Dogs and cats seen at least once in the last two years.
Boosters, parasite treatments given in the clinic, annual check-ups.
If you don’t know, keep 70%. For reference, 82% of UK dogs and 66% of UK cats got regular boosters in 2026 (PDSA PAW 2026).
Consultation plus vaccine or treatment, in euros.
Your assumption. We default to 8%: a single email campaign brought back 8.5% of inactive clients across 1,612 US practices in 2015–16 (AAHA NEWStat, 2017), and reminders raised human vaccination uptake by 8 points (Cochrane, 2018).

How the calculation works
Four multiplications, no hidden factors.
- Visits dueActive patients × preventive visits due per pet per year.
- Visits missedVisits due × (100% − share that happens today).
- Revenue at stakeVisits missed × average visit value.
- Revenue brought backVisits missed × share reminders bring back × average visit value.
The calculator leaves out referrals, extra procedures found during a visit, and the longer life of a client who returns, so the real value of a returning patient is usually higher.

Your client list turns this estimate into names: who is overdue, for what, and what those visits are worth.
