Quick Answer
Monthly overhead for a solo private practice runs $500 to $2,500 once established. Heard's 2025 data shows the average solo practitioner earns $127,631 in revenue with a 72% margin, taking home $86,961 before personal taxes. Startup costs typically run $3,000 to $10,000. The biggest variable is office rent. Software costs are the fastest-growing line item.
1The headline numbers
Heard publishes an annual Financial State of Private Practice report that gives the clearest picture of what private practice actually looks like financially. The 2025 numbers:
That 28% overhead gap between gross and take-home is what we are talking about when we say "the cost of running a practice." On $127,631 in revenue, that is roughly $40,000 per year in operating costs, or about $3,300 per month.
A few caveats before we go further:
- These are averages. A therapist in a rural area with a home office has a completely different cost structure than one renting in a downtown Toronto or Manhattan high-rise.
- Take-home is before personal income taxes. After self-employment tax and income tax, the actual net figure is lower, typically $55,000 to $70,000 for a therapist at this revenue level.
- Therapists who elect S-Corp status show slightly lower margins (64.4%) due to payroll administration costs, but typically save on self-employment taxes overall.
- These numbers skew toward established practices. A therapist in their first year will likely show higher overhead as a percentage of revenue because fixed costs eat up a larger share of a smaller caseload.
With that context, here is what the actual line items look like.
2What it actually costs to launch
Startup costs are one-time or first-year expenses that do not recur. Most therapists can launch for $3,000 to $10,000. Here is what that breaks down to:
| Expense | Low | High | Notes |
|---|---|---|---|
| Business registration | $100 | $500 | Varies by province/state |
| Professional liability insurance (first year) | $300 | $800 | Higher for psychologists |
| Professional association fees (first year) | $200 | $500 | CRPO, OPA, CAMFT, etc. |
| Licensing / registration renewal | $200 | $600 | If not already licensed |
| Office setup (furniture, supplies) | $500 | $3,000 | Higher if building from scratch |
| Office first/last month deposit | $0 | $3,000 | $0 if subletting or home office |
| EHR setup and first year | $0 | $600 | Some platforms are free to start |
| Website (DIY vs. professional) | $200 | $3,000 | Squarespace vs. custom build |
| Business bank account, bookkeeping setup | $0 | $300 | Many banks are free to open |
| Phone line (business) | $0 | $200 | Google Voice vs. dedicated line |
| Total | $1,500 | $12,500 | Typical: $3,000–$8,000 |
The lowest-cost launch path: subletting an office from an established therapist (no deposit, pay by the session), using a free-tier EHR, building your own website on Squarespace, and forgoing a dedicated business phone. Many therapists launch this way and are profitable by month three or four.
The higher-cost path is often over-built for the early stage. A custom website for a therapist with a caseload of five is hard to justify. Defer the expensive version until you have the caseload to pay for it.
3Monthly operating costs
Once you are running, the cost structure settles into a predictable set of recurring expenses. These are the items you pay every month regardless of how many clients you see.
| Category | Low | High | What drives cost |
|---|---|---|---|
| Office rent | $0 | $2,500 | Home vs. sublet vs. dedicated space |
| Malpractice insurance | $25 | $100 | License type, coverage amount |
| Professional association dues | $25 | $75 | Prorated annually |
| EHR / practice management software | $30 | $150 | SimplePractice, Jane, TherapyNotes |
| Billing (if accepting insurance) | $0 | $150 | DIY vs. biller or clearinghouse |
| Website hosting + domain | $20 | $60 | Squarespace, Wix, or custom |
| Continuing education | $50 | $200 | Averaged monthly from annual spend |
| Supervision (early career) | $0 | $400 | Pre-registration or consultation |
| Accounting / bookkeeping | $0 | $150 | DIY vs. bookkeeper |
| Phone (business line) | $0 | $50 | Google Voice vs. VoIP service |
| Miscellaneous (supplies, Kleenex, etc.) | $20 | $80 | Office consumables |
| Total monthly overhead | $170 | $3,915 | Typical: $800–$2,000 |
Office rent is the single biggest variable. A therapist working from home or subletting a room two days a week can run a full caseload at $170 to $500 per month in fixed overhead. Someone renting a dedicated suite in a professional building will be at $1,500 to $2,500+ before any other costs.
