This is a modeled estimate, not a guarantee. Defaults come from published sources: the 30–50% missed-call range from 2026 industry research (conservative low end used), and per-appointment revenue derived from the published Cardinale Mazda result ($88K month-one revenue, 238 appointments, 79% success ratio). Your numbers depend on call mix, hours, and scheduler capacity — every input above is editable. Nothing you enter is stored or transmitted.
