A wellbeing campaign can be well attended, well received and still be difficult to justify at budget review. To measure health campaign ROI, employers need more than positive comments after a health day. They need a clear view of who took part, what employees learned or changed, what the programme cost to deliver and which business outcomes it can reasonably influence.
For workplace health initiatives, ROI is rarely a single perfect number. A blood pressure check, a stress-management webinar and a weekly yoga class will not create the same outcomes or operate on the same timescale. The practical goal is to build a proportionate measurement approach that gives HR, People teams and senior leaders enough evidence to make confident decisions.
Start with the outcome you need to influence
Measure against the reason the campaign exists. If the aim is to increase preventative health awareness, participation and health knowledge may be the right primary measures. If the aim is to support a workforce with rising musculoskeletal complaints, movement sessions and posture training should be assessed against comfort, confidence and relevant absence trends.
Avoid setting broad objectives such as “improve wellbeing”. They are difficult to track and can make a useful campaign look vague. A better objective might be: “Give 300 employees convenient access to core health checks over two days, with at least 60% of participants receiving immediate results and signposting.” Another could be: “Improve employees’ confidence in recognising stress and accessing support within three months.”
The outcome should also match your level of control. An employer can provide easy access to screening and education. It cannot promise that every participant will change their lifestyle or that absence will fall immediately. This distinction keeps ROI reporting credible.
Define ROI beyond financial return
The traditional ROI formula is straightforward:
ROI = (financial benefit – programme cost) ÷ programme cost x 100
It is useful where a financial benefit can be estimated with reasonable confidence, such as reduced external provider costs, lower room hire costs, or time saved through a simpler delivery model. But workplace wellbeing also generates value that is not always sensible to convert into pounds straight away.
For most health campaigns, report three connected measures: delivery efficiency, employee reach and meaningful outcomes. Together, they show whether the campaign was practical to run, whether it reached the intended audience and whether it produced a result worth repeating.
A workplace health screening kiosk, for example, can be evaluated through the number of completed checks, cost per participant, time taken per assessment and the proportion of employees who say the check prompted them to consider a next step. The immediate printed results are useful here: employees leave with their own measurements rather than waiting for an appointment or follow-up email.
Establish a baseline before the campaign begins
Without a baseline, it is hard to show movement. Collect only the information needed to assess your objective, and do so before promotion starts where possible.
For engagement, the baseline might be attendance at previous wellbeing activity, the number of employees who have used occupational health support, or a short pulse survey on confidence in managing stress, sleep or physical health. For a screening campaign, you may simply start with the eligible workforce size and expected participation rate.
Use anonymous, aggregated information for employer reporting unless there is a clear, lawful reason to process identifiable health information. Individual results from health screening are personal to the employee. Employers should not use them to make employment decisions. Aggregated usage figures can, however, help identify demand by site, shift pattern or campaign period without exposing individual data.
Keep baseline questions short
A five-question survey is more likely to be completed than a lengthy wellbeing audit. Ask only what will help you judge success. For example, before a resilience webinar, ask employees to rate their confidence in spotting signs of overload and knowing where to seek support. Ask the same questions afterwards and again several weeks later if you need to assess retention.
Track the inputs that affect campaign value
Campaign costs are not limited to the supplier invoice. A useful calculation includes internal time and delivery requirements, particularly when comparing different formats.
Include the cost of the service, venue or space preparation, communications, employee release time where material, administration and any follow-up resources. Then record the practical inputs that can affect uptake: campaign length, number of sites, opening hours, shift coverage and whether appointments were required.
This is where low-friction delivery can have a measurable advantage. An on-site screening kiosk can be placed in a suitable workplace area with power, allowing employees to complete core checks during the working day without individual appointment scheduling. If technicians manage delivery, installation, maintenance and basic user training, the internal coordination requirement is lower than a campaign that depends on HR arranging hundreds of time slots.
That does not mean kiosks suit every objective. A clinical assessment requiring interpretation, individual advice or diagnostic testing needs an appropriately qualified healthcare professional. The right model depends on the depth of assessment required, the workforce profile and the follow-up pathway available.
Measure participation properly, not just footfall
A headline attendance figure can conceal important differences. Track the eligible population, the number of employees reached by communications, registrations where relevant, completed sessions or checks, and repeat participation.
For a multi-site employer, compare participation by location and work pattern. A campaign that performs strongly at head office but misses warehouse, manufacturing or field teams may need different hours, placement or communications rather than a larger budget.
The most useful participation measures include:
- participation rate: completed participants as a percentage of eligible employees
- completion rate: employees who finished the activity after starting it
- cost per participant: total campaign cost divided by completed participants
- representation: whether uptake reflects teams, locations and shift groups
- follow-through: the number of employees accessing a related resource, webinar or support route afterwards
Interpret these figures in context. A 25% participation rate may be excellent for a voluntary programme delivered across dispersed sites, while it may indicate a communications problem in a small office where the activity is available all day.
Capture outcomes at the right level
Health campaigns often work in stages. The first result may be awareness: an employee sees their blood pressure, BMI, pulse, body fat percentage, height and weight and gains a clearer understanding of their current measurements. The next result may be action, such as speaking to a GP, using a nutrition resource, joining a movement class or making a small change to routine.
Do not claim clinical improvement from a one-off event. Instead, ask employees whether the activity gave them useful information, increased their confidence or prompted an intended next step. A voluntary follow-up survey two to six weeks later can show whether that intention turned into action.
For education-based campaigns, test knowledge or confidence before and after the session. For physical wellbeing activity, assess perceived discomfort, energy or movement confidence over a defined period. For mental wellbeing programmes, use carefully worded, non-clinical questions around awareness, confidence to seek help and knowledge of available support.
Where absence, staff turnover or employee assistance programme data is available, review it over a longer period and alongside other changes in the organisation. These are influenced by many factors, including workload, management practice, seasonal illness and organisational change. They should support the story, not be presented as proof that one campaign caused the result.
Turn data into a decision, not a spreadsheet
A useful ROI report should answer three questions: did we reach the people we intended to reach, did the campaign create a meaningful outcome, and should we repeat, adapt or stop it?
Present results in a short format. State the original objective, delivery costs, participation, outcome measures, employee feedback and operational observations. Add one practical recommendation, such as extending access to early and late shifts, placing the kiosk nearer a staff entrance, or pairing screening with a webinar on heart health, sleep or nutrition.
Relaxa can provide anonymised usage data options for workplace screening campaigns, helping employers understand overall uptake while keeping individual results private. Used alongside short employee feedback, this creates a more useful picture than attendance figures alone.
Build measurement into the next campaign
The strongest wellbeing strategies do not wait until year end to ask whether activity was worthwhile. They use each campaign to improve the next one. If employees value instant results but participation is low, review location and communications. If uptake is high but follow-through is weak, provide clearer signposting to appropriate support and learning resources.
A well-measured campaign does more than defend spend. It helps employers make practical choices about where to place time, budget and support so that wellbeing activity remains convenient, relevant and useful to the people it is designed to serve.