The break-even math: If your total monthly overhead is $1,500 and you charge $150 per session, you need 10 billable sessions per month before you start paying yourself. At $180/session, that drops to 9 sessions. Most therapists target 20-22 billable sessions per week for a comfortable full-time income after accounting for cancellations and slower periods.
4The software stack problem
Software is the fastest-growing cost category for private practice therapists, and most therapists underestimate it badly.
The average private practice now uses 5 to 7 paid software tools. You add them one at a time, each solves a real problem, and six months later you are paying $350 to $500 per month for software you may not be fully using.
Here is a realistic software stack audit for a solo practice:
| Tool category | Examples | Typical cost/mo |
|---|---|---|
| EHR / practice management | SimplePractice, Jane App, TherapyNotes | $39–$99 |
| Telehealth (if not included) | Zoom for Healthcare, Doxy.me | $0–$50 |
| Scheduling (if not included) | Calendly, Acuity | $0–$16 |
| Secure messaging | Signal, Klara, OhMD | $0–$30 |
| Documentation AI | AI SOAP notes, Mentalyc, Upheal | $29–$149 |
| Worksheet / session materials | TherapistAid, Reframe Practice | $0–$29 |
| Website hosting | Squarespace, WordPress, Wix | $20–$60 |
| Email marketing (if newsletter) | Mailchimp, Beehiiv | $0–$29 |
| Accounting | QuickBooks, Wave, Heard | $0–$30 |
| Realistic software total | $88–$492 | |
The discipline here is consolidation. If your EHR includes telehealth and scheduling, you do not need separate tools for those. Some platforms (like Jane App) include telehealth, scheduling, billing, and a basic client portal in one subscription. Running parallel tools for the same function is where costs compound unnecessarily.
Do a quarterly software audit. Pull your bank and credit card statements, list every subscription, and ask whether you used each tool meaningfully in the last 30 days. Most therapists find at least one or two subscriptions they forgot about or could consolidate.
5Insurance vs. private pay: The income math
This deserves its own section because the income gap is larger than most therapists expect before they run the numbers.
At 20 sessions per week, that gap adds up to $19,200 per year in gross revenue. Before you factor in the administrative cost of billing insurance.
Insurance billing adds costs that private pay does not have:
- Time spent on prior authorizations (avg 2-4 hours per week at busy insurance practices)
- Billing staff or outsourced billing service ($50-$150/month for a solo practice)
- Denied claims management and appeals
- Slower cash flow (insurance typically pays 30-90 days after service)
- Diagnosis exposure (insurance creates a permanent record of diagnoses)
The argument for staying on panels despite the income gap: a full caseload is easier to build when you accept insurance. Clients paying out of pocket are a smaller pool. Some therapists start on panels to build caseload, then slowly transition to private pay or out-of-network as their reputation grows.
For cost purposes, the key point is that the insurance model is not free. It trades lower per-session income for a more accessible client pool, and adds administrative overhead that reduces the effective hourly rate further. The full decision framework is a longer conversation, but the numbers above are what you are working with.
6Revenue benchmarks by practice stage
Practice economics look different depending on where you are. Here are realistic benchmarks for each stage:
Launch year (0-12 clients/week)
$8,000–$36,000 take-homeFixed costs eat a larger share. Profitability depends on keeping overhead low.
Building phase (12-20 clients/week)
$36,000–$70,000 take-homeRevenue is growing but overhead stays flat. Margin improves significantly.
Established practice (20-25 clients/week)
$65,000–$105,000 take-homeThis is where Heard's 72% margin average shows up. Overhead is largely fixed.
Expanded practice (group, associates)
Variable take-homeAdding staff reintroduces overhead. The economics depend on associate fee splits.
The jump from building phase to established practice is where private practice becomes genuinely more lucrative than agency work. Below 15 clients per week, the comparison is less clear-cut because benefits from agency employment have real value.
7Where therapists waste money (and where to invest)
The data from Heard and from therapist communities shows predictable patterns in both directions. Some costs therapists routinely overspend on. Others are chronically underfunded.
