Introduction
Most therapists opening a private practice underestimate their overhead by $800 to $1,500 per month in the first year. The categories they miss: professional liability insurance renewal, EHR subscription, HIPAA compliance tools, phone and secure messaging, supervision fees, continuing education, bookkeeping, and the annualized cost of initial setup (credentialing fees, licensing, furniture, equipment). A 2024 survey by Therapy Brands found that the median private practice therapist grosses $85,000-$95,000 annually but reports overhead costs 40% higher than initially projected. The break-even analysis is not just about covering bills -- it is about knowing exactly how many sessions per month must be billed and collected before the practice is profitable. A solo therapist with $3,200/month overhead who charges $110/session must bill and collect 30 sessions/month before the first dollar of personal income. That is a full caseload at 7.5 sessions/week, which takes 3 to 6 months to build from scratch.
What This Calculator Does
This calculator computes private practice overhead, monthly break-even session count, minimum billable rate at a target session volume, and time-to-break-even during practice ramp-up. Inputs include all overhead categories (rent, EHR, insurance, phone, supervision, CPE, billing software, bookkeeping, marketing), session fee, projected monthly session growth rate, and starting client count. Output includes monthly overhead total, break-even sessions, annual income projection at full capacity, and a month-by-month ramp-up model.
The Formula
Break-even is the session count at which total session revenue exactly equals total monthly overhead -- the point where the practice stops losing money but before the therapist earns personal income. To calculate income, add the therapist's desired personal income to the overhead total: the combined figure divided by the session fee gives the required session count to hit that income target. The ramp-up model applies a weekly or monthly session growth rate to project when the break-even and income targets will be reached from a starting point of zero clients.
Step-by-Step Example
Tally all overhead categories
Fixed monthly overhead: office rent $650, EHR/scheduling $75, telehealth platform $40, liability insurance $55 ($660/year), phone/secure messaging $45, HIPAA compliance tool $30, supervision $200, bookkeeping $75. Variable monthly: marketing $100, CPE annualized $50, credentialing software $25, bank fees $15. Total monthly overhead: $1,360. Do not include the therapist's own salary in overhead -- that is income, calculated separately.
Calculate break-even sessions
Session fee: $130. Monthly break-even: $1,360 / $130 = 10.46. Round up to 11 sessions/month. This is the number of sessions needed before the practice stops losing money. At 11 sessions, the practice breaks even. At 12, the therapist earns $130. At 25 sessions: $130 x 25 - $1,360 = $1,890 net. At 40 sessions: $130 x 40 - $1,360 = $3,840 net.
Model the ramp-up timeline
Starting caseload: 0 clients. Growth rate: 3 new clients/week for first 8 weeks (realistic with active referral outreach), then 1-2 per week to fill. Week 1-2: 2-4 clients/week. Week 8: 20+ sessions/month. Break-even (11 sessions/month) reached at approximately week 4-5. Target income ($5,000/month net = 50 sessions/month) requires full caseload: approximately month 3-4.
Identify income target session requirement
Target net income: $5,500/month. Required sessions: ($5,500 + $1,360) / $130 = 52.8 sessions/month = approximately 13.2 sessions/week. This is the steady-state target. At 50 sessions/month (12.5/week): net = $130 x 50 - $1,360 = $5,140. At 55 sessions (13.75/week): net = $5,790. Define the income target clearly -- it drives session volume and fee decisions.
Real-World Use Cases
Therapist Evaluating Office vs. Home Office vs. Telehealth-Only Setup
Comparison: physical office ($650 rent) vs. home office (no rent but $120 soundproofing/privacy cost) vs. telehealth-only ($0 rent, $40 telehealth platform). Physical office overhead: $1,360/month, break-even 11 sessions. Home office: $830/month, break-even 7 sessions. Telehealth-only: $780/month, break-even 7 sessions. Telehealth-only reaches income target at 50 sessions ($4,720 net) -- comparable to physical office with 6 fewer sessions per month required.
Group Practice Associate Cost Modeling
A group practice owner models associate profitability. Associate compensation: $65/session (50% of $130 fee). Practice overhead allocated to associate: $800/month (shared admin, office space, EHR). Break-even for the practice on this associate: ($800 + associate comp) / $130 = $800 / $65 practice margin = 13 sessions/month to cover overhead, then $65/session profit margin above that.
Established Therapist Evaluating Expansion
A solo therapist considers adding a part-time office day (renting a second office suite $350/month) to increase capacity from 22 to 30 sessions/week. Additional overhead: $350 rent + $50 additional admin. At $130/session, the 8 additional weekly sessions generate $1,040/week x 4.3 = $4,472/month. Additional overhead: $400/month. Net income increase: $4,072/month. Expansion is clearly financially justified.

Common Mistakes to Avoid
Not including supervision costs as overhead. Pre-licensed therapists pay $100-$300/month for individual and group supervision -- a mandatory expense that disappears after licensure. Failing to include it inflates the apparent profitability of early-stage practice and creates a false break-even calculation. Post-licensure, this cost is replaced (partially) by consultation fees, but the magnitude decreases substantially.
Calculating break-even on gross revenue rather than collected revenue. A therapist with a 90% collection rate who bills 50 sessions/month at $130 collects $5,850, not $6,500. Break-even must be calculated against collected revenue. Insurance billing adds a collection rate variable that reduces effective per-session revenue by 5-15% depending on payer mix and claim denial rates.
Forgetting the ramp-up period cash gap. The months between opening and reaching break-even require personal savings or income from another source. Most therapists need 2 to 4 months of working capital to cover overhead during the ramp. A $1,360/month overhead practice needs $4,000-$5,500 in cash reserves before opening -- or a second income source -- to avoid personal financial stress during client acquisition.
Frequently Asked Questions
What is the average overhead for a solo private practice therapist?
The median monthly overhead for a solo private practice therapist in 2026 is approximately $1,100 to $1,800 depending on location, office arrangement, and pre/post-licensure status. Office rent is the largest single variable: home office or shared space practices run $700-$1,000/month total, while full private office practices run $1,300-$2,200/month. Telehealth-only practices have the lowest overhead, typically $600-$900/month.
How long does it typically take a new practice to reach full caseload?
Solo private practices typically reach a full caseload (20-25 sessions/week) within 6 to 18 months, depending on referral network strength, niche specificity, and marketing investment. Therapists with established referral relationships from a prior agency or group practice position typically fill faster (3-6 months). Therapists starting with no referral network in a competitive market may take 12-18 months to reach full capacity.
Should I include my salary in the overhead calculation?
No. Overhead is the cost of running the business before owner compensation. Including your target income as an overhead item conflates two separate calculations. The correct approach: calculate break-even on overhead alone (the point where the practice covers its bills), then calculate the session count required to pay yourself at your target income on top of overhead. These are two separate numbers with different decision-making implications.
What are the tax-deductible overhead expenses for private practice?
Most private practice overhead expenses are deductible as ordinary and necessary business expenses: office rent, EHR subscriptions, professional liability insurance, continuing education, supervision, professional association memberships, phone and internet (business use portion), marketing costs, and bookkeeping fees. The home office deduction applies if a dedicated space is used exclusively for the practice. Consult a CPA familiar with mental health practice for a complete list, as rules on mixed-use expenses and depreciation vary.
