Key HR metrics for SMEs: three are enough
You already hold the data. It sits with your payroll provider, inside your contracts and in your accountant's files. Collecting it is not the problem. Reading it is. When it comes to key HR metrics for SMEs, three numbers are enough to start with: turnover, absence and training.
Taken one by one, each tells an incomplete story. Read together, they place your organisation somewhere between what it is today and what your strategy assumes.
📋 The essentials
Three metrics are enough to steer HR in an SME: turnover, absence and training.
A single figure means nothing on its own. It becomes useful compared with itself over time and broken down by team.
Turnover describes the past, absence describes the present, training describes what you are preparing.
A metric does not hand you an answer. It shows you where to ask the right question.
Why three key HR metrics for SMEs are enough
I regularly see the same situation. An SME director builds an ambitious HR dashboard: fifteen rows, several sources, a neat layout. Two quarters later, nobody fills it in. A metric nobody looks at is worth nothing.
Three numbers fit on a single page. They are calculated from data you already own, in about an hour per quarter. That constraint is not a compromise: it is what makes the measurement survive a busy period.
Turnover: what your leavers say about the organisation
Definition: the turnover rate. The number of leavers over a period, divided by the average headcount for that same period, multiplied by one hundred. Four leavers against forty people present on average across the year gives a rate of 10%. |
The overall rate will teach you very little. What matters is the distribution. Three questions are enough:
When do people leave? Departures clustered in the first months point to recruitment or onboarding, not to pay.
Where do they leave from? A single team affected points to line management, not to the whole business.
Who leaves? Experienced people leaving usually signals a lack of prospects rather than a salary problem.
Absence: a signal to interpret, not a verdict
Two companies can report the same absence rate and live two opposite realities. One long isolated incapacity is not the same problem as short repeated absences spread across the whole team. The first is about health and a safe return to work. The second raises questions about workload, organisation and sometimes the relationship with the direct manager.
Securex publishes an annual Belgian absence barometer that gives a national order of magnitude. Use it as a reference point, never as a target: your most useful comparison remains your own figure from last year.
Training: the only metric that talks about tomorrow
Turnover and absence describe what has already happened. Training describes what you are preparing. Two numbers are enough: training days actually taken against those that were planned, and how they are spread across roles.
The gap between plan and reality is usually the most telling. A training plan delivered at half its volume does not mean people refuse to learn. More often, it means nobody arbitrated between training and production.
In Belgium, companies with at least twenty workers must draw up an annual training plan and grant an individual right to five training days on average per year. Below that threshold the obligation falls away, but the question stays exactly the same.
How to read the three metrics together
Metric | What it measures | The question it opens |
Turnover | What the organisation failed to keep | Where and when do departures cluster? |
Absence | Current workload and working conditions | Long and rare absences, or short and repeated ones? |
Training | The skills you are preparing | Who gets trained, on what, and who never does? |
Figures frame the question, they do not replace it. The conversation with your team leaders sharpens what the data signals: that is the approach described in listen to the field before you recruit.
The gap between today's situation and the one your strategy assumes then becomes readable, and it is that gap which sets the priority order for HR actions. This reading comes before structuring your HR processes, it does not replace it.
Frequently asked questions about key HR metrics for SMEs
How often should these metrics be reviewed?
Once a quarter. Monthly tracking mostly produces noise: in a small structure, a single departure moves the rate by several points.
Is a turnover rate of 15% high?
That depends on the sector and the roles involved. The figure on its own settles nothing. What matters is its trend over three years and whether it clusters on one team or one period.
Do I need HR software to start?
No. A spreadsheet and the extracts from your payroll provider cover all three metrics. A tool becomes useful once reading them has become a habit, not before.
What should I do if the figures look bad?
Do not set a numerical target straight away. First find out where the figure concentrates. An overall rate is rarely corrected; a precise cause can be.
Three numbers, one page, an hour per quarter. This is not a dashboard. It is a way of seeing questions coming before they impose themselves on you.
