Credit card optimizer
What this is
Which card do you hammer first? Math says highest-rate, behaviour says smallest-balance.
Avalanche (highest rate first) is mathematically optimal. Snowball (smallest balance first) is behaviourally easier because you see early wins. This calculator shows both, you pick the one you'll stick to.

Anyone keeping a credit-card balance month-to-month should consider a balance transfer card (0% intro APR for 6-12 months) or a lower-rate LOC for consolidation. Run the numbers both ways.
