Net production is gross production minus contractual write-offs, in other words what the practice is entitled to collect. Dividing collections by net production shows how much of that money arrives. A ratio of 98% or higher is the target most often quoted by dental consultants.
Measure it over a rolling three months, because payments lag treatment. A falling ratio points to uncollected patient portions, unworked claims or adjustments entered incorrectly.
The formula, with a worked example
Net collection ratio = total collections ÷ (gross production − adjustments) × 100. Adjustments here means contractual write-offs: the part of the fee you agreed not to charge a PPO or other plan. It does not include money you simply failed to collect.
Take a month with $100,000 of gross production and $25,000 of PPO write-offs. Net production is $75,000. If collections are $73,500, the net collection ratio is 98%. The gross collection ratio, collections divided by gross production, is 73.5%, which looks poor but mostly reflects the fee discounts you agreed to.
| Measure | Formula | Example |
|---|---|---|
| Gross production | Fees for all treatment at your full fee schedule | $100,000 |
| Net production | Gross production minus contractual write-offs | $75,000 |
| Collections | Money received from patients and insurance | $73,500 |
| Net collection ratio | Collections ÷ net production | 98% |
| Gross collection ratio | Collections ÷ gross production | 73.5% |
Why use the net figure
The gross ratio punishes a practice for taking PPO patients. The net ratio compares what you collected with what you were entitled to collect, so it measures the front desk, billing and claims follow-up rather than your fee schedule. It is the figure that tells you whether work is leaking.
What a low ratio points to
The usual causes are a small number of known problems: patient portions that are never collected at checkout, claims rejected and not reworked, unpaid balances that age without follow-up, incorrect adjustments or write-offs entered as discounts, and insurance estimates that were too optimistic.
Break the number down by payer, provider and location. One dentist, one carrier or one new employee often explains most of the gap.
Measure it properly
Payments lag treatment, so use a rolling three months rather than a single month, and compare the same period each time. Be careful when the practice changes software: some systems classify write-offs and adjustments differently, so a jump can come from a report setting and not from performance.
Many consultants cite 98% or more as a healthy target. Treat it as a guide, since your payer mix and policies affect what is achievable.

FAQ
What is a good net collection ratio for a dental practice?
The figure most often quoted by dental consultants is 98% or higher, measured over a rolling three months. A persistent figure below the mid-90s points to uncollected patient portions or unworked claims.
What is the difference between net and gross collection ratio?
The gross ratio divides collections by full-fee production, so it falls whenever you accept PPO discounts. The net ratio divides by production after contractual write-offs, which isolates how well you collect what you are owed.
Where do I find it in my software?
Practice management reports and analytics tools show collections, production and adjustments. The names differ by system, so check that its definition of adjustments matches the one above. Our KPI dashboard guide lists what to track.
