One of the questions I often get is what should my net worth be at a certain age. There are a lot of factors that go into it, but for those that are looking for some tool where they can get a general idea of where others are at their age and income, this may be of use (or at least of some interest)

Look at the numbers with caution - just because that is where the median happens to be, that doesn't necessarly mean the number is good (think this way: if you have $6000 in credit card debt and the average is $8000 -- yes, you are doing better than average, but it still isn't all that good)
