Setting Your Session Rate: The Arithmetic Most Therapists Skip

Most therapists set their rate by triangulation: what the therapist down the hall charges, what feels defensible, what a supervisor charged in 2019. The arithmetic below takes twenty minutes and replaces that with a number derived from your actual life. Five steps.

Step 1: Name the income you need, pre-tax

Start with the take-home you need annually, then work backward. Self-employment means the costs an employer once carried are now yours: both halves of Social Security and Medicare, your own health insurance, and your own retirement contributions. There is no single multiplier that fits every situation, but the pre-tax figure that produces a given take-home is always meaningfully larger than the take-home itself — an accountant can pin your number in one conversation. Write the pre-tax figure down. That is the revenue your clinical work must produce for you personally.

Step 2: Add the practice's overhead

Everything the practice consumes before you are paid:

• Office rent, or your telehealth setup.
• EHR, phone, scheduling, and website costs.
• Liability insurance, licensure, and continuing education.
• Supervision or consultation.
• Card-processing fees on the payments themselves.
• Bookkeeping, accounting, and legal.

Total it annually. (Starting from zero? The practice startup cost calculator itemizes the first-year version of this list.) Step 1 plus Step 2 is your required annual revenue.

Step 3: Count the sessions you will actually hold

This is the step most rate-setting skips, and it is where rates go wrong:

1. Clinical weeks, not 52. Subtract vacation, holidays, sick time, and conference weeks. For many solo practices the honest number lands in the mid-40s.
2. A sustainable weekly caseload, not a maximal one. Every clinical hour drags admin time behind it — notes, billing, emails, coordination. The number you can sustain for years is the one that belongs in this equation; our guide to how many clients per week works through finding it.
3. A realistic show rate. Some scheduled sessions will not happen and will not be paid — no-shows you waive, late cancels, holds for clients who pause. Discount your scheduled count by whatever your own attendance history shows.

Clinical weeks × weekly sessions × show rate = sessions per year. For a fuller treatment of what each held session must earn, see revenue per session.

Step 4: Divide, then look at a worked example

A hypothetical, purely to show the shape of the math (the specific numbers are illustrative, not benchmarks):

Note what the result is: the average each held session must earn. If part of your caseload is insurance at contracted allowables below that average, your private-pay rate has to sit above it to compensate — the blend has to hit the number, not any single fee. The session rate calculator runs this whole chain interactively, including the insurance blend.

Step 5: Sanity-check, then commit

Now — and only now — look outward. Compare your derived number against what experienced clinicians with your training charge in your market. If your number is far above market, the equation says your costs or income target need work, or your practice needs a niche that commands the difference. If it is below market, you have room. Either way you are adjusting from arithmetic, not anxiety. If the exercise shows your current rate is too low, raise it properly — the rate increase letter covers notice and script — and if you want to keep access for lower-income clients while holding your number, do it deliberately with a structured sliding scale rather than by quietly under-charging everyone. Then put the review on your calendar: rerun this arithmetic once a year, because overhead and life both drift.
