Short answer: replacing one employee typically costs 50-60% of their annual salary in direct costs, and 90-200% in total costs 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 – 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.
Why turnover cost feels invisible
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 total it suddenly find their retention proposals getting funded.
The model below splits the cost into four buckets. Work through them once with your own numbers – our Cost Per Hire Calculator and Employee Turnover Calculator handle the arithmetic.
The model: one departing employee at $65,000
Meet the departure: a mid-level employee at a 40-person services company, $65,000 salary (~$250/working day), giving two weeks’ notice.
Bucket 1 – Separation costs (~$3,300)
| Item | Estimate |
|---|---|
| Exit interview, offboarding admin, IT deprovisioning | $500 |
| Accrued leave payout (say 8 days) | $2,000 |
| Knowledge-transfer sessions (4 hrs departing + 6 hrs colleagues) | $800 |
Bucket 2 – Vacancy costs (~$12,500)
The role sits empty for the time it takes to fill it – say 50 days (Time to Fill for a professional role). The work doesn’t disappear; it’s absorbed badly:
| Item | Estimate |
|---|---|
| Lost output of the vacant seat (conservatively 50% of daily value × 50 days) | $6,250 |
| Overtime / spillover to teammates (drag on their output, ~10% for 3 people) | $4,500 |
| Manager time re-planning and covering | $1,750 |
Bucket 3 – Hiring costs (~$9,600)
This is the classic cost-per-hire bucket – the only one most companies ever measure:
| Item | Estimate |
|---|---|
| Job boards + LinkedIn ads | $1,200 |
| Recruiter/sourcing time (internal, ~30 hrs) | $1,500 |
| Interview time: 5 interviewers × 4 candidates × 1.5 hrs loaded cost | $2,400 |
| Screening tools, background check | $500 |
| Agency fee – if used, 15-20% of salary; assume 1-in-3 hires uses one (amortised) | $4,000 |
Bucket 4 – Ramp-up costs (~$21,700)
The biggest and least-measured bucket. A new professional hire takes roughly 3-6 months to reach full productivity:
| Item | Estimate |
|---|---|
| Months 1-3 at ~50% productivity (salary paid vs value delivered) | $8,100 |
| Months 4-6 at ~75% productivity | $4,100 |
| Trainer/buddy time (10% of a senior colleague for a quarter) | $2,400 |
| Formal training, tools, certifications | $1,600 |
| Elevated error/rework rate during ramp | $2,500 |
| Manager 1:1 overhead above steady state | $3,000 |
The total
$3,300 + $12,500 + $9,600 + $21,700 ≈ $47,100 – about 72% of salary. 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.
Scaling it up: the 40-person company
Now multiply by your turnover rate. At 15% annual turnover – the US cross-industry norm is 12-15% – a 40-person company loses six people a year:
6 departures × $47,100 ≈ $283,000/year (conservative)
6 × 90% of salary ≈ $351,000/year (SHRM mid-range)
Check your own rate with the Employee Turnover Calculator – 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 shows where you stand against your industry benchmark.
Which departures actually matter: regrettable vs non-regrettable
A blended average hides the real lever. Split your departures:
- Regrettable (strong performer you wanted to keep): full model cost, often 100%+ of salary – these are the expensive ones, and they cluster under specific managers and in specific salary-vs-market gaps.
- Non-regrettable (performance exit, mutual mismatch): the separation and hiring buckets still apply, but the vacancy may even raise team output. Cost is real but much lower.
If 4 of your 6 departures are regrettable, your problem is retention. If 4 are non-regrettable, your problem is hiring quality – fix the funnel, not the perks. (Your Time to Hire and interview process are the levers there.)
The ₹ version (India, 40-person company)
Same structure, Indian mid-level salary of ₹8,00,000 (~₹3,100/working day):
| Bucket | Estimate |
|---|---|
| Separation (offboarding, leave encashment, knowledge transfer) | ₹55,000 |
| Vacancy (50-day fill, absorbed work, manager time) | ₹1,50,000 |
| Hiring (Naukri/LinkedIn, interviews, 1-month-salary agency fee amortised) | ₹1,40,000 |
| Ramp-up (3-6 month productivity curve, buddy time, training) | ₹2,60,000 |
| Total per departure | ≈ ₹6,05,000 (~75% of salary) |
At 15% turnover: 6 × ₹6,05,000 ≈ ₹36 lakh a year – before counting gratuity provisioning and leave encashment on longer-tenured exits.
FAQ
Is 15% turnover bad? It depends on industry – 8-12% is typical for professional services, 60%+ is normal in hospitality. Compare against your industry, not the overall average, and watch the trend more than the level.
Should I include internal transfers? No – an internal move keeps the knowledge and usually the productivity. Count only exits from the organisation.
What’s the cheapest intervention with the best evidence? Manager quality. Departures cluster under specific managers in nearly every dataset; training or coaching the two managers with the worst team attrition usually beats an across-the-board perk on ROI.
How precise does my model need to be? Directionally right beats falsely precise. Even the conservative version – direct costs only, ~50% of salary – is usually enough to justify the retention budget you’re asking for.
