lab costs, clinical staff, medications) relate to patient care. Administrative expenses (front desk, billing, office supplies, technology, rent) relate to operations. This separation allows you to calculate the clinical cost per patient visit and the administrative cost per provider.

Provider compensation should appear as its own section. Owner compensation, associate salaries, bonuses, benefits, and malpractice should be grouped separately from staff expenses. This lets you see operating margin before provider compensation (how much the practice generates to pay providers) and net margin after all compensation (true profitability).

The three numbers to check every month on the P&L

1. Net collections compared to the same month last year and to the budget. Is revenue growing, flat, or declining?

2. Total overhead as a percentage of collections. Target: 55% to 65%. According to a June 2025 MGMA Stat poll, 90% of medical groups reported that their operating costs were higher in 2025 than at the same point in 2024. Trending overhead is the earliest visible indicator of margin pressure. For category-level benchmarks on where overhead concentrates, the guide to medical practice overhead lists the categories that most commonly exceed the benchmark.

3. Net income as a percentage of collections. This is your bottom-line efficiency. A practice netting 15% after all provider compensation is healthy. Below 10% signals margin pressure.

The balance sheet: What you own, what you owe, and what is stuck in between

Most practice owners skip the balance sheet because it feels abstract. But two sections deserve monthly attention.

Accounts receivable. The AR balance on the balance sheet tells you how much revenue has been earned but not yet collected. More importantly, the trend tells you whether your collection cycle is healthy. AR that grows faster than revenue indicates collections are slowing. AR that holds steady or shrinks relative to revenue means the collection machine is working.

Calculate days in AR monthly (total AR divided by average daily charges). Target: below 40 days. If days in AR increase by more than three to five days from one month to the next, something has changed in your billing or collection process and needs investigation. For a detailed breakdown of how to interpret the accounts receivable aging report that supports this calculation, the glossary entry covers bucket definitions and what each age range signals.

Cash and cash equivalents. This is your operating liquidity. How many months of operating expenses could you cover with the cash on hand? Divide your cash balance by monthly operating expenses (excluding provider compensation). One to two months is adequate. Below one month is a warning. Three months or more provides a comfortable buffer for seasonal dips and unexpected expenses.

Accounts payable and accrued liabilities. If payables grow while cash declines, the practice is stretching vendor payments. This coping mechanism becomes a credit problem if it persists.

The balance sheet question to ask monthly: Is AR growing faster than revenue? If so, your collection cycle is deteriorating, and cash flow problems are approaching, even if the P&L looks healthy. For a step-by-step plan to reduce days in AR and improve collection timing, the guide to healthcare accounts receivable outlines a 90-day process to bring AR days under control.

The cash flow statement: Following the money from P&L to the bank account

The cash flow statement explains why your bank balance changed. This is the statement that answers the question every practice owner asks: "We had a profitable month, so why do we have less cash?"

Operating cash flow. Cash generated from normal operations. This starts with net income and adjusts for non-cash items (depreciation, changes in AR, and payables). Positive means the practice generates more cash than it consumes. Negative means cash is burning despite potential P&L profit.

The most common reason a profitable practice shows negative operating cash flow is growing AR. If you collected $480,000 but AR grew by $60,000, the actual cash inflow was only $420,000.

Investing cash flow. Cash spent on equipment, technology, or leasehold improvements. Large equipment purchases show as a negative here, which is expected and not cause for concern unless purchases consistently exceed cash generation.

Financing cash flow. Loan proceeds, repayments, and owner distributions. Debt taken to fund operations (not equipment) is a warning. Distributions exceeding net income mean owners are extracting more than the practice generates.

The cash flow question to ask monthly: Is operating cash flow positive? If net income is positive but operating cash flow is negative, AR growth or changes in payables are the most likely explanations. Investigate before the trend becomes a cash crisis.

Building a monthly financial review routine

A useful monthly financial review takes 30 to 45 minutes and follows a consistent sequence.

