<prompt> Human: Just a quick question, does anyone or has anyone if they had the means done daily payment on an auto loan like a recurring payment? For example Ive seen the every two weeks payment option rise in the past couple of years. What if you took this to the extreme and did each week, or even each day? Lets say an auto loan of 30,000 with a 3.15 interest earned daily. Payments go towards interest first, followed by principle. Is this just a dumb idea, or would the savings be miniscule?  <response>: What my credit union suggested to me was to make any additional payments on the same day that my normal payment was due; this ensures 100 of my extra payment goes to principle.
