Model your sessions per day against your real collection rate, no-show losses, and overhead — and see the monthly net your speech therapy practice actually keeps after the billing reality hits.
Your scheduler shows a full week — eight kids a day, every slot booked, $180 a session. On paper that's a $28,000 month and you let yourself relax a little. Then the deposits trickle in: an insurer paid 65 cents on the billed dollar, two Tuesday families no-showed, and the billing service skimmed its eight percent. The $28,000 you mentally banked lands as a $16,500 deposit, and the gap is the part of running a practice nobody trains you for. This calculator runs the same collection, no-show, and overhead adjustments on your specific numbers so you know what actually clears the bank.
Enter your Sessions Per Day and Working Days Per Month, your Average Revenue Per Session, your Collections Rate, your insurance versus cash split, and your No-Show Rate. The model adjusts gross revenue for each of those factors before subtracting Monthly Overhead and factoring in new patient acquisition cost against new patients per month. The output is your realistic net — the number your practice actually runs on.
Why collections rate and no-show rate are where the money disappears
A speech therapist seeing 8 patients per day at $180 per session over 22 days has $31,680 in gross scheduled revenue. A 72% collection rate drops that to $22,810. A 10% no-show rate on scheduled appointments reduces it further — roughly $3,168 in lost revenue from sessions that never happened. Those two adjustments alone take $28,000-month expectations down to the $19,000–$22,000 range before a single overhead dollar is subtracted.
The calculator applies Collections Rate (%) first, then No-Show Rate (%) to the adjusted figure. You can see each adjustment in the results so the gap between scheduled revenue and collected revenue is explicit. If your collection rate is running low, the model tells you what a 5-point improvement in billing efficiency would add to monthly net — often worth $1,000–$2,000/month on its own.
Insurance versus cash pay: how the split affects your billing complexity
The Insurance vs Cash Split field captures what percentage of your sessions are private-pay versus insurance-billed. Cash-pay sessions collect 100% of the stated rate with no reimbursement lag. Insurance sessions typically collect 60–80% of your stated rate after contracted fee schedules, copays, deductibles, and claims processing. A practice that is 80% insurance-dependent has very different billing dynamics than one that is 50% cash-pay.
Shifting more sessions toward private pay or cash-pay packages typically improves collection rates and reduces administrative overhead. The calculator lets you test what happens to net revenue if you move that split — say from 80% insurance to 60% insurance — by adjusting the input. For many practices, a 20-point shift toward cash pay combined with modest session pricing increases nets more than a straight rate increase.
What it actually costs to keep your schedule full
The New Patient Acquisition Cost and New Patients Per Month inputs add a dimension most practice calculators skip. If you are spending $300 per new patient on marketing, physician referral programs, and insurance directory optimization, and you onboard 8 new patients per month, acquisition cost is $2,400/month. That $2,400 belongs in your margin calculation because it is the cost of sustaining your patient flow.
Over a full year, 8 new patients per month is 96 new patients. If each patient averages 18 sessions at $130 collected before discharge or gap in care, that is $12,480 per patient — a patient lifetime value that makes $300 acquisition cost look very manageable. The tool does not compute LTV automatically, but holding both numbers in your head while reviewing net profit puts marketing spend in its proper context.
Overhead benchmarks for a speech therapy practice
Monthly overhead in a speech therapy practice typically includes: clinic rent or therapy room lease ($800–$3,500 depending on market and whether shared), billing service fees (6–10% of collected revenue if outsourced), liability insurance ($100–$250/month), EMR/documentation software ($60–$150/month), materials and therapy supplies ($200–$500/month), and ASHA membership dues amortized monthly. A solo practitioner in a shared office suite can run monthly overhead as low as $1,500–$2,500. A dedicated office with contracted billing adds up to $4,500–$7,000.
Enter your real overhead in the Monthly Overhead field. If you outsource billing, include the billing service fee — many practices pay 7–8% of collected revenue, which on $22,000 collected is $1,540–$1,760 per month. Leaving this out produces a misleading net that will not match your actual P&L.
