Reminder ROI calculator
Estimate the value of reducing no-shows after paying for SMS or call reminders.
What this calculator covers
This reminder roi calculator is publisher content for UK private clinics, therapists, and physios. You supply average appointments per month, no-show rate before reminders, no-show rate after reminders, average session value, and monthly reminder cost. It reports estimated extra sessions kept, estimated gross benefit, and estimated net after reminder cost using the simplified assumptions described below—not as a substitute for an accountant, solicitor, or clinical record.
Reminders can recover appointments that would otherwise be lost. Enter your baseline and improved no-show rates, average session value, monthly appointment volume, and reminder spend.
The result is illustrative: attribution is never perfect, and compliance rules apply to messaging patients.
What this model does not do
This reminder roi calculator is original publisher copy for UK private clinic administration. It does not measure creative quality or ad-auction dynamics. Ratios are only as good as how you count enquiries and bookings.
The form cannot see your contracts, payer mix, or diary software. If a clause matters and there is no field for it, the output will not include it.

How it works
-
Enter average appointments per month
For this Reminder ROI model, enter average appointments per month, no-show rate before reminders, no-show rate after reminders, average session value, and monthly reminder cost. Keep those definitions consistent with your diary or management accounts.
-
Read estimated extra sessions kept
The reminder roi model then reports estimated extra sessions kept, estimated gross benefit, and estimated net after reminder cost. The arithmetic runs in your browser; we do not receive the numbers you type.
-
Check against marketing & growth records
Treat estimated extra sessions kept and estimated gross benefit as planning figures for marketing & growth conversations, then confirm VAT, contracts, and filings with your own records and qualified advisers.
Context and how to use this
Estimates gross benefit if reminders shrink no-show rates, minus reminder spend. Attribution is imperfect—treat as directional.
Comply with messaging rules and patient marketing preferences.
Common questions
- Why two no-show rates?
- They represent before and after a change you believe reminders caused. If you lack data, run sensitivity cases.
- Net benefit negative?
- Reminder cost may exceed recovered revenue at low volumes or small improvements—still useful information.
