Calculator methodology

How the illustrative estimate is calculated.

The calculator combines editable clinic inputs with clearly labelled research defaults. It does not forecast SensaAI performance.

Missed calls

Monthly inbound calls × missed-call rate

Missed bookings

Missed calls × appointment-intent rate × booking conversion rate

Appointment capacity value at risk

Missed bookings × average appointment value

Illustrative monthly value affected

Missed bookings × average appointment value

Default assumptions

Monthly inbound calls: 6000
Missed-call rate: 40%
Appointment-intent rate: 48%
Booking conversion rate: 40%
Average appointment value: $51.40

Model assumptions

Annualized estimates multiply the monthly result by 12.

Plain-language glossary

Research terms without the jargon.

No-show: A booked appointment the patient does not attend.
Percentage point: The direct difference between two percentages. A fall from 10% to 8% is 2 percentage points.
Meta-analysis: A study that combines results from several earlier studies.
Relative risk (RR): A comparison between how often an outcome happens in two groups. An RR below 1 means it happened less often in the studied group.
Fee-for-service: A payment model where a clinician receives a listed amount for an eligible service.
Gross clinical payment: The amount paid before clinic overhead, wages, taxes, and other costs. It is not profit.

Limitations

What this evidence cannot tell you.

Canadian clinic-specific call-volume data is not publicly available.
The Canadian no-show study is single-site and is not a national average.
Vendor benchmarks are self-published and may not reflect an Ontario clinic.
SensaAI does not yet publish its own outcome data.