Working backward from the income you actually need
Many speech therapists set their daily session count based on schedule capacity, not on what the revenue model requires to hit a target net income. Work backwards instead. Enter your target monthly net income, your overhead, your collection rate and no-show assumptions, and solve for the Sessions Per Day that achieves it. A $9,000/month net target at 72% collection, 10% no-show, and $2,800 overhead requires roughly $17,000 in collected revenue — which at $130 collected per session is approximately 131 sessions per month, or 6 per working day over 22 days.
If 6 sessions per day is sustainable and 8 is not, the model tells you to either raise rates, improve collection, or reduce overhead before piling on more sessions. That is the kind of informed decision that protects longevity in a practice. Run your real numbers here — no card required, no spreadsheet setup, just the inputs your practice already knows.
How to use it
- Enter Sessions Per Day and Working Days Per Month — use your real average, not your scheduled capacity.
- Set Average Revenue Per Session ($) at your stated rate and Collections Rate (%) based on actual historical collections, not billed rate.
- Enter the percentage of sessions that are cash-pay in the Insurance vs Cash Split field and your realistic No-Show Rate (%).
- Fill in Monthly Overhead ($), New Patient Acquisition Cost ($), and New Patients Per Month.
- Read gross revenue, collected revenue after adjustments, and net profit in the results panel.
Who it's for
- Solo practitioner setting rate for a new practice — 7 sessions per day at $175, 20 working days, 68% collection rate, 8% no-show, $3,200 overhead. Net comes to $11,640/month — above her target but contingent on filling 7 slots per day. The model confirms she can hit her number at 6 sessions per day if collection improves to 78%.
- Group practice owner evaluating a new therapist hire — Adding a staff therapist who generates $22,000 gross at 74% collection and costs $6,200/month in salary plus benefits. Net contribution to the practice is positive at $10,080 per month before overhead allocation — the numbers support the hire if the therapist maintains that patient load.
- Practice owner considering cash-pay transition — Currently 85% insurance at 69% collection rate, 7% no-show. Modeling 50% cash-pay at 97% collection shows $2,900 more per month in net on the same session volume — validating the effort to market cash-pay packages to existing and new patients.
- New graduate modeling first-year expectations — 5 sessions per day, 19 working days, $155/session billed, 65% collection (still optimizing billing), 12% no-show from a new patient list. Net comes to $7,450 — enough to service student loans on an income-driven plan while the practice ramps up.
Key terms
- Collections rate
- The percentage of billed charges that are actually paid by insurers and patients. A 75% collection rate means $0.75 is collected for every $1.00 billed.
- No-show rate
- The percentage of scheduled sessions that the patient does not attend without sufficient advance notice to fill the slot. No-shows represent direct revenue loss since the therapist's time is already committed.
- Payer mix
- The distribution of insurance types among a practice's patients — Medicare, Medicaid, commercial insurance, and self-pay. Payer mix strongly influences average reimbursement rate because each payer contracts at different fee schedules.
- New patient acquisition cost
- Total marketing and outreach spend divided by number of new patients acquired. Includes referral program costs, physician outreach, directory listings, and paid advertising.
Frequently asked questions
What collection rate should I expect with insurance billing?
Most insurance-heavy speech therapy practices collect 65–80% of billed charges, depending on their payer mix, fee schedule negotiations, and billing efficiency. Medicaid-heavy practices often see lower rates (55–70%). A billing service that specializes in SLP or pediatric therapy billing can move collection rates meaningfully — worth benchmarking annually.
How should I account for sessions that run longer than billed?
The Average Revenue Per Session should reflect collected revenue per billed unit, not session duration. If your practice bills 45-minute sessions at $175 but frequently runs 60 minutes, the billed rate is still $175 — the extra 15 minutes is an unbilled extension. This shows up as an effective rate reduction; factor it into your per-session revenue estimate.
What is a realistic no-show rate for a speech therapy practice?
Pediatric practices typically see 8–15% no-show/cancellation rates, with higher rates in Medicaid populations or practices without a cancellation fee policy. Adult practices often run 5–10%. Implementing a 24-hour cancellation policy and reminder texts can reduce no-shows by 3–5 percentage points, which at scale is meaningful monthly revenue.
Should I include my own salary in Monthly Overhead?
If you are the treating therapist and also the owner, include a market-rate salary in overhead to see the true business net. A realistic SLP owner salary of $75,000–$95,000 annually is $6,250–$7,917 per month. Without it, your net profit is overstated because it includes your own uncompensated labor.
