LTV : CAC Ratio
Aggressive scaling justified. Often indicates you're underspending — capture more market share.
LTV assumes 70% year-1 retention for non-members and 18-month average tenure for members. Adjust inputs to match your actual data.
Why LTV:CAC is the metric that matters
Every other marketing metric — impressions, rankings, clicks, ad spend — is a proxy. The LTV:CAC ratio is the actual business. It tells you whether every dollar you spend on marketing returns three, five, or ten dollars in patient revenue. It’s the number that predicts whether adding budget will grow the clinic or drain it.
Most Canadian aesthetic clinic owners can quote their monthly marketing spend but can’t calculate their CAC. That gap is why scaling decisions go wrong. This tool closes it in under five minutes.
How to interpret your ratio
- Below 1:1: Unprofitable — every new patient loses money. Immediate fixes required before any more spend.
- 1:1 to 2:1: Too tight. Break-even to marginally profitable. Fix LTV (memberships, retention) before scaling.
- 2:1 to 3:1: Marginal. Sustainable but growth-limited. Optimize before adding budget.
- 3:1 to 5:1: Healthy. Scale-ready. Add spend to winning channels, monitor CAC as spend grows.
- 5:1+: Excellent. Often indicates you’re under-spending and could grab more market share aggressively.
The 4 levers that improve LTV:CAC ratio
- Launch memberships: single biggest LTV lever — 4-8× higher LTV vs one-off patients
- Improve consultation conversion: better consultation experience, deposits, pre-consult nurture
- Optimize ad targeting: tighter geo, better audiences, negative keywords all lower CAC
- Shift channel mix: shift spend from paid to compounding channels (SEO, GBP, reviews) as they mature
FAQ
What LTV:CAC ratio does an aesthetic clinic need to scale?+
A ratio of 3:1 or higher indicates healthy, scale-ready marketing. 2:1 is profitable but too tight to scale meaningfully. Below 1:1 you're losing money on every new patient. 5:1 or higher usually means you're under-spending and leaving growth on the table.
How is CAC actually calculated?+
CAC = total marketing spend (retainers + ad spend + tools) divided by new patients acquired that period. Include everything you spend on marketing; exclude clinical costs. For a clinic spending $6,000/month and acquiring 30 new patients, CAC = $200 per new patient.
What counts as LTV for an aesthetic clinic patient?+
The 24-month lifetime value — total revenue a patient generates over their first two years. It includes the first treatment, average repeat treatments per year, and any membership revenue. For most Canadian med spas, non-member LTV runs $600-$1,500 and member LTV runs $3,000-$5,500.
Why is the payback period important?+
Payback period tells you how long until a new patient covers the cost of acquiring them. Under 6 months is excellent (fast cash flow), 6-12 months is normal, over 12 months means you need serious runway to scale marketing spend.
What if my ratio is below 2:1?+
Fix retention/LTV before scaling. Adding more budget to a low LTV:CAC ratio just loses money faster. Priorities: launch or fix your membership program, improve consultation-to-treatment conversion, build repeat-visit reminders, and improve patient experience to drive referrals.
