Attrition Cost Calculator
Most leaders underestimate the cost of losing an employee because they only think about the recruiting fee. The real cost is spread across five components — separation, recruiting, vacancy, onboarding, and ramp-up productivity loss — and it adds up fast.
This calculator shows you where the money actually goes, so you can make better retention decisions.

Hidden Costs Not Captured Above
Institutional Knowledge
Experience at this organization is not fully portable. Huckman & Pisano (2006) found that surgeons’ performance advantages largely disappeared when they moved to a new hospital — their effectiveness was tied to familiar teams, systems, and context. When someone leaves, they take relationships, undocumented processes, and organizational memory with them.

Team Morale & Cascading Departures
Turnover is contagious. When a respected colleague leaves, it signals to others that leaving is an option — and the remaining team absorbs extra workload during the gap. Research estimates that one departure increases the probability of additional departures by 25–50% in the same team within 12 months.

Customer & Stakeholder Disruption
Client-facing or stakeholder-facing roles carry relationship equity that doesn’t transfer. A new person rebuilds trust from zero. In professional services, losing a key relationship manager can put 10–30% of that book of business at risk during transition.

Research basis: Replacement cost estimates draw from SHRM (“Retaining Talent”), Gallup (“The Real Cost of Employee Turnover”), the Center for American Progress (Boushey & Glynn, 2012), and Josh Bersin’s onboarding research. Ramp-up productivity modeled as an exponential learning curve (Heathcote, Brown & Mewhort, 2000). Time-to-fill defaults based on SHRM average of 44 days for mid-level roles.
This is a planning tool, not a prediction. Real costs vary by role complexity, labor market, knowledge transfer quality, and organizational support.
