I had this figured out before but it really wasn't worth my time. What i did was take the current loan rate, whatever that is and divide it by 365 days then each day take that number and add it to the current G fund price, which changes minutely each day, and when it finally goes up to the next penny, that's when you get the penny. The rated changes monthly.
Let's say the rate is 4.5%. Multiply that by the current price of the G (11.56) and then divide that (.5202) by 365 (.001425205) and then add that to the price of the G fund each day and when it goes up another full penny, pay the penny...............
It's just a pain the rear. Plus it's off once in awhile because you don't really know where the G is when you start. Is it 11.56, 11.5600236, 11.560000001...........:blink:
