You spent four years in medical school, three to seven years in residency, and possibly a fellowship after that. At no point did anyone teach you how to read a balance sheet. Now you own a practice, you are responsible for a multi-million-dollar business, and your CPA sends you financial statements that might as well be written in a foreign language.
You are not alone. Most physician owners glance at revenue on the P&L, check their bank balance, and move on. That is like diagnosing a patient by checking their pulse and nothing else. You might catch the obvious problems, but you will miss everything else until it is too late to treat.
This guide walks through each of the three core financial statements, explains what each line item means in the context of a medical practice, and shows you how to read them together to get the full picture of your practice's financial health. Budget 15 minutes. It will be the most valuable quarter-hour you spend this month.
Statement 1: The Profit & Loss Statement (P&L)
The P&L, also called the income statement, answers one question: did the practice make or lose money during this period? It covers a specific timeframe, usually a month, quarter, or year.
The structure
Every P&L follows the same basic structure: Revenue minus Expenses equals Net Income. Here is what each section means for a medical practice.
Revenue (the top section)
Gross charges: The total amount you billed at your full fee schedule rates. This number is almost meaningless by itself because no one pays full charges. Think of it as your sticker price.
Contractual adjustments: The difference between your charges and what your payer contracts say you will actually be paid. If you bill $200 for a visit and Blue Cross's contracted rate is $130, the $70 difference is a contractual adjustment. This is normal and expected. It is not lost revenue; it is revenue you were never going to collect.
Net revenue (net collections): Gross charges minus contractual adjustments, minus any bad debt write-offs. This is the real number. When someone asks 'what does your practice do in revenue,' this is the answer. For a four-physician primary care practice, you might see net revenue of $2.5-$4 million annually. For a surgical specialty practice, it could be $5-$10 million or more.
Expenses (the middle section)
This is where most practice owners stop reading too quickly. Expenses typically break into several categories.
Staff compensation and benefits: This is usually the largest single expense, representing 25-32% of net collections for a well-run practice. It includes salaries, wages, payroll taxes (7.65% for the employer's share of FICA), health insurance, retirement plan contributions, and any bonuses. If this line exceeds 35% of collections, you are either overstaffed, overpaying, or both relative to your volume.
Provider compensation: For employed providers (non-owner physicians, NPs, PAs), this includes salary, productivity bonuses, and benefits. Owner compensation may or may not appear here, depending on the entity structure. In an S-corp, owner compensation shows as both salary (on the P&L) and distributions (not on the P&L). In a partnership, it may all flow through as distributions. Understanding where owner comp appears is critical to interpreting the P&L accurately.
Occupancy costs: Rent, utilities, property taxes, building insurance, maintenance. Target range: 5-8% of net collections. If you own the building through a separate entity and lease it back to the practice, make sure the lease rate is at fair market value. We frequently see practices paying above-market rent to a physician-owned real estate LLC, which deflates the practice's profitability and inflates the real estate entity's income.
Medical supplies and drugs: Highly variable by specialty. A dermatology practice using expensive biologics will have a much higher percentage here than an internal medicine practice. Track this as a percentage of revenue and monitor the trend.
Billing and collections costs: If outsourced, this typically runs 5-8% of collections. If handled in-house, the costs are embedded in staff compensation and technology expenses. Either way, know what you are paying and benchmark it.
Professional fees: Legal, accounting, consulting. Should be 1-2% of revenue in a normal year. If it is significantly higher, you are either in the middle of a transaction (which is temporary) or paying for services you do not need.
Depreciation and amortization: This is a non-cash expense that represents the wearing out of your equipment and the expensing of intangible assets over time. It reduces your taxable income without reducing your cash. Keep this in mind when comparing your P&L profit to your bank balance; depreciation is one reason they diverge.
Net income (the bottom line)
Revenue minus all expenses. For physician-owned practices, 'healthy' net income varies enormously depending on whether owner compensation is included in expenses. If owners take salary, net income represents the profit above and beyond owner comp. If owners take only distributions, net income is effectively owner comp plus profit. Always ask: does the net income number include or exclude owner pay?
What to look at first on the P&L
Step 1: Compare this month to the same month last year. Is revenue up or down? By how much? Seasonal variations are normal (February is always low, January sees a bump from deductible resets), so month-over-month comparisons can be misleading.
Step 2: Calculate your overhead ratio: total expenses (excluding owner/provider compensation) divided by net revenue. If it is above 65%, you need to investigate. Pull out the top five expense categories and check each one as a percentage of revenue against benchmarks.
Step 3: Look at the trend over the last 12 months. A single month is a data point. Twelve months is a story. Is revenue growing? Are expenses growing faster than revenue? Is the overhead ratio creeping up?
Statement 2: The Balance Sheet
The balance sheet answers a different question: what does the practice own, what does it owe, and what is left over? Unlike the P&L, which covers a time period, the balance sheet is a snapshot of a single moment, like a photograph instead of a video.
The equation
Assets = Liabilities + Equity. Always. If it does not balance, something is wrong with the bookkeeping.
Assets (what you own)
Cash and cash equivalents: Money in the bank. The number you probably check most often. For a healthy practice, you should have enough cash on hand to cover 4-8 weeks of operating expenses. If you consistently carry less than two weeks, you are operating dangerously close to the edge.
Accounts receivable (A/R): Money owed to you by insurance companies and patients. This is typically the largest asset on a practice's balance sheet. For a practice collecting $300,000 per month with 35 days in A/R, total A/R should be roughly $350,000. If total A/R is $500,000, you are either billing more than you are collecting (A/R is growing, which is a problem) or your days in A/R are too high (also a problem).
