How this is calculated
Every debt always receives at least its own minimum payment. The extra payment — plus the minimum payments freed up from any debt you've already paid off — goes entirely to a single "target" debt at a time: the smallest balance first (snowball) or the highest interest rate first (avalanche). Avalanche always results in equal or lower total interest for the same debts and extra payment; snowball can be motivating because you clear individual debts faster, even if it costs a bit more overall.
