Noticed a weird thing. Obvs, making the weekly payments and the loan is being whittled away bit by bit (yay). Except, I've been noticing that my principal payments are going up - ever so slightly - even as my interest payments are going down.
Anyone know why this is. I would expect, if anything, principal payments to stay constant while the additional interest payment on top would fluctuate. And yes, I checked interest rates - principal payments have been rising (again, really really slightly) even as the interest rates and interest payments have stayed the same or fallen.
