Jeez, a whole room full of smart (or at least educated) people and half of them see "10% returns" and get completely wrapped around the axle. Use your brains a bit - the same concept applies at whatever return you happen to think is reasonable. Adjust the numbers appropriately, and you're all set. For example, a 4% withdrawal rate would have let retire into the teeth of the Great Depression and gone another 30 years without working a day. Adjust for your circumstances a bit, and you can make it last forever. Or get a little bit clever with variable withdrawal rates and you can increase the rate and make it last forever. https://en.wikipedia.org/wiki/Trinity_study https://en.wikipedia.org/wiki/Trinity_study
