Group Ratings

What are group ratings?

A group's rating is a measurement of that group's performance in paying back its Prosper loans. Specifically, the group rating is an expression of a group's performance against expected (historical) default rates.

"Expected default rates" are based on Experian historical default rates, which are available to lenders on every bidding page.

	Not yet rated Groups are not rated until they have at least 15 total payments billed or at least one late payment
	1 star Underperforms expected defaults by 60% or more
	2 stars Underperforms expected defaults by 20% - 60%
	3 stars Performs within 20% of expected default rates
	4 stars Outperforms expected defaults by 20% - 60%
	5 stars Outperforms expected defaults by 60% or more
