How does the debt snowball choose a first target?
Distinguish the smallest-balance method from the highest-rate method.
Watch the briefing
Full briefing transcript
Five hundred dollars, fifteen hundred dollars, and three thousand dollars: the snowball chooses the five-hundred-dollar balance as the first extra-payment target. It ranks balance size rather than interest rate. In our fictional example, the smallest balance carries ten percent, while another debt carries twenty-five percent. Those facts do not disappear. The method chooses a different order; it does not turn the ten-percent debt into the most expensive one.
Required payments still come first. A needs twenty-five dollars, B forty-five, and C seventy in this invented monthly model. That is one hundred forty altogether. With the same three-hundred-dollar total budget, one hundred sixty remains for extra repayment. A gets twenty-five plus one hundred sixty, or one hundred eighty-five. B gets forty-five and C seventy. Together the payments remain exactly three hundred, not an extra three hundred.
Calculate the first month under the same simplified interest assumptions. A adds four dollars seventeen, then receives one hundred eighty-five, leaving three hundred nineteen dollars seventeen. B adds thirty-one dollars twenty-five and receives forty-five, leaving fourteen hundred eighty-six dollars twenty-five. C adds forty-five and receives seventy, leaving twenty-nine hundred seventy-five. Compare what happened to each balance, not just how satisfying the largest payment looks on its own.
With these fixed inputs, A ends month two at one hundred thirty-six dollars eighty-three. In month three it adds one dollar fourteen, so one hundred thirty-seven dollars ninety-seven finishes that debt. The unused part of A's planned payment moves to B in the same modeled month. B receives ninety-two dollars three. This closure is a result of our exact example, not a prediction for a viewer's changing card statement.
Closing a smaller account sooner can make progress easier to see. That possible motivational benefit is different from modeled interest cost. While extra goes to A, B's higher-rate balance receives only its required payment and continues accruing interest. Whether a plan is useful also depends on whether its payments are feasible and consistently made. Do not claim that the order alone proves lower cost, better credit, or an outcome for every household.
To recognize the snowball, ask what determined the first extra-payment target: the smallest balance, not the highest rate. Keep required payments on the other debts, and decide what happens to a payment when its target is finished. Distinguish the smallest-balance method from the highest-rate method. This is general education, not individualized financial advice. The next briefing compares their total modeled interest under exactly the same budget and terms.
Practical takeaway
Distinguish the smallest-balance method from the highest-rate method.
