    Why is it worth recovering clients?

    One assumption and two published findings, rather than three round numbers

    30%
    What this calculator assumes
    That roughly a third of customers do not come back. It is an assumption, not a measurement: no published lapse rate for service businesses fits every trade. Read the result as a what-if against your own books.

    What a returning customer is worth
    In auto servicing, a fourth-year customer produced more than three times the profit of a first-year one, across more than 100 companies studied by Harvard Business Review in 1990.

    What a reminder changes
    Take-up of something that had come due was 1.29 times likelier after a text reminder, across six randomised trials of vaccination reminders rated high certainty by Cochrane.
