The HR KPIs worth reviewing are the ones that trigger a decision — employee turnover rate, retention rate by tenure, time to hire, absenteeism rate, training completion, and compliance audit scores. Read them together, benchmark against your own history rather than round numbers, and link each to a business outcome (cost, risk, or productivity) before you set a target. The bigger shift for the year ahead is moving your HR review away from reactive admin and towards workforce strategy — because that’s what the numbers are there to protect.
Your workforce is your most valuable — and often most expensive — asset. HR KPIs provide the practical insights needed to manage it well. As the year concludes, reviewing these metrics reveals where you’re retaining talent, where you’re losing it, how effectively you’re developing people, and whether you’re meeting compliance requirements. Effective HR software with integrated onboarding and workforce analytics provides the foundation for meaningful KPI tracking. This guide covers the essential HR metrics to review, how to interpret your results, and practical strategies for improving workforce outcomes while maintaining compliance with Fair Work and other regulatory requirements.

Essential HR KPIs to review
Tie these numbers back to your performance reviews and KPIs so individual targets ladder up to workforce-wide outcomes. Focus your annual review on these critical workforce metrics:
Employee turnover rate
The percentage of employees who left during the year. Calculate by dividing departures by average headcount. Distinguish between voluntary and involuntary turnover to identify improvement areas. Most Australian industries target 15-20% or lower.
Retention rate by tenure
Track retention separately for different tenure periods. First-year retention is critical — early departures waste hiring and training investment. High retention beyond two years indicates effective engagement measurement and career development.
Time to hire
Average days from job posting to accepted offer. Long hiring times increase vacancy costs and may result in losing candidates to competitors. Track by role type — some positions legitimately take longer to fill.
Training completion rate
Percentage of required training completed on time. Incomplete training creates compliance risks, particularly for mandatory certifications. Track by training type to identify where completion lags.
Compliance audit scores
Results from internal or external HR compliance audits. Track completion of required documentation, policy acknowledgements, and record-keeping requirements. High scores indicate thorough HR processes.
HR file completeness
Percentage of employee files with all required documents. Missing contracts, tax declarations, or certifications create compliance exposure. Regular audits identify gaps for remediation.
Beyond these core six, several supporting metrics round out a complete picture — especially for larger teams. Cost per hire (total recruitment spend divided by hires) reveals how efficiently you fill roles. Absenteeism rate (unplanned absence days as a share of available working days) flags morale and workload issues early. Employee engagement or eNPS, drawn from culture surveys, predicts both performance and future retention. Internal promotion rate shows how well you develop talent from within, and the 90-day quit rate — how many new hires leave in their first three months — is one of the sharpest signals that onboarding or hiring expectations need work.
Leading vs lagging KPIs (and why the mix matters)
A common reason HR reviews feel backward-looking is that most of the headline numbers are lagging indicators — they report what already happened. Turnover rate, absenteeism, and labour cost all tell you the outcome after the fact. They’re essential for measuring results, but by the time they move, the cause is months behind you.
Leading indicators point forward. Engagement scores, time to proficiency for new starters, training completion, and creeping unplanned absences all predict where turnover and cost are heading before they land. A balanced HR dashboard pairs the two: leading metrics to intervene early, lagging metrics to confirm whether the intervention worked.
Pair leading and lagging metrics before you draw conclusions
- Leading (predictive):
Engagement, time to proficiency, training completion, early absence trends — act on these to change the outcome.
- Lagging (retrospective):
Turnover rate, absenteeism, labour cost, compliance scores — use these to confirm whether the change worked.
- Read them together:
A strong lagging result off the back of weak leading signals is fragile; watch the leading indicators to protect it.
Analysing turnover to drive improvement
Turnover rate alone tells you there’s a problem. Deeper analysis reveals what to do about it:
1. Segment by tenure
When do people leave? High turnover in the first 90 days suggests onboarding or job expectation issues. Departures at 1-2 years may indicate limited career progression. Long-tenured departures often signal management or compensation problems.
2. Analyse by department or manager
Compare turnover across teams. Significant variation between departments with similar roles often indicates management effectiveness differences. Some managers consistently retain talent; others consistently lose it. Address the pattern, not just individual departures.
3. Review exit interview themes
Aggregate exit interview feedback to identify patterns. Common themes reveal systemic issues. If multiple people cite scheduling inflexibility, address rostering practices. If compensation appears repeatedly, benchmark your pay rates against market.
4. Calculate turnover costs
Put a dollar value on turnover. Include recruitment costs, training time, productivity loss during vacancy and ramp-up, and administrative processing. Studies suggest replacement costs 50-200% of annual salary. This calculation builds the business case for retention investments.
Compliance KPIs that matter
Compliance failures create legal exposure and damage employee trust. Focus on these compliance-critical metrics:
Contract completion
Every employee needs a signed employment contract or letter. Track the percentage with current, signed contracts on file. Outdated contracts after significant changes also create risk.
Certification currency
For roles requiring certifications (RSA, first aid, working with children), track expiry dates and renewal completion. Expired certifications may invalidate insurance coverage and violate regulations.
