Why Cost of Vacancy Matters
When a position sits empty, it’s tempting to see it as a budget break. After all, you’re not paying that salary. But this thinking misses what’s actually happening: every vacant day costs your organization money in lost productivity, strained teams, and missed opportunities.
Cost of vacancy (COV) measures the financial impact of an unfilled position. It’s not just a recruiting metric. It’s a business metric that connects talent gaps directly to your bottom line.
Most organizations significantly underestimate these costs. According to Gallup, U.S. businesses lose approximately $1 trillion annually to voluntary turnover alone. And while much of that figure reflects replacement costs, a substantial portion comes from the productivity drain that occurs while positions remain unfilled.
The calculator above is just a starting point for understanding what an open role is costing your organization.
How We Calculate Cost of Vacancy
The formula is straightforward:
Cost of Vacancy = (Annual Salary ÷ 239) × Role Impact Multiplier × Days Vacant
Daily Productivity Value
First, we calculate what an employee contributes per day:
(Annual Salary ÷ 239 working days) × Role Impact Multiplier
Why 239 days? We start with 260 weekdays per year (52 weeks × 5 days) and subtract the actual average time off American workers take based on recent data:
- 8 federal holidays — While there are 11 total federal holidays, U.S. Bureau of Labor Statistics data shows the average worker receives 7.6-8 paid holidays per year
- 10 vacation days — Multiple 2023-2024 studies show workers actually use an average of only 10 vacation days, even though the average policy offers 15 days
- 3 sick days — 2025 workforce data indicates 2-3 sick days is most common, with nearly 25% of workers taking no sick leave at all
This gives us 239 actual working days—a realistic baseline that reflects how much time off American workers actually take, giving you a more accurate foundation for cost of vacancy calculations.
Role Impact Multipliers
Salary alone doesn’t capture an employee’s full business impact. Some roles can be paused or redistributed with limited disruption, while others quietly compound value by unblocking teammates, preventing rework, and keeping decisions moving. When these roles go vacant, the cost extends beyond lost output.
To reflect this, we apply role impact multipliers that estimate how strongly a vacancy affects productivity across the organization.
| Role Impact | Multiplier | What It Reflects |
|---|---|---|
| Low Impact | 1.5× | Work can be redistributed, but vacancies still create coverage gaps, added supervision, slower throughput, and rework |
| Medium Impact | 2.0–2.5× | Independent output with ripple effects across workflows, handoffs, and cycle times |
| High Impact | 3.0× (cap) | Role unblocks others, ensures quality, prevents costly errors, and drives key decisions |
Even roles with lower organizational impact tend to create measurable disruption when vacant, which is why the minimum multiplier is set above 1×.
These multipliers are intentionally conservative. Research commonly places employee value in the 1×–3× salary range, depending on role leverage and impact. For example, Dr. John Sullivan cites research indicating that an individual’s contribution often falls between one and three times salary, and a Harvard-affiliated study found three times salary to be a reasonable estimate for many roles.
To remain broadly applicable and defensible, this model caps the multiplier at 3×, even though some vacancies may exceed that range in practice.
Example Calculation
For a $75,000 medium impact position vacant for 30 days:
- Daily salary value: $75,000 ÷ 239 = $314
- Daily productivity value: $314 × 2.25 = $707
- 30-day vacancy cost: $707 × 30 = $21,210
Note: This example uses rounded figures unlike the calculator above.
Cost of Vacancy by Salary Level
The table below shows estimated vacancy costs at different salary levels, assuming a medium-impact role (2.25x multiplier):
| Annual Salary | Daily Cost | 30-Day Cost | 44-Day Cost |
|---|---|---|---|
| $50,000 | $470 | $14,100 | $20,680 |
| $75,000 | $707 | $21,210 | $31,108 |
| $100,000 | $941 | $28,230 | $41,404 |
| $125,000 | $1,177 | $35,310 | $51,788 |
| $150,000 | $1,413 | $42,390 | $62,172 |
Calculation: Daily cost = (Annual Salary ÷ 239) × 2.25 Total cost = Daily cost × days vacant.
The 44-day column reflects the SHRM median time-to-fill. Every day you shave off that timeline is money back in your pocket.
What This Calculator Doesn’t Include
These estimates are deliberately conservative. Here’s what would make the true impact even higher:
Team Burnout
When someone leaves, the work doesn’t disappear. It lands on everyone else. Gallup research shows employees who frequently work overtime face significantly higher burnout risk. Worse: burned-out employees are 2.6x more likely to leave. One vacancy can trigger another.
Quality and Errors
Stretched teams make more mistakes. Research from Wharton found that in manufacturing, each percentage-point increase in turnover rates increased product defects by 0.74-0.79%, translating to costs in the hundreds of millions.
Customer Impact
For customer-facing roles, vacancies hit service quality directly. Research cited by Forbes found 33% of customers consider switching after just one bad experience.
Opportunity Costs
Projects delayed. Sales not made. Initiatives postponed. These are real costs that don’t show up in any calculator, but they’re often the largest hidden expense of all.
Bottom line: Consider these numbers a floor, not a ceiling.

