Calculators

Retention calculations

Each page gives a formula and a worked example you can repeat with your own numbers in a spreadsheet. The examples use fictional figures.

Value

What a customer is worth

Revenue per visit, visits per year and years retained, then margin.

Revenue vs contribution, and what visit history cannot establish.

Rates

Pick the formula that fits your business and state the window.

Share of first-time customers who complete a second visit.

Next visits booked against eligible visits, with a clear deadline.

Customers lost from a starting group, divided by that group.

Returns among a defined lapsed group.

Completed returns from a defined win-back audience.

Score

40% first to second visit, 60% return adherence, from completed visits.

These are worked calculations, not interactive calculators. Inside RetentionTek, the Retention Score is calculated from your imported visit history.
