The Real Cost of Employee Turnover

The Real Cost of Employee Turnover: A Worked Model for a 40-Person Company

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). For a 40-person company paying an average of $65,000 with 15% annual turnover, that is six departures and roughly $390,000-$585,000 a year – the size of an entire department payroll, hiding in plain sight.

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 is 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

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)

ItemEstimate
Exit interview, offboarding admin, IT deprovisioning$500
Accrued leave payout (8 days)$2,000
Knowledge-transfer sessions$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). The work does not disappear; it is absorbed badly:

ItemEstimate
Lost output of the vacant seat (50% of daily value × 50 days)$6,250
Overtime/spillover to teammates (~10% for 3 people)$4,500
Manager time re-planning and covering$1,750

Bucket 3 – Hiring costs (~$9,600)

ItemEstimate
Job boards + LinkedIn ads$1,200
Recruiter/sourcing time (internal, ~30 hrs)$1,500
Interview time: 5 interviewers × 4 candidates × 1.5 hrs$2,400
Screening tools, background check$500
Agency fee amortised (1 in 3 hires)$4,000

Bucket 4 – Ramp-up costs (~$21,700)

A new professional hire takes roughly 3-6 months to reach full productivity:

ItemEstimate
Months 1–3 at ~50% productivity$8,100
Months 4–6 at ~75% productivity$4,100
Trainer/buddy time (10% of senior colleague)$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.

Scaling it up: the 40-person company

At 15% annual turnover, a 40-person company loses six people a year:

6 departures x $47,100 = $283,000/year (conservative)
6 x 90% of salary = $351,000/year (SHRM mid-range)

Cutting turnover from 15% to 10% (two fewer departures) saves ~$94,000 a year. The Retention Rate Calculator shows where you stand.

Regrettable vs non-regrettable departures

  • Regrettable (strong performer you wanted to keep): full model cost, often 100%+ of salary.
  • Non-regrettable (performance exit): separation and hiring costs still apply, but lower overall.

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. (Time to Hire is the lever there.)

The India version (40-person company, Rs.8L salary)

BucketEstimate
SeparationRs.55,000
Vacancy (50-day fill)Rs.1,50,000
HiringRs.1,40,000
Ramp-upRs.2,60,000
Total per departureApprox. Rs.6,05,000 (~75% of salary)

At 15% turnover: 6 x Rs.6,05,000 = Rs.36 lakh a year. See also: Leave Encashment Calculator.

FAQ

Is 15% turnover bad? It depends on industry – 8-12% is typical for professional services, 60%+ is normal in hospitality.

Should I include internal transfers? No – count only exits from the organisation.

Cheapest intervention with the best evidence? Manager quality. Departures cluster under specific managers; coaching those two usually beats an across-the-board perk.
