So, firstly I would say this is exactly the right question to ask. If someone wants you to spend money on wellbeing, "does it actually work?" is precisely what a good finance brain should want to know. And you should not accept a fluffy answer.
BLUF: the honest answer is yes, but not automatically. Well-run wellbeing pays back several times over. Badly-run wellbeing pays back nothing. The difference is not the size of the budget. It is the design.
The headline numbers, honestly
Universal, well-supported wellbeing programmes have been shown to return around £6 for every £1 spent, with more targeted programmes returning a little less. Broader estimates for good programmes tend to land somewhere between £3 and £6 back for every £1 in.
That being said, I want to be straight with you. Those are averages of the programmes that work. They are not a promise that any wellbeing spend returns six-fold. It does not.
Why some pay back and some do not
The dividing line is almost always the same thing: whether people actually take part.
You cannot get a return on something nobody uses. A passive perk sitting unopened returns roughly zero, no matter how good it looked in the brochure. A coached, participative programme that people genuinely engage with is where the multiples come from.
So what that means is: engagement is not a nice-to-have. It is the entire mechanism. Get that wrong and the ROI conversation is over before it starts.
Where the return actually comes from
It is not magic. It is measurable capacity coming back:
- Recovered presenteeism. The big one. People running at 90% instead of 70%.
- Fewer sick days. Fitter people simply get ill less often.
- Better retention. People stay where they feel looked after, and replacing them is expensive.
What to demand before you spend
Here's what to do:
- Ask for outcomes, not sign-ups. A sign-up sheet is not a result.
- Ask to see the model. A credible partner shows you the assumptions, not a guaranteed number.
- Start with a pilot. Prove it on a group before you scale it.
The key takeaway
Wellbeing pays back when people actually take part. So the real question is not "what is the ROI". It is "what will make my people take part", because that is the thing that drives the ROI.
