Here's the August 1st update to to my Prosper.com late loan statistics charts.
These charts show statistics for the performance of all prosper.com loans. Each curve represents the set of loans that were created in one calendar month. The vertical axis is the fraction of those loans that have "gone bad", in other words are 1 month late or worse (up to and including default). The horizontal axis is the observation date. All data comes from Prosper.com's performance web page.
A larger, more readable version of that chart can be found here
Here's a chart of the same data in which each curve has been slid to the left to a common origin. The horizontal axis is now days since loan origination month.
Explanation of methodology can be found in my prior postings in this blog.
These curves show loans that are >1 month late, however, you can read them as "default curves" because almost all Prosper.com loans that go 1 month late move on to default. See my discussion of Prosper's collections performance in earlier blog entries.
