<prompt> Human: I currently have 2 loans: a brand new mortgage 320k 4.875 which started this month and a Line of Credit 95k 10.15 variable. I did some calculations online and I realized that even though the LOC is higher interest, putting extra payments towards the mortgage would save me more interest. Im confused as to why this is happening. Shouldnt the higher interest be more expensive and therefore the first to pay off?Thanks for your help guysgals  <response>: Nope your math is off. Doesnt matter if the mortgage is 2,000 or 2 million. The higher interest loan costs you more per dollar and should be paid off first. It also doesnt get any tax benefits.
