Variations of the debt-snowball method:
Some financial advisors suggest a variation in which the debts are listed in descending order according to the interest rate that is charged. The idea is to reduce the debts that are growing the fastest in order to minimize the total amount of interest paid. Others recommend paying the debts that cause the most worry or stress.
Ultimately, the best choice depends on the situation and outlook of the debtor. Those who are unsure of their ability to stick with the plan may want to pay the smallest debt first, because the thrill of eliminating an entire balance sooner may encourage them to continue. If an interest-free loan from a sibling or parent has gone unpaid for so long that it threatens to destroy a relationship, it would be a logical first choice for repayment.
