Recruiting generates a lot of numbers. The hard part is knowing which ones change how you hire. A few metrics do most of the work: time to fill, time to hire, cost per hire, quality of hire, offer acceptance rate, and applicants per hire. Add source of hire, interview-to-hire ratio, and candidate experience and you have a clear view of your pipeline.
This guide defines each metric in plain terms and gives a benchmark you can quote. For every one you get a definition, how to measure it, and why it matters. We use the ANSI/SHRM standard and SHRM benchmark figures where they exist, and we are honest about which metrics are easy to track and which ones are not. If part of your slowdown is the manual work of preparing candidate CVs, RefineCV can format them into your branded template in seconds, though the real gains come from measuring the right things.
Key takeaways
- On SHRM benchmarks, the average cost per hire is $4,129 and the average time to fill is 42 days.
- Time to fill and time to hire sound similar but measure different windows. Track both.
- A good offer acceptance rate is around 91%, the SHRM average, with a median of 96%.
- Applicants per hire shows the screening load behind each role, so track your own number to catch weak sourcing or a filtering bottleneck.
- Quality of hire is the most important metric and the hardest to measure. SHRM found only about 20% of firms track it in 2025.
Recruitment metrics at a glance
Here are the metrics worth tracking, each in one line, with a benchmark you can quote. The deep dives below add the formula and why each one matters.
| Metric | What it measures | Benchmark |
|---|---|---|
| Time to fill | Calendar days from a job opening to offer accepted | About 42 days on average (SHRM) |
| Time to hire | Days from a candidate applying to accepting | Shorter than time to fill (e.g. 10 vs 30 days) |
| Cost per hire | Internal plus external recruiting cost, divided by hires | About $4,129 on average (SHRM) |
| Quality of hire | Whether a hire has the right skills, performs, and fits | Only about 20% of firms measure it (SHRM, 2025) |
| Offer acceptance rate | Offers accepted, divided by offers extended | About 91% on average (SHRM) |
| Applicants per hire | Applicants received, divided by hires | Varies; track your own |
| Interview-to-hire ratio | Interviews conducted, divided by hires | Varies; track your own |
| Source of hire | The channel each hire came from | Varies; track by channel |
Why metrics matter
Metrics turn hiring from guesswork into something you can manage. If you do not know how long a role takes to fill or what each hire costs, you cannot spot bottlenecks, justify budget, or tell a good process from a slow one. The right metrics show you where candidates drop off, where money goes, and whether the people you hire actually work out.
The danger is measuring the wrong things or measuring them inconsistently. A number that is easy to collect is not always the number that matters. Quality of hire is a good example. It is widely seen as the most important metric, yet SHRM's 2025 Recruiting Benchmarking Report found that only about 20% of organisations actually measure it, in part because there is no agreed definition. Knowing which metrics to trust, and how much, is the point.
The metrics that matter, defined
1. Time to Fill
The number of days from when a job requisition is opened until the candidate accepts the offer. SHRM counts this in calendar days, including weekends and holidays. The SHRM benchmark average is about 42 days.
How to measure: Time to Fill = Date offer is accepted minus Date the requisition was opened. Count every calendar day in between, not just working days. SHRM's Human Capital Benchmarking Report put the average at 42 days.
Why it matters: It tells you how long roles sit open and where your process drags. A long time to fill can cost you top candidates, since the best people often move fast and accept other offers.
2. Time to Hire
The number of days between a candidate applying for a job and that same candidate accepting the offer. It covers only the candidate-pipeline portion of hiring, not the time the requisition sat open before anyone applied.
How to measure: Time to Hire = Date of offer acceptance minus Date of application, for the hired candidate. For example, a requisition opened on 1 January, an application on 21 January, and acceptance on 31 January produces a time to fill of 30 days but a time to hire of only 10 days.
Why it matters: It isolates how fast your team moves once a candidate is in the funnel. Because it strips out the pre-application waiting period, it is a cleaner read on interview scheduling, decisions, and offer speed than time to fill alone.
3. Cost per Hire
The average amount you spend to make one hire, combining internal and external recruiting costs. This is formalised in the ANSI/SHRM 06001.2012 standard, set by SHRM and ANSI in 2012. The SHRM benchmark average is $4,129.
How to measure: Cost per Hire = (Total Internal Recruiting Costs + Total External Recruiting Costs) / Total Number of Hires. Internal costs include items like prorated recruiter salaries and talent acquisition system costs. External costs include advertising, agency or RPO fees, background checks, recruiting technology, and travel. SHRM's Human Capital Benchmarking Report, using fiscal year 2015 data from a random sample of 2,048 members, found an average cost per hire of $4,129.
