What is Cost of Vacancy?
Cost of vacancy quantifies the revenue and productivity lost for every day a position remains unfilled. Slow hiring doesn't just delay getting help, it actively costs the business money through lost output, overworked teams, and missed opportunities. Plan your hiring timeline with the Hiring Plan Calculator and budget recruitment with the Recruitment Cost Calculator.
The Formula
Daily Vacancy Cost = Annual Revenue per Employee ÷ 365 Total Vacancy Cost = Daily Cost × Days Position is Vacant
Worked Example
A company generates $200,000 revenue per employee. A sales position has been vacant for 45 days.
- Daily vacancy cost = $200,000 ÷ 365 = $548/day
- Total vacancy cost = $548 × 45 = $24,658
- If filled 15 days earlier = $548 × 15 = $8,219 saved
📌 The 45-day vacancy costs $24,658 in lost revenue potential. Investing $3,000 in a recruitment agency to fill the role 15 days faster saves $8,219, a 2.7x return.
Why This Matters
Speed vs cost trade-off
Hiring agencies charge $5,000-15,000 but fill roles 20-30 days faster. When each vacant day costs $548, paying $8,000 for a role filled 20 days earlier saves $10,960 minus the $8,000 fee = $2,960 net saving. Speed pays for itself.
Team impact
Vacancies don't just lose one person's output, they overload remaining team members, causing burnout, errors, and further resignations. A 60-day vacancy can trigger a cascading turnover event that costs 3-5x the original position.
Candidate quality deterioration
Top candidates are off the market within 10 days according to Robert Half research. A hiring process that takes 60+ days systematically loses the best applicants to faster-moving competitors. Shortening time-to-hire from 60 to 30 days significantly improves the quality of the talent pool still available when you make an offer.
Common Mistakes
❌ Waiting for the perfect candidate
A "good enough" candidate hired in 30 days delivers more value than a "perfect" candidate hired in 90 days. The 60-day delay costs $32,877 in lost output. Hire for 80% fit and train the remaining 20%.
❌ Not maintaining a talent pipeline
Starting recruitment from zero when someone leaves means 30-60 days of vacancy. Maintaining relationships with potential candidates through networking and employer branding enables 2-week hires when positions open.
❌ Too many interview rounds
Each additional interview round adds 7-10 days to the hiring timeline. Companies requiring 5+ rounds lose 40% of candidates to process fatigue according to Greenhouse data. Consolidate assessments into 2-3 well-structured rounds to balance thoroughness with speed.
