Multiple Student Loans Payoff Order Calculator
The optimal payoff order for multiple student loans depends on whether you prioritise minimising total interest or clearing individual loans quickly for motivation. Enter each loan above and the calculator generates both avalanche and snowball orderings so you can pick the strategy that fits your financial goals and temperament.

This payment is below the of interest the balance accrues each month, so the debt grows instead of shrinking.
Of this month's payment, comes off the principal and covers interest.
Interest accrues daily, so the number on a payoff quote is only good for the day it was issued — ask your servicer for a dated 10-day payoff quote before you send a final payment.
Building Your Personalised Payoff Queue
Start by listing every loan with its current balance, interest rate and minimum payment. The calculator ranks them two ways. Under avalanche ordering, the loan with the highest rate sits at the top of the queue and receives all available extra dollars while you pay minimums on everything else. Under snowball ordering, the smallest balance takes priority instead, regardless of rate.
The difference in total interest between the two orderings tends to grow as the rate spread between your loans widens. If one loan sits at 3% and another at 8%, the avalanche advantage is substantial and easily quantifiable. If all your loans are within a point of each other, the savings gap narrows considerably and the faster emotional payoff of snowball may matter more than the modest math advantage of strict rate-first ordering. The rate-vs-balance comparison page walks through the decision framework in more detail.
Factoring in Loan Type and Protections
When your list includes both federal and private loans, loan type adds another dimension to the ordering decision. Federal loans carry protections, including income-driven repayment plans and potential forgiveness pathways, that private loans do not offer. Some borrowers deliberately prioritise paying off private loans first to eliminate the debt that offers no safety net during a financial setback, even if a federal loan happens to carry a slightly higher interest rate.
There is no single universally correct answer because the right order depends on your income stability, career plans, forgiveness eligibility and risk tolerance. The avalanche-vs-snowball tool models the pure math of both methods, while the avalanche calculator focuses specifically on the rate-first strategy. Run the numbers here using the tool above, then decide which combination of cost, speed and security fits your financial life best.
The calculator models both orderings side by side. You can adjust the extra monthly amount to see how increasing or decreasing it shifts the payoff timeline.