Policy acknowledgement
Track acknowledgement of key policies: code of conduct, workplace health and safety, privacy, and anti-discrimination. Signed acknowledgements demonstrate employees were informed of expectations and obligations.
How to choose the right KPIs (not just more of them)
Not every number is a KPI. A useful rule of thumb: a metric is any figure you can report; a KPI is a metric tied to a decision and a target. Average tenure or interview cost are metrics — helpful context, but they don’t change a decision on their own. A good HR KPI meets the SMART test — specific, measurable, attainable, relevant, and time-bound — and it has an owner who acts on it.
A metric earns its place as a KPI when it is:
-
Actionable — poor performance points to a specific, realistic response
-
Owned — someone is accountable for moving it, not just reporting it
-
Aligned — it ladders up to a business outcome (cost, risk, service, or growth)
-
Sparse — you track the vital few, not every number your system can produce
-
Time-bound — it has a review cadence and a target date, not an open-ended aspiration
Setting improvement targets
Use your annual review to establish meaningful HR targets for the coming year:
Focus on high-impact metrics
Prioritise KPIs that most affect your business. If turnover is your biggest cost driver, focus retention targets. If compliance gaps create risk, prioritise documentation completion. Don’t try to improve everything simultaneously.
Set realistic increments
Base targets on current performance plus achievable improvement. Reducing turnover from 25% to 20% is realistic. Targeting 10% may not be achievable in one year. Build momentum through consistent progress.
Link to business outcomes
Connect HR targets to business results. Calculate the cost savings from reduced turnover, the risk reduction from improved compliance, or the productivity gains from better training completion. Business-linked metrics get executive support.
Plan quarterly reviews
Don’t wait until next December to assess progress. Set quarterly checkpoints to track improvement and adjust strategies. Early warning of off-track metrics enables course correction before problems compound.

Frequently asked questions
What are the most important HR KPIs to track?
The most important HR KPIs include employee turnover rate, time to hire, cost per hire, training completion rate, employee satisfaction scores, compliance audit results, absenteeism rate, and retention rate by tenure. Regular performance reviews support many of these by identifying development needs and tracking progress, while HR software helps track them efficiently.
How do you calculate employee turnover rate?
Calculate turnover rate by dividing the number of employees who left during a period by the average number of employees, then multiplying by 100. For example, if 12 employees left during a year with an average headcount of 100, the annual turnover rate is 12%. Australian businesses typically target turnover below 15-20% depending on industry.
What is a good employee retention rate?
A good employee retention rate depends on industry but generally falls between 80-90% annually. Higher retention reduces recruitment costs and preserves organisational knowledge. First-year retention is particularly important, as early departures represent lost investment in hiring and training.
What is the difference between an HR metric and an HR KPI?
Every KPI is a metric, but not every metric is a KPI. A metric is any figure you can measure — average tenure or interview cost, for example. A KPI is a metric tied to a strategic decision and a target, with an owner accountable for moving it. Focus your review on the vital few KPIs that change a decision, and treat the rest as supporting context. Tracking them in HR software keeps the picture consistent.
What are leading and lagging HR KPIs?
Lagging KPIs report outcomes that have already happened — turnover rate, absenteeism, and labour cost. Leading KPIs predict where those outcomes are heading, such as engagement scores, training completion, and time to proficiency for new starters. A balanced dashboard pairs both: leading metrics let you intervene early, and lagging metrics confirm whether the intervention worked. Workforce analytics helps you visualise both together.
How do HR KPIs affect business performance?
HR KPIs directly impact business performance through labour costs, productivity, and compliance risk. High turnover increases recruitment costs (typically 50-200% of annual salary per departure). Low compliance scores create legal exposure, and poor training completion affects service quality. Effective HR management reduces costs while improving operational outcomes.
What HR KPIs indicate compliance risks?
HR KPIs indicating compliance risks include incomplete employee files, expired certifications, overdue training requirements, missing signed contracts, poor record-keeping audit scores, and documentation gaps in termination processes. High rates in these areas signal potential Fair Work or industry-specific compliance issues that centralised, audit-ready HR records help prevent.
How often should HR KPIs be reviewed?
Review HR KPIs monthly for operational metrics like absenteeism and quarterly for strategic metrics like turnover and engagement. Conduct comprehensive annual reviews to assess year-over-year performance and inform workforce planning. Real-time dashboards enable continuous monitoring of compliance-critical metrics.
What causes high employee turnover?
High employee turnover typically results from poor management practices, inadequate compensation, limited career development, poor work-life balance, ineffective onboarding, toxic workplace culture, and misaligned job expectations. Exit interview data and employee surveys help identify the specific causes in your organisation.
How do you improve HR KPI performance?
Improve HR KPI performance by identifying root causes through data analysis, implementing targeted interventions, investing in HR technology for better tracking, training managers on people management, regularly reviewing policies, and benchmarking against industry standards to set realistic improvement targets.
What is the difference between HR KPIs and OKRs?
KPIs monitor the ongoing health of your workforce, while OKRs set time-boxed goals to improve a metric. A KPI you decide to actively move often becomes the baseline for an OKR — see our OKR examples for Australian workplaces for ready-to-adapt objectives and key results.
