Project your orthodontic practice revenue using real case volume, case fees, collections efficiency, and the cost to acquire new patients — not a national benchmark.
You can start three new $5,500 cases in a week and still have a slow month at the bank. Ortho money does not arrive when a case starts — it trickles in over 18 to 30 months of installments, which means your real monthly revenue is driven by how many active cases are paying right now, not how many you just signed. That one fact trips up owners who budget off new starts. This calculator works the way the money actually moves: Cases Per Day, Working Days Per Month, and Average Revenue Per Case, run through your Collections Rate, Insurance vs Cash Split, and No-Show Rate to land on collected monthly revenue.
The $32,000 monthly overhead default in the tool reflects the cost structure of a mid-size standalone orthodontic office: orthodontist compensation, two or three clinical chairs, front desk and coordination staff, and the technology infrastructure specific to ortho (CBCT imaging, iTero scanner, digital treatment planning). Enter your actual overhead and the model reflects your real practice rather than a benchmark.
Case fee economics: where orthodontic revenue comes from
Unlike most healthcare practices where revenue per visit is $50–$200, a single orthodontic case generates $3,500–$8,000 depending on complexity, market, and appliance type. Traditional braces in a mid-tier market might be contracted at $4,500. Comprehensive aligner treatment can run $5,500–$7,500. Retainer-only or limited treatment cases may be $1,500–$2,500. The Average Revenue Per Case field in the calculator should reflect your blended fee across all case types — not your comprehensive braces fee alone.
At $420 per case in the tool default, that represents a simplified monthly revenue unit — but the more accurate way to model an orthodontic practice is to think of each case as generating a monthly installment. If your average comprehensive case is $5,400 paid over 24 months, each active case contributes $225 per month to collected revenue. At 12 cases per day over 22 days, your active case count grows over time, and so does the installment-based revenue stream.
Collections efficiency: the installment challenge
The 90% collections rate default reflects a practice with solid financial policy enforcement: a required down payment at contract signing, automated payment reminders, and a consistent response to delinquent accounts. Orthodontic practices that do not enforce down payments or let accounts become significantly overdue often run collections rates of 80–85%, which on a $32,000 overhead practice can mean $3,000–$5,000 per month in revenue that was contracted but never collected.
Insurance coordination in orthodontics typically involves a lifetime orthodontic benefit of $1,000–$2,500 per patient, split between the insurer and the patient balance. The Collections Rate slider already accounts for the insurance payment portion; what it does not capture is treatment abandonment, where a patient stops coming in and stops paying mid-treatment. Practices with a clear abandonment protocol — and a clear contract that specifies the remaining balance on abandonment — have structurally higher effective collections rates.
The referral economy that fills the chairs
Orthodontic practices acquire new patients primarily from three sources: general dentist referrals, internal referrals (satisfied patients sending family), and direct consumer inquiry from online presence. The $85 per new patient acquisition cost in the tool default reflects an established practice where most new patients come through referrals, which carry low marginal cost. A practice in a growth phase or a new market might spend $150–$300 per new patient through paid ads and community events.
Given that an orthodontic patient generates $3,500–$8,000 in total revenue, acquisition cost up to several hundred dollars per patient is economically defensible. The return calculation is clear: a $150 acquisition cost on a $5,400 case is a 2.8% marketing-to-revenue ratio. If paid digital campaigns generate verified starts at that cost, they are worth running. What matters is tracking which acquisition channel produces actual treatment starts, not just consultation inquiries.
No-shows in an orthodontic adjustment schedule
Orthodontic adjustment appointments are brief — 20–30 minutes — and frequent, typically every 6–8 weeks per case. A no-show for an adjustment does not generate immediate billing loss the way a dentist's missed filling appointment does, but it disrupts the treatment timeline, requires rescheduling into an already full adjustment schedule, and reduces the effective production of the chair time. At 8% no-show rate on a high-volume adjustment schedule, the downstream cost is bottlenecked throughput.
