Free client lifetime value (CLV) calculator for service business owners. Knowing what a client is worth over their lifetime changes how you think about every booking and every lapsed customer. Enter your session rate, booking frequency, and typical client lifespan to find out.
Aasure tracks every client's value, flags lapses before they happen, and runs the win-back messages automatically — so the lifetime profit you just calculated actually lands.
Join the WaitlistService businesses think about clients in singles — the booking that just came through, the one that didn't, the regular who comes in every six weeks. But the unit that actually drives the business is the lifetime: how many sessions a client books over their full relationship with you, multiplied by what they spend.
This calculator turns that into a single number. You enter your average price, how often a typical regular books, and how long they stay. The output is the lifetime value — the figure that should anchor every decision about marketing budgets, retention effort, and whether to chase a marketplace listing that takes 20% off the top.
The number usually surprises people. A salon client at £80 every six weeks for three years is £2,080. A personal trainer client at £60 a session twice a week for two years is £12,480. Once you see the lifetime number, the maths around commissions, no-shows, and follow-ups all changes shape.
It is the total revenue a client generates across their full relationship with your business — not just one booking. For most service businesses it is calculated as average session price × sessions per year × years as a client.
Because the marketing, retention, and software decisions you make affect lifetime, not single bookings. A 20% commission on every appointment, for example, looks small per booking but huge across a three-year relationship.
Three levers move it: book frequency (reminders, follow-ups, retention nudges), session price (annual reviews, package pricing), and length of relationship (great service, plus the small admin that keeps people from drifting — birthday note, six-month check-in, anniversary discount).
