Cost per admission,
worked out by source

The monthly agency report lands on a Tuesday morning: 140 conversions. The admissions director knows nine people admitted, but not which ad, listing or partner sent each one. When callers were asked where they found the center, most said “Google” or “a friend.” The owner still has to set next month's budget.

The number that settles it is the price of each admit: what you spent on one source, divided by the people that source brought in. This post works it out source by source, shows why the per-lead price in an agency report misleads, and gives you a way to judge your own figure.

The sum

Cost per admit = spend on one source in a month ÷ admits from that source that month.

Say Google Ads cost $9,000 in October with the management fee counted, and six people admitted after calling or filling in a form from those ads. That's $1,500 an admit. Do the division for every source on its own. A single figure for all marketing hides which source is working and which isn't.

Why the per-lead price misleads

An ad report's “lead” is any call or form that Google or Meta counted. One ad buyer on Reddit put rehab costs at “$80 a lead of fb and a bit more on Google.” A low price per inquiry can still produce a costly admit. A form from out of state, a caller asking for care you don't provide, a job seeker and a second call from the same parent all count. Only the admit tells you someone came into care.

Compare two sources over one month:

By inquiries, A looks like the bargain and B gets cut. By admits, B brings people in at half the price.

A worked month, source by source

These numbers are an example, not a benchmark. Lay out your own month this way and the ranking of your sources may look nothing like your agency's.

What goes in the spend column

Count everything you pay to keep each source going:

• Ad spend, from each ad account's own billing page
• The management fee for that channel, whoever runs it
• Call tracking numbers, split across the sources they serve
• For referral partners: the BD rep's salary and benefits, mileage and event costs
• For the website: hosting, the build spread over its life, and content work

Leave the admissions team's wages out if they answer every source alike, or add them as one shared line for a fuller picture. Either way, count the same things every month, or the trend means nothing.

Which people count as admits

Count a person once they're admitted, not when the admit is booked. Use the admit date to place them in a month, and give each person one source. Most centers credit the first contact: the tracking number they rang or the form they sent. When one person came in through two sources, pick a rule once and stick to it.

A step-down from your own detox into residential is one admit, not two. Someone who comes back months later is a new admit, credited to whatever brought in that newer inquiry.

Knowing which source sent each admit

Asking callers where they found you gets “Google” or “my friend.” That can't split Google Ads from Google Maps or your own site. Give every ad, listing and partner a separate tracking number, and save the source with every form. Phone calls carry most of the volume: one Reddit ad buyer running rehab campaigns saw only “about 10-15 form fills a month,” with the rest by phone, so web analytics alone misses most inquiries. A number pool that shows each visitor a different number on your site carries the search keyword onto each call.

Then confirm the source when a coordinator opens the inquiry, and check it again at admit.

Ad conversions are not admits

Google Ads counts a call as a conversion once it passes a length you set, 60 seconds unless you change it. Meta counts form fills. Neither one knows who admitted, and neither should. Sending admit records back to an ad account hands health information to an outside company. HIPAA and the federal Part 2 rule both apply here, so ask counsel to look over any conversion setup before inquiry data leaves your systems.

Do the division on your side instead: your own admit list against the spend shown in each ad account.

Referral partners: count admits, never pay per referral

Partners don't come with a spend line. Most centers count admits per partner, then work out one figure for outreach overall: the BD program's total cost divided by every partner admit.

Never pay a partner anything for a referral. EKRA (section 220 of Title 18) and the state brokering laws forbid it. EKRA reaches staff pay too: its exception for employees doesn't cover pay that rises or falls with how many people get referred. If any part of your BD rep's pay moves with admits, get counsel to check the plan. Our post on brokering laws goes further.

What a good number looks like

There's no public benchmark worth trusting. The figures online come mostly from agencies that sell ads, measured in ways you can't check, and they blend levels of care which cost very different amounts to market. A detox admit from Google search and an IOP admit from a therapist are not alike.

Judge your own number on three tests:

• It's lower than the same source three months ago.
• It's lower than your other paid sources, or you know why it isn't, such as a program you're building.
• Your finance lead says the center can carry it.

Mind the lag as well. A click in late September can become an October admit. Read each source over a rolling 90 days, so one quiet week doesn't move budget.

A monthly review in five steps

1. Pull spend for each source from the ad accounts and your invoices.
2. Pull admits for each source from your admissions list, by admit date.
3. Divide, then put this month beside the three before it.
4. Where a number jumps, look at the steps behind it: inquiries, assessments, admits.
5. Move budget only after two straight months agree.

Take the table to the monthly owner meeting. Most months the answer isn't more spend. It's a source that stopped sending admits, or a step where inquiries stall, and our post on the five places to look covers those.

Where RehabSignal fits

RehabSignal's reporting gives US addiction treatment centers what every admit cost, split by ad and source. Ad spend is read from your Meta, Google and Microsoft accounts, and admits come from the board your admissions team works. Referral partners show admits per partner. A flat monthly fee, never priced per lead, per call or per admit.
