Plotly Graph
The chart compares annual cost, annual benefit, and net benefit. For longer horizons, it also reflects discounted cumulative values.
Example Data Table
| Scenario | Eligible Employees | Participation | Total Cost | Total Benefit | Net Benefit | ROI |
|---|---|---|---|---|---|---|
| Conservative | 300 | 45% | $54,200 | $81,900 | $27,700 | 51.11% |
| Balanced | 500 | 60% | $101,000 | $176,250 | $75,250 | 74.50% |
| Growth | 900 | 72% | $177,760 | $341,220 | $163,460 | 91.96% |
Formula Used
Participants = Eligible Employees × Participation Rate
Total Annual Cost = Fixed Program Cost + Admin Cost + Other Cost + (Participants × Incentive Cost Per Participant)
Daily Salary Value = Average Annual Salary ÷ Workdays Per Year
Healthcare Savings = Participants × Healthcare Savings Per Participant
Absence Savings = Participants × Absence Days Reduced × Daily Salary Value × Absence Cost Multiplier
Productivity Savings = Participants × Average Salary × Productivity Gain % × Productivity Capture Rate
Retention Savings = Extra Employees Retained × Replacement Cost Per Employee
Adjusted Total Benefit = (Healthcare + Absence + Productivity + Retention) × Effectiveness Factor × Risk Adjustment
Net Benefit = Total Benefit − Total Cost
ROI (%) = (Net Benefit ÷ Total Cost) × 100
Benefit-Cost Ratio = Total Benefit ÷ Total Cost
Payback Period (Months) = Total Cost ÷ (Net Benefit ÷ 12)

FAQs
1. What does this calculator measure?
It estimates the financial return of a wellness initiative by comparing annual program cost against healthcare, absence, productivity, and retention gains.
2. Why include a productivity capture rate?
Not every improvement in focus or energy becomes measurable business value. The capture rate helps convert theoretical improvement into a more realistic savings estimate.
3. What is the participant effectiveness factor?
It adjusts expected benefits for engagement quality. A lower value is useful when completion rates, coaching uptake, or sustained behavior change may be limited.
4. How should I estimate healthcare savings?
Use prior claims data, insurer benchmarks, vendor studies, or pilot results. Conservative inputs usually make the model more credible for internal planning.
5. Can I use this for a multi-year business case?
Yes. Increase the analysis horizon above one year. The model applies discounting so cumulative values reflect present-value logic for longer planning windows.
6. What does payback period mean here?
It shows how many months are needed for net annual gains to recover total annual program cost. Negative net benefit means payback is not reached.
7. Should turnover savings be included?
Yes, when the program supports retention. Replacing employees often carries recruiting, training, vacancy, and productivity losses that can materially affect ROI.
8. Is a high ROI guaranteed after launch?
No. Results depend on participation quality, leadership support, targeted interventions, and accurate measurement. This calculator is best used for scenario planning.
