Recruitment Metrics for Small Businesses: Formulas, Examples and a Free Tracker

You are hiring for one role, and 120 applications have arrived. Over the next few days, you review CVs, send invitations and fit interviews around the work of running the business. There is plenty of activity, but the vacancy is still open.

To move the hire forward, you need to see where the work is waiting and which decisions need your attention.

Recruitment metrics measure the speed, cost, progress and outcomes of your hiring process. They turn the activity around a vacancy into something you can examine: applications assessed, interviews completed, decisions outstanding and hours spent reaching a shortlist.

This guide follows one fictional hiring round from the first CV review to a new employee starting work. Along the way, it explains the formulas, the choices behind them and how to use the results.

You can follow the example in the free recruitment metrics tracker.

All figures in the worked example are fictional teaching data.

Start with the hiring decision you need to make

The most useful recruitment metrics depend on what is holding up your vacancy.

An owner with applications waiting for assessment needs visibility into CV review coverage and delays. Someone receiving completed interviews faster than they can review them needs to measure that queue. If candidates regularly leave screening unfinished, interview completion deserves attention.

Your first recruitment dashboard can therefore stay small. Track how many applications have been assessed, where candidates are progressing, what is waiting and how much employer time the work consumes.

These are all hiring metrics. A measure becomes a recruitment KPI when you select it to monitor a particular goal. For example, the age of your oldest unreviewed application could become a KPI when delayed CV decisions are slowing the hire.

Choose measures that will influence your next action. You can add others as the vacancy progresses.

Follow the applications through screening

Return to the fictional vacancy with 120 valid applications.

By the end of CV assessment, all 120 have received a recorded review. The employer approves 50 candidates for an AI screening interview.

Two recruitment metrics now describe what happened.

CV review coverage is 100%:

120 reviewed applications ÷ 120 valid applications × 100 = 100%

CV-to-invitation conversion is 41.7%:

50 approved invitations ÷ 120 reviewed applications × 100 = 41.7%

Coverage tells you whether applications received attention. Conversion tells you how many progressed after that assessment.

Those measures answer different operational questions. If review coverage were low, the next task would be to examine the unreviewed applications and the time available to assess them. Once coverage is complete, you can examine the criteria and decisions behind progression.

The conversion percentage needs that context. Fifty invitations might reflect a strong applicant group, a broad screening threshold or several other circumstances. Read the evidence behind the decisions before judging the rate.

Watch what happens after the invitation

Of the 50 candidates invited, 45 start their screening interview and 40 complete it.

The invitation-to-completion rate is:

40 completed interviews ÷ 50 invitations × 100 = 80%

The completion rate among candidates who started is:

40 completed interviews ÷ 45 started interviews × 100 = 88.9%

The first figure describes the full step from invitation to completion. The second focuses on what happened after candidates began.

Together, they show two places to investigate. Five invited candidates never started. Another five started without finishing. Before changing the process, examine the recorded reasons, invitation instructions, deadlines, withdrawals and technical interruptions.

In this example, every invitation has a resolved outcome by the reporting cutoff. That matters when calculating a final completion rate. Candidates whose deadlines have not passed still need to be shown as pending.

HireMike Insight Record when screening finishes and when its evidence is reviewed. The time between those events shows the decisions still waiting for an employer's attention.

See how screening changes the human workload

After reviewing the 40 completed screening interviews, the employer advances 12 candidates to human interviews.

The screening-to-human-interview conversion is:

12 candidates advancing ÷ 40 completed screening interviews × 100 = 30%

This tells you how much the screening stage narrowed the group for the next step. To understand whether that narrowing was useful, you need to review the criteria, the evidence and eventually the hiring outcome.

The twelve candidates then attend fifteen human interview meetings because some have an additional round.

That small detail changes how workload should be counted.

There are twelve human-interview candidates and fifteen human interview events. The twelve people are also part of the forty who completed screening, so adding the two candidate counts would count them twice.

By the end of this recruitment round, one person starts employment. The business therefore conducted:

• 12 human-interview candidates per started hire.
• 15 human interview meetings per started hire.

