The short answer: Order debts from highest APR to lowest, pay minimums on all of them, and send every extra dollar to the highest-rate debt until it is gone, then roll that payment to the next.
A practical way to start
List debts by APR
Rank every debt from the highest interest rate to the lowest, regardless of balance.
Pay all minimums
Keep every account current so the plan does not create late fees or damage while you focus.
Attack the highest rate
Send all available extra money to the top-rate debt until it reaches zero.
Roll the payment forward
Move the freed payment to the next highest rate so momentum builds as you go.
Why avalanche can save the most interest
Interest grows fastest on the highest-rate balances, so clearing those first removes the most expensive future interest. Over a long payoff, the avalanche often saves more money than the snowball. The size of the savings depends on the gap between your rates and how long the payoff takes.
Why it can feel slower
If your highest-rate debt also has a large balance, the first payoff can take a while, and early motivation matters. Some people stick with a plan better when they clear a small balance quickly. The best method is the one you will actually follow to the end.
Avalanche, snowball, or a hybrid
You can start with one small snowball win for momentum, then switch to avalanche order to minimize interest. What matters is choosing an order, keeping every minimum current, and staying consistent long enough to judge the results.
Keep the plan honest: Use real due dates and amounts. The tool can organize the information, but it does not move money, pay providers, or guarantee a result.
