Ask three recruiters what their time-to-fill is and you will get three numbers measured three different ways. One counts from the day the hiring manager first mentioned the role. One counts from the day the job went live. One is actually reporting time-to-hire and calling it time-to-fill. None of them are wrong on purpose, but the result is a metric nobody trusts, and a metric nobody trusts is one nobody acts on. This post pins down both definitions, explains what each one is good for, and shows how to read them together.
Two clocks, two start buttons
The simplest way to keep these straight is to notice that they start at different moments and answer different questions.
- Time-to-fill starts when the requisition is approved and opened. It ends when a candidate accepts an offer. It measures how long the business waits for a seat to be filled.
- Time-to-hire starts when the person who eventually gets hired first enters your pipeline (applies, gets sourced, gets referred). It ends when that same person accepts. It measures how fast your process moves a good candidate through.
Say a warehouse supervisor role opens on March 3. Postings go up March 5. The eventual hire applies on March 21, interviews on March 28, and accepts on April 4. Time-to-fill is 32 days. Time-to-hire is 14 days. Both are correct. They just describe different things: one is about the whole search, the other is about your process once the right person shows up.
What time-to-fill tells you
Time-to-fill is the number your operations and finance leaders care about, because an empty seat has a cost. A store manager role sitting open for 60 days means overtime, burned-out assistants, and probably some lost sales. Time-to-fill captures the full cost of the vacancy, including the parts that are not really the recruiter's fault: slow approvals, thin applicant flow, a hiring manager who takes ten days to review resumes.
Because it covers so much, it is a poor diagnostic on its own. A long time-to-fill could mean your sourcing is weak, your market is tight, your compensation is off, or your hiring manager is busy. You need to break it into stages to learn anything. Illustrative numbers from a mid-sized retailer might look like this: 4 days from open to posted, 19 days from posted to first qualified applicant, 9 days in interviews, 3 days to offer acceptance. That story says the problem is applicant flow, not interviewing.
What time-to-hire tells you
Time-to-hire is the recruiter's metric. It strips out the waiting-for-applicants problem and looks purely at how fast the process handles a good candidate. If time-to-hire is 14 days and the strong applicants you are losing tend to accept other offers around day 10, you have found something you can actually fix.
- Watch it per stage. Applied to screened, screened to interview, interview to offer. The slow stage is usually obvious once you look.
- Watch it per hiring manager. One manager who averages 6 days to give feedback will quietly drag the whole department's number.
- Watch it per source. Referrals often move faster because the first screen is already half done.
Measuring both without a spreadsheet
The reason these numbers get muddled is that they are usually assembled by hand at the end of the quarter from memory and a few email timestamps. That is where the definitions drift. The fix is to let the system record the timestamps as work happens. When a requisition is opened, that is a timestamp. When a candidate moves from applied to screened, that is a timestamp. When an offer is accepted, that is another one.
Apex ATS calculates both metrics from those stage transitions automatically, so time-to-fill and time-to-hire show up side by side in the analytics view, broken out by role, department, source, and hiring manager. Nobody has to remember which definition the team agreed on, because the definition lives in the report.
- 01Agree on the start and end events for each metric and write them down once.
- 02Make sure recruiters move candidates between stages promptly, because the timestamps are only as good as the pipeline hygiene.
- 03Review both numbers monthly, by role family, and look at the stage breakdown before drawing conclusions.
- 04Set targets separately. A 30-day time-to-fill and a 12-day time-to-hire are reasonable goals for many hourly and mid-level roles, but your own history is a better baseline than anyone else's benchmark.
Neither metric is better than the other. Time-to-fill tells the business how long it waits. Time-to-hire tells the recruiting team how well it runs. Report them separately, define them once, and let the system keep the clocks.
