"$1 spent, $40 saved" requires the $1 actually be spent on the right thing
The 40x figure is well-cited but assumes a particular spend mix. Buying more email-gateway licences gets you very little additional reduction past a baseline. Buying a behaviour-change platform with monthly simulation, role-based content, and reporter telemetry returns the published ROI. Treat the multiplier as the upper bound of a layered, sustained programme, not a guaranteed outcome of an annual click-through training module.
