<prompt> Human: Many people advise that you should pay off the loan with the highest interest rate first, but what if you have a large loan with a lower interest rate and a small loan with a higher interest rate such that the large loan is accruing more interest than the small loan despite the lower interest rate? Is there any case where you would want to pay the loan with the smaller interest rate? If so, how do you calculate which loan you should be paying?edit: Should you try to keep the loan balances at proportional ratios to their respective interest rates? For example, loan 1 is 20,000 at 4, loan 2 is 15,000 at 6. 4:666, so if loan 2 is more than 66 of loan 1, it would be more efficient to put money towards loan 1.  <response>: No. Think of each dollar individually. If 1 of Loan A is accruing 0.24 of interest per year, and 1 from Loan B is accruing 0.12 per year, which dollar should you pay off? It doesnt matter how many dollars you have in each loan, just which one is best to pay off first. You might want to use a different strategy if you prefer the psychological boost of paying off a loan entirely, if a loan has the potential for retroactive interest if it isnt paid off by a certain date, or if you are prioritizing freeing up cash flow over saving interest.
