Employee Wellness Program Statistics (2026)

Eighty-three percent of large US employers that offer health benefits run at least one wellness program, and 48% of private-sector workers have access to one, up from 39% a decade ago. Participation runs at roughly a third. And the two large randomized trials of US workplace wellness programs, at 160 BJ's Wholesale Club sites and at the University of Illinois, found no significant effect on medical spending, absenteeism, tenure or performance after up to three years.

Every page that ranks for this question still quotes a 2010 meta-analysis that found $3.27 in medical savings per dollar spent. The trials that followed, one of them by the same lead author, rule that figure out. This page uses the KFF employer survey, BLS benefits data, the CDC worksite survey, both randomized trials, the RAND and PepsiCo evaluations, and Gallup's wellbeing data, with the sample and date next to every figure, and explains why observational savings keep appearing when experimental ones do not.

How many employers offer wellness programs

KFF's 2025 Employer Health Benefits Survey of 1,862 employers found 83% of large firms with 200 or more workers that offer health benefits provide at least one health and wellness program, meaning smoking cessation, weight management or lifestyle coaching, up from 79% in 2024. Among small firms with 10 to 199 workers the share was 56%, down from 61%. The worker-side measure is the BLS National Compensation Survey, which found 48% of private-industry workers had access to a wellness program in March 2026, against 39% in 2016, 43% in 2023 and 46% in 2025. Access is 50% across all civilian workers and 64% in state and local government.

The CDC's Workplace Health in America survey is the only worksite-level census and is from 2017. It found a steep size gradient, from 39.5% of worksites with 10 to 24 employees to 91.8% of those with 500 or more, and that only 11.8% of worksites offered what the CDC defines as a comprehensive program with all five elements. Most programs are a screening and a newsletter.

What they include, screening and incentives

KFF's 2025 data show 53% of large firms and 35% of small firms give workers the chance to complete a health risk assessment, and 43% and 22% offer biometric screening. Among large firms with an assessment, 53% use incentives or penalties to encourage completion; among those with biometric screening, 62% do. The CDC found 53% of worksites with a program offered participation incentives in 2017, and that 45.1% of worksites offered an employee assistance program, 19.6% a stress-management program and 15.1% depression management. KFF stopped asking about incentive dollar values in 2024, so the last published figure, that 13% of large firms offered more than $500, is from 2017.

Who participates

Participation is the number vendor pages leave out. In the BJ's Wholesale Club trial published in JAMA in 2019, 35.2% of employees at the 20 treatment sites completed at least one wellness module in 18 months and 21.4% completed three or more. Over three years, 28.4% had ever completed a module. In the University of Illinois trial, 56% of the treatment group completed the screening and assessment in year one, with cash rewards of $50 to $650, and only 39% of eligible employees enrolled in the study at all. RAND's 2013 review of employer data found 46% of employees completed a screening where offered, and a fifth or less of those identified for an intervention took part. A third participates in anything; a fifth participates in something sustained.

Who participates matters as much as how many. The Illinois trial found employees who chose to take part had spent $1,384 less on medical care in the year before the program than those who did not. The healthier, cheaper employees join. That single fact explains most of the savings reported by observational studies, which compare participants with non-participants and attribute the difference to the program.

What the randomized trials found

Two large US trials have randomly assigned employees or worksites to a wellness program, which removes the selection problem.

BJ's Wholesale Club. Song and Baicker randomized 160 worksites, 20 to a program and 140 to control, covering 32,974 employees from January 2015. At 18 months, employees at program sites were 8.3 points more likely to report regular exercise and 13.6 points more likely to be actively managing their weight. There was no significant difference in cholesterol, blood pressure, body mass index or glucose. Medical spending was $426 lower per employee, with a confidence interval from $1,266 lower to $415 higher, so not significant. Absenteeism was 2.5% against 2.6%, tenure 306 days against 309, and performance ratings identical. The three-year follow-up in Health Affairs found the exercise and weight-management effects persisted at 5.9 and 6.9 points, and still no significant effect on spending, absenteeism, tenure, performance or any clinical measure.

University of Illinois. Jones, Molitor and Reif randomized 4,834 employees to a program with paid incentives or to control, from August 2016. In the Quarterly Journal of Economics paper, 40 of 42 outcomes showed no significant effect in year one, including total medical spending, every category of use, sick leave, salary, promotion, hours, job satisfaction and gym visits, and the nulls persisted to 30 months. The program did raise the share with a primary care physician by 6.1 points at two years, per the JAMA Internal Medicine follow-up, with no change in blood pressure, body mass index, tobacco use, exercise or mood. The trial's confidence intervals rule out 84% of the effects reported in 112 earlier observational studies, and its 99% interval rules out the 2010 return-on-investment estimate entirely.

