This is better
Not better at all - get rid of the smallest loan first so your cashflow increases to both increase your monthly income and then your loan payments to the larger loans.
not at all
the increased monies that are available to pay off the debts by paying smaller first, far outweighs the monies owed for the short time at higher interest.
worked well for me.
Build momentum - This is the way.
Otherwise, you're going to be waiting a long time to see a dent in that highest-rate debt balance. You'll get bored with the lack of progress and lose interest (so to speak).
