Cost of Attrition Calculator

Calculate the full annual cost of agent attrition beyond replacement hiring. Itemizes recruiting, training, productivity ramp, quality dip, overtime coverage, and institutional knowledge loss.

This tool quantifies the total annual cost of employee turnover across three categories. Direct costs include recruiting expense and training cost per hire, multiplied by annual departures (headcount x attrition rate). Ramp cost models the productivity gap during the proficiency period: new hires start at a configured day-1 productivity percentage and ramp linearly to 100% over the months-to-proficiency period. Each month's cost equals (1 - productivity_that_month) x monthly_salary. Overtime coverage cost accounts for the vacancy period: departures x average_weeks_vacant x weekly_salary x overtime_multiplier.

The model assumes linear productivity ramp (a simplification — actual ramps are typically S-curved with slower starts and faster mid-period learning). It also assumes all vacant positions require overtime coverage at the configured multiplier (typically 1.5x). The overtime calculation represents the minimum coverage cost; in practice, understaffing also degrades service levels, increases remaining-agent burnout, and can trigger cascading attrition.

Practitioners should use the cost-per-departure figure to build business cases for retention initiatives: any program costing less than this amount per agent retained is ROI-positive. The percentage-of-payroll metric contextualizes the problem for executive audiences. Contact centers with 35%+ attrition are typically spending 15-25% of payroll on turnover costs alone. The ramp curve visualization is particularly useful for justifying nesting programs, mentoring investment, and extended training — every month you can accelerate proficiency directly reduces the ramp cost component.
