Your estimated ROI

Estimated savings based on your assumptions

Annual cost of regrettable attrition$3,060,000
Annual MentorStack cost (Starter)$72,000

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're live, track your program's actual retention impact with the built-in Retention report.
