Is keeping a patient really cheaper than winning a new one?
Almost certainly yes for your clinic, but do not take the famous five-times figure on faith; it is endlessly quoted and rarely sourced. Compute both sides yourself in ten minutes: acquisition cost is last quarter's marketing spend divided by genuinely new patients; retention cost is what a follow-up message and the system that sends it costs per returned patient. For most clinics the first number is tens to hundreds of dollars and the second is single digits. That gap, whatever it is exactly, is the argument.
Your acquisition cost, honestly
Total what you spent last quarter on ads, directories, marketplaces and promotions. Divide by new patients who actually attended. Clinics doing this for the first time regularly find a number well above what they would have guessed, because the spend is spread across many small line items.
Your retention cost, honestly
Count the cost of contacting a lapsed patient: a few cents of message, a share of whatever tool sends it. Even fully loaded with Routiq's subscription, a clinic that wins back a handful of patients a month is paying single-digit dollars per returned patient. And the returned patient books faster, because trust already exists.
What the gap means for budget
It does not mean stop acquiring. It means sequence: close the rebooking-report leak first, because every acquired patient eventually flows through the same leaky retention pipe. Fill the bucket after you patch it, and your acquisition spend compounds instead of replacing losses.
Quick answers
Where does the 'five times cheaper' figure come from?
It circulates in marketing literature with no consistent primary source, which is why we suggest computing your own ratio. Your real numbers are more persuasive than anyone's slogan, including ours.
