Debt Snowball Calculator

About Debt Snowball Calculator

The snowball method ranks debts by BALANCE, not rate: minimums on everything, every spare dollar at the smallest debt, then roll its freed payment into the next — a deliberately 'suboptimal' order that wins because debt payoff is a behavior problem wearing a math costume. The defaults ($25k across three debts, $900/month) clear the first debt within months — and that early win is the entire psychological engine. The research is unusually clear here: studies (including Kellogg/HBR analyses of payoff behavior) find people who clear entire ACCOUNTS early are significantly more likely to finish, even when the avalanche order would save more interest — because each closed account converts abstract discipline into visible progress, and quitting mid-journey costs more than any ordering inefficiency. The snowball buys completion probability with interest dollars; for most humans, it's a good trade. Compare your numbers against the avalanche calculator beside this one: when the interest difference is small (rates within a few points of each other — common), snowball wins on psychology free of charge; when a 29% card sits among 7% loans, the hybrid most planners actually recommend applies — kill any TOXIC-rate debt first, snowball the rest. And protect the engine: the 'rolled' payment must actually roll (automate it the day a debt dies), and minimum-payment creep on the untargeted debts is why the budget input here, not willpower, is the system.
