What Does Employee Turnover Actually Cost?

Start with the right departures

The Bureau of Labor Statistics distinguishes quits, layoffs and discharges, and other separations in JOLTS. An employer should likewise state which departures are in scope before interpreting a turnover total. A retirement and a preventable resignation need not imply the same action. [1]

Build a cost ledger, not a universal multiplier

Our proposed worksheet separates three categories. Direct expenses include invoices such as advertising or temporary coverage. Internal time includes documented recruiting and onboarding hours. Capacity effects are modeled estimates of work delayed or not completed. Keep the categories visible so a reader can challenge an assumption without discarding the entire estimate.

Do not count the same work twice. If temporary coverage restored an output, adding both its full cost and the full value of that supposedly missing output could overstate the loss. Similarly, an employee’s allocated time is not automatically an additional cash expense.

An illustrative break-even calculation

Suppose an employer considers a $60,000 retention initiative and estimates $15,000 of avoidable cost per departure. Four avoided departures would cover the initiative’s cost under those assumptions. This is arithmetic, not a prediction that the initiative will prevent four departures.

Repeat the calculation with lower and higher cost assumptions. Record which expenses would actually disappear and which represent redeployed time. If the decision only works under an optimistic capacity estimate, that uncertainty belongs beside the headline result.

Decide what the estimate can tell you

A cost model can establish a planning threshold. It cannot establish that a specific intervention caused retention to improve. Evaluation guidance distinguishes observed change from attributable impact and requires a defensible comparison for a causal claim. [2]

What to collect next

For one role, assemble recent hiring invoices, coverage records, recruiting time, and onboarding milestones. Agree on the period and definition of a departure. Use the same basis when comparing scenarios, and keep employee experience separate from the dollar ledger.