Why it matters: It shows where your recruiting budget goes and lets you compare channels, teams, and time periods. Using the standard formula keeps your numbers consistent and comparable instead of guessing what to include.
4. Quality of Hire
A measure of whether a new hire has the right skills, performs at a high level, and is a good cultural addition. It is widely regarded as the most important recruiting metric and the hardest to measure.
How to measure: There is no single agreed formula. SHRM's 2025 Recruiting Benchmarking Report found that only about 20% of organisations measure quality of hire at all. Among those that do, the most common measures are performance appraisal scores and retention rates, often combined with qualitative manager or peer assessments.
Why it matters: It is the metric that connects recruiting to business results, since speed and cost mean little if the hire does not work out. Be honest about its limits. It is the most important metric and the hardest one to pin down, so treat your number as a directional signal, not a precise score.
5. Offer Acceptance Rate
The percentage of job offers that candidates accept out of all offers you extend. The SHRM benchmark average is 91%, with a median of 96%.
How to measure: Offer Acceptance Rate = (Number of job offers accepted / Number of total offers extended) x 100. SHRM's Talent Acquisition Benchmarking Report put the average at 91% and the median at 96%.
Why it matters: A low rate signals problems with pay, timing, the candidate experience, or how you sell the role. A high rate means your offers land and your earlier stages are setting expectations well.
6. Interview-to-Hire Ratio
The number of interviews conducted relative to the number of hires made within a set timeframe. It shows how many interviews you typically need to secure one hire.
How to measure: Interview to Hire Ratio = Total number of interviews / Total number of hires, over a chosen period.
Why it matters: It indicates how selective your process is and how much interviewer time each hire consumes. A high ratio can mean weak shortlisting upstream or interviewers who are hard to satisfy, both of which slow hiring and raise cost.
7. Source of Hire
The channel that produced each hired candidate, such as job boards, referrals, agencies, or direct sourcing.
How to measure: Tag every hire with the channel that first brought the candidate in, then calculate the share of hires from each source. Pair it with cost per hire by channel to see which sources are worth the spend.
Why it matters: It tells you where your best candidates come from so you can put budget and effort behind channels that work and drop ones that do not. Without it, spending decisions are blind.
8. Candidate Experience
How candidates perceive your hiring process, from application through to the final decision, including communication, speed, and respect.
How to measure: Collect candidate feedback through short surveys at key stages or after the process ends, and track ratings or net promoter style scores over time. Read it alongside offer acceptance rate, since a poor experience often shows up as declined offers.
Why it matters: Candidates talk, and a bad process damages your employer brand and your pipeline. A strong experience helps offers get accepted and keeps rejected candidates open to future roles.
9. Applicants per Hire
The number of applicants it takes, on average, to make one hire. It is the clearest read on how much volume your funnel has to process for each role you fill.
How to measure: Applicants per Hire = Total applicants received / Total hires made, over a chosen period. The figure varies widely by industry and role, so track your own number over time rather than chasing a benchmark.
Why it matters: It shows the screening load behind every hire. Very low volume can mean a narrow posting or weak sourcing. Very high volume raises the cost of screening and makes fast, accurate early filtering the thing to watch, since most applicants are rejected before anyone speaks to them.
Want to dig into a single metric? See our guides to calculating cost per hire, measuring quality of hire, time to hire versus time to fill, and source of hire.
Do this
- Track time to fill and time to hire together, since they measure different windows of your process.
- Use the ANSI/SHRM cost-per-hire formula so your numbers stay consistent and comparable over time.
- Define quality of hire in writing before you measure it, and combine performance, retention, ramp-up, and manager feedback.
- Break source of hire down by channel and pair it with cost per hire to guide spend.
- Read offer acceptance rate alongside candidate experience to find why offers get declined.
- Count calendar days, including weekends and holidays, when measuring time to fill.
- Review metrics together as a set rather than chasing one number in isolation.
Common mistakes to avoid
Treating time to fill and time to hire as the same thing
They measure different windows. Time to fill runs from when the requisition opens to offer acceptance. Time to hire runs from application to acceptance. For the same role you can have a 30-day time to fill alongside a 10-day time to hire. Mix them up and you will misread where the delay actually is.
Inventing your own cost-per-hire formula
If everyone includes different costs, your numbers stop being comparable. The ANSI/SHRM standard exists so you count the same internal and external costs every time. Skip it and you cannot trust a trend or benchmark against anything.
