Model your optometry practice revenue using actual patient volume, exam fees, optical revenue, collections rate, and overhead — not a textbook average.
Your VSP contract pays $62 for a comprehensive exam. Your cash-pay patient pays whatever rate you set. Optical fills in the gap — but only if your capture rate and frame margin are doing their job. Exam fees are insurance-driven with a collections rate that rarely reaches 100%; optical frame and lens sales are retail transactions with a markup margin you control. This calculator models the clinical side by taking Patients Per Day, Working Days Per Month, and Average Revenue Per Patient, adjusted by Collections Rate, Insurance vs Cash Split, and No-Show Rate.
The tool defaults reflect a mid-size general optometry practice: 18 patients per day over 22 working days at $185 per patient, with a 92% collections rate and 10% no-show rate. Against $18,500 in monthly overhead, that produces a net monthly revenue figure. Change any input and watch the result shift in real time. A practice seeing 22 patients per day versus 14 has a dramatically different revenue picture even at identical rates — and the overhead does not change between the two scenarios.
Exam revenue versus optical revenue: two different margin profiles
Insurance-reimbursed comprehensive eye exams generate revenue on a fixed fee schedule that you cannot price above your contracted rate. A VSP contract might pay $50–$65 for a comprehensive exam; EyeMed might pay $60–$75. Medical eye exams for conditions like glaucoma or diabetic eye disease typically reimburse at a higher rate through medical insurance. Your Average Revenue Per Patient in the calculator blends all of these.
Optical dispensary revenue — glasses frames, lenses, contact lenses — is retail with a markup you control. Frame and lens packages with typical mark-up practices run 2.5–3.5 times cost. A frame that costs $40 wholesale is priced at $100–$140 retail. Contact lens margins are tighter due to online competition, but remain significant on in-office inventory. Including optical in your revenue model requires a separate entry, or you can fold it into the average per-patient figure by including optical capture rate and average dispensary spend.
Collections rate and payer mix dynamics
A 92% collections rate in optometry is solid but not uncommon for practices with well-managed billing. The remaining 8% reflects vision insurance adjustment write-downs (the difference between your fee and the contracted rate), copay write-offs, and claim denials. The contracted write-down component is structural — it is the cost of being in-network with a payer — and differs from actual bad debt or billing errors.
If your collections rate drops below 88%, the most common culprits are: billing delays beyond 7 days of service, expired insurance credentialing, vision plan patients being billed under medical insurance (or vice versa), and frame and lens claims submitted without proper dispensing documentation. The calculator's Collections Rate slider shows you what each percentage point is worth. At 18 patients per day and $185 average, moving from 88% to 93% collections adds roughly $3,388 per month.
No-show rates in optometry: lower than most specialties, still costly
Optometry no-show rates tend to run 5–12%, lower than behavioral health but not negligible. At 18 patients per day over 22 days, a 10% no-show rate means roughly 36 missed appointments per month. At $185 average revenue with a 92% collections rate, that is about $6,132 in unbilled service. Even reducing no-shows by half would recover approximately $3,000 per month.
The most effective interventions for optometry practices are appointment reminders 48 and 24 hours before the visit (text message reminders outperform phone calls in most studies), a clear same-day cancellation policy posted at booking, and strategic overbooking for patient types with historically higher no-show rates. The tool quantifies the monthly cost of your current no-show rate so you can weigh it against the cost of any intervention system.
What a new patient is actually worth over five years
At 18 new patients per month and $35 acquisition cost, the practice spends $630 per month to bring in new patients. The key question is return on that investment: an optometry patient who books an annual exam and purchases glasses generates roughly $250–$400 per visit in combined exam and optical revenue. Over a five-year retention period at annual visits, a patient acquired for $35 generates $1,250–$2,000 in total practice revenue.
Most optometry practices fill their new patient pipeline through a combination of in-network insurance plans (which drive referrals when patients look for in-network providers), Google Business profile management and patient reviews, and physician referrals for medical eye cases. Direct advertising spend tends to produce better results for practices in new or underserved markets than for established practices in competitive areas.
