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.

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, and in forum discussions on the old prosper forum, now archived at www.prosperreport.com
Many of the earlier posts in this blog are still on point, and provide background on prosper, from a lender's perspective. If you're new to this, please read old posts before sending questions. Thanks.
On June 1st, Prosper.com made their fifth try at submitting an acceptable registration statement to the SEC that will enable Prosper to reopen. Good luck Prosper. This is a huge document, and I've just about given up on following the changes. With each version it appears that they're becoming more like Lendingclub. Other opinions welcome.
Great discussions among P2P and Prosper.com lenders are found on prospers.org.
