Estimated savings based on your assumptions
$459,000/year
Based on your inputs, your organization has approximately 24 regrettable departures per year, each costing an estimated $127,500 to replace.
Replacement-cost assumption based on SHRM research showing employee replacement costs 0.5–2× annual salary. The attrition-reduction percentage above is an assumption you set, not a verified MentorStack result. MentorStack launched in 2026 and has no customer case studies yet. Once you are live, the Retention report (Growth, with HRIS) shows the directional trend for participants against your baseline. It is not a causal measure.
