Human resources metrics: the KPIs every SME should track
In an SME, decisions about people tend to be made on gut feeling: who performs, why staff leave, or how much it costs to cover an absence. The trouble is that intuition can’t be compared from one quarter to the next, nor justified to management. That is exactly what human resources metrics are for: hard figures that turn people management into something measurable, comparable and actionable. In this guide we look at what they are, what a good KPI should look like, and which indicators are genuinely worth tracking.
What are KPIs in human resources?
A KPI (Key Performance Indicator) is a unit of measurement set for a specific area of the business in order to assess its performance over time. In human resources, these metrics make it possible to quantify things that would otherwise remain a matter of perception: whether the workforce is stable or churns heavily, whether absences spike at certain times of year, or whether investment in training translates into greater productivity.
Measuring is not an end in itself. The value of a KPI lies in what it lets you do with it: spot a problem before it gets worse, benchmark your situation against the sector, and make decisions based on data rather than hunches.
What should a key human resources indicator look like?
Not everything that can be counted deserves to become a KPI. A good indicator must meet four conditions:
- Measurable. It has to be expressible as a number or a percentage. “Improve the atmosphere” is not a KPI; “cut absenteeism below 4%” is.
- Specific. It should refer to a particular aspect, not a fuzzy idea. The tighter the focus, the more useful it is.
- Realistic. The associated target has to be achievable with the company’s resources. Setting impossible goals only breeds frustration.
- Relevant. It must be connected to the goals of the business. Measuring for the sake of measuring eats up time and adds nothing.
To this we should add that a KPI needs a reliable data source. If you calculate absenteeism a different way every month, or rely on someone remembering to log absences in a spreadsheet, the figures won’t be comparable. This is where a people management system makes all the difference: it captures the data automatically and consistently.
Which human resources metrics matter most?
These are the KPIs that add the most value for most Spanish SMEs. You don’t need to track them all: pick the ones that answer the questions worrying you today.
Staff turnover
This measures the movement of people in and out of the workforce over a period. It is calculated by dividing the number of departures by the average headcount and multiplying by 100. High turnover pushes up operating costs (every replacement means recruitment, training and time until the person is fully productive) and usually signals deeper problems: uncompetitive pay, poor management or a lack of growth prospects.
Talent retention
This is the flip side of turnover: it measures how long employees stay, especially in key roles. Losing someone who is hard to replace carries a cost that goes well beyond salary. Tracking average tenure and the retention rate of critical profiles helps you anticipate risks and act before people walk out the door.
Time to hire
This records the number of days that pass from the moment a recruitment process opens until the person joins. A long time to hire leaves vacancies that overload the rest of the team and stall projects. Measuring it lets you spot bottlenecks in the process and adjust your recruitment channels.
Workplace absenteeism
This captures the workforce’s late arrivals, missed days and absences, usually as a percentage of hours not worked against those scheduled. It is one of the most revealing indicators: absenteeism that climbs steadily tends to warn of problems with the working climate, excessive workload or a lack of motivation. To calculate it rigorously you need a reliable record of working hours, which in Spain has also been mandatory since 2019. A time-tracking software captures this data automatically and without friction.
Cost of hire
This adds up everything it costs to bring someone on board: posting job ads, hours spent on selection, initial training and the period until they reach full performance. Putting a figure on it helps you understand the real economic impact of turnover and justify investment in retention, which almost always works out cheaper than replacing talent.
Training and development
This assesses the return on what the company invests in upskilling its team: training hours per employee, the training budget and, above all, its effect on productivity and retention. Well-targeted training is not an expense but one of the most effective levers for keeping people loyal.
From theory to practice
The most common mistake is not choosing the wrong indicators, but having no way to calculate them on an ongoing basis. If the data lives in emails, loose spreadsheets and the memory of your managers, any KPI becomes useless.
The alternative is to centralise your people data in a single tool. With LapsoWork, clock-in records, holidays and absences, working time and shifts are all logged consistently, so most of these metrics calculate themselves and you can check them whenever you need to. Start by tracking two or three KPIs that answer a real problem in your company, and expand from there: it is far better to follow a few well-chosen indicators than to drown in a dashboard full of figures no one ever looks at.
