Recruitment Metrics

Cost of Vacancy

Quick Definition

Cost of vacancy is a recruiting metric that estimates the financial impact of an open role remaining unfilled — capturing lost productivity, delayed output, overtime or contractor costs covering the gap, and the opportunity cost of work that simply doesn't get done — expressed as a dollar figure per day, week, or month the position stays open.

What Is Cost of Vacancy?

Cost of vacancy exists to answer a question that time-to-hire alone can't: not just how long a role stays open, but what that open time actually costs the business. A sales role generating $40,000 in monthly quota left unfilled for two extra months represents a very different cost of vacancy than an internal operations role of similar seniority left open for the same duration, even though both would show an identical time-to-hire figure.

The most common formula estimates cost of vacancy as the role's fully loaded compensation (salary plus benefits and overhead) divided by the estimated productivity or revenue the role would have generated, prorated to a daily rate, then multiplied by the number of days the position remains open. Revenue-generating roles — sales, billable consulting, production — lend themselves to a more direct calculation than support or internal-facing roles, where the cost is estimated instead through proxies like team overtime, delayed project timelines, or the burden absorbed by existing staff covering the gap.

Cost of vacancy is most useful not as a single static number but as a comparative tool across roles and business units — it reveals which open requisitions deserve the most urgent recruiting attention and executive escalation, independent of how long they've technically been open. A role with a high cost of vacancy sitting unfilled for three weeks may warrant far more urgent intervention than a low-cost-of-vacancy role that's been open for three months.

Building a credible cost of vacancy model requires close collaboration between recruiting, finance, and the hiring manager's own business unit — recruiting alone rarely has visibility into the actual revenue or productivity impact of a given open role, and a cost of vacancy figure produced without that input is likely to understate or overstate the real business cost significantly.

Why Cost of Vacancy Matters

Cost of vacancy reframes an open requisition from an abstract recruiting-process metric into a concrete business cost, giving recruiting leaders a genuinely persuasive way to secure executive attention and resources for the roles that matter most.

Key Benefits

Translates an open requisition into a dollar figure business leaders immediately understand and prioritize around
Helps recruiting teams triage which open roles deserve the most urgent attention, independent of time already elapsed
Provides a defensible business case for additional recruiting headcount or budget during peak hiring periods
Surfaces the true cost of a slow or bottlenecked hiring process in terms executives weigh alongside other business costs
Encourages hiring managers to engage more actively in a process they might otherwise treat as purely recruiting's responsibility
Creates a shared, cross-functional metric that aligns recruiting, finance, and business unit leadership

Common Use Cases

Prioritizing which of dozens of simultaneously open requisitions deserve the most recruiter attention and executive escalation

Building a business case for additional recruiting budget or headcount during a high-growth hiring period

Quantifying the cost of a bottlenecked interview process to secure faster hiring manager engagement

Comparing the true cost of an extended search for a specialized role against the cost of a faster, lower-bar hire

Frequently Asked Questions

What is cost of vacancy?

Cost of vacancy is a recruiting metric estimating the financial impact of an open role remaining unfilled — including lost productivity, delayed output, and overtime or contractor costs covering the gap — expressed as a dollar figure per day, week, or month the position stays open.

How is cost of vacancy calculated?

The most common formula divides a role's fully loaded compensation by its estimated productivity or revenue contribution, prorates that to a daily rate, and multiplies by the number of days the role stays open. Revenue-generating roles allow a more direct calculation than support roles, which typically rely on proxies like overtime or delayed project timelines.

How is cost of vacancy different from cost per hire?

Cost per hire measures what it costs to fill a role — recruiting spend, agency fees, advertising. Cost of vacancy measures what it costs the business for the role to remain unfilled — lost productivity and delayed output. The two are complementary but measure opposite sides of the hiring timeline.

Why is cost of vacancy useful for prioritizing open roles?

It reveals which open requisitions carry the highest genuine business cost, independent of how long they've technically been open. A high-cost-of-vacancy role open for a few weeks may warrant more urgent attention than a lower-cost role that's been open much longer.
