How to Pay Off Credit Card Debt (Avalanche vs. Snowball)

Face the actual numbers first

List every card: balance, APR, minimum payment. Then run the worst case — what minimum-only payments cost. A $5,000 balance at 24.99% APR with a $150 payment takes 58 months and about $3,622 in interest; at minimum-only, it stretches for many more years. The Credit Card Interest Calculator will show your version of that sentence.

This step is uncomfortable on purpose: the payoff plan works only when the cost of staying put is visible.

Before extra payments: stop the bleeding

No payoff plan survives new debt. Three moves, in order: stop adding charges to the cards (delete saved card numbers everywhere), build a $1,000 mini emergency fund so surprises do not go back on plastic, and pay every card’s minimum on time — late fees and penalty APRs can erase a month of progress in a day.

Avalanche vs. snowball

Both methods pay all minimums and throw every spare dollar at one target card. Avalanche targets the highest APR first — mathematically optimal, every dollar kills the most expensive debt. Snowball targets the smallest balance first — psychologically powerful, because closing an account early is fuel.

Real example: $1,200 at 27.99%, $4,800 at 22.9%, $18,000 at 4.5%, with $900/month total available. Avalanche (store card first) saves the most interest; snowball still clears the small card in two months, which is why people stick with it. Run both orders in the Debt Payoff Calculator and pick the one you will finish — a finished plan beats an abandoned optimum by thousands.

• Avalanche: highest APR first — cheapest in total interest.
• Snowball: smallest balance first — fastest early wins.
• Either way: when a card dies, roll its payment into the next one; total monthly payment never drops.

Accelerators worth considering

A 0% balance transfer (typically 3–5% fee, 12–21 months) pauses interest — treat the promo window as a deadline, not a vacation, and check whether the post-promo rate makes it a trap. A side income dedicated 100% to debt shortens timelines dramatically because it does not touch your living budget.

Calling the card issuer to request a lower APR works more often than people expect, especially with a solid payment history. Ten minutes, one phone call, possible permanent discount on every remaining dollar.

Staying out after you get out

The month the last card hits zero, redirect the entire payment into savings before lifestyle can claim it — the spending was already in your budget, so nothing changes except the destination. The emergency fund guide is usually the right next stop.

Keep one card for credit-score purposes, paid in full monthly, with the autopay set to statement balance. The card becomes a payment method again instead of a lender.
