Why does the avalanche method cost less than the snowball method?

It sends every extra dollar to the balance with the highest APR first, so the balance that grows fastest shrinks first. The snowball method targets the smallest balance first regardless of its rate, which builds momentum but leaves the most expensive debt accruing interest longer, so it costs more in total interest over the life of the payoff.

What if a card's APR changes mid-plan?

A promotional APR that expires, or a penalty APR triggered by a missed payment, changes what that card costs to carry. Update the ledger's APR the moment it changes and re-check the payoff order — the avalanche order is only correct when every APR in the ledger is current.

Does closing a paid-off card hurt a credit score?

It can, mainly by raising credit utilization and shortening average account age, both scoring factors. The monthly review includes a keep-or-close decision for every card that reaches zero so that trade-off is made deliberately, not by default.

What happens once the last card reaches zero?

The ledger's total balance reaches zero, the monthly review has nothing left to reconcile, and the plan is complete. The final step compares the actual payoff date and total interest paid against the original projection.

Pay off credit card debt with the avalanche method

A working payoff system — every balance, APR and minimum captured in one ledger, creditors ordered by interest rate, one extra payment automated against the top target, and a monthly review that rolls freed-up payments forward until the last balance clears.

Who it's for

People in the U.S. carrying two or more credit card balances at different APRs who already make at least the minimum payment on each card and have room in their monthly budget for an extra payment toward principal.

About this playbook

Pay off high-interest credit card debt using the avalanche method — order balances by APR, attack the most expensive one first, and roll each freed-up minimum payment forward into the next target. This program guides you through building a complete debt ledger, evaluating balance-transfer and hardship-program options, setting up automated payments, and executing a monthly review routine that keeps the plan on track. Each month you reconcile balances, confirm payments, check for rate changes, and adjust the extra-payment amount as debts clear. It does not cover budgeting, credit-score repair, or negotiating with collection agencies.

What you need first

A statement (paper or online) for every open credit card, online banking access to each card's issuer portal, and a checking account that already covers every card's minimum payment with room left over for an extra payment toward principal. Not for a reader who cannot cover minimums, is in collections, or needs a debt-management plan.

Common questions

Glossary

Avalanche method: A debt payoff strategy that orders every balance by APR, pays the minimum on all of them, and directs every extra dollar at the balance with the highest APR until it reaches zero, then rolls that payment to the next-highest.
APR: Annual percentage rate — the yearly cost of carrying a balance on a credit card, including interest and, depending on the card, certain fees, expressed as a percentage.
Penalty APR: A higher interest rate an issuer can apply to a card after a missed or late payment, which can persist for months even after payments resume on schedule.
Balance transfer: Moving a balance from one card to another, usually one with a lower or promotional APR, in exchange for a one-time transfer fee.
Statement balance: The balance shown on a card's most recently closed statement — the figure the minimum payment is calculated from, as distinct from the live running balance shown day to day.
Roll-forward: The moment a card reaches a zero balance and its freed-up minimum and extra payment are added to the next-highest-APR card's extra payment.
