I have been lending some money to people through Kiva microfinance to help alleviate poverty since 2007. While reinvesting some funds that were paid back, I noticed that I just reached $1,000 in money lent out through 40 loans of $25 each. Kiva loans do not pay any interest. Out of the $1,000 that I have lent out, I have received about $805 back, about $185 is outstanding, and I have lost about $10. Now, you should know that the people borrowing this money are paying interest rates much higher than zero but much of that interest goes back to paying operational costs and covering defaults. There has been some debate as to whether this is becoming a form of predatory lending, but I believe there is a real need for such lending in these countries. You also have to trust Kiva in their selection of MFI field partners. I also do microfinance lending at Microplace.
Right now you can get a free $25 trial to try out Kiva using my invite link (I get nothing). You basically get to make a free $25 to a person of your choosing from a developing country, but when it is paid back you the money goes back to the sponsor. I know, rather cheesy. I think you should just have to keep lending it out by making it ineligible for withdrawal. That’s what I like about this type of lending – the money you commit can help many people over time.