Step 1: Read the P&L top to bottom (10 minutes). Check net collections against budget and prior year. Scan each expense category for unexpected spikes. Calculate the overhead percentage. Note net income margin.

Step 2: Check the balance sheet warning indicators (10 minutes). Calculate days in AR. Check cash balance against monthly expenses. Note any significant changes in payables or accrued liabilities.

Step 3: Review cash flow (5 minutes). Confirm operating cash flow is positive. If negative, identify the cause: AR growth, a large payable payment, or timing of collections.

Step 4: Ask three forward-looking questions (10 minutes).

• Based on this month's data, is revenue trending in the right direction?

• Are there expense categories that need intervention before next month?

• Is the cash position adequate for known upcoming obligations (quarterly taxes, equipment purchases, bonus payments)?

Financial statements are your practice's vital signs

You would never diagnose a patient based solely on their heart rate. You check vitals as a system: heart rate, blood pressure, temperature, respiratory rate, and oxygen saturation. Each number means more in context with the others.

Financial statements work the same way. The P&L without the balance sheet misses the AR and cash story. The balance sheet without cash flow does not explain where the money went. Read all three together, every month, in 30 to 45 minutes. That habit gives you the same diagnostic clarity over your business that you bring to your patients every day.

Frequently asked questions

What is the most important financial statement for a medical practice owner to review monthly?

All three matter, but the balance sheet is the most commonly skipped and the most predictive of coming problems. A P&L that shows profit can coexist with a deteriorating AR balance and a declining cash position. The balance sheet, specifically days in AR and cash coverage, tells you whether the profitable month will translate to cash in the bank or whether a collection problem is building. Read the P&L first, then use the balance sheet and cash flow statement to verify whether the P&L is accurate.

What is a healthy overhead rate for a medical practice?

The standard benchmark is 55% to 65% of net collections. Below 55% is exceptional and rare. Above 65% means expenses consume more than two-thirds of revenue before provider compensation, compressing what the practice can pay its providers. Overhead trending upward over three consecutive months, even within the 55-65% range, deserves investigation before it crosses the threshold.

Why is my practice profitable but short on cash?

The most common cause is growing accounts receivable. If your practice billed and collected less than it charged in a given month, the gap appears as AR growth on the balance sheet. The cash flow statement shows this directly: net income is positive, but operating cash flow is negative because AR grew. Check whether days in AR increased from the prior month and which payer categories are collecting more slowly than usual. A growing AR balance that coincides with a profitable P&L is one of the most misleading combinations in medical practice finance.

How do I calculate days in AR for my practice?

Divide total AR (from the balance sheet) by average daily charges. Average daily charges equal total charges for the last 90 days divided by 90. If your AR balance is $320,000 and your average daily charges are $9,000, the days in AR are approximately 35.6 days, which is below the 40-day target. Calculate this every month and track it as a trend. An increase of more than three to five days between months indicates something has changed in billing, collections, or payer behavior and needs investigation.

How long should a monthly financial review take?

For a typical single-specialty practice, 30 to 45 minutes is sufficient if the financial statements are properly formatted with practice-specific metrics pre-calculated. P&L review takes roughly 10 minutes, balance sheet indicators take 10 minutes, cash flow review takes 5 minutes, and the forward-looking analysis takes the remaining 10 minutes. If the review consistently takes longer than an hour, the statements are not formatted for practice decision-making, or the bookkeeping is producing data that requires reconciliation before it can be read.

What is the difference between gross charges and net collections on a P&L?

Gross charges are the total amount billed to all payers before contractual adjustments, write-offs, or denials. Net collections are the cash actually received after all adjustments. For most medical practices, net collections run between 50% and 80% of gross charges depending on payer mix. A P&L that reports gross charges as the revenue line will show a much larger number than actual income. Every ratio calculated from that revenue figure, including overhead percentage and net margin, will be meaningless. Always confirm that your P&L is built on net collections.
