Why the minimum takes so long
A card minimum is mostly interest. On $30,000 at 24.99%, about $625 of the first $925 payment is interest, so only about $300 touches the balance. That's why every extra dollar matters: all of it goes to the balance.
Snowball or avalanche?
With more than one card, the snowball pays the smallest balance first for a quick win; the avalanche pays the highest rate first to save the most interest. The difference is often smaller than people expect, and a first card paid off early is what keeps people going.
