Prosper Stats
The charts in this first section deal primarily with the Prosper market as a whole. Things like membership and loan growth, listing activity, bidding trends and interest rate history. Great for seeing how the Prosper market has grown and changed over time.
Shows Prosper membership growth over time for the last two years. Also shows lender and borrower growth on a monthly basis compared to general Prosper membership numbers.
Shows Prosper loan growth over time for the last two years. Both cummulative loan growth as well as month-by-month originations are shown.
How do Prosper loans perform as they age? Are today's loans any better than loans from 2 years ago in terms of safety? The two charts on this page attempt to provide an apples-to-apples comparison of late rates over time.
Plots the interest rate history for Prosper loans of each credit grade over time. Useful for determining what the current market rates are for each credit grade (and how they've changed over time).
Graphs listing volume month-by-month on Prosper along with listing success rates for group and non-group loans. You can also drill down by credit grade to see how Prosper is doing at attracting borrowers with good (or bad) credit.
This chart shows raw day-by-day bidding activity on Prosper over the last 180 days, with a 14 day moving average to smooth out the daily differences and reveal the actual bidding trends.
Lender Stats
Who are the largest lenders on Prosper? Who are the most active lenders? Who are the new up-and-comers? How many small lenders are there vs. medium or large lenders, and how much influence do these groups have in the market? These are all questions that the charts in this section will help you understand.
Shows how lender performance on Prosper breaks down based on EricsCC ROI. This should give you some idea of what the typical return for a Prosper lender has been historically. Also provides options for breaking down the data set further and viewing additional information.
Shows the top 10 lenders by amount invested. For lots more information about these (and other) lenders, check out the lender list tool
This graph shows the top ten bidders (just most bids, they don't have to be winning bids) over the last 30 days.
This graph shows the top ten bidders (just most bids, they don't have to be winning bids) since Prosper's inception.
Groups Prosper lenders into various brackets based on how much money they have invested in Prosper loans, and shows how much of the overall Prosper lending activity is controlled by those groups.
Group Stats
Although not as influential as they used to be, groups still have a role to play on Prosper. Here you'll find some interesting group-related statistics.
A quick list of the largest Prosper groups by dollars loaned. For lots more information about groups, try using the group list tool.
Theoretically, being a member of a good group should reduce the rate that a borrower must pay on their loan. This chart puts that assertion to the test. It shows the average borrower rate for members of a group vs. the average borrower rate for other members.
One thing that being in a group does appear to help with is getting your listing funded. This chart shows which groups are best at getting their listings funded, with options to break it down by credit grade as well.
This chart is very similar to the one above with one important distinction - it doesn't penalize a group for a borrower who needs to relist their loan multiple times before getting funded. Overall, this is probably a more fair measure of a group's funding performance.
Borrower Stats
The information in the screens below focus on borrower related data. Although this data is about borrowers, it is primarily useful to lenders looking for general default statistics or more data about particular kinds of borrowers.
New - Lates By Payment
If a loan goes late, when does it typically happen? If a loan has gone for 12 months without being late, could you consider it to be "safe" at that point? This graph shows how the default risk for loans changes as they age. Great for helping to evaluate loan pricing in a loan-resale market (should Prosper ever come out with one...)
Shows how late and default rates are changing as loans age. This is done by breaking loans down by credit grade and by age to show what the typical default rate is for each grade of loans at various points in their lifetime (3 months, 6 months, 12 months, etc.)
Ever wonder how a borrower's occupation, homeownership, home state, or income range plays into their risk of default? This report allows you to break borrower listings up into segments by any one of a list of attributes and examine the performance of each segment relative to the others.
This report shows all currently open listings that were created by borrowers who have previously borrowed on Prosper. This includes both those who have paid off a previous loan and those who have another still-open loan.
This report shows the top 25 or so currently open listings with the most endorsements. This may or may not be useful for anything, but they might prove to be interesting to check out anyways.