Keep those labels attached to the figures. They describe different demands on the business.

Our interview-to-hire ratio guide and calculator explains these counting choices in more detail.

Put working time beside the candidate counts

Candidate numbers reveal the size of the process. Recorded working time shows the effort involved.

For this fictional vacancy, the business logs:

• 120 person-minutes reviewing CV assessments.
• 160 person-minutes reviewing completed screening results.
• 540 person-minutes conducting human interviews.
• 60 person-minutes in debriefs.

CV and screening-result review total 280 minutes, or 4 hours 40 minutes.

Across all four activities, the recorded effort is 880 minutes, or 14 hours 40 minutes.

Other work, including preparing the role, advertising and administering offers, would need its own record. The figure above covers the activities listed.

Use person-minutes when several employees participate. A thirty-minute interview attended by two business representatives consumes sixty employer person-minutes.

This also helps you evaluate automation accurately. Record the employer's preparation, review and decision time separately from the time a candidate spends in an interview. To establish savings, compare equivalent activities across similar hiring situations.

Keep an eye on the two hiring clocks

While applications move through screening, two time measures help explain how long the vacancy is taking.

Time to fill measures the calendar days from opening the vacancy to having an offer accepted.

Formula: offer acceptance date − vacancy opening date

That follows the requisition-opened-to-offer-accepted definition in SHRM's 2025 recruiting benchmarking report.

Time to hire follows the successful candidate through the process. For an inbound application, calculate it from the date their application arrived to the date they accepted the offer.

Formula: offer acceptance date − application received date

For someone approached directly, record the first contact or identification date and state that definition. SHRM describes time to hire as the period from candidate identification to offer acceptance. SHRM's recruitment metrics guidance

A vacancy may have been open for several weeks before the eventual hire applied. Time to fill captures that longer business wait. Time to hire shows how quickly that person moved through assessment and decisions.

To investigate a delay, look inside the total. Examine the intervals between application and CV assessment, invitation and completion, and completed interview and the next decision.

For a vacancy still open, report its current age separately. Our guide to reducing time to hire covers practical ways to address those waiting periods.

Follow the offers through to an actual start

The employer makes two offers. One candidate accepts and the other declines. The accepted candidate subsequently starts work.

That produces a resolved-offer acceptance rate of 50%:

1 accepted offer ÷ 2 resolved offers × 100 = 50%

For resolved offers, the formula is:

Accepted offers ÷ (accepted offers + declined offers) × 100

The National Association of Colleges and Employers' 2024 professional standards use this calculation for early-talent recruiting and exclude outstanding offers from the real-time rate.

Keep pending offers visible. Record expired or employer-withdrawn offers separately and document how they are treated in your calculations.

In this example, one acceptance and one actual start are recorded as separate events. Maintaining that distinction helps you see whether an accepted candidate went on to join.

The underlying counts matter here. "One of two offers accepted" gives a clearer sense of the evidence than a percentage alone. Two offers provide limited support for a broad conclusion about compensation, candidate experience or the strength of your offer process.

Work out what the recruitment round cost

Once the hiring outcome is recorded, you can calculate cost per hire.

Formula: (internal recruiting costs + external recruiting costs) ÷ number of hires

Include the recruitment costs relevant to your chosen reporting method, such as advertising, agency fees, screening tools and employee recruiting time.

The 2012 ANSI/SHRM cost-per-hire methodology separates those recruitment costs from post-hire salary, training and productivity losses.

Use consistent categories and reporting periods. If you assign a monetary value to an owner's time, document the hourly assumption and distinguish it from cash expenditure.

When a vacancy remains unfilled, report spending so far and leave cost per hire unavailable.

Record where the successful application came from

The completed hire also gives you an outcome for source of hire.

Formula: hires attributed to a source ÷ total hires × 100

Choose a consistent attribution rule, such as the source recorded when the application was submitted.

For a business hiring occasionally, keep the counts visible and build the record over time. One successful applicant tells you where that hire originated. Several comparable recruitment rounds provide more useful evidence about which sources repeatedly produce suitable candidates.

