Debt Payoff

Avalanche vs. snowball

Two structured ways to pay off multiple debts. One saves you the most money; the other is built to keep you motivated. Neither is wrong.

Avalanche vs. snowball

Same debts, two payoff orders: cheapest math vs. earliest win.

Avalanche

Highest interest rate first

Least interest paid

Snowball

Smallest balance first

Fastest first win

This is general information, not personalized financial advice — the right approach depends on your specific debts, interest rates, and what actually keeps you motivated. Both methods below share one rule: keep making the minimum payment on every debt, and direct any extra money toward just one of them at a time.

Avalanche method

Pay minimums on everything, then put every extra dollar toward the debt with the highest interest rate, regardless of balance. Once that one is paid off, roll its payment into the next-highest-rate debt, and repeat.

This is the mathematically optimal order: it minimizes the total interest you pay over time, since the debt costing you the most per dollar gets eliminated first.

Snowball method

Pay minimums on everything, then put every extra dollar toward the debt with the smallest balance, regardless of interest rate. Once that one is paid off, roll its payment into the next-smallest debt, and repeat.

This isn't the cheapest path mathematically, but knocking out a full balance quickly creates a visible win early, which can make it easier to stay consistent over months of payoff.

Same four debts, two different orders

Example: a $4,000 card at 24% APR, a $1,500 card at 22%, a $6,000 personal loan at 12%, and a $12,000 student loan at 6%. Here's the payoff order each method produces.

OrderAvalanche — by rateSnowball — by balance
1Card A — 24% APR, $4,000Card B — $1,500, 22% APR
2Card B — 22% APR, $1,500Card A — $4,000, 24% APR
3Personal loan — 12% APR, $6,000Personal loan — $6,000, 12% APR
4Student loan — 6% APR, $12,000Student loan — $12,000, 6% APR
Which one fits you? If you're motivated by the math and can stay disciplined without seeing quick wins, avalanche will save you more money over the life of your debts. If you've tried debt payoff before and lost momentum without visible progress, snowball's early wins may be worth the extra interest cost to actually finish. Some people use a hybrid: snowball on one small debt for an early win, then avalanche for the rest.

Either method works better once you know where your money is going each month — see Budgeting to find the extra dollars to put toward either strategy, and Mindset & Beliefs for why avoiding debt matters beyond the math.
