Compare avalanche vs snowflake strategies and find the fastest path to debt freedom
This tool compares two popular strategies for paying off multiple debts faster: the avalanche method and the snowball method. Both assume you keep making the minimum payment on every debt and then direct one extra payment toward a single target debt each month. The difference is which debt you target first, and that choice affects both the interest you pay and how motivated you stay.
The avalanche method targets the debt with the highest interest rate first, which is mathematically the cheapest path because it kills your most expensive interest soonest. The snowball method targets the smallest balance first, which delivers quicker psychological wins as accounts disappear. In both methods you pay the minimums on all debts, then apply your extra payment to the chosen target. When that target is cleared, its old payment rolls into the next target, and the freed-up money snowballs forward.
Suppose you have three debts: a $2,000 balance at 22 percent, a $5,000 balance at 12 percent, and an $800 balance at 6 percent, with $200 a month extra to accelerate payoff. Under avalanche, you attack the 22 percent card first because its rate is highest, saving the most interest overall. Under snowball, you attack the $800 balance first because it is smallest, clearing an account quickly for a motivation boost. Avalanche usually costs less in total interest, while snowball often feels easier to sustain. The right pick depends on which keeps you paying consistently.
Enter each debt's balance, interest rate, and minimum payment, then enter the extra amount you can add each month. The calculator orders your debts by the method you choose, applies minimums plus the extra to the target, and shows the payoff timeline and total interest for both avalanche and snowball so you can compare them side by side.
The projection assumes you make every payment on time, add no new debt, and keep the extra payment steady, which real life may disrupt. It does not model variable rates, promotional teaser periods, fees, or minimum payments that change as balances fall. Balance transfers or consolidation could change the math entirely. The best method is the one you will actually follow through, so weigh the interest savings against your own motivation.
Which method saves more money? Avalanche typically saves more interest because it eliminates the highest-rate debt first. The gap depends on how different your rates and balances are.
Why would anyone choose snowball? Clearing a small balance quickly creates momentum and a sense of progress, which helps many people stay committed long enough to finish.
Do I stop paying minimums on other debts? No. You always pay every minimum to avoid late fees and credit damage, and you add the extra only to your current target.
What happens when a debt is paid off? Its former payment, minimum plus extra, rolls onto the next debt in line. That growing payment is what accelerates the later debts.
