The spend comes from your books, the count comes from your practice software, and no published range can stand in for it. Your cost per new patient is your acquisition spending for a period divided by the number of new patients your practice software counted in the same period. Run it over 12 months, pull the spending from a marketing account that is coded the same way every month, and pull the count from the same report every time. The answer is a dollar figure that belongs to your practice and to no one else, and its trend tells you more than any published range could. ## Why the Published Range Is Not Evidence Search for the average dental cost per new patient and you will find a confident range. Look for where it came from and you will rarely find a sample size or a survey method. The ADA does not publish one, and neither does any government source we could find. Whatever their origin, a single range would blend practices in different markets, at different stages, counting different things. Even an honest average would not help much. A startup buying its first thousand patients and a 20-year practice that fills from referrals should have very different costs per new patient, and both can be healthy. The same is true of the broader marketing line, which our post on [dental marketing spend](https://reciprocityaccounting.com/blog/dental-practice-marketing-spend) shows has no sourced benchmark either. What you can know precisely is your own number, because you hold both halves of it. ## What Counts as Acquisition Cost and What Does Not The numerator is money spent to bring in patients who have never been to the practice. Money spent on patients you already have is retention, and mixing the two inflates the cost of a new patient while hiding what recall is costing you. | Count it | Leave it out | | --- | --- | | Paid search, social and display ads | Recall postcards, texts and reactivation campaigns to existing patients | | Agency and SEO fees for new patient campaigns | Website hosting you would pay with or without campaigns, unless you decide to count it every month (it can stay in the marketing account either way) | | Direct mail to new households | Community donations with no advertising return | | Referral thank-you gifts | Staff apparel | | New patient offers you pay for, such as a printed coupon run | The discount itself, which comes off production as a patient adjustment rather than adding an expense | Referral gifts are business gifts, and the IRS limits the deduction to $25 per person per year ([IRS Publication 463](https://www.irs.gov/publications/p463)). They still belong in your acquisition cost at their full amount, because that is what you spent. A marketing coordinator's wages are the biggest judgment call. On the books they stay in payroll. For your own management number you can add them in, but if you do, say so and do it every month. If the definition changes mid-year, the months before and after the change cannot be compared. ## Mapping It in Your Chart of Accounts One way to set it up is to give marketing its own section of the P&L with a subaccount for each channel you use, and keep acquisition separate from retention. For example: paid search, social, direct mail, agency fees, referral gifts, and a separate line for recall and reactivation. Our [dental chart of accounts template](https://reciprocityaccounting.com/blog/dental-chart-of-accounts-template) puts marketing in one group, 7500, and channel lines can sit as subaccounts beneath it. Setting it up is free. Splitting a year of lumped charges afterward is not, because nobody remembers in March what a charge in July was for. Lumping everything into one account is the same kind of problem as the coding errors in our post on [common bookkeeping mistakes](https://reciprocityaccounting.com/blog/dental-practice-bookkeeping-mistakes): it leaves you with a total you cannot take apart. ## Getting the New Patient Count From the Right Place The denominator comes from your practice software, and practice software systems do not agree on what a new patient is. Open Dental's New Patients report "lists all new patients whose first completed procedure falls within a specific date range," and the manual adds that this "is not related to the patient's date of first visit" ([Open Dental manual](https://opendental.com/manual/reportsnewpatient.html)). Henry Schein One's 2019 reports reference for Dentrix Enterprise describes a New Patient List that "displays patients whose first visit date falls within a selected date range" ([Dentrix Enterprise 11.0 Reports Reference](https://www.ihs.gov/doh/edr/documents/Dentrix_Enterprise_11.0_Reports_Reference.pdf)). A patient whose first visit was in June but whose first procedure was completed in July lands in different months depending on which report you use. Check how your own version defines it. Either definition works, as long as you never switch. Pick one report, write down which one, and pull it the same way every month. Count by source from that same report. Open Dental's New Patients report shows each patient's first Referral From entry from the Family Module, so your channel counts use the same definition as your total. A front desk