New research indicates that many retirees believe their savings may not last as long as originally expected. Rising healthcare costs, longer life expectancies, and uncertainty around market performance contribute to this concern. Retirees with predictable income sources reported greater confidence, while those relying primarily on portfolio withdrawals expressed higher anxiety about longevity risk. The findings highlight the importance of aligning dependable income with essential expenses and planning for extended retirement horizons. A structured income framework can help reduce the likelihood of accelerating withdrawals during market volatility and improve long-term sustainability.
