<prompt> Human: I cant find many resources or calculators online that compare loans of different lengths, but the common theme is that it is usually beneficial to pay off the higher interest loan first I know the snowball method is also preferred. But what if the lower interest loan has a longer term? Shouldnt that make a difference?For example: 4.25 with balance of 13k, 10 years vs. 3.25 with same balance but 20 year terms. Would it make sense to put extra money toward the 20 year loan, being that the interest will compound twice as many times?Are there calculators or spreadsheets available that could help map which would have a greater affect?  <response>: But what if the lower interest loan has a longer term? Shouldnt that make a difference?This doesnt make any difference. It may seem counterintuitive, but the interest you pay depends on how much debt you have today, not twenty years from now. Reducing your debt today reduces the interest you pay today, and in the future, regardless of the time to pay off the debt.
