They are one chain, and almost every surprise at the bottom of it started with what you did at the chair. Here is how they connect, and which number to check first when one of them moves. Owners who track all 16 KPIs still get surprised by their EBITDA. That happens because they read each metric on its own. EBITDA drops, overhead is up, and it looks like a spending problem. Often nobody spent a dollar more. The practice just produced less at the chair, or got paid less for the same dentistry. This is the map of how the [16 KPIs](https://reciprocityaccounting.com/blog/dental-practice-kpis) connect, so you fix the number that actually broke instead of the one that showed the damage. ## Production sits under every percentage Almost every KPI you track is a percentage of **net production**: what you did at the chair after the PPO takes its contractual cut. Supplies, lab, staffing, hygiene, overhead and EBITDA all sit on top of it. That makes net production the most important number that is not on the list. When it moves, every percentage moves with it, even if nothing else changed. Seat fewer crowns, lose a hygiene day to cancellations, or take a fee cut from a payer, and every cost line suddenly looks worse. The dollars did not change. The denominator did. So when a cost percentage jumps, ask two questions in this order. Did net production fall? Or did the cost dollars rise? They look identical on the report and they have opposite fixes. [Production vs. collections](https://reciprocityaccounting.com/blog/production-vs-collections-dental-practice) walks through the difference in detail. ## Revenue metrics tell you about cash, not the ratios [Collection ratio](https://reciprocityaccounting.com/blog/dental-practice-collection-ratio) and [AR over 90 days](https://reciprocityaccounting.com/blog/dental-accounts-receivable-aging) answer a different question: is the dentistry you did turning into money in the bank? Collection ratio is collections divided by net production. A healthy practice runs 98% to 100%. When it slips, you did the work and did not get paid for it. That hurts cash right away. It does not change your cost percentages, because those are measured against net production, which the slip never touched. Where it does reach profit is later. A claim that sits past 90 days has a real chance of never being paid. Once it gets written off as [bad debt](https://reciprocityaccounting.com/blog/dental-practice-bad-debt), it finally shows up on the P&L. AR over 90 days is the early warning. Keep it under 10% of total AR and you catch the problem while it is still cash, not a loss. ## Cost metrics build overhead Supplies, lab, staffing and hygiene labor are the pieces total overhead is made of. Clinical costs run [10% to 14% combined](https://reciprocityaccounting.com/blog/dental-clinical-cost-percentage). [Staffing](https://reciprocityaccounting.com/blog/dental-practice-staffing-percentage) runs 25% to 30%. Together they account for most of [total overhead's](https://reciprocityaccounting.com/blog/dental-practice-overhead-percentage) 55% to 65% range. That is not a coincidence. Overhead is built from these lines, not measured separately. When overhead creeps up and nobody can say why, the answer is almost never "overhead." It is one line inside it that moved. Check the dollars first. If supply, lab and payroll dollars are flat and the percentages still rose, go back up the chain to net production. ## Operational metrics loop back into production This is the one loop in the chain, and it runs backward. [Hygiene production](https://reciprocityaccounting.com/blog/dental-hygiene-production-percentage) and the [hygiene productivity ratio](https://reciprocityaccounting.com/blog/dental-hygiene-productivity-ratio) do not just describe the hygiene department. They feed the production number everything else sits on. Every open hygiene hour is a cleaning not done, an exam not done, and treatment not diagnosed. That is production your own chair never sees. Hygiene running well under 30% of net production usually means open time in the hygiene schedule. Every $1 of fully loaded hygienist cost should return $3.00 to $3.50 of production. When it does not, net production drops, and every cost percentage in the chain rises with it. [Occupancy](https://reciprocityaccounting.com/blog/dental-practice-rent-occupancy-percentage) and [marketing spend](https://reciprocityaccounting.com/blog/dental-practice-marketing-spend) are costs, so they feed overhead like any other line. What they lack is a published benchmark. Rent is set by your lease and your market, and marketing by how hard you are trying to grow. Track both against your own trend, not a target that does not exist. ## Profitability is the output Adjusted EBITDA and SDE are not a separate thing to manage. They are the result of everything above them: net production, minus costs, then either a fair wage for the dentistry (EBITDA) or not (SDE). A solo owner-operator's 15% to 18% adjusted EBITDA and a multi-provider group's 18% to 25% or more are what is left once production and costs have already happened. [The EBITDA post](https://reciprocityaccounting.com/blog/dental-practice-ebitda) covers the difference between the two. That is why chasing an EBITDA number directly rarely works. There