The Economics of High-Deductible Health Plans (HDHPs) and HSAs

High-Deductible Health Plans (HDHPs) have surged in popularity across the US due to their lower monthly premiums and their gateway access to a Health Savings Account (HSA). An HSA is an incredibly powerful financial tool with a unique triple-tax advantage: contributions are tax-deductible, funds grow tax-free, and withdrawals for qualified medical expenses are entirely tax-free. For generally healthy individuals with low expected medical utilization, pairing an HDHP with maxed-out HSA contributions allows you to minimize fixed insurance costs while simultaneously building a tax-advantaged investment vehicle for future healthcare needs or retirement.
