The one number every practice owner should know, and how to find it

There is one number that tells you whether your practice is actually working for you financially, no matter how busy the schedule is or how happy your clients are.

Most practice owners don't know it. They know revenue, what comes in. They have a rough feel for expenses. They can tell you if last month was "good" or "slow." What they can't tell you, without stopping to do math they don't usually do, is whether the practice is generating the money they need to keep going, pay themselves fairly, and build toward something.

That number is your practice net after a real owner draw.

It sounds simple. The catch is a calculation almost everyone gets wrong.

What mistake do most owners make?

The common version goes like this: revenue minus expenses equals profit. You keep whatever's left.

The problem is that this calculation treats your own pay as a residual: something left over after everyone else is covered. In most small practices, the owner's pay isn't a formal line item. It's whatever's in the account at the end of the month. And when it's put that way, the math is almost always flattering: the practice looks more profitable than it is, because your labor isn't being counted.

The honest version starts with what the practice would have to pay someone else to do what you do. Not every owner does clinical work, admin, billing, and business development, but many do, or something close to it. That labor has a market rate. If you're not paying yourself at least a version of that rate, you're subsidizing the practice with your own time. The books look fine. You're quietly underpaid.

The number to find

Here is the calculation, in plain terms:

Revenue (what actually came in: collected, not billed)
minus your operating expenses (everything the practice pays to stay open)
minus a real owner draw (what you'd pay a competent person to do your job)
equals the practice's true profit after supporting you.

If that last number is positive, the practice is actually working. If it's negative, even if it looks like the practice is breaking even, the practice is only surviving because you're not paying yourself what your time is worth.

This is the number that tells you whether you can afford your next hire, and whether the practice leaves you a life outside it.

Why is this harder than it looks?

Two things make this calculation harder to do than it sounds.

The first is that "collected revenue" is different from what your billing software shows. If you bill $10,000 in a month and collect $8,500, your practice generated $8,500 that month. Some of the $1,500 gap is no-shows, cancellations, insurance adjustments, and write-offs; some is claims still in process that land next month. The part that never arrives was never income, and starting from billed-but-not-collected inflates the number either way.

The second is that most owners have never put a number on what their own labor is worth. It's an uncomfortable question, but the calculation doesn't work until you answer it.

A starting point: what would a competent operations person cost at your level of responsibility? What would a therapist at your clinical level bill? Those aren't the exact number, but they're anchors. What you pay yourself should be grounded in something other than "what's left."

One useful exercise

Take last month's collected revenue. Subtract what you actually spent: payroll (everyone except you), rent, software, insurance, everything. Then subtract a real draw for yourself: what you'd want to be making if this practice were healthy and the numbers worked.

What's left?

If it's meaningfully positive, you have a practice that can grow. If it's close to zero, the practice is running on your unpaid labor. If it's negative, something has to change before more time goes by: rates, caseload, cost structure, or compensation.

This number doesn't solve every problem. It doesn't tell you which clinician is losing money or whether your rates are right. But it is the starting point, and it takes one bank statement and ten minutes.