What $18,500 in monthly overhead looks like — and where to find the levers
For a mid-size optometry practice, $18,500 in monthly overhead breaks down roughly as: rent $3,500–$5,000, staff salaries (front desk, optician, optical lab tech) $9,000–$12,000, optical inventory carrying cost $1,000–$2,000, equipment lease and maintenance $800–$1,500, malpractice and general liability $400–$600, and billing software $200–$500. The single largest variable is staffing, which scales with patient volume.
Overhead as a percentage of collected revenue is the efficiency ratio that benchmarks against industry standards. Healthy optometry practices generally target overhead at 50–65% of collected revenue, which implies a net margin of 35–50%. Below 35% net margin usually means overhead is disproportionate to volume; above 55% suggests either high volume and efficiency, or a high-margin optical dispensary component that lifts total revenue above the exam-only baseline.

Who it's for
- Solo OD evaluating additional days of service — Currently seeing 18 patients 4 days per week, models adding a 5th day, and checks whether the incremental revenue from 22 extra monthly patients covers the additional staff and overhead cost.
- Practice adding a medical eye care component — Increases Average Revenue Per Patient from $160 to $195 to reflect higher-reimbursing medical exams, adjusting collections rate upward for medical insurance claims, and models the revenue lift.
- OD evaluating direct-pay membership model — Shifts the cash percentage from 30% to 60%, models a higher per-patient rate of $250 for the cash-pay segment, and compares net income against the current insurance-heavy model to evaluate a hybrid membership program.
- Partnership practice planning a second location — Runs the calculator at conservative new-location patient volume (10 patients per day) against projected overhead, identifies the breakeven patient count, and uses that as the go/no-go threshold for the lease decision.
Key terms
- Optical capture rate
- The percentage of patients who receive an exam and also purchase eyewear or contact lenses from your dispensary in the same visit. Higher capture rates materially increase revenue per patient.
- Vision insurance
- Specialized insurance plans (VSP, EyeMed, Davis Vision) that reimburse routine eye exams and help with eyewear costs. Reimbursement rates are set by contract and are often lower than medical insurance rates for comparable exam complexity.
- Medical eye exam
- An examination for a diagnosed eye condition such as glaucoma, diabetic retinopathy, or macular degeneration. Billed under medical insurance rather than vision insurance, typically at higher reimbursement rates.
- Collections write-down
- The difference between a billed fee and the contracted insurance rate, which is adjusted off the bill rather than collected. Part of the effective collections rate reduction in insurance-based practices.
Frequently asked questions
Should optical dispensary revenue be included in Average Revenue Per Patient?
Yes, if you want the model to reflect your full practice economics. Compute your actual average dispensary revenue per patient (total optical revenue divided by total patients seen) and add it to your average exam reimbursement. Alternatively, run the exam revenue calculation separately and add your optical gross margin as a flat monthly addition to net income.
What is a typical per-patient revenue for a comprehensive eye exam?
Pure exam reimbursement from vision insurance plans typically runs $50–$80 for a comprehensive exam. Medical eye exams through medical insurance can run $150–$250. A blended average including optical capture depends on optical conversion rates and package pricing but commonly falls in the $180–$300 range per patient for full-scope practices.
How does being in-network affect collections rate?
Being in-network with a vision plan means accepting a contracted rate that may be lower than your fee schedule. The difference between your full fee and the contracted rate is a write-down, not a bad debt — but it reduces your effective collections rate per billed dollar. The tool's collections rate input captures all of this in one number, whether the gap comes from write-downs or actual claim denials.
What is the right overhead percentage for an optometry practice?
Industry benchmarks suggest overhead at 55–70% of collected revenue for general optometry, leaving 30–45% as net income. Practices with high optical revenue often have lower overhead percentages because optical is higher margin per dollar. Practices with low optical capture and heavily discounted vision plan exams tend to run higher overhead ratios.
