At $25,000 in monthly ad spend, that's a $2,778 cost per admission. Is that good? Bad? It depends on your facility type, payer mix, and what you're collecting per patient.
Why CPA Matters More Than CPL
Cost per lead (CPL) is the metric most agencies report because it makes them look good. Getting leads for $200 each sounds reasonable. But if only 10% of those leads admit, your actual cost per admission is $2,000 — and that's the number that determines whether your marketing is profitable.
CPA = Total Marketing Spend ÷ Number of Admissions
A practice spending $30,000/month on marketing and admitting 12 patients has a CPA of $2,500. If average revenue per admission is $35,000, that's a 14:1 return. Healthy. But if revenue is only $8,000 (outpatient), that same CPA is barely breaking even.
Industry Benchmarks by Facility Type
| Facility Type | Avg CPA | Top 25% | Avg Revenue/Patient |
|---|---|---|---|
| Residential (30-day) | $2,000-$5,000 | $800-$1,500 | $25,000-$50,000 |
| Detox (5-7 day) | $800-$2,500 | $500-$1,000 | $8,000-$15,000 |
| PHP | $1,000-$3,000 | $600-$1,200 | $15,000-$30,000 |
| IOP | $500-$2,000 | $300-$800 | $5,000-$15,000 |
If your CPA exceeds 15-20% of average collected revenue per patient, your marketing economics are unsustainable. The sweet spot is 5-10%.
The Funnel: Where Leads Die
Every rehab marketing funnel has four stages. Understanding conversion rates at each stage reveals where your money is actually being lost.
| Stage | Average Rate | Top Performers |
|---|---|---|
| Lead → Call Answered | 70-78% | 90%+ |
| Call → VOB Completed | 40-55% | 65%+ |
| VOB → Admission | 30-45% | 55%+ |
| Overall: Lead → Admission | 8-15% | 20-30% |
Call Answer Rate: The #1 Lever
Here's a counterintuitive truth: improving your call answer rate from 75% to 90% can reduce your CPA by 30% — without spending a single extra dollar on ads.
The math is simple. 100 leads at 75% answer rate = 75 conversations. At 90% = 90 conversations. With the same downstream conversion rates, that's 15 additional admissions per month from leads you already paid for.
Top facilities answer calls within 30 seconds, 24/7. They use dedicated intake teams (not front desk staff), call tracking to identify marketing leads, and immediate call-back systems for missed calls. The investment in a 24/7 call center ($3,000-$8,000/month) pays for itself many times over.
Channel Comparison
| Channel | Avg CPL | Lead Quality | Best For |
|---|---|---|---|
| Google Ads (Search) | $150-$400 | High | Immediate intent, high volume |
| Google Ads (Call-only) | $100-$250 | Very High | Phone-based admissions |
| SEO / Organic | $30-$100 | High | Long-term, compounding ROI |
| Facebook/Instagram | $30-$80 | Medium | Family members, awareness |
| Referral Networks | $50-$150 | Very High | Pre-qualified, warm leads |
| Lead Aggregators | $200-$500 | Low-Medium | Volume (but shared leads) |
Google Ads is the most expensive channel but also the highest intent — someone searching "drug rehab near me" at 2am is ready to act. SEO delivers the best long-term economics but takes 6-12 months to compound. The smartest facilities invest 60-70% in Google Ads for immediate admissions and 20-30% in SEO for future leverage.
The LegitScript Factor
Since 2018, Google requires LegitScript certification to run addiction treatment ads. Certification costs $950/year plus ~$2,000 in compliance preparation. This barrier actually helps established facilities — it reduces competition from fly-by-night operators and keeps CPCs from spiraling even higher. If you're not LegitScript certified, you're locked out of Google Ads entirely.
Red Flags: When Your Agency Is Overcharging
- They report CPL but refuse to share CPA data
- Your call tracking shows leads going to voicemail during business hours
- They manage both ads AND the call center (conflict of interest)
- CPL is great but admissions haven't increased
- They can't explain the 3x difference between your CPL and CPA
- Long-term contract with no performance benchmarks
