Cards are simple interest on a shrinking balance. If the payment does not cover the monthly interest, the balance never falls. Related: snowball vs avalanche · 0% balance transfer · debt-free playbook.

Interest is APR ÷ 12, added before the payment. If the payment does not exceed that interest, the balance does not fall. Ignores late fees, penalty APRs, and 0% promo windows. Educational only.
