A plant manager has had a maintenance technician opening for eleven weeks. The role is approved and budgeted, so on paper the vacancy looks like savings: no salary is going out the door. In practice, two technicians are working Saturdays at overtime rates, a preventive maintenance schedule has slipped, and the manager spends part of every week reviewing resumes and covering gaps. None of that shows up as a line item called "vacancy cost," but the business is paying it.
Most employers track what it costs to fill a job. Fewer track what it costs to leave one open. This guide gives you a simple way to estimate that number so you can make better decisions about how fast to hire, where to spend recruiting dollars and when outside help makes sense.
Key Takeaways
- An open role is rarely free. Unpaid salary is often offset by overtime, lost output, delayed revenue and manager time.
- Estimate vacancy cost per week, then multiply by how long your roles actually stay open.
- Use your own numbers. A rough estimate built from real payroll and revenue data beats a generic industry figure.
- Compare the weekly vacancy cost to the cost of speeding up the search before deciding how to recruit.
- Shortening the steps inside your control, such as intake, scheduling and feedback, often saves more than any other change.
Why the budget savings are misleading
When a position sits open, the salary line goes quiet and finance may see a temporary saving. But the work the role was created to do does not disappear. It gets absorbed, delayed or dropped, and each of those has a price.
- Absorbed work usually means overtime or extra hours from the team, plus slower output on their own jobs.
- Delayed work can mean postponed projects, slower customer response or revenue that lands later than planned.
- Dropped work can mean missed opportunities, deferred maintenance or quality checks that do not happen.
The goal is not to produce a perfect figure. It is to replace "the vacancy is saving us money" with a realistic estimate everyone can see.
The vacancy cost worksheet
Work through these five lines for one open role. Estimate each as a weekly amount, then add them up. Use numbers from payroll, finance and the hiring manager rather than guesses where you can.
1. Overtime and extra hours
Who is covering the work, and how many extra hours per week? For nonexempt employees covered by the Fair Labor Standards Act, hours over 40 in a workweek must generally be paid at no less than one and one half times the regular rate, according to the U.S. Department of Labor. That premium adds up quickly when coverage stretches over months.
Formula: extra hours per week x overtime rate.
2. Temporary coverage
If you are paying a temporary worker, contractor or another department to fill the gap, include that weekly cost. Subtract the salary you are not paying only if the coverage fully replaces the role.
3. Lost or delayed output
This is the hardest line and often the largest. Ask the hiring manager what does not get done each week without this person. For revenue roles, it may be billable hours, units shipped or deals in progress. For support roles, it may be backlog, slower turnaround or deferred work.
Formula for revenue roles: expected weekly revenue or output from the role x the share that is actually lost or delayed. Be conservative. If the team covers half the work, count only the other half.
4. Manager and team time
Count the hours the hiring manager and team spend covering tasks, screening resumes, interviewing and onboarding replacements. Multiply by a loaded hourly cost. This time comes out of their own priorities.
5. Risk and quality costs
Some vacancies raise the chance of errors, safety incidents, missed deadlines, compliance gaps or customer churn. You may not be able to price these precisely, but list them. A note that says "two missed customer deadlines this month" is useful even without a dollar figure.
A hypothetical example
The numbers below are a made-up illustration, not a benchmark. Your figures will be different.
A distribution company has an open shift supervisor role. Two leads are covering, each working five extra hours a week at an overtime rate of $45 per hour. The operations manager spends about four hours a week covering tasks and interviewing, at a loaded cost of $70 per hour. Without a dedicated supervisor, the company estimates it is losing roughly $600 a week in productivity and errors.
| Line | Weekly estimate |
|---|---|
| Overtime (10 hours x $45) | $450 |
| Manager time (4 hours x $70) | $280 |
| Lost productivity and errors | $600 |
| Total | $1,330 |
If the role stays open for 12 weeks, the estimated vacancy cost is about $15,960. If a faster search fills it in 6 weeks, the company avoids roughly half of that. That comparison is what makes the number useful.
Turn the estimate into a decision
Once you have a weekly figure, you can answer practical questions:
- How urgent is this role? Roles with the highest weekly vacancy cost should get recruiting priority and faster interview scheduling.
- Is it worth spending more to fill it faster? Compare the cost of extra advertising, referral bonuses or outside recruiting help to the weeks of vacancy cost it could save.
- Should we cover it with contract help? If the search will take time, short term coverage may cost less than overtime and lost output.
- Where is our process slow? Track how many days each stage takes. Delays in approvals, interview scheduling and feedback are often within your control.

Shorten the time a role stays open
Every week you remove from the process saves one week of vacancy cost. Common places to recover time:
- Align before you post. A clear intake meeting prevents reposting and re-screening later. Use our hiring intake meeting checklist.
- Block interview time in advance. Reserve interviewer calendars for the first two weeks of the search.
- Set a feedback deadline. Ask interviewers to submit scores within 24 hours so strong candidates do not accept other offers while you wait.
- Limit rounds. Each extra round adds days and increases the chance a candidate drops out.
- Keep a pipeline for repeat roles. For positions you fill often, stay in touch with past finalists and referrals.
Make vacancy cost part of your hiring reports
Add an estimated weekly vacancy cost to each open requisition and review it with time to fill. Leaders tend to act faster when an open role is shown as "about $1,300 a week" instead of just "still open." Revisit the estimate every month, since the cost often rises the longer coverage lasts.
