“I really don’t know, Ann,” replied Steve after I asked him for his approximate monthly or annual expenses. Like many other clients, Steve and Jenn were wondering if they could afford to retire. They were mentally ready, but wanted to be sure they wouldn’t outlive their money while maintaining their quality of life. Steve had left the expense section of my questionnaire empty, which is surprisingly common. I can’t tell you how many people come to me asking if they can retire without knowing how much they spend, i.e., burn rate.
