I have a non credit card question. I understand how interest works and kind of remember amortization from college, though I'm not fully sure what way my student loan is done. I have two loans that were consolidated together, though they show separately but together. The interest rate is the same on both, 2.875. It's been awhile since I looked to see what the individual balances were so I just looked (I know, exciting Saturday night here paying bills, haha). The interest paid from my payment each month is different. One month it's over 70, another it's under 40, under 50, under 60. There doesn't seem to be any rhyme or reason for the differences in the amount of interest is coming out of the payment. I always pay the exact same amount each month and have been for quite some time. Any ideas?
