How do money markets work? Specifically Paypal's.
They say the average yield is 5.04% per 7-day period. Why is it measured in 7-day periods? Flipping through the prospectus it looks like the average yearly return is around 3%.
I don't get it.
Do I earn 5.04% once a year? Once a month? 3% once a year?
Enlighten me