You can also examine which sources produced candidates who reached screening or human interviews, provided the assessment criteria stayed consistent.

Keep measuring after the vacancy is filled

The new employee's first day closes part of the hiring story. Their experience and performance over the following months provide the evidence for quality of hire.

Useful measures might include performance against agreed role expectations, progress towards working independently and contribution to the team.

Choose those expectations and the review period before assessing the result. SHRM notes that quality-of-hire definitions vary, which makes clarity about success especially important. SHRM's quality-of-hire discussion

A screening assessment supplies evidence for a hiring decision. Later job outcomes allow you to examine how well that evidence related to the role.

Our guide to measuring quality of hire provides a fuller method.

Give retention a consistent observation point

Early retention can form part of that later review.

For a 90-day measure, use:

Hires employed on their 90th day ÷ all hires whose 90th day has occurred × 100

Someone who started thirty days ago is still awaiting that milestone. Someone leaving on day one hundred was retained through day ninety.

Review departures in context. The role itself, management, onboarding, working conditions and personal circumstances can all matter when interpreting what happened.

Turn the records into a recruitment dashboard

The free recruitment metrics tracker contains the fictional example alongside blank sheets for your own applications and human interview events.

Start with the Guide tab, then add records to Your applicants and Your interviews. Use a consistent job ID and a unique application ID for each candidate-job application.

On the Metrics tab, choose the role, application date range and reporting cutoff. Mark the group closed only after its application outcomes, invitation deadlines and offers have been resolved.

The file focuses on screening progression, current queues and recorded workload. Measures such as time to fill, retention and full recruitment cost require additional records.

It has capacity for 200 applications and 300 human interview events. Review and extend the calculation ranges before adding more rows.

Keep the current queue visible

A finished recruitment round helps you understand final conversion. An active vacancy requires a view of the work still waiting.

Review unassessed applications, interviews awaiting completion and completed results awaiting a decision. Include older unresolved applications even when they arrived before your latest reporting period.

That gives you something practical to act on today while the final hiring outcome is still developing.

Read the numbers before changing the process

A recruitment metric becomes useful when you understand the circumstances behind it.

Suppose interview completion falls in the next recruitment round. Before changing the questions, compare invitation instructions, deadlines, technical issues and withdrawals.

If more candidates progress to human interviews, examine the assessment decisions and subsequent workload. The change might reflect a stronger applicant group or different screening criteria.

The same care applies to recruitment benchmarks. Before comparing your result with an external figure, check its source, date, population and measurement method. Differences in roles, hiring stages and counting rules can change what a comparison means.

Start by building your own consistent baseline. Show counts beside percentages and compare similar recruitment rounds as the evidence accumulates.

During an active vacancy, a short weekly review can focus on the oldest waiting application, completed interviews awaiting review and the activity consuming the most employer time. Choose one specific adjustment and record it so later results have context.

Candidate feedback can add another perspective. Our candidate experience guide explains how communication and interview design can help you investigate friction in the process.

Where HireMike fits

HireMike assesses CVs against criteria you approve. You choose who progresses to a structured conversational video interview, then review the assessments, recordings and timestamped transcripts before deciding the next step.

Those stages give you clear points at which to record progress: CV assessment, approval to interview, screening completion and evidence review.

Record the corresponding dates, decisions and employer time in your measurement process. As the vacancy moves forward, you can see where work is accumulating and whether a change is helping.

Frequently asked questions

Which recruitment metric should a small business start with?

Start with the measure connected to the hiring work that needs attention. CV review coverage helps when applications are accumulating. Interview completion helps when invited candidates are not finishing screening. Recorded review hours help when assessment is consuming too much working time.

What is a good interview completion rate?

Use a consistently defined baseline for comparable roles and interview formats. Show the number invited, the number completing and which deadlines have passed.

Then examine recorded reasons for non-completion before deciding what to improve.

Can you measure hiring performance when you recruit only a few people?

Yes. Consistent records can expose delayed reviews, repeated scheduling work and unclear decisions even when hiring volume is low.

Use the numbers to understand each recruitment round, with counts beside percentages. Broader conclusions need enough comparable observations to support them.
