Debt Snowball vs Avalanche
Compare two proven payoff methods: avalanche saves the most interest, snowball builds the most motivation.
TL;DR
- List every debt with its
balanceandinterestRate. - Avalanche pays the highest
interestRatefirst. - Snowball pays the smallest
balancefirst.
How Both Methods Work
List Your DebtsWrite each balance, its rate, and its minimum payment.
Card $3k/24%, loan $9k/6%Pay All MinimumsCover every minimum first to avoid fees and damage.
All minimums first, alwaysAttack One DebtSend all your extra money to a single target.
Extra $300 -> one debtFind the ExtraFree up a fixed monthly amount to power either method.
Budget $300/mo above minimumsThe Avalanche Method
Highest Rate FirstTarget the debt charging the biggest interest rate.
Pay the 24% card firstSave the MostThis order cuts total interest paid the fastest.
Lowest total interest costBest for Big RatesIt shines when your interest rates vary widely.
22% vs 6% = avalanche winsStay DisciplinedIt needs patience, since the first win can take a while.
Slower first win, bigger savingsThe Snowball Method
Smallest Balance FirstTarget the smallest balance you owe first.
Pay the $800 debt firstQuick WinsEarly payoffs build real, visible momentum.
First win in weeks, not yearsBest for MotivationIt keeps you going when willpower runs low.

No new debt during payoffTips
- Choose avalanche to save the most money, or snowball for faster wins, but keep every
minimumPaymentcurrent either way. - When you clear a debt, roll its payment into the next one, so your
payoffAmountsnowballs larger with each win.
Warnings
- Do not switch methods every month; the best strategy is the
payoffPlanyou will actually stick with to the end. - Never stop paying
minimumson other debts while attacking one; a single missed minimum triggers fees and score damage.
In Practice
Compare both methods on real debts and choose the one that fits.
You have $600 a month for debt across three balances at different rates.
- List debts: $800 at 0%, $2,000 at 24%, $5,000 at 6%.
- Pay every minimum, then send all extra to one target.
- Avalanche: attack the 24% card first to save the most interest.
- Roll its payment onto the 6% loan once it is cleared.
You save the most interest by killing the 24% card first.
Avalanche saves money; snowball saves motivation. Pick one and finish.
FAQ
Both pay minimums on everything and put extra toward one debt. The avalanche targets the highest interestRate first to save the most money. The snowball targets the smallest balance first for quick, motivating wins. The math favors avalanche; behavior often favors snowball.
Avalanche saves more in interest, sometimes a lot on big balances. But snowball's early wins keep many people going, and a plan you finish beats a cheaper plan you quit. Pick the one that matches whether you are driven by math or by momentum.
Each time you pay off a debt, you add its payment to the next debt's minimum. Your payment grows at every step, so payoff accelerates like a snowball rolling downhill. Both methods use this rollover; they just differ on which debt comes first.
Compare rates. If a debt's interestRate is above roughly 8%, paying it off is a guaranteed return that usually beats investing. Below that, splitting between payoff and investing can make sense, especially after capturing an employer match first.
