Which reminder vendor pays for itself?
Most vendor ROI calculators use the vendor’s own reduction claim. This one starts from the peer-reviewed evidence (Hasvold and Wootton 2011: automated and SMS reminders about 29%, manual phone about 39%), applies a 28 to 38% band for a two-stage SMS program with confirmation, and ranks the platforms by what they actually return per month at your numbers.

Which vendor pays for itself?
Pick a specialty, set your monthly volume. The payback table re-ranks as you write.
76 no-shows a month. A 28 to 38% reminder reduction recovers $4,256 to $5,776 of monthly revenue.
Net = recovered monthly revenue minus the vendor’s midpoint subscription estimate. Vendor costs are estimated ranges from each platform’s pricing folio, not fixed quotes. Enterprise platforms (Artera, Luma Health) are quote-only and scoped to hospital systems, so they sit outside this per-practice table.
How the payback ranking works
The calculation is deliberately conservative. Monthly no-shows are your appointment volume times your no-show rate. The recovered figure applies a 28 to 38% band (33% midpoint) for a two-stage SMS program with confirmation, derived from Hasvold and Wootton 2011 (automated and SMS reminders about 29% of baseline, manual phone about 39%), not the 50%-plus reduction that vendor marketing often quotes. Recovered appointments convert to recovered revenue at your own per-visit figure. The net column is that recovered revenue minus each platform’s midpoint monthly subscription estimate.
The ranking flips with volume. At low monthly volume the cheapest tools (ReminderCall, Doctible) are often the only ones clearing break-even, because recovered revenue is small. As volume rises, every platform clears its cost easily and the ranking compresses, so the decision shifts from raw ROI to feature fit, EHR integration, and support, which is what the individual pricing folios cover.
Vendor subscription figures are estimated ranges (these platforms do not publish fixed list prices) drawn from procurement threads, G2 cost notes, and reseller documentation, and are labelled as estimates throughout. Treat the output as a directional comparison, not a quote.