A third study is not a trial but is the largest on mental wellbeing programs. Fleming's 2024 analysis of 46,336 workers at 233 UK organizations found participants in resilience training, mindfulness, wellbeing apps, stress management and coaching were no better off than non-participants on any wellbeing measure. It is UK data, and it is cross-sectional, but it covers the interventions employers now buy most.

Where the savings figures came from

The $3.27 in medical savings and $2.73 in absenteeism savings per dollar spent come from Baicker, Cutler and Song's 2010 meta-analysis in Health Affairs of employer studies published before 2010, almost all of which compared participants with non-participants. Baicker then led the BJ's trial that found no such savings. The other sources of the ROI folklore are Johnson & Johnson's self-reported $2.71 per dollar in a 2010 Harvard Business Review article, and RAND's 2013 review of four employers' data, which found a non-significant $157 a year difference for lifestyle program participants over five years and concluded such programs were roughly cost-neutral. RAND's PepsiCo evaluation in 2014 is the one place savings appeared: $30 per member per month overall, almost all from disease management of people already sick, with lifestyle management showing no cost effect. Where savings exist, they come from managing illness, not from promoting wellness.

Wellbeing, engagement and whether employees feel cared for

The case for wellness programs now rests on wellbeing and engagement rather than cost. Gallup's wellbeing indicator put 47% of US employees "thriving" in May 2026, with hybrid workers at 54%, remote at 52% and on-site non-remote-capable at 46%. Globally, 34% were thriving in 2025 and 46% of leaders reported daily stress. Only 24% of US workers strongly agreed their organization cares about their overall wellbeing in Gallup's 2022 data, down from about half at the pandemic peak, and those who did were 69% less likely to be job searching and 71% less likely to report burnout. Thirty-nine percent strongly agreed in 2024 that someone at work cares about them as a person, down from 47% in March 2020. Our employee engagement statistics page covers those items in full, and our workplace stress statistics page covers what employees say actually stresses them.

What the evidence supports

• Behavior change is real and modest. Exercise up 6 to 8 points, weight management up 7 to 14 points, having a primary care physician up 6 points, persisting to three years.
• Clinical and financial effects are undetectable at three years. No trial has found a significant change in biometrics, spending, absenteeism, tenure or performance.
• Participation is a third or less without large incentives, and participants are already healthier and cheaper.
• Disease management of the already-sick saves money; lifestyle promotion does not, in the PepsiCo and RAND data.
• Individual mental wellbeing products show no participant advantage in the largest dataset available.
• Feeling cared for predicts retention and burnout, and that comes from management rather than programs.

Figures to stop using

• "$3.27 saved per $1 spent." A 2010 meta-analysis of observational studies. Ruled out at the 99% level by the Illinois trial.
• "Nearly $6 per $1." $3.27 plus $2.73, added by a vendor. No study reports it.
• "6-to-1 ROI." No source. The nearest real figure is Johnson & Johnson's self-reported $2.71.
• "87% of organizations have a wellness program." No source. KFF's 83% is large firms offering health benefits; BLS's 48% is worker access.
• "52% of US companies have wellness programs." RAND's 2012 estimate for employers with 50 or more staff.
• "Wellness programs cut absenteeism 14% to 19%." The trials found 2.5% against 2.6%.
• "Disengagement costs $10 trillion." Gallup's global engagement model, not a wellness figure.

Key takeaways

• 83% of large US firms offering health benefits have a wellness program, 56% of small firms. 48% of private workers have access, up from 39% in 2016.
• Only 11.8% of worksites offer a comprehensive program. Most consist of a screening and some information.
• Participation is about a third: 35% of BJ's employees completed one module in 18 months and 28% over three years. Participants had spent $1,384 less on care before joining.
• The two US randomized trials found exercise and weight-management gains of 6 to 14 points and no significant effect on biometrics, medical spending, absenteeism, tenure or performance at up to three years.
• The $3.27 per dollar ROI is from a 2010 meta-analysis of observational studies and is ruled out by the Illinois trial at the 99% level.
• Where savings appear in observational data, they come from disease management of the already sick, as in PepsiCo's $30 per member per month, not from lifestyle programs.
• Participants in resilience training, mindfulness and wellbeing apps were no better off than non-participants across 46,336 UK workers.
• Only 24% of US workers strongly agree their employer cares about their wellbeing. Those who do are 71% less likely to report burnout.