Most orthodontic practices manage no-shows through reminder text/email sequences and firm rescheduling policies. The calculator models no-shows as a revenue reduction on the case-based revenue inputs, which approximates the throughput impact. A 4% no-show rate versus 8% is roughly 13 additional productive appointment slots per month in a busy practice — the difference between a fully productive schedule and one that regularly runs light.
Reading the benchmark: healthy margins in an orthodontic office
Established solo orthodontic practices generally target overhead ratios of 60–70% of collected revenue, leaving 30–40% as doctor compensation and profit. High-volume practices with efficient scheduling and strong new patient flow sometimes reach 45–50% margin. Below 25% net margin suggests overhead is consuming too large a share, usually driven by over-staffed clinical coordination or rent in a premium location.
The tool flags the margin percentage alongside net monthly revenue. If the result comes back at 20% or below, use the overhead and patient volume inputs to identify which lever moves the number fastest: reducing overhead requires renegotiating fixed costs, which is slow. Increasing patient volume requires either longer hours or a second chair, which takes time. Raising case fees is the fastest lever and the one most ortho owners are reluctant to use without data behind them. The calculator gives you that data.
How to use it

- Enter No-Show Rate, Monthly Overhead, New Patient Acquisition Cost, and New Patients Per Month.
Who it's for
- Solo orthodontist evaluating fee schedule update — Raises Average Revenue Per Case from $4,200 to $4,800, holds all other inputs constant, and finds the monthly revenue impact before discussing fee changes with the practice manager.
- Group practice projecting associate addition — Adds Cases Per Day volume for a part-time associate, includes the associate's daily fee in overhead, and checks whether the incremental collected revenue exceeds the employment cost.
- New practice estimating time to profitability — Models conservative first-year patient volume at 6 cases per day, tests against the full overhead of a new solo practice, and identifies the months-to-breakeven.
- Practice manager analyzing collection policy results — Moves collections rate from 85% to 92% to reflect a new automated payment system's impact, and quantifies the monthly revenue difference to justify the system's implementation cost.
Key terms
- Active case
- A patient currently in orthodontic treatment who has contracted for a treatment fee and is attending regular adjustment appointments. Active case count drives the installment-based revenue stream.
- Treatment abandonment
- When a patient stops attending appointments and stops making payments before completing treatment. A key driver of collections rate reduction in orthodontic practices without clear contract enforcement.
- Limited treatment
- An orthodontic case with a narrower scope than comprehensive treatment — for example, alignment of anterior teeth only or Phase I early treatment. Typically lower in total fee and shorter in treatment duration.
- New patient conversion rate
- The percentage of orthodontic consultations that result in a signed treatment contract and initial payment. Practices typically convert 60–75% of consultations; below 50% suggests pricing, communication, or competition issues.
Frequently asked questions
Should I model orthodontic revenue per start or per adjustment visit?
The calculator uses Cases Per Day as the production unit, which most closely approximates adjustment visit volume. For a more precise model, multiply your active case count by your average monthly installment per case, and use that as your effective monthly revenue before collections adjustments. Either approach produces useful planning numbers.
What counts as a case for the purposes of this calculator?
Any contracted treatment episode: comprehensive braces, full aligner treatment, limited treatment, or a retainer-phase case. Each counts as one case regardless of the associated fee. If you see a mix of comprehensive ($5,400) and limited ($1,800) cases, your blended Average Revenue Per Case should weight toward whichever type makes up the larger share of your schedule.
What is a realistic collections rate for an orthodontic practice?
Well-run orthodontic practices with clear financial policies, required down payments, and automated payment follow-up typically collect 88–94% of contracted case revenue. Below 85% usually indicates a systemic issue in financial policy enforcement or significant treatment abandonment rates.
How does the calculator handle installment payments?
The model works at a monthly revenue level, treating Average Revenue Per Case as a per-unit figure that approximates your monthly case production value. For the most accurate orthodontic projection, use your average monthly installment per active case multiplied by your active case count as the revenue input — that gives you a more precise collected revenue figure based on your current panel. Input your actual case volume and fee schedule here — the margin percentage the model returns is the number to bring into your next fee review.
