Time to Hire vs Time to Fill: Formulas, Benchmarks and Where Screening Loses Days

Time to fill measures how long a job stays open: from the day it is approved or posted to the day a candidate accepts the offer. Time to hire measures how long your process takes with one person: from the day that candidate applies or is sourced to the day they accept. The first tells you about the search; the second tells you about your process, and it is the one you can shorten fastest.

Both numbers are simple to calculate and easy to get wrong, because teams start the clock on different days. This guide gives the formulas, a worked example, recent benchmarks with their caveats, and the places where the first round of a hiring process loses the most days.

What is time to fill?

Time to fill is the number of days between opening a job and filling it. "Opening" usually means the date the requisition was approved or the job was posted; "filling" usually means the date the chosen candidate accepted the offer. Some teams count to the start date instead, which adds notice periods the recruiting team doesn't control.

Time to fill reflects everything about the search: how hard the role is to hire for, how attractive the offer is, how fast the hiring team moves, and how long the job sat before anyone posted it. It is the number a hiring manager feels, because it is how long the seat stays empty.

Formula: time to fill = date the offer was accepted − date the job opened.

What is time to hire?

Time to hire is the number of days between a candidate entering your process and accepting your offer. The start is usually the application date for inbound candidates, or the date a sourced candidate first replied. The end is the date they accepted.

Because it starts with the candidate rather than the job, time to hire strips out the days before your eventual hire even applied. What is left is the speed of your own process: how quickly someone is screened, interviewed, decided on and offered. It is also the number candidates feel. Every day they wait is a day another employer can call them first, which is how slow processes lose good people (more on that in interview no-shows and candidate ghosting).

Formula: time to hire = date the candidate accepted − date the candidate applied (or was sourced).

A worked example

One customer support role, with dates:

• Time to fill: March 2 to April 8 = 37 days.
• Time to hire: March 9 to April 8 = 30 days.

Now look at the gaps inside those 30 days. A full week passed between the application and the first screen, and nine days between the first screen and the hiring manager's interview. The interviews themselves took a few hours. Most of the 30 days were spent waiting for the next step, which is the usual pattern and the most useful thing these numbers can show you.

What are typical benchmarks?

Published benchmarks give a rough sense of scale. Treat them as context, not targets, because each source defines its clock differently.

• Gem's 2025 benchmarks (a vendor report) found time to hire rose from 33 days in 2021 to 41 days in 2024, while interviews per hire rose from 14 to 20 over the same period. Source: Gem, 2025 Recruiting Benchmarks Report.
• Employ's benchmarks (also a vendor report) put average time to fill at 63.5 days in 2025, down from 67.7 days in 2024, while applications per job rose to 257.6. Source: HR Dive on Employ's report, January 2026.
• Employ's January 2026 release reported an average time to hire of 46.2 days and 7.2 days from application to first screen, from data across its customers. Source: Employ, January 7, 2026.

Two caveats before comparing yourself to any of these. First, the definitions differ: one source starts the clock at application, another at sourcing, another at requisition. Second, averages hide the mix: a company hiring mostly hourly roles and one hiring senior engineers will report very different numbers for equally good processes. Your own trend, by role family and quarter, is the benchmark that matters.

Where does the first round lose days?

The first round is where most processes leak time, because it is the step with the most candidates and the most calendar coordination.

The wait before anyone responds

An application sits until a recruiter gets to it. With hundreds of applications per role, that queue grows quickly, and each day in it is a day the candidate keeps looking. On Employ's figures, the average candidate waited 7.2 days between applying and a first screening interview in 2025: about a week before anyone spoke to them.

Scheduling the screen

A 15-minute phone screen can take several emails to book. The recruiter offers times, the candidate is at work, the times pass, new times are offered. Each round trip adds a day or two, and some candidates simply stop replying.

Waiting for the hiring manager

Once a candidate passes the screen, they wait for a slot on the hiring manager's calendar. Without a set expectation, such as feedback within two working days, this gap can be the longest in the process.

Feedback that arrives late

Interviewers who score a candidate days after the interview slow the decision and remember less. A scorecard filled in on the day is faster and more accurate (see the interview scorecard template).

How do you reduce time to hire?

Eight changes that shorten the process without lowering the bar:

1. Measure the gaps, not just the total. Track days from application to first screen, screen to hiring manager, final interview to offer. The longest gap is the first fix.
2. Respond to every application within a day or two, even if only to say what happens next. A quick, clear next step keeps candidates in your process.
3. Remove scheduling from the first round. Let candidates take the first interview when it suits them, rather than when a slot opens. An AI interview the candidate can start at any time, reviewed by a recruiter afterwards, is one way; a one-way recorded screen is another.
4. Ask the hard requirements first. A few well-worded knockout questions flag the obvious mismatches early, so the time goes to people who could do the job.
5. Use a structured first round. The same questions for everyone, scored against the same anchors, make the go/no-go decision quicker and easier to defend. The pre-screening interview questions guide has 50 to choose from.
6. Hold interview slots in advance. Ask hiring managers to block recurring interview times each week for open roles, so a passed screen turns into an interview within days.
7. Set a feedback deadline. Scores and notes within one working day of each interview, and a decision meeting booked before the final round happens.
8. Cut rounds that don't add evidence. If two rounds assess the same competency, merge them. More interviews per hire, as Gem's numbers show, is not the same as better hiring. Our guide to the interview-to-hire ratio shows how to measure it stage by stage.

Shortening time to hire also lowers what each hire costs, because recruiter and hiring-manager hours are part of the bill. The cost per hire guide shows how to count them, and the screening cost calculator works out the recruiter hours your first-round screens take today.

Where does DIO fit?

DIO, Dio's AI interviewer, runs the first-round interview so it no longer needs scheduling. The recruiter shares a link, the candidate takes a structured voice interview in the browser whenever it suits them, usually in about 15 minutes, and the team gets a recording, a transcript and a scorecard in which each competency score quotes the candidate's own words. A person on the team reviews it and makes the decision, so what DIO removes is the wait for a screening slot, not the judgment. Watch how it works.
