cost per treatment start: the full-arch marketing number that matters

Cost per lead is the easiest number to make look good. Cost per treatment start is the one that tells you whether your marketing works.

why cost per lead misleads

Ask most marketing vendors how things are going and you'll hear about leads: how many, and how cheap. It's an easy number to improve. Broaden the audience, loosen the form, run a giveaway, and cost per lead drops.

But a lead is a name and a phone number. It isn't a patient. If cheap leads are colder, harder to reach, or unable to finance treatment, your cost per case can go up while your cost per lead goes down.

the equation every implant practice runs

Whether you write it down or not, full-arch revenue comes from one chain of multiplication:

  • leads, times the share you actually reach
  • times the share of reached leads who book a consult
  • times the share of consults who show
  • times the share of shows who start treatment

how to calculate cost per start

Add up everything you spend to get patients to the consult in a month: ad spend, agency or marketing fees, and the people cost of working implant leads, whether that's a call center, setters, or front desk hours. Divide by the number of full-arch treatment starts that came from those leads.

Do it over at least a quarter. Full-arch decisions take time, and a single month is noisy. Track it by channel and campaign if you can, so you know which sources actually produce cases.

where the leverage is

Because the stages multiply, a small improvement in the middle of the chain is worth as much as a big increase in ad spend, and it costs far less. A few examples of what moves each stage:

  • Leads: better audiences and offers. Aim spend at people already shopping for implants instead of a whole radius.
  • Reached: answering every call live and calling form leads back in minutes, including nights and weekends.
  • Booked: a conversation that understands full-arch concerns and books the right people, not everyone.
  • Showed: financing known before the consult, confirmations, and reminders.
  • Started: a doctor and TC who walk in knowing the patient's situation, budget, and objections.

what to ask any implant marketing partner

Whoever you work with, these questions keep the conversation on what matters:

  • Will you report cost per treatment start, not just cost per lead?
  • Who answers my leads, how fast, and at what hours?
  • When does financing come up: before the consult or during it?
  • What does my doctor get before the consult?
  • What's the contract term if the numbers don't hold?
