For a number of reasons, I recently asked my credit card company for a credit limit increase. I was hoping they'd propose a new limit to me, but they instead the reverse happened: they asked how much I wanted. I decided to play it conservative; the new limit puts me at under 50 percent peak utilization, but I suspect I could have asked for more and gotten it.
So now I'm looking for data relevant to that problem. I hear stories of people who rack up tens of thousands of dollars in credit card debt, way above my current credit limit. But they could just be racking up over the limit fees and interest. What I suppose I really care about is the average credit limit in the US. To eliminate some outliers and keep the question broadly relevant, what I really want to know is: what's the optimal available credit for the median income household in the US?
