Time to Fill Metrics: Improve Hiring Efficiency
Introduction
Efficient and effective recruitment is fundamental to any successful HR strategy. In today’s highly competitive talent landscape, HR professionals must expertly balance speed with candidate quality. Among all recruitment metrics, time to fill stands as a leading indicator of hiring effectiveness, operational efficiency, and organizational competitiveness.
But what exactly is time to fill, and why does it matter? How is it different from metrics like time to hire? How can your organization leverage time to fill metrics to benchmark against industry standards and improve your recruitment strategy?
This guide will walk U.S. HR professionals through every aspect - from understanding the difference between time to hire and time to fill to precise calculations, benchmarking practices, and actionable strategies for acceleration.
What Is Time to Fill?
Time to fill tracks the number of calendar days between a job requisition’s approval and the moment a candidate accepts a job offer. In other words, it measures the entire time required to identify, engage, and secure talent for an open role (Society for Human Resource Management, 2022).
For HR teams, this metric provides key insights into recruitment efficiency. Lengthy time to fill can lead to lost productivity, increased costs, and strain on existing teams. Conversely, an efficient time to fill signals a streamlined, effective hiring process.
Core components measured by time to fill include:
- Job requisition approval date
- Job posting live date
- Periods of screening, interviewing, and assessments
- Offer management up to candidate’s acceptance
Understanding time to fill lays the foundation for optimizing speed and efficiency throughout the recruitment process.
Time to Fill Metrics: Why They Matter
Tracking and analyzing time to fill metrics is essential for understanding recruitment performance and its real impact on business functions. Here are five key reasons why time to fill in recruitment is indispensable:
- Resource Planning: Knowing your average time to fill enables proactive workforce planning, prevents operational disruptions, and ensures stakeholder alignment (LinkedIn Talent Solutions, 2023).
- Cost Control: Longer hiring cycles drive up recruitment costs - including advertising, agency fees, and lost productivity. Organizations with faster time to fill metrics can save between $8,000 and $12,000 per vacancy (Glassdoor Economic Research, 2022).
- Candidate Experience: Efficient hiring timelines enhance your employer brand by signaling organizational agility and responsiveness, making your offers more appealing to top talent.
- Talent Competitiveness: In fast-moving markets, a quick time to fill reduces candidate attrition and allows your offers to reach top talent ahead of competitors.
- Process Optimization: Time to fill metrics spotlight bottlenecks, such as screening delays or slow interview scheduling, pinpointing areas for process improvement (Hinkin & Tracey, 2019).
Robust monitoring of time to fill is an indicator of a mature and forward-thinking HR function.
The Difference Between Time to Fill and Time to Hire
While the terms time to fill and time to hire are sometimes used interchangeably, they represent distinct concepts in recruitment analytics - a difference every HR professional should understand.
- Time to Fill: Measures the period from job requisition approval to candidate offer acceptance. It reflects the complete recruitment timeline for filling a vacancy.
- Time to Hire: Covers only the timeline from when a candidate actively enters your pipeline (application, referral, or sourcing contact) until they accept the offer (Work Institute, 2022).
10 Proven Strategies to Reduce Time-to-Hire and Secure Top Talent
Why does this distinction matter?
Time to fill gauges the speed and effectiveness of your entire recruitment operation - including market search, approvals, and sourcing. Time to hire focuses specifically on the efficiency of your candidate journey post-application.
Optimizing both the time to fill and time to hire metrics equips HR teams to pinpoint and correct inefficiencies at every stage - from sourcing to onboarding.
How to Measure Time to Fill in Recruitment
Improvement starts with accurate measurement. To calculate time to fill, consistently track key process milestones.
Standard formula for calculating time to fill:
Time to Fill = Date candidate accepts offer – Date job requisition is approved
When filling multiple roles, calculate your average time to fill by summing the time to fill for all successfully filled positions and dividing by the number of roles filled within a given period:
Average Time to Fill = (Sum of time to fill for all roles) / (Number of roles filled)
Essential data points:
- Date when job requisition is formally opened/approved
- Date when a candidate formally accepts the offer
For more nuanced insights, segment your time to fill metrics by department, location, job level, and hiring source.
Common measurement pitfalls:
- Using an incorrect start point (such as job posting date, rather than requisition approval)
- Failing to separate contract/temporary roles from permanent positions
- Not accounting for holds, changes, or re-openings in the requisition process
Standardizing your calculation method ensures consistent, actionable metrics across your organization.
Industry Benchmark: What Is a Good Time to Fill?
So what is a good time to fill? Industry-wide, time to fill benchmarks vary based on role complexity, sector, and geography.
According to the Society for Human Resource Management (SHRM), the average time to fill in the United States is 36 days (SHRM, 2022). However, benchmarks differ across roles and industries:
- Tech & Engineering: Average 42 days
- Healthcare & Life Sciences: Average 49 days
- Retail & Customer Service: Average 25 days
LinkedIn’s recent insights confirm these trends, noting that specialized and executive roles often exceed the 40-day mark, while high-volume roles may be filled in under 20 days (LinkedIn Talent Solutions, 2023).
Benchmarking factors to consider:
- Role Complexity: Specialized or senior roles require longer searches.
- Market Region: Hiring urgency and speed can vary by geographic demand.
- Employer Brand: Strong brand reputation can speed up time to fill.
- Recruitment Resources: The size and expertise of your talent acquisition team impacts cycle times.
Best practice: Routinely compare your organization’s time to fill against recognized time to fill benchmarks to set achievable goals and monitor progress.
Factors Influencing Time to Fill
Every organization’s time to fill is shaped by multiple variables:
- Job Market Dynamics: Competition for top talent, unemployment rates, and broader economic forces influence candidate availability and speed to hire (U.S. Bureau of Labor Statistics, 2023).
- Role Complexity: Technical, leadership, or highly specialized positions demand more sourcing and extended assessments.
- Internal Hiring Process: Delays in requisition approval, interview scheduling, or assessment processes can stretch timelines (Hinkin & Tracey, 2019).
- Hiring Manager Engagement: The responsiveness and involvement of hiring managers directly impact recruitment velocity.
- Candidate Experience: Slow communication or unclear timelines prompt drop-offs, requiring restarts and adding days to your metric.
- External Shocks: Unexpected events like offer withdrawals or shifts in market salary expectations can suddenly extend your time to fill.
Identifying and addressing these factors helps HR professionals accelerate hiring, minimize costs, and secure top talent.
