<prompt> Human: Hi friends, first of all some backstory. Im 18, just out of highschool, with a decent job for now. I purchased a motorcycle with my fathers co-sign and the payments are about 100 a month. For the sake of curiosity, how much would it hurt memy father to go maximum 3 days late on paying a months payment on this bike? Everything Im finding on google is just talking about 306090 day late payments, which isnt something I need to know.  <response>: As a starting point you may owe a late payment fee might be 20-40 so substantial relative to payment and on an interest basis, some extra interest, and it is up to the lender what to do on reporting, etc. Many wont report 30 days.So the answer is: it depends but it will be a very expensive loan for 3 days since the late payment fee would be steep.