that skips that field leaves those patients with no source, and every channel looks more expensive than it really is. ## Computing It Monthly and Reading the Trend Use a trailing 12 months for both halves, updated each month. A single month is too noisy, because a campaign paid for in March may bring patients in through June. | Trailing 12 months | Spend | New patients | Cost per new patient | | --- | --- | --- | --- | | Whole practice | $45,000 | 250 | $180 | | Paid search | $18,000 | 60 | $300 | | Direct mail | $9,000 | 15 | $600 | | Referral gifts | $1,500 | 90 | $17 | These numbers are illustrative. The blended number looks reasonable. The channel numbers show that direct mail costs twice what paid search does for each patient, and that referrals cost almost nothing. The channel rows will not add up to the total, because some new patients come with no recorded source and some spending supports more than one channel. That is fine, as long as the gap stays roughly the same size from month to month. The direction matters more than the level. If spending grows and the cost per new patient holds, the added spending is buying patients at the old price. If it climbs, you are paying more for each one. Put it next to what those patients produce: Open Dental's New Patients report includes each patient's production, though the manual notes it is "total gross production for all time," not the first visit or the reporting period, so read it as gross and allow for time. ## What a Believable Number Looks Like Whether your number is believable depends on how it was built, not on how it compares with anyone else's. The spend total should tie to the acquisition lines in the marketing section of your P&L for the same 12 months. Anything you add from outside that section, such as coordinator wages, or leave out of it, such as hosting, should be listed and the same every month. The new patient count should tie to the report you named, run the same way. The definition of what counts should be written down and unchanged. And every big move should have an explanation you can point to, such as a campaign that started or a channel that stopped. That is the number to bring to your next budget conversation with whoever runs your marketing. *P.S.* [*Reciprocity Accounting*](https://reciprocityaccounting.com) *keeps marketing coded the same way every month, so the spend half of your cost per new patient comes straight from your books.* [*See how we can help your practice.*](https://reciprocityaccounting.com/contact) ## Frequently Asked Questions ### What is a good cost per new patient for a dental practice? There is no sourced benchmark. The ranges that circulate rarely come with a sample size or method. Compute your own over a trailing 12 months and judge it by its trend and by what those patients go on to produce. ### How do I calculate cost per new patient? Add up what you spent to attract new patients over 12 months, then divide by the new patients your practice software counted over the same 12 months, using the same report every time. ### Should recall and reactivation costs count? No. Those are spent on patients you already have. Track them separately as retention so they do not inflate the cost of a new patient. ### Why does my new patient count differ between reports? Systems define a new patient differently. Open Dental's New Patients report counts by first completed procedure, while Dentrix Enterprise's New Patient List counts by first visit date. Pick one report and use it every month. ### Should I include my marketing coordinator's salary? On the books, no, it stays in payroll. In your own management number you can include it, as long as you say so and do it the same way every month. **Related reading:** - [Why Your Dental Practice Needs a Standardized COA](https://reciprocityaccounting.com/blog/dental-practice-standardized-chart-of-accounts) - [Open Dental vs. Dentrix vs. Eaglesoft: What Matters for Your Books](https://reciprocityaccounting.com/blog/open-dental-vs-dentrix-vs-eaglesoft-bookkeeping) - [The 16 KPIs Every Dental Practice Owner Should Track](https://reciprocityaccounting.com/blog/dental-practice-kpis) ## Share this post [mailto:https%3A%2F%2Freciprocityaccounting.com%2Fblog%2Fdental-cost-per-new-patient-from-your-books](mailto:https%3A%2F%2Freciprocityaccounting.com%2Fblog%2Fdental-cost-per-new-patient-from-your-books) ## Keep reading ### [![Reciprocity Accounting card: Marketing at 5%: Spend or Volume?, a Problems post.](https://reciprocityaccounting.com/hs-fs/hubfs/blog-images/post_224.png?width=1200&height=630&name=post_224.png) Problems Dental Marketing at 5%: Spend Problem or Volume Problem?](https://reciprocityaccounting.com/blog/dental-marketing-spend-volume-problem) ### [![Reciprocity Accounting card: What an Empty Chair Costs per Hour, a Cost post.](https://reciprocityaccounting.com/hs-fs/hubfs/blog-images/post_223.png?width=1200&height=630&name=post_223.png) Cost What an Empty Dental Chair Costs You per Hour](https://reciprocityaccounting.com/blog/dental-empty-chair-cost-per-hour) | ![Reciprocity Accounting](https://reciprocityaccounting.com/hubfs/logo_horizontal_dark_transparent.png) Accounting built for dental practices.
