First, you’ll probably want to experiment with more than one variable withdrawal rate tool. I like the web calculator best. But other calculators exist too, including a simpler variable withdrawal option at and Bob Herlien’s variable withdrawal rate spreadsheet (available here). And we probably all get better insights into the flexibility we need to show if we run lots of simulations using different approaches. is an independent comparison platform and information service that aims to provide you with the tools you need to make better decisions.

What programs like Doomsday Preppers have accomplished, or at least contributed to, is turning sometimes well-informed, sometimes totally unwarranted paranoia into a booming prepper-industrial complex. Each year, swap meets pack hundreds of convention centers and fairgrounds across the nation—they’re like camping shows with a dose of military surplus and hands-on instructional sessions. The September 2017 Kansas City Survival Expo & Gun Show, for instance, had tips on seed saving, “Overcoming 900 Health Diseases” and “A Devastating Street Self-Defense System.” The latter was taught by Norman Cantwell, who inspired Patrick Swayze’s character in Roadhouse. You get the feeling that he and Steven Seagal would be friends. 
Again, the reason we tend to look sideways at those who get a little too into prepping for an apocalypse is because of their smug optimism. People actually being realistic about a dangerous future would be better served joining the military or ingratiating themselves with high-level government officials than agonizing about a little mouth scuzz or foot fuzz, right?
He points to the cash registers over his left shoulder. “I’ll bet you there’s not one thing you bought today that didn’t use electricity in the transaction,” he says. Before Y2K, Finelli says he owned a small computer manufacturing company and personally upgraded 8,000 operating systems so the dates would roll over from 1999 to 2000. “Because they wouldn’t,” he says. “There was a defect. I know that computer systems are frail because I built them.” He says a widespread power outage would cripple us—no electricity, no trading debt portfolios, no buying wholesale taquitos on credit.
