How it works
How the session fee math works
Many clinicians set their fee by looking at what colleagues charge. That tells you what the market accepts, not what your practice needs. This calculator starts from the income you want to take home and works back to the fee that pays for it, after the costs of running a practice, the tax bill, and the hours that end up empty.
Three things push the number up that are easy to forget: weeks you don't work (vacation, holidays, sick days, conferences), sessions that no-show or cancel late without a fee, and sliding-scale sessions that bring in less than your full fee.
Paid sessions = sessions per week × weeks worked × (1 − no-show %)
Profit before tax = take-home goal ÷ (1 − tax %)
Gross revenue needed = profit before tax + business expenses
Average fee = gross revenue needed ÷ paid sessions
Full fee = average fee ÷ (1 − sliding-scale share × discount %)
Assumption: the tax set-aside is applied to profit (revenue minus business expenses), so your take-home goal is what's left after setting aside that share of profit. Your real tax depends on your situation.
Example
A counselor wants to take home $80,000 and sets aside 25% for taxes, so the practice needs $106,666.67 of profit. Add $18,000 of expenses (office rent, license renewal and CE, liability insurance, EHR, supervision and marketing) and the year has to bring in $124,666.67. Holding 20 sessions a week for 46 weeks with an 8% no-show and late-cancel rate means 846.4 paid sessions. That's an average of $147.29 per paid session. With 10% of sessions on a sliding scale at 40% off, the average is 96% of the full fee, so the full fee is $147.29 ÷ 0.96 = $153.43.
At a current full fee of $150, the same caseload collects $144 per paid session on average, or $121,881.60 a year. After expenses and the 25% set-aside, that's $77,911.20 of take-home pay, $2,088.80 short of the goal.
Want to track whether your real caseload hits that fee every month? The Private Practice Business System has a Fee & Caseload Calculator tab, plus a session log, income and expenses with a tax set-aside, and a goal planner.
