The two most confused recruiting metrics — what each one measures, how to calculate them, what “good” looks like, and why the gap between them is your best hiring diagnostic.
Quick Answer (TL;DR)
Time-to-fill measures the whole process from the day a job requisition is opened to the day a candidate accepts the offer. Time-to-hire measures only the candidate’s journey from when they enter your pipeline to offer acceptance. Time-to-fill is always equal to or longer than time-to-hire, because it includes the pre-candidate phase (approval, job post, sourcing). The gap between time-to-fill and time-to-hire tells you where your bottleneck is.
The one-sentence difference
Time-to-fill = “how long is the seat empty?” (business view). Time-to-hire = “how fast do we move a candidate once we find one?” (recruiter view).
Both metrics end at the same moment — the day a candidate accepts your offer. What separates them is where the clock starts. Time-to-fill starts when the requisition is opened; time-to-hire starts only when a specific candidate enters your pipeline. That single difference is why they constantly get confused, and why mixing them up leads you to fix the wrong bottleneck.
What is Time-to-Fill?
Time-to-fill is the number of calendar days from when a job requisition is opened to when a candidate accepts the offer. It measures the efficiency of your entire hiring funnel.
Time-to-fill is a process-level metric. It captures everything: requisition approval, writing the job description, posting, sourcing, the wait for applications, screening, interviews, decision-making, and the offer. It answers the question leadership actually asks: “How long is this role sitting empty?”
Formula: Time-to-Fill = Offer Acceptance Date − Requisition Open Date
To get your average, sum the time-to-fill for every hire in a period and divide by the number of hires.
What Is Time-to-Hire?
Time-to-hire is the number of days from when a candidate enters your pipeline (applies or is sourced) to when they accept the offer. It measures how efficiently you move candidates through your process.
Time-to-hire is a candidate-level metric. It ignores everything before a candidate showed up and focuses purely on your pipeline speed: screening, interviews, evaluation, and the offer. It answers the recruiter’s question: “Once we find the right person, how quickly can we close them?”
Formula: Time-to-Hire = Offer Acceptance Date − Candidate Entry Date (application or sourced date)
| Dimension | Time-to-Fill | Time-to-Hire |
|---|---|---|
| Clock starts | Requisition opened/approved | Candidate enters pipeline (applies or sourced) |
| Clock ends | Offer accepted | Offer accepted |
| What it measures | The whole hiring process, how long the seat is empty | Pipeline efficiency once a candidate is found |
| Primary audience | Leadership / the business | The recruiting team |
| Typical value | Longer (includes pre-candidate phase) | Shorter (a subset of time-to-fill) |
| Best for diagnosing | Sourcing reach & approval speed | Interview & decision speed |
Why the gap between them matters
Subtract time-to-hire from time-to-fill. A big gap means your bottleneck is sourcing or approvals (top of funnel). A small gap with both numbers high means your interviews and decisions are slow.
The two metrics are most powerful together. The difference between them isolates exactly where time is being lost:
- Large gap (fill ≫ hire): you’re slow to find candidates. The fix is upstream: faster requisition approval, sharper job descriptions, and wider or smarter sourcing.
- Small gap, both high: you find people fine, but move them slowly. The fix is downstream: fewer interview rounds, faster scheduling, quicker decisions.
- Both low: a healthy, efficient funnel: protect it and benchmark against your own trend over time.
Time-to-fill benchmarks (2026)
The most-cited benchmark is ~44 days average time-to-fill in the US (SHRM). Technical roles take longer, 55–62 days (LinkedIn), while high-volume roles can close in under 20 days. Averages hide big variation — segment by role.
