The Total Cost Calculator
The total cost calculator is the most impactful decision support tool. It asks employees to estimate their expected healthcare utilization (number of doctor visits, prescriptions, etc.) and calculates their expected total annual cost — premium plus out-of-pocket — under each plan option. For most employees, this analysis shows that the HDHP is the better financial choice.
Decision Support ROI
IQ Insight
Employers who implement decision support tools during open enrollment consistently see higher HDHP adoption rates, lower adverse selection, and higher employee satisfaction with their plan selection. The ROI is significant: a 10% increase in HDHP adoption for a 500-employee group can save $200,000–$400,000 in annual plan cost.
