Short answer:<\/strong> replacing one employee typically costs 50-60% of their annual salary in direct costs<\/strong>, and 90-200% in total costs<\/strong> once you count lost productivity, ramp-up time, and the load on the rest of the team (SHRM’s long-standing estimate). For a 40-person company paying an average of $65,000 with 15% annual turnover, that’s six departures and roughly $390,000-$585,000 a year<\/strong> – the size of an entire department’s payroll, hiding in plain sight. Here is the line-by-line model behind that number, so you can build your own instead of quoting someone else’s.<\/p>\n\n\n\n

Why turnover cost feels invisible<\/h2>\n\n\n\n

No invoice ever arrives that says “employee departure: $78,000.” The cost is smeared across a dozen budget lines – a job-board charge here, a recruiter fee there, three months of a new hire at full salary but half output – so it never gets totalled. Finance sees each fragment as normal operating noise. That’s exactly why HR teams that do<\/em> total it suddenly find their retention proposals getting funded.<\/p>\n\n\n\n

The model below splits the cost into four buckets. Work through them once with your own numbers – our Cost Per Hire Calculator<\/a> and Employee Turnover Calculator<\/a> handle the arithmetic.<\/p>\n\n\n\n

The model: one departing employee at $65,000<\/h2>\n\n\n\n

Meet the departure: a mid-level employee at a 40-person services company, $65,000 salary (~$250\/working day), giving two weeks’ notice.<\/p>\n\n\n\n

Bucket 1 – Separation costs (~$3,300)<\/h3>\n\n\n\n
Item<\/th>Estimate<\/th><\/tr><\/thead>
Exit interview, offboarding admin, IT deprovisioning<\/td>$500<\/td><\/tr>
Accrued leave payout (say 8 days)<\/td>$2,000<\/td><\/tr>
Knowledge-transfer sessions (4 hrs departing + 6 hrs colleagues)<\/td>$800<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

Bucket 2 – Vacancy costs (~$12,500)<\/h3>\n\n\n\n

The role sits empty for the time it takes to fill it – say 50 days (Time to Fill<\/a> for a professional role). The work doesn’t disappear; it’s absorbed badly:<\/p>\n\n\n\n

Item<\/th>Estimate<\/th><\/tr><\/thead>
Lost output of the vacant seat (conservatively 50% of daily value \u00d7 50 days)<\/td>$6,250<\/td><\/tr>
Overtime \/ spillover to teammates (drag on their output, ~10% for 3 people)<\/td>$4,500<\/td><\/tr>
Manager time re-planning and covering<\/td>$1,750<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

Bucket 3 – Hiring costs (~$9,600)<\/h3>\n\n\n\n

This is the classic cost-per-hire<\/a> bucket – the only one most companies ever measure:<\/p>\n\n\n\n

Item<\/th>Estimate<\/th><\/tr><\/thead>
Job boards + LinkedIn ads<\/td>$1,200<\/td><\/tr>
Recruiter\/sourcing time (internal, ~30 hrs)<\/td>$1,500<\/td><\/tr>
Interview time: 5 interviewers \u00d7 4 candidates \u00d7 1.5 hrs loaded cost<\/td>$2,400<\/td><\/tr>
Screening tools, background check<\/td>$500<\/td><\/tr>
Agency fee – if used, 15-20% of salary; assume 1-in-3 hires uses one (amortised)<\/td>$4,000<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

Bucket 4 – Ramp-up costs (~$21,700)<\/h3>\n\n\n\n

The biggest and least-measured bucket. A new professional hire takes roughly 3-6 months to reach full productivity:<\/p>\n\n\n\n

Item<\/th>Estimate<\/th><\/tr><\/thead>
Months 1-3 at ~50% productivity (salary paid vs value delivered)<\/td>$8,100<\/td><\/tr>
Months 4-6 at ~75% productivity<\/td>$4,100<\/td><\/tr>
Trainer\/buddy time (10% of a senior colleague for a quarter)<\/td>$2,400<\/td><\/tr>
Formal training, tools, certifications<\/td>$1,600<\/td><\/tr>
Elevated error\/rework rate during ramp<\/td>$2,500<\/td><\/tr>
Manager 1:1 overhead above steady state<\/td>$3,000<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

The total<\/h3>\n\n\n\n

$3,300 + $12,500 + $9,600 + $21,700 \u2248 $47,100 – about 72% of salary.<\/strong> That lands inside SHRM’s 50-200% band, toward the conservative end: this model assumes a smooth 50-day fill and no client churn. For a client-facing or specialised role, add lost-account risk and the number climbs past 100% quickly.<\/p>\n\n\n\n

Scaling it up: the 40-person company<\/h2>\n\n\n\n

Now multiply by your turnover rate. At 15% annual turnover<\/strong> – the US cross-industry norm is 12-15% – a 40-person company loses six people a year:<\/p>\n\n\n\n

6 departures \u00d7 $47,100 \u2248 $283,000\/year<\/strong> (conservative)<\/p><\/blockquote>\n\n\n\n

6 \u00d7 90% of salary \u2248 $351,000\/year<\/strong> (SHRM mid-range)<\/p><\/blockquote>\n\n\n\n

Check your own rate with the Employee Turnover Calculator<\/a> – and note the flip side: cutting turnover from 15% to 10% (two fewer departures) saves ~$94,000 a year. That’s the budget case for almost any retention programme: manager training, market-rate salary adjustments, or stay interviews cost a fraction of that. The Retention Rate Calculator<\/a> shows where you stand against your industry benchmark.<\/p>\n\n\n\n
