Americans owe $1.1T in credit card debt at 24.5% average APR in 2025 (Fed), with 47% carrying balances month-to-month amid BNPL explosion and student loan restarts. This 1,200-word playbook compares avalanche (math) vs. snowball (motivation), exploits 0% intro offers, consolidation traps, and a 12-month $20k erasure blueprint for cards, medical, and personal loans—saving $5k+ interest.

| Card A | $3k | 25% | 1 | 3 |
| Card B | $5k | 18% | 2 | 2 |
| Card C | $2k | 12% | 3 | 1 |
Avalanche: 22 months, $3,800 interest.