Common money drains
Psychology Today at full price, too long
PT costs about $360/year. In a healthy market, that pays for itself easily. But PT referrals dropped 77-94% for many therapists between 2023 and 2025. If you have not gotten a new client from PT in 90 days, the ROI is negative. Reassess annually.
Premium EHR features you do not use
SimplePractice's top tier adds telehealth, payroll, and other features that a solo practice rarely needs. The base tier at $39/month handles most solo practitioners. Audit what you are actually using before upgrading.
Overlapping documentation tools
Many therapists pay for both a documentation AI tool and a notes feature inside their EHR. Pick one workflow and stick with it. Paying for two documentation systems that do the same job is a common drift cost.
Website rebuilds before building traffic
A $5,000 website for a practice with no SEO strategy is a decoration, not a business asset. Invest in traffic first. A functional $500 site with good SEO will outperform a beautiful $5,000 site that no one finds.
Rates set too low at launch
This is not a cost you can see on a spreadsheet, but it is the most expensive mistake. Every month you bill at $120 when you should be at $150 costs you $240-$600/week in lost revenue. Set your rate based on your costs and the market, not on what you think clients can afford.
Worth the investment
Your website (once you have traffic strategy)
A therapist website with solid local SEO will outperform any directory in the long run. The initial investment pays back in reduced directory fees and higher-quality client inquiries.
Documentation tools that save clinical time
If a $29/month tool genuinely cuts your note-writing from 15 minutes to 3 minutes per session, and you see 20 clients a week, that is 4 hours per week back. At $150/hour in billable time, that tool pays for itself in under a day each month.
Consultation and supervision (even post-registration)
Peer consultation makes you a better clinician and a more referrable one. The ROI is indirect but real. A therapist who participates in consultation groups gets referrals from those networks.
Specialty training in high-demand areas
EMDR certification, somatic training, or perinatal mental health specialization typically commands a $20-$40/session premium. The CE cost is recovered in a few months at higher rates.

Frequently asked questions
How much does it cost to run a private therapy practice?
Monthly operating costs for a solo therapy practice typically range from $500 to $2,500 once established. Heard's 2025 data shows the average solo practitioner generates $127,631 in revenue with a 72% margin, taking home $86,961 before personal taxes. Startup costs typically run $3,000 to $10,000.
How much does it cost to start a therapy practice?
Startup costs for a therapy practice typically run $3,000 to $10,000 for a standard launch. Therapists subletting office space and using a free or low-cost EHR can launch for under $2,000. The biggest variables are office setup costs and whether you build a custom website or use a template platform.
What are the biggest ongoing expenses for therapists in private practice?
For most solo therapists: office rent ($400-$1,500/month), malpractice insurance ($25-$80/month), EHR software ($30-$150/month), continuing education ($100-$200/month averaged), and professional association fees ($25-$75/month). Software costs have grown as the number of practice management tools has multiplied.
How much do private practice therapists make after expenses?
According to Heard's 2025 report, the average solo private practice therapist earns $127,631 in gross revenue and takes home $86,961 after practice expenses, before personal income taxes. The margin is approximately 72% for sole proprietors.
Is private practice more profitable than agency work?
For most experienced therapists, yes. Agency salaries typically range from $45,000 to $75,000 with benefits. Private practice gross revenue averages $127,631 with $86,961 take-home before taxes. The break-even point is typically 12-15 clients per week at private pay rates. Below that volume, agency work may be more financially stable.
How many clients do I need to cover my expenses?
Divide your monthly overhead by your per-session fee. If your overhead is $1,500 and you charge $150/session, you need 10 billable sessions per month to break even. Most therapists target 20-22 billable sessions per week for a sustainable full-time income after accounting for cancellations.
What software do private practice therapists need?
The core stack: an EHR with scheduling and notes ($30-$150/month), telehealth if offering virtual sessions ($0-$50/month, often included in EHR), a website with booking ($20-$60/month), and billing support if accepting insurance ($0-$100/month). Total software commonly runs $90-$300/month for a well-equipped solo practice.
What is the biggest financial mistake therapists make in private practice?
Setting rates too low at the start and struggling to raise them later. The second most common mistake is letting software costs drift. The average practice quietly accumulates 5-7 paid subscriptions. A quarterly audit catching one unused tool typically saves $30-$60/month.