Prepaid expenses: Amounts you have paid in advance for future services, such as malpractice insurance premiums or annual software licenses. These are assets because you have already paid but have not yet received the benefit.
Fixed assets (net of depreciation): Equipment, furniture, leasehold improvements, at their original cost minus accumulated depreciation. A $200,000 CT scanner that is five years into a seven-year depreciation schedule has a book value of about $57,000. Important note: book value has nothing to do with market value. That scanner might be worth $80,000 on the used equipment market or it might be worth $20,000. The balance sheet tells you the accounting value, not the selling price.
Liabilities (what you owe)
Accounts payable (A/P): Bills you have received but not yet paid. Supply invoices, utility bills, professional fees. Normal A/P for a medical practice is usually 2-4 weeks of operating expenses. If A/P is growing and you are stretching payments beyond terms, that is a cash flow red flag.
Accrued expenses: Obligations you have incurred but have not been billed for yet: accrued payroll (wages earned by employees between the last pay date and the end of the reporting period), accrued paid time off, and accrued taxes.
Current portion of long-term debt: The amount of your loans that is due within the next 12 months. This is the principal portion of your debt payments for the coming year.
Long-term debt: Equipment loans, practice acquisition loans, building mortgages, lines of credit. The balance after subtracting the current portion.
Equity (what is left)
Assets minus liabilities. This represents the owners' residual interest in the practice. In a single-owner practice, equity includes your original investment, accumulated retained earnings (profits not yet distributed), and any additional capital contributions, minus any distributions you have taken.
Key insight: If equity is negative, the practice owes more than it owns. This is not automatically a crisis (many practices carry significant debt for good reasons), but if equity has been declining for several consecutive periods, the practice is on a path toward insolvency.
What to look at first on the balance sheet
Step 1: Check the current ratio: current assets divided by current liabilities. This measures short-term liquidity. A ratio above 1.5 means the practice can comfortably cover its near-term obligations. Below 1.0 means current liabilities exceed current assets, which is a liquidity problem.
Step 2: Compare A/R to revenue. If A/R is growing faster than revenue, collections are slowing down. This is one of the earliest warning signs of cash flow trouble, and it shows up on the balance sheet before it shows up in your bank account.
Step 3: Look at the debt-to-equity ratio. Total liabilities divided by total equity. For a practice, anything under 2.0 is generally comfortable. Above 3.0, you are highly leveraged and vulnerable to any downturn in revenue.
Statement 3: The Cash Flow Statement
The cash flow statement answers the most practical question of all: why did the bank balance go up or down? It reconciles the P&L profit (which includes non-cash items) to the actual change in cash.
The three sections
Operating activities: Cash generated by (or used in) the day-to-day operations. This starts with net income from the P&L and then adjusts for non-cash items (adds back depreciation, accounts for changes in A/R, A/P, and other working capital). This is the most important section. If operating cash flow is consistently positive and exceeds net income, the practice is converting profits into cash effectively. If operating cash flow is consistently negative despite a profitable P&L, you have one of the problems discussed in the sections above.
Investing activities: Cash spent on (or received from) long-term investments. For a practice, this is primarily equipment purchases. If you bought a $150,000 piece of equipment, it shows up here as a $150,000 cash outflow, even though the P&L only reflects $21,000 in depreciation for the year. This is a major reason your bank balance can drop dramatically in a year when your P&L looks profitable.
Financing activities: Cash from loans (inflows) and used for loan repayments and owner distributions (outflows). If you took a $200,000 equipment loan, the $200,000 shows as an inflow here. The $40,000 annual principal payment shows as an outflow. Only the interest on that loan appears on the P&L. The principal repayment is invisible on the income statement but very real on the cash flow statement and in your bank account.
What to look at first on the cash flow statement
Step 1: Is operating cash flow positive? If not, the practice is burning cash from operations, which is not sustainable regardless of what the P&L says.
Step 2: Is operating cash flow greater than net income? If yes, the practice is efficiently converting profits into cash. If operating cash flow is significantly less than net income, the difference is almost always explained by A/R growth (you are billing faster than you are collecting) or A/P reduction (you are paying bills faster than you are accruing expenses).
Step 3: What is happening in financing? Large distributions (outflows) combined with increasing debt (inflows) is a warning pattern. It means the practice is borrowing to fund distributions, which is unsustainable.
Reading the Three Statements Together
Each statement gives you one dimension. Together, they give you the full picture.
Scenario 1: P&L shows profit, balance sheet shows growing A/R, cash flow shows negative operating cash. Diagnosis: the practice is profitable on paper but is not collecting what it bills. Cash is being consumed by A/R growth. Treatment: fix the billing and collections process.
Scenario 2: P&L shows profit, balance sheet looks healthy, cash flow shows large investing outflows. Diagnosis: the practice just made a major equipment purchase. Cash is down but for a good reason (assuming the investment generates returns). Treatment: monitor whether the new equipment generates the expected volume and revenue.
Scenario 3: P&L shows declining margins, balance sheet shows growing debt, cash flow shows distributions exceeding operating cash. Diagnosis: the practice is over-distributing, covering the gap with debt, and margins are compressing. Treatment: reduce distributions immediately, restructure debt if possible, and address the margin compression.
You do not need to be an accountant to read these statements effectively. You need to know which numbers to look at, what they mean, and what patterns to watch for. Spend 15 minutes each month with all three statements in front of you. Compare to prior periods. Look for trends. When something looks off, ask your CPA or CFO to explain it. The question itself is often more valuable than the answer, because it forces the conversation that keeps small problems from becoming big ones.
