Cost of Vacancy Calculator - Quantify the True Cost of Every Unfilled Role

Cost of vacancy (COV) is an HR and finance metric that quantifies the financial impact of a budgeted role remaining unfilled. It captures lost revenue, reduced productivity, overwork costs for remaining staff, and the cost of delayed hiring. Unlike cost per hire, which measures what you spend to fill a role, cost of vacancy measures what the business loses while the role stays open.

The primary formula is: Daily Cost of Vacancy = Annual Revenue Per Employee / Working Days Per Year. Multiply the daily cost by the number of vacancy days to get the total cost. Add revenue attribution adjustments for sales or revenue-generating roles, overwork costs for team members covering the vacancy, and estimated hiring costs for a comprehensive picture. This free Cost of Vacancy Calculator performs all calculations automatically.

Research from SHRM and Gallup indicates that cost of vacancy typically ranges from 0.5x to 2x the annual salary of the unfilled role. Revenue-generating roles such as sales and account management can cost 3x to 5x annual salary due to direct pipeline impact. Support and administrative roles generally fall in the 0.5x to 1x range. Senior technical and specialist roles commonly range from 1.5x to 2x annual salary.

Cost per hire measures the total spend required to fill a role - agency fees, job board spend, recruiter time, assessments, and onboarding. Cost of vacancy measures the financial loss incurred while the role remains unfilled - lost revenue, productivity gaps, overwork costs. Both metrics are important and complementary: cost per hire helps optimise the recruitment process, while cost of vacancy helps justify the urgency and budget to fill a role quickly.

You can calculate the cost of vacancy for multiple open roles, different departments, or projected vacancy periods without any restrictions. Results can be downloaded as a PDF report to share with your leadership team or finance partners.

Vacancy duration has a direct linear relationship with cost of vacancy - every additional day a role remains unfilled adds to the cumulative financial cost. This is why reducing time to hire is one of the highest-return investments a talent acquisition function can make. Use this calculator to project the cost of different vacancy durations and quantify the ROI of faster hiring processes.

For sales, business development, customer success, or other directly revenue-generating roles, use the Revenue Attribution Factor input (default: 1.0). Set it above 1.0 to reflect the outsized revenue impact of that vacancy. For example, an Account Executive responsible for significant annual quota would carry a Revenue Attribution Factor of approximately 2.0 to 3.0 compared to a standard operational role.

The Productivity Factor (default: 0.5) represents the proportion of the vacant role output that existing team members absorb while the position is unfilled. A factor of 0.5 means the team covers approximately 50% of the vacant role output, with 50% lost. A higher factor indicates the team can cover most of the work, typically appropriate for junior or process-driven roles. A lower factor reflects specialist roles where output cannot easily be redistributed.

Yes - for a complete picture of vacancy impact. Onboarding duration represents the period during which a new hire is employed but not yet fully productive. During this ramp-up window, the role is filled on paper but the full productivity value is not yet realised. Adding estimated onboarding duration to the vacancy calculation provides a more accurate total financial impact figure and strengthens the business case for investing in structured onboarding programs.

Cost of vacancy data is one of the most persuasive tools HR and talent acquisition teams have for influencing hiring speed, budget approvals, and recruiter headcount decisions. Present the daily cost figure to hiring managers who are slow to interview or provide feedback. Use total vacancy cost data to justify agency fees, premium job board listings, or additional recruiter capacity. Show finance teams the compounding cost of extended vacancies versus the one-time cost of faster hiring.
