Here's the full report from the EBRI for those of you interested in reading that sort of thing.
Not sure how to view these stats. I'm sure the average person wants to spend the same or more in retirement. But, for example, I wouldn't 'need' a car in retirement, so I could cut 20% of my budget. I'd consider that a significant decrease.
There are other examples, like I would expect to dip into savings before 50 (because I plan on retiring), but that would show up looking bad on their graphs because it would indicate taking retirement funds before retirement.
I would sum up that many of these graphs speak to the bad finances of a normal person, but don't apply to mustachians.
