Calibrating how much clients can safely spend in retirement is a multipronged problem that must account for uncertain life expectancies and market conditions, inflation, the retiree's willingness to vary withdrawals based on portfolio performance, and preferences for lifetime spending versus bequests. In this presentation, Christine Benz will take stock of safe withdrawal rates historically, as well as what fixed income yields and equity valuations suggest is a safe starting withdrawal rate for the future. She'll also delve into why some retirees spend less than they could, and share strategies that advisors can take to give their clients "permission to spend."
