Time to Fill: Formula, Metrics & How to Reduce It

• Time to fill measures the number of days between the approval of a job opening and the candidate signing the employment contract. This makes it a key metric for assessing the efficiency of the overall recruiting process.
• Time to fill is often confused with time to hire or the two terms are used interchangeably, even though they measure different stages of the hiring process.
• A high time to fill can indicate inefficient processes, unclear job requirements, or a lack of transparency around organizational data.
• The ideal average time to fill varies considerably depending on the industry and position, which is why a single benchmark is rarely meaningful.
• Reliable, up-to-date organizational data is essential for reducing time to fill sustainably.
• In addition to improving internal processes, technology such as up-to-date org charts and skills overviews can play an important role in shortening the hiring process.

Every open position costs an organization money. Existing teams may face additional workloads, projects can be delayed, and potential revenue may be lost. Time to fill measures how long this situation lasts. It not only shows how quickly an organization fills open positions but also how effectively recruiting, business departments, and the wider organization work together.

This article explains what time to fill means, how to calculate time to fill, how it differs from related recruiting metrics such as time to hire and time to offer, what typically causes a high time to fill, and how organizations can reduce it sustainably.

Time to fill measures the period between the point at which a job opening is internally approved and the day the new employee officially starts the role or signs the employment contract. It therefore indicates how long a vacancy remains unfilled overall, including internal coordination, the job posting, the selection process, and contract negotiations.

For organizations, time to fill is much more than just a recruiting statistic. It shows how smoothly processes between business departments, HR, and managers work together. Measuring the metric over a longer period can also reveal seasonal fluctuations, structural bottlenecks, or recurring delays in specific departments.

The time to fill formula is straightforward:

Time to Fill = Date the Contract Is Signed − Date the Job Opening Is Approved

In practice, time to fill is usually measured in calendar days. Organizations can calculate the average time to fill over a defined period, such as a quarter or fiscal year, to compare different roles, departments, or locations.

For meaningful analysis, organizations should not only calculate time to fill across the entire company. Breaking the metric down into more granular categories can provide much more useful insights, for example by:

• Department or function, such as IT, sales, or production
• Seniority level, such as entry-level, professional, or executive roles
• Location or region
• Recruiting channel, such as active sourcing, direct outreach, or unsolicited applications

This level of detail helps identify the actual causes of an above-average time to fill rather than relying on an organization-wide average that may hide individual outliers.

Time to fill vs. time to hire is an important distinction. Although the terms are often used interchangeably, they measure different stages of the recruiting process:

• Time to fill starts when the job opening is internally approved, before the job is posted.
• Time to hire starts when a candidate applies and ends when the candidate signs the employment contract.

Time to fill is therefore the broader metric because it also includes internal lead times, such as management approval or the creation of the job requirements.

Understanding the difference between time to hire and time to fill provides a much more accurate picture of where time is actually being lost in the recruiting process: during internal approval, while the job is open, or during the candidate selection process.

Another recruiting metric that is often overlooked is time to offer. It measures the time until a specific job offer is made to a candidate and therefore ends earlier than time to fill.

Comparing the two metrics reveals how much time passes between making an offer and the candidate signing the employment contract. Delays at this stage can result from contract negotiations, notice periods with a previous employer, or internal coordination on the organization’s side.

A significant gap between time to offer and time to fill can therefore indicate friction during the final stage of the hiring process.

A short time to fill can provide a competitive advantage in most industries:

• More efficient recruiting processes: The shorter the time to fill, the more smoothly internal coordination and selection processes are likely to operate.
• Reduced productivity losses: Every day a position remains unfilled can increase workloads for existing teams and create knowledge or capacity gaps.
• Better access to qualified candidates: Strong candidates are often only available for a limited period. A slow hiring process increases the risk of losing them to another employer.
• Positive candidate experience: A fast and transparent process helps create a positive impression of the organization before a new employee even starts.
• Lower costs: Long vacancies create indirect costs, ranging from lost revenue to overtime for existing employees. Reducing time to fill can help minimize these costs.

In practice, an above-average time to fill can often be traced back to a small number of recurring issues:

• Unclear or delayed internal approvals: Without a transparent overview of open positions and budgets, delays can occur before the recruiting process has even started.
• Unclear job requirements: If the responsibilities and required skills for a position are not clearly defined, finding suitable candidates can take considerably longer.
• Too many decision-making stages: Multi-stage approval processes involving numerous stakeholders can slow down decisions, particularly toward the end of the hiring process.
• Poor coordination between HR and business departments: When managers and HR teams are not working from the same data, misunderstandings about requirements and priorities can arise.
• Lack of market transparency: Without current information on salary levels or candidate availability within a particular industry, the recruiting process can take unnecessarily long.

There is no universal benchmark for a good average time to fill. The number of days required to fill a position can vary significantly depending on several factors:

• Industry: Roles in high-demand fields such as IT or healthcare generally take longer to fill than positions in industries with larger talent pools.
• Role and seniority: Executive roles and highly specialized positions naturally tend to require more time to fill than entry-level positions.
• Company size and structure: Complex approval processes in large organizations can further increase time to fill.
• Regional labor market: In regions experiencing skills shortages, the average time to fill may increase regardless of the efficiency of internal recruiting processes.

Meaningful comparisons should therefore be made within the same industry and seniority level rather than using a single company-wide benchmark. Organizations assessing their own time to fill should consider industry-specific reference values and track their internal development over several quarters instead of relying on one external benchmark.

One of the most common yet less obvious causes of a high time to fill lies not within recruiting itself, but within the organization behind it. If it is unclear which position in the org chart is becoming vacant, which skills already exist within the team, or how a new role fits into the organizational structure, delays can occur before the recruiting process even begins.

An up-to-date and reliable org chart provides clarity. Managers and HR teams can immediately see where there is an actual need, how responsibilities are distributed, and which requirements apply to the open position.

High-quality organizational data and a consistent view of the organization are therefore not merely HR concerns. They can directly contribute to reducing time to fill.

Reducing time to fill sustainably requires a combination of organizational and technological measures:

• Establish standardized approval processes with clearly defined responsibilities and deadlines.
• Define job requirements early and in close collaboration with the relevant business department.
• Use up-to-date organizational data to provide transparency around open positions, reporting lines, and skills gaps.
• Regularly analyze recruiting and HR metrics to identify bottlenecks early and take targeted action.
• Improve communication between HR, managers, and candidates so that decisions can be made quickly.

With Ingentis org.manager, organizations gain an up-to-date, consistent view of their organizational structure at any time.

Open positions, existing skills, and responsibilities can be visualized transparently in the org chart. This enables managers and HR teams to identify vacancies and job requirements early and make approval decisions based on reliable organizational data.

As a result, organizations can reduce the internal delays that often occur at the beginning of a long time to fill.
