Debt snowball vs avalanche: which method actually wins?

Compare debt snowball and avalanche with real interest math. When psychology beats APR, and when 28% cards make the choice obvious.

The two rules

List every non-mortgage debt with balance, APR, and minimum. Pay every minimum so nothing goes delinquent. All extra cash hits one target.

Snowball: smallest balance first. You collect quick wins. Avalanche: highest APR first. You collect the least interest.

When the math is not close

A $1,200 store card at 28% next to an $11,000 student loan at 6% is not a personality test. Kill the 28% first. That is avalanche, and it is also common sense.

Snowball shines when you have five small medical bills and a history of quitting plans. Finishing something is a feature.

Do not starve the rest of the plan

Keep a one-month cash buffer so the next surprise does not restart the card. Keep the employer 401(k) match. Everything else can wait until the expensive debt is gone.

Questions

Which method saves more money?

Avalanche (highest APR first) always saves more interest if you stick with it. Snowball (smallest balance first) wins only if it keeps you paying extra at all.

Should I pause investing to pay debt?

Keep any 401(k) match — that is a 50–100% return. Pause optional brokerage while cards are over ~8–10% APR. Mortgage-rate debt is a different conversation.

What about balance transfers?

A 0% transfer can beat both methods if you can clear the balance before the promo ends and the fee is smaller than the interest you would have paid. Do the math, then freeze the new card.
