How to measure wellbeing program effectiveness in 90 days

Knowing how to measure wellbeing program effectiveness is quickly becoming part of the HR job description. You don't need a year-long project or a data team. You need a baseline taken before you act, a handful of well-chosen metrics, and a second measurement to compare against. Ninety days is enough to give your leadership team a credible first answer.

The pressure is there. The CIPD's 2025 Health and wellbeing at work report found UK absence has climbed to 9.4 days per employee per year, the highest in more than 15 years. It also found that 64% of organisations take steps to identify or reduce stress, but only 50% believe those efforts are effective. In Spain, absence reached 7.2% of contracted hours in the first quarter of 2026, according to Randstad Research. Spending on wellbeing is no longer the hard part. Showing what works is.

Here is a four-step plan.

Step 1: Why do you need a baseline first?

Without a baseline there is no impact to show, only a final snapshot with nothing to compare it to. The baseline captures where you start, before you launch or change an initiative.

Before you measure, agree on three things:

• What you want to improve, and where. "Improve wellbeing" is too broad. "Lower stress risk in the customer service team" is measurable.
• Which groups you will compare. Teams, sites, departments or tenure bands. Company averages hide the differences that matter.
• What a good result looks like. Agreeing the threshold with leadership upfront saves arguments later.

If you can, keep a comparison group where you don't act yet. It helps separate the effect of your initiative from what would have happened anyway.

Most programs that disappoint skip exactly this step. We cover the pattern in why your well-being programs are not working.

Step 2: Which employee wellbeing metrics should you track?

Cross wellbeing with the three KPIs leadership already understands: absence, turnover and productivity. Any one of them tells half a story. Together, and broken down by team, they show where to act.

Absence

Express it as lost hours over contracted hours, so you can compare yourself with market benchmarks. If your system allows it, separate sickness absence from other absence.

Voluntary turnover

Track voluntary leavers only. Dismissals and contract ends are driven far less by how people experience work, and they can blur the picture. Turnover moves slowly, so in a 90-day window treat it as a trend line rather than a result.

Productivity

Don't invent a new metric. Use whatever each area already follows: tickets closed, orders shipped, projects delivered on time. What matters is consistency across measurements.

Wellbeing itself

This is where many companies slip. They track the KPIs but never measure the wellbeing they set out to change. You need a wellbeing indicator by team (for example motivation, resilience, commitment, and stress and burnout risk) plus participation for each round. Low participation means the data doesn't represent the team.

Step 3: How often should you measure, and what happens in those 90 days?

Measure at the start and at the end of the 90 days, with a checkpoint halfway. After that, repeat every three months: four moments a year, two of them aligned with performance reviews, so measurement fits into the HR calendar instead of feeling like one more task.

A realistic first cycle:

• Weeks 1 to 2: baseline. Measure wellbeing and pull the previous three months of KPIs, by team.
• Weeks 3 to 6: act where the data points. Start with one or two priority groups, not the whole company.
• Day 45: checkpoint. Review participation and whether the action is reaching the right people. Adjust if needed.
• Weeks 11 to 13: second measurement. Repeat exactly the same method and compare.

One measurement tells you where you are. Repeated measurement explains what is changing. We go deeper in closing the feedback loop on your HR initiatives.

A word on survey fatigue. If every round is a long questionnaire, participation drops by the second wave and your comparison falls apart. Choose a short method people will repeat, ideally one that gives each person something back, such as their own report. That is why Motional Hub uses a two-minute voice check-in: it is built to be repeated every quarter without wearing people out.

Step 4: How do you present the results to leadership?

Show a few numbers, compared with the baseline and tied to a decision. Leadership doesn't need every chart. They need to know what changed, where, and what you propose next.

A one-page structure that works:

1. Starting point. What you measured, in which groups, and the threshold you agreed.
2. What you did. The initiative, where and for how long.
3. What changed. Wellbeing and KPI trends in the group where you acted, against the comparison group.
4. The cost of doing nothing. An estimate of what absence and turnover cost you, using your own data.
5. Next step. Scale, adjust or stop, with the date of the next measurement.

Be upfront about limits. In 90 days you can show movement and relationships between metrics, not prove cause and effect. Saying so builds credibility. For more on choosing metrics that leadership will act on, read why HR leaders need the right people analytics metrics.

Is your wellbeing plan ready to prove results?

Before you start the cycle, check you have the basics: a defined starting point, chosen metrics, a measurement method people accept, clear confidentiality safeguards and a plan for reporting.
