The right HR KPIs prove whether your culture is working by linking how people feel and behave to what the business earns and loses. Here are 12 HR KPIs that do that, with what each one shows, how to measure it and how to present it to your board.
Most HR dashboards track activity: training hours, surveys sent, policies updated. Boards don’t care about activity. They care about outcomes. The HR KPIs below are chosen because each one connects culture to cost, revenue or risk, and because you can move them.

12 HR KPIs that prove culture is working
| HR KPI | What it shows | How to measure it |
|---|---|---|
| 1. Regrettable churn rate | Whether you’re keeping the people you want to keep | Regrettable leavers ÷ average headcount, per year |
| 2. Cost per regrettable leaver | What each of those exits costs | Recruitment + vacancy + ramp-up + lost output |
| 3. 90-day new-hire attrition | Whether hiring and onboarding match reality | Leavers within 90 days ÷ new starters |
| 4. Churn by manager and team | Where culture problems are concentrated | Turnover rate split by line manager |
| 5. Revenue per head | Overall workforce productivity | Revenue ÷ average headcount |
| 6. Burnout risk and error rate | Capacity under strain | Pulse responses on workload, plus quality errors |
| 7. Time to fill | How long roles stay empty | Days from vacancy approved to offer accepted |
| 8. Applicants per vacancy | How attractive you are as an employer | Applications ÷ vacancies advertised |
| 9. Flight-risk prediction | Who might leave before they resign | Signals from engagement and behaviour data |
| 10. Escalated cases | The cost of conflict | Grievances, disciplinaries and tribunal claims |
| 11. Engagement or eNPS, with context | How people feel, explained by why | Regular pulse scores plus comment themes |
| 12. Stability index | How settled your workforce is | Staff with 12+ months’ service ÷ headcount a year ago |
Retention HR KPIs
1. Regrettable churn rate
Overall turnover hides the story. Losing poor performers can be healthy. Losing your best people is not. Track the people you wanted to keep separately, and report it every quarter. For context, average UK staff turnover is around 15 per cent, according to the CIPD.
2. Cost per regrettable leaver
Turn churn into money. Add recruitment fees, the time the seat is empty, the months a replacement takes to reach full productivity and any lost clients or sales. Our employee turnover cost calculator will help. Present it to the board as a single number: “each regrettable leaver costs us £X”.
3. 90-day new-hire attrition
High early attrition usually means the job you advertised isn’t the job people find. It’s one of the clearest culture KPIs because it’s measured so soon after the promise is made.
4. Churn by manager and team
People leave managers as well as companies. Split turnover by line manager and the problem areas usually stand out quickly. Present it carefully, as a support need rather than a league table.
Productivity and capacity KPIs
5. Revenue per head
The simplest link between people and performance. Track it over time and alongside culture KPIs, and look for patterns rather than single-quarter changes.
6. Burnout risk and error rate
Burnout shows up in quality before it shows up in resignations. Gallup found that teams in the bottom quartile for engagement had 41 per cent more quality defects than top-quartile teams (Gallup, 2013). Pair workload questions in your pulse surveys with an operational error measure. Our cost of employee burnout calculator helps you put a price on it.
Attraction KPIs
7. Time to fill and 8. Applicants per vacancy
A strong culture makes hiring easier and faster. If time to fill is rising and applicants per vacancy are falling, word about your culture may be getting out. Present both alongside the daily cost of an empty seat.
Risk KPIs
9. Flight-risk prediction
Exit interviews tell you why people left. Flight-risk signals tell you who might leave next. Changes in engagement, absence and participation often show up well before a resignation. Tools like Wotter can flag these patterns.
10. Escalated cases
Grievances, disciplinaries and tribunal claims are expensive, slow and damaging to morale. A rising trend is often an early sign of poor management or a culture problem in one area.
Engagement and stability KPIs
11. Engagement or eNPS, with context
An engagement score on its own invites the question “so what?”. Always present it with the reasons behind it and a link to another HR KPI, such as churn in the same teams. Our guide to employee engagement explains what the number really measures.
12. Stability index
The share of people who’ve been with you for more than a year. A falling stability index means you’re constantly rebuilding teams, which drags on productivity and culture.
How to choose your starting set of HR KPIs
Don’t try to track all 12 at once. Pick three to five HR KPIs that:
- link directly to a business problem the board already cares about;
- you can measure reliably with the data you have;
- you can realistically move in the next six to twelve months.
A good starting set for most organisations is regrettable churn rate, cost per regrettable leaver, 90-day new-hire attrition and engagement with context. Add more once you’ve shown progress. Our post on people strategy covers how to build these into a wider plan.
Frequently asked questions
What are HR KPIs?
HR KPIs are the key performance indicators HR uses to track how well the organisation attracts, keeps and gets the best from its people, with targets attached.
What is the difference between HR metrics and HR KPIs?
HR metrics are any people measures you track. HR KPIs are the small number you’ve chosen as key indicators, usually with targets and regular reporting.
How do you measure company culture?
Through a mix of outcome measures, such as regrettable churn, new-hire attrition and escalated cases, and regular employee feedback that explains why those numbers are moving.
How many HR KPIs should you track?
Start with three to five that link to business problems and that you can realistically improve. Add more once those are established.
What is a regrettable leaver?
A regrettable leaver is someone the organisation wanted to keep, usually a strong performer or someone with hard-to-replace skills.
Measure what proves culture matters
The best HR KPIs connect culture to money and risk. Track regrettable churn and its cost, watch new-hire attrition and churn by manager, measure strain before it becomes burnout, and always give engagement scores context. Start small, show progress, and build from there.
