Illustrative calculator. Calculations assume constant payments and do not consider prepayment penalties.
The avalanche method directs extra money to the debt with the highest interest rate first. It is mathematically optimal — you will pay less total interest and become debt-free sooner (or at the same time for a lower cost).
The snowball method attacks the lowest balance debt first, regardless of rate. It takes longer and costs more in interest, but generates quick psychological wins that help maintain motivation — especially when you have many small debts.
Academic evidence mathematically favors the avalanche method. However, behavioral finance studies suggest the psychological motivation of the snowball method causes more people to actually complete their payoff plan. The best method is the one you will actually stick to.