is nothing to pull on at that level. Every real lever sits upstream, in what you produce, what it costs, and how full the schedule is. ## The visual: how they connect The chain runs left to right, with one loop worth knowing about. | **Revenue** Collection Ratio AR \>90 Days % | › | **Cost** Supply, Lab, Clinical Staffing, Hygiene Labor | › | **Operational** Hygiene Production % Hygiene Productivity Ratio | › | **Profitability** Total Overhead % Adjusted EBITDA / SDE | | --- | --- | --- | --- | --- | --- | --- | | A slip in **Collection Ratio** is a cash problem first. It shows up as a rising **AR \>90 Days %** and only reaches profit when an old claim is written off. Rising **Cost** dollars feed straight into **Total Overhead %**. Everything nets out in **Adjusted EBITDA / SDE**, the one number you cannot manage directly, because it is only ever a result. | | | | | | | | **The loop:** a weak **Hygiene Production %** shrinks net production, the number under every percentage. Fill the hygiene schedule and the Cost and Profitability columns improve without cutting a dollar. | | | | | | | When something moves, do not start at EBITDA. Start at net production, then check cost dollars, then the hygiene schedule. Collections tells you about cash. It will not explain a ratio. Take a practice where adjusted EBITDA slides from 19% to 15% over two quarters and nothing about spending changed. Total overhead rose from 58% to 62%, which looks like a cost problem. Supply, lab and payroll dollars were flat. Collection ratio held at 99%. The practice collected everything it was owed. What moved was net production. A payer repriced two plans, so the same crowns and cleanings at the chair produced less. The same payroll dollars, divided by a smaller production number, became a bigger percentage on every line. Nothing about cost discipline changed. The fix was in [payer mix](https://reciprocityaccounting.com/blog/dental-practice-payer-mix) and fee schedules, three columns upstream of where the damage showed. *P.S.* [*Reciprocity Accounting*](https://reciprocityaccounting.com) *tracks all 16 of these against each other every month, not just against a benchmark chart, so you see the chain before it costs you a quarter.* [*See how we can help your practice.*](https://reciprocityaccounting.com/contact) ## Frequently Asked Questions ### Which KPI should I check first if something looks off? Start with net production, the number almost every other KPI is a percentage of. If it fell, every cost percentage rises even when spending is flat. If it held, look at cost dollars next. Collection ratio is where you look when cash is short, not when a ratio moves. ### Why did my EBITDA drop when my costs did not change? Because EBITDA and every cost percentage are measured against net production. If you produced less, or a payer cut what it pays for the same procedures, the same cost dollars become a bigger share and EBITDA shrinks. Check net production and payer mix before assuming a cost problem. ### Does a low collection ratio make my overhead look worse? No. Overhead and the other cost percentages are measured against net production, and collections do not change net production. A low collection ratio hurts cash first. It reaches profit only when old claims are written off as bad debt. ### How does hygiene affect profitability if hygiene is not in the profitability family? Hygiene feeds production. Open hygiene time means fewer cleanings, fewer exams and less diagnosed treatment, so net production falls. Every cost percentage rises with it, and EBITDA shrinks, even though nothing in hygiene shows up as a labeled cause. ### Where do occupancy and marketing spend fit in the chain? They are costs, so they feed total overhead like any other line. Neither has a published benchmark, so track both against your own trend and your own commitments, such as lease terms and new-patient counts, rather than a target range that does not exist. ### Do I need to memorize all 16 formulas to use this chain? No. Know which family a metric belongs to and what it is measured against. Most of them sit on net production, so when a ratio moves, ask first whether production changed. The formulas matter less than knowing where to look. ## Share this post [mailto:https%3A%2F%2Freciprocityaccounting.com%2Fblog%2Fdental-kpis-visual-guide](mailto:https%3A%2F%2Freciprocityaccounting.com%2Fblog%2Fdental-kpis-visual-guide) ## Keep reading ### [![Reciprocity Accounting card: Dental Practice Accounting, a How To post.](https://reciprocityaccounting.com/hs-fs/hubfs/blog-images/post_60.png?width=1200&height=630&name=post_60.png) How To Dental Practice Accounting: A Complete Guide for Owner-Operators](https://reciprocityaccounting.com/blog/dental-practice-accounting-guide) ### [![Reciprocity Accounting card: Building a Monthly Financial Review, a How To post.](https://reciprocityaccounting.com/hs-fs/hubfs/blog-images/post_59.png?width=1200&height=630&name=post_59.png) How To How to Build a Monthly Financial Review Process for Your Dental Practice](https://reciprocityaccounting.com/blog/build-monthly-financial-review-process-dental) | ![Reciprocity Accounting](https://reciprocityaccounting.com/hubfs/logo_horizontal_dark_transparent.png) Accounting built for dental practices.
