Loan Rate Balance Order Cleared

How it works: minimums are paid on every loan, then the extra (plus any freed-up payments from loans already cleared) is funneled to the loan with the highest rate until it hits zero. Interest compounds monthly at each stated rate. Note: figures assume balances and rates stay as shown and exclude any accrued-but-unbilled interest that posts when repayment starts. The servicer payoff quote is the authoritative number. This is a planning estimate, not financial advice.