“But Other Employees Cover the Work”
This is the most common pushback on vacancy cost calculations and it deserves a direct answer.
Yes, when someone leaves, colleagues typically absorb most of the work. But that coverage isn’t free:
Overtime costs money. Whether it shows up as paid overtime or unpaid hours that drive turnover, you’re paying for it.
Other work suffers. When employees cover a vacancy, they’re neglecting their own responsibilities. Something gives.
Quality drops. No one performs at 100% when managing 150% of normal workload.
It’s not sustainable. Short-term coverage works for emergencies. When positions stay open 44+ days, you’re not bridging a gap. You’re operating in a degraded state.
The real question isn’t whether coverage happens. It’s whether that coverage is sustainable, or whether it’s setting you up for the next vacancy.

How to Reduce Your Cost of Vacancy
The most direct lever is time-to-fill. Every day you cut from your hiring timeline reduces total vacancy cost by the daily productivity loss amount.
Build Candidate Pipelines
Proactive sourcing means you’re not starting from zero when a requisition drops. Maintain relationships with strong candidates even when you don’t have open roles.
Streamline Your Process
SHRM data shows screening and interviewing alone average 8-9 days each. Reducing unnecessary rounds or running them in parallel can cut days or weeks from the timeline.
Improve Retention
The cheapest vacancy is the one that never happens. Exit interviews, engagement surveys, and stay interviews can reveal retention risks before they become resignations.
Plan for Transitions
Succession planning isn’t just for executives. Identifying critical roles and developing internal candidates means faster backfills when departures occur.

Frequently Asked Questions
How do you calculate cost of vacancy?
Cost of Vacancy = (Annual Salary ÷ 239 working days) × Role Impact Multiplier × Days Vacant
The multiplier reflects that employees typically generate value beyond their base compensation through team contributions, institutional knowledge, and customer relationships.
How much does an open position cost per day?
Daily vacancy cost = (Annual Salary ÷ 239) × Role Impact Multiplier
The exact amount depends on salary and role impact. Low impact roles (1.5x multiplier) cost less per day; mid to high impact roles (2x-3x multiplier) cost significantly more.
Are the 1.5x-3x multipliers accurate?
Research supports multipliers from 1x to 3x or higher depending on role impact. This range is intentionally conservative. It’s realistic enough to be useful, but not inflated to scare you.
How does time-to-fill affect cost?
Every additional day increases your total cost by the daily productivity loss. The SHRM median time-to-fill is 44 days. Cutting that timeline is the fastest way to reduce vacancy costs.
What’s a good cost of vacancy?
There’s no universal benchmark. The goal is minimizing it relative to your baseline. Track your average over time and aim to reduce it through faster hiring, improved retention, and better workforce planning.