Pretending quality of hire is a precise score
Quality of hire is hard to measure, and SHRM found only about 20% of organisations track it at all in 2025, partly because there is no agreed definition. Treat any single quality-of-hire number as a directional signal, not an exact figure, and back it with qualitative manager and peer input.
Optimising only for speed and cost
Fast and cheap hiring looks good on a dashboard but means nothing if the hires do not perform or do not stay. Speed and cost metrics need a quality and retention check beside them, or you will reward the wrong behaviour.
Ignoring the candidate side of the funnel
Offer acceptance rate and candidate experience reveal why good candidates walk away. If you only watch internal efficiency metrics, you miss the reasons your best offers get declined and your brand quietly erodes.
Collecting metrics you never act on
A number that is easy to collect is not always the number that matters. Source of hire, for example, is only useful if you actually shift budget toward the channels that produce hires. Metrics with no decision attached are just noise.
Frequently asked questions
What is the difference between time to fill and time to hire?
Time to fill measures the full window from when a job requisition is opened to when a candidate accepts the offer, counted in calendar days. Time to hire measures only from when a candidate applies to when they accept. For the same role you might see a 30-day time to fill but a 10-day time to hire. Time to hire isolates how fast your team moves once a candidate is in the pipeline.
How do I calculate cost per hire?
Use the ANSI/SHRM formula. Cost per hire equals total internal recruiting costs plus total external recruiting costs, divided by total number of hires. Internal costs include items like prorated recruiter salaries and talent acquisition system costs. External costs include advertising, agency fees, background checks, recruiting technology, and travel. SHRM and ANSI formalised this standard in 2012 so the number stays comparable.
What is the average cost per hire?
SHRM's Human Capital Benchmarking Report found an average cost per hire of $4,129, using fiscal year 2015 data from a random sample of 2,048 SHRM members. The same report put the average time to fill at 42 days. Treat both as reference points rather than targets, since they vary widely by role, industry, and channel. Your own consistent number over time is more useful than any single benchmark.
Why is quality of hire so hard to measure?
Quality of hire is widely seen as the most important recruiting metric, yet SHRM's 2025 Recruiting Benchmarking Report found that only about 20% of organisations measure it, partly because there is no agreed definition. Common measures include performance appraisal scores and retention rates, often combined with manager or peer assessments. Because it blends hard data and judgement, treat any single score as a directional signal rather than an exact measure.
What is a good offer acceptance rate?
A good offer acceptance rate is around 91%, which is the average in SHRM's Talent Acquisition Benchmarking Report; the median is 96%. If your rate sits well below 90%, look at your pay, your timing, and the candidate experience, since those are the usual reasons candidates decline. Offer acceptance rate is the number of offers accepted divided by the total offers extended, times 100.
How many applicants does it take to make one hire?
It varies widely by industry, role, and how heavily a job is advertised, so there is no single reliable benchmark. The useful move is to calculate your own number and track it over time. Applicants per hire equals the total applicants received divided by the total hires made.
Which recruiting metric matters most?
Quality of hire is widely seen as the most important, since it connects recruiting to actual business results. The catch is that it is the hardest to measure, and SHRM found only about 20% of organisations track it in 2025. In practice, the most useful approach is to read several metrics together: quality of hire for outcomes, time to fill and time to hire for speed, and cost per hire for efficiency.
How faster, cleaner CVs improve these metrics
Some of these metrics turn on how quickly and how well you present candidates to clients. Time to fill and time to hire both include a manual step that is easy to overlook: reformatting a candidate's CV into your template before you can submit it. Cut that step down and you shave time off both.
Presentation matters too. A clean, consistent, branded CV supports offer acceptance and a good candidate and client experience, because a professional submission reflects well on the candidate and on your agency. The agencies that submit fast, tidy CVs stand out.
This is the one step RefineCV removes. It turns a messy CV into a branded, client-ready PDF in your template in seconds, so your team spends less time formatting and more time filling roles. You can start free with 10 CVs, no credit card, then pay $0.40 per CV or $50 a month for 200 on Pro.
The bottom line
The metrics that matter share one trait. They change a decision. Time to fill and time to hire show you where the process slows. Cost per hire shows where the money goes. Offer acceptance rate and candidate experience explain why good candidates stay or leave. And quality of hire, despite being hard to measure, keeps you honest about whether any of it is working.
Pick a small set, define each one clearly, and measure it the same way every time. Read them as a group rather than chasing a single number. The real gains come from watching the right metrics and acting on what they tell you.