According to SHRM’s Talent Acquisition Benchmarking research, the average time-to-fill in the US sits around 44 days (commonly reported in a 36–44 day range). SHRM has noted timelines lengthening — roughly a quarter of organizations reported longer hiring cycles in recent surveys — driven by more interview rounds, skills-based hiring, and competition for specialist talent.
| Dimension | Time-to-Fill | Time-to-Hire |
|---|---|---|
| Clock starts | Requisition opened / approved | Candidate enters pipeline (applies or sourced) |
| Clock ends | Offer accepted | Offer accepted |
| What it measures | Whole hiring process; how long the seat is empty | Pipeline efficiency once a candidate is found |
| Primary audience | Leadership / the business | The recruiting team |
| Typical value | Longer (includes pre-candidate phase) | Shorter (a subset of time-to-fill) |
| Best for diagnosing | Sourcing reach & approval speed | Interview & decision speed |
One methodology warning: many published “time-to-hire” benchmarks are actually time-to-fill. Always check where the clock starts before comparing. And treat national averages as a reference, not a target; the most useful benchmark is your own trend, segmented by role.
The stakes are real: Robert Half’s research suggests that top candidates drop out of the job pursuit within 10 business days after the first interview, and SHRM estimates that an unfilled role costs roughly $4,000–$9,000 per month in lost productivity.
How to Reduce Time-to-Fill and Time-to-Hire?
Attack the metric that’s actually slow: widen sourcing and reuse talent pools to cut time-to-fill; automate screening, scheduling, and communication to cut time-to-hire.
Once the gap tells you where the delay is, the levers are straightforward:
- Reuse your pipeline. A ready talent pool means you don’t source every role from scratch — the single biggest lever on time-to-fill.
- Automate screening. AI screening ranks applicants in minutes instead of days, compressing the largest chunk of time-to-hire.
- Remove scheduling lag. Automated interview scheduling eliminates the back-and-forth that quietly adds days between hiring stages.
- Trim interview rounds. Structured, scorable assessments let you decide with fewer stages — without sacrificing quality of hire.
This is where an AI recruiting platform earns its place. Hirin.ai compresses both metrics at once — its AI agent screens and ranks candidates automatically, schedules interviews without the email tag, and resurfaces past applicants from your database so you source less from scratch.

Key takeaways
- Time-to-fill = requisition open → offer accepted (whole process).
- Time-to-hire = candidate enters pipeline → offer accepted (pipeline speed).
- Time-to-fill is always equal to or longer than time-to-hire.
- The gap between them pinpoints your bottleneck: sourcing/approvals vs. interviews/decisions.
- Benchmark: ~44 days average time-to-fill (SHRM); segment by role and track your own trend.
Frequently Asked Questions
What is the difference between time-to-fill and time-to-hire?
Time-to-fill measures the whole hiring process — from the day a requisition is opened to the day a candidate accepts the offer. Time-to-hire measures only the candidate’s journey — from when they enter your pipeline to offer acceptance. Both end at offer acceptance, but time-to-fill starts earlier, so it is always equal to or longer than time-to-hire.
How do you calculate time-to-fill and time-to-hire?
Time-to-Fill = Offer Acceptance Date minus Requisition Open Date. Time-to-Hire = Offer Acceptance Date minus the date the candidate entered your pipeline (applied or was sourced). For averages, sum the values for all hires in a period and divide by the number of hires.
What is a good time-to-fill?
The most-cited benchmark is around 44 days on average in the US (SHRM), and many teams target 45 days or less. It varies heavily by role: technical and engineering roles often run 55–62 days, while high-volume roles can close in under 20 days. Compare against your own trend, segmented by role, rather than a single national average.
Can time-to-hire be longer than time-to-fill?
No. Time-to-fill always equals or exceeds time-to-hire because it includes the pre-candidate phase — requisition approval, job posting, and sourcing — that happens before any candidate enters the pipeline.
Which metric should recruiters track?
Track both. Time-to-fill shows the business how long roles stay open; time-to-hire shows the recruiting team’s pipeline efficiency. The gap between them is the most useful signal: a large gap points to sourcing or approval delays, while two similarly high numbers point to slow interviews and decisions.
How can I reduce time-to-fill and time-to-hire?
Cut time-to-fill by reusing talent pools and widening sourcing so you don’t start every search from zero. Cut time-to-hire by automating candidate screening, interview scheduling, and communication, and by trimming unnecessary interview rounds. AI recruiting tools can compress screening from days to minutes and remove scheduling lag between stages.
