Does your nest egg have an expiration date? (Ad)

A $250,000 nest egg growing at 5% a year and paying out $2,500 a month runs dry in just over a decade. Start with $150,000 and it's gone in under six years. A new Prudential survey of more than 3,000 Americans over 50 found 86% don't feel free to spend their savings on things they enjoy. Tim Plaehn, who has advised investors since the 1980s, is tracking a monthly income fund built on major U.S. companies that pays cash without requiring investors to sell shares.tc pixel
