Voluntary Attrition Replacement Cost Calculator
When an employee quits, the replacement cost is rarely just recruiter fees. SHRM puts the true cost at 50-200% of annual salary once productivity ramp, knowledge loss, and manager time are added in.

Voluntary attrition is one of the largest controllable costs in any people-heavy business. SHRM data puts the true cost of replacing a knowledge worker at 50-200% of annual salary once recruiter fees, vacancy productivity loss, ramp time, manager interview hours, and knowledge transfer are added. This calculator forces you to surface the hidden costs that almost never appear on a single budget line.
What Drives the Real Cost
Direct costs — recruiter fee, signing bonus, relocation — are easy to count but usually only 15-25% of the total. The hidden majority comes from vacancy productivity loss (an open seat in a critical role can cost 100% of daily wage for 60+ days), ramp productivity loss (new hires run at ~50% productivity for the first 6 months), and manager and team interview time (40-120 hours diverted from billable work). Knowledge transfer and undocumented processes add another 5-15%.
How to Use the Number
Most companies underspend on retention by 5-10x. If replacing a senior engineer costs 150% of their $180K salary ($270K), then a $20K spot bonus or a $15K learning budget is a cheap insurance policy. Calculate the per-departure cost by level, multiply by your voluntary attrition rate, and compare it to what you spend on retention programs. Most leaders are stunned by the gap. Reallocate budget from external recruiting to internal mobility, manager training, and stay interviews — payback is typically under 12 months.
