Your gym, roughly
A conservative slice of the leak above — the renewals you’d save just by never missing a due date.
How this is worked out (honest, conservative):
Yearly leak = (members who lapse/renew late per month) × (monthly fee) × 12. That’s the revenue at risk when renewals aren’t chased on time.
Recoverable = 60% of that leak — assuming you win back most (not all) of those renewals simply by seeing every due on time and sending a one-tap reminder.
Hours back = (admin hours/week) × 52 × 70% — the share of register-keeping, manual reminders, and cash-book adding that the app just does for you.
These are your inputs and round assumptions, not a promise. Slide the numbers to match your reality.
