Kiva in July 2007, right about the time they blew up on Oprah and got all their loans 100% funded. Since then I have circulated the money to 16 different people, which is quite a few more than the 'average' kiva lender, although this is probably down to the fact that most people loan once or twice and quit out. That's a lot of people to contribute to and help in some some small way.
Kiva provides some useful statistics on your account. Turns out I have been mostly lucky in delinquency rates and default rates, because until recently none of my loans had been delinquent or defaulted.
Now for the less than good news: my luck ran out and I went from a default rate of zero to way past the average when a single organization that was managing a couple of my loans went under and I lost about $100. Sad faces. Per Kiva the average default rate is 1.33%, and my default rate went from zero to 8% overnight. This is disappointing but what can you do? Nothing is guaranteed, life is uncertain, etc and so forth. I'm about to re-lend the money I have in my account now. Let's do this!
