Losing a client quietly costs wellbeing practices far more than winning a new one

Back in 2014, Harvard Business Review dusted off Bain & Company's long-standing finding that winning a new customer costs anywhere from five to twenty-five times more than keeping an existing one, and this applies just as much to practices like yours as it does to any high street bank.

Practices that spend most of their energy chasing new enquiries, while existing clients quietly drift away, are working a great deal harder than they need to.

Original Research	HBR's case for why retaining the right customers is worth more than most businesses assume
Source	https://hbr.org/2014/10/the-value-of-keeping-the-right-customers
Overview	The article summarises decades of customer retention research by Frederick Reichheld and Bain & Company, published as a strategy piece in Harvard Business Review.
Year	2014
Publisher	Media, Harvard Business Review (citing Bain & Company research)
Relevance to Wellbeing	The underlying economics apply to any small practice with a client list, regardless of how the treatment or session is delivered.
Our Verdict	Too early to tell the core finding is old but still widely accepted, even if the original methodology behind the "5 to 25 times" figure isn't spelled out here.
Our Summary	Backed by one of the most cited names in customer loyalty research, so it's not a number someone made up on a Tuesday. The logic holds regardless of practice size, which is useful when your marketing budget is, let's say, modest. The exact study behind the "five to twenty-five times" figure isn't shown, so the number should be treated as directional rather than gospel. Written for general business audiences, not wellbeing specifically, so nobody was thinking about client retention in a therapy room when they wrote it.
Our Geo View	Applies broadly to all countries

Recognise how this might impact your practice

Why this might matter to you

Coaching: this matters because a coach chasing new sign-ups while ignoring lapsed clients is paying full price for growth that was sitting there already, half-finished.
Therapy: this matters because a client who quietly stops booking is far cheaper to win back with one thoughtful check-in than any client is to find from scratch.
Training: this matters because a trainer who treats every cohort as a one-off is throwing away the cheapest source of repeat bookings there is.
Alternative Healing: this matters because trust takes a while to build in this line of work, which makes losing it, and having to rebuild it with someone new, an expensive habit.
Clinical: this matters because a clinic with a full waiting list can still be losing money quietly if existing patients aren't being retained for ongoing care.
Retreat/Centre: this matters because a retreat that never hears from last year's guests again is spending its whole marketing budget on strangers.

Where this came from

Harvard Business Review revisited the well-worn argument that businesses chronically underinvest in keeping the customers they already have.

Harvard Business Review, published October 2014. The core statistic is drawn from Bain & Company's retention research, associated with Frederick Reichheld, and is cited here rather than sourced first-hand.

Credibility flags: methodology not disclosed in this article, sample size not stated, publisher type media commentary on industry research.

How we scored this

A relevance score out of 100, built from three things: how well it fits the six practice types, how recent it is, and how solid the methodology behind it is.

21%

Practice fit, 25How new, 10How solid, 25

Marked down mainly on how solid the method is, since the original study isn't shown, and on recency given the piece is over a decade old, though its practice fit holds up well as a general business principle.

It's worth considering changes to your marketing practices

What this means for your marketing

Put a simple "we haven't seen you in a while" message in front of any client who's gone quiet for more than a couple of months.
Say the retention argument out loud in your own copy, something like "most of our clients stay because it works", before a prospect starts comparing prices elsewhere.
Brief your team on treating a lapsed client enquiry as more valuable than a cold one, and prioritise it accordingly.
Set aside a small, recurring slice of your marketing time for existing clients rather than pouring it all into new leads.
Track how many of your bookings come from returning clients this quarter, then use that number in your own marketing rather than guessing.

Who this is most useful for

Practice type	Relevance	Recommended action
Coaching	High	Build a simple re-engagement email for lapsed clients.
Therapy	High	Add a gentle check-in step after a client's last booked session.
Training	Medium	Offer past attendees first access to new courses.
Alternative Healing	Medium	Ask former clients directly what would bring them back.
Clinical Practices	Medium	Review patient recall processes for ongoing care gaps.
Retreats/Centres	High	Stay in touch with past guests between retreats, not just before booking opens.

Best before

Best before: this is a foundational, slow-moving principle rather than a fast-changing statistic, but given the piece is now over a decade old, it's worth re-checking against a current Harvard Business Review source or Bain's own published research before quoting the exact multiplier again.
